The National Association for Stock Car Auto Racing ( NASCAR ) creates and enforces many rules and regulations that go beyond all racing series.
NASCAR issued a different rule book for each race series; however, the rule book is published exclusively for NASCAR members and is not publicly available. However, many rules, such as the scoring system, have been widely published by NASCAR and the media.

Each car is required to display its number on each car door and on its roof. The front of the car and the bottom of the rear bumper are required to match the decal specifications of the car manufacturer. Each car is required to display a series of approximately 30 decals of NASCAR sponsors just to the left of each door and on the front fender. This contingency sticker represents the series sponsors and bonus money team entitled to get during the race, but can be eliminated in events where they conflict with team sponsors or moral convictions. Series sponsorship logs are displayed on top of the windshield, called front windshields or windshield banners.
Starting in 2013, the livery layout for the NASCAR Cup Series was changed, coinciding with a change to the 6th Generation model car. Instead of the series sponsorship as in the lower series, the windscreen clearly displays the driver's last name (as well as the first name or initials in case you as well as for Busch's brothers, or suffixes for drivers like Dale Earnhardt, Jr. and Martin Truex, Jr.) placed in the center of the windshield header. The logo of the manufacturer is placed in every corner of the top windshield. Number and sponsor logos are prohibited from being placed on headlamps and taillights, as they do not preclude the unique characteristics of each car model. A new location for a single sponsor logo, however, is added to the back of the roof adjacent to the number. In 2014, a new layout is created for participants at NASCAR Chase for Championships, which requires the car to display yellow roof numbers, front separators, and front fascias. The background of the windshield header will also be yellow, with the driver's name displayed in black letters. The new Chase for the Championship logo will replace the normal NASCAR Cup Series logo in the contingency group. A sticker will also be placed next to the driver's name above the door to signify every win earned by the driver that season. For 2015, the Xfinity series and Camping World Truck series will feature the driver's last name in the upper rear window. Starting in 2017, the Monster Energy logo is now on the windshield with the driver's name moving to the rear windscreen in the NASCAR Cup Series Energy Monster.
Beyond this requirement, the team can design cars and place sponsored logos at locations approved by NASCAR, and must submit all paint and graphic schemes and all sponsored identities to NASCAR beforehand for approval. One requirement of a paint scheme for example is that both the driver and passenger side of the car should share the same color pattern, although the front and back may have different colors. This security rule, to avoid confusion for complainants, NASCAR officials, and other drivers, became clear in October 2014 at Talladega, when Go FAS Racing team Terry Labonte painted the title No. 32 cars in two different color schemes as a tribute to the champion twice, but prior to NASCAR approval. NASCAR allows teams to retain the scheme for knock-out qualification, but forces them to match both sides for the race. However, by 2016, it appears NASCAR has quietly deleted this rule or allowed teams to race with a split-side scheme provided they get permission to do so, as seen with John Hunter Nemechek No. 8 trucks at American Ethanol E15 225 in 2016 and both No. 3 and No. 31 cars from RDV CompÃÆ'Â © tition during 2016 NASCAR Whelen Euro Series.
The team applies to NASCAR for the use of car numbers, and pays for the rights to similar numbers. NASCAR legally owns and controls all rights to car numbers. When the driver changes the team, the team owner usually maintains the number. Unlike in other series, like the former IROC Series, there is no provision for defending series champions or leader points to adopt car number 1; it is available to any team. Only one number, No. 61, at the Whelen Modified Tour, has retired, to commemorate the nine-time series winner Richie Evans, who died at Martinsville Speedway training for the final race of the 1985 season. Other historically significant numbers have been formally retired except with the driver's permission or team owner. Number 3, for example, used by Dale Earnhardt and owner of his car Richard Childress, has been unlawfully retired for all teams and drivers except for Earnhardt or Childress family members, with Childress paying the license fee while the number is out of circulation since 2001. until 2013. In other cases, some people have been released because the sponsor left the team. After the 2002 season, Robert Yates Racing switched from number 28 to 38 after the Texaco-Havoline sponsors stopped their sponsors.
The team can run numbers from 0 to 99 (as well as 00 to 09), but no two cars can display the same number during the race. Teams running from 00 to 09 are listed as 100 to 109 for NASCAR assessment purposes. Except for those numbers (which have been used for full-time teams), part-time teams can be assigned a three-digit number only for goalscoring purposes (such as No. 141 and 241). If the two teams arrive with the same two-digit number, the higher teams in the championship points apply, and the other team will be forced to change their number for the race.
Maps NASCAR rules and regulations
Sponsors
Tobacco
Although NASCAR has a long history of tobacco sponsorship, after the 2003 season, NASCAR's old partner, R. J. Reynolds refused to renew their Winston sponsorship of the Cup Series, replaced by Nextel Corporation. In June 2010, the Food and Drug Administration passed a new regulation that prevents sponsorship of tobacco or smokeless tobacco products at every sporting event, including car racing events. The announcement affects two teams: Truck No. 33 Ron Hornaday, Jr. and Kevin Harvick, Inc. lost the sponsor of the Longhorn Moist Snuff, while the National Serie No. car. 27 from Baker Curb Racing lost Red Man's sponsorship. Baker Curb will close its doors next year due to lack of sponsorship.
Regardless of the legislation, tobacco sponsorship continues in sports through electronic cigarettes, with companies like Green Smoke, blu (owned by R.J. Reynolds), and Arrowhead sponsoring the NASCAR team. A smokeless smokeless tobacco brand, Smokey Mountain, also sponsors drivers like Hornaday, Johnny Sauter, Brian Scott, and Daniel Hemric.
Viceroy Rules
Although NASCAR typically promotes competition between multiple brands, including those that sponsor sports and individual races, the sanctioning body provides exclusive protection for title series titles, such as Monster Energy in the Cup Series, as well as Sunoco's current fuel supplier. This policy, known as the Viceroy government , prevents sponsorship of direct competitors in a particular series, although that does not prevent companies from moving to different series in sports, or advertising products that are not directly conflicted with title sponsors. For example, Royal Dutch Shell, Texaco, and other oil companies were allowed to promote their motorcycle brands (Pennzoil and Havoline respectively) but not their gasoline products. When new title sponsors create conflicts with existing team sponsors, NASCAR usually allows team sponsors to stay under the grandfather clause. This rule is named after the Viceroy brand of British cigarette, and refers to the 1972 USAC Car Championship season where the title sponsor Marlboro left the branding when Viceroy entered the sport to sponsor the entry.
This rule has prevailed on several occasions, especially when Nextel Communications signed a $ 700 million ten-year deal to replace Winston as a Cup Series sponsor. Cingular Wireless's active sponsor (sponsoring the No. 31 team of Richard Childress Racing) and Alltel (sponsoring the No. 12 car from Ryan Newman's Penske Team) were allowed to continue their transactions, but both sponsorship agreements were questioned when the company was bought and searched for re-branding. In 2004, Robby Gordon was asked to wear a full-colored Nextel patch on his clothes. He has been wearing a dark gray on the black Nextel patch which subdued when he was sponsored by Cingular during the race for RCR. Between 2007 and 2008, NASCAR and AT & amp; T Mobility (Cingular's successor) filed a lawsuit against each other, with NASCAR trying to kick all the telecom companies out of the top series. AT & amp; T was allowed to remain in the sport until 2008. Meanwhile, Verizon, after buying Alltel in 2008, transferred its sponsors to Penske entries in the Xfinity Series and then IndyCar Series, while the team ran a similar scheme in the Series Cup without Verizon branding until 2010. In separate incidents in 2007, Robby Gordon was allowed to retain his sponsorship from Motorola mobile phone manufacturers after adding logos referring to the company's "Digital Audio Players".
Custom rule for race combinations
The combination race is a race that runs between several series operating under a package of compatible rules. During the NASCAR combination race (currently two Series C & N Pro (East and West), and formerly Winston Cup/Winston West Series and Busch/Busch Series Series), there is one race, but the points are scored for both series. In previous years, drivers were given points based on how they completed among the competitors of the same series. For 2017, drivers will receive points in their series based on their final results in races among all competitors. However, drivers who claim they are running for the championships in both series (East & West) will be awarded points in both series, provided they have the appropriate license for both.
Custom rules apply because two teams will have the same number. The fastest lap time in qualifying determines which team will have the race number, and which team should change the numbers for the temporary race. For example, during the 1991 Busch Series season, there were races selected in the Northeast (Loudon, Nazareth, Dover, Oxford) where both Busch Grand National (now Xfinity) and Busch Grand National North (now K & amp; N Pro East) Series race in a combination race. North Team Ricky Craven (also drove his car) and Grand National Don Beverly Racing team (Jimmy Hensley driving) both use No. 25. Anyone who has a faster qualifying time in every race used. 25. Craven using No. 28 at Oxford when Hensley had a faster time, while Hensley used No. 5 when Craven had a faster time at Loudon. Both teams, however, scored their respective owner points for No. 25 in each series.
Cars and drivers changed
The team must use one car from the beginning of the first training session to the end of the race. The team that crashed the car in training or qualifying can go to a spare car, but racing a different car from a qualified car produces a car that should start at the back of the field.
Engine and transmission changes are prohibited during the race weekend. Xfinity and Truck Series engines have to endure two race weekends, excluding racer plate races. Changing the two will produce a start at the back of the field. Transmission changes are permitted during weekend highways and during race weekend at Pocono Raceway. In addition, during Speedweeks at Daytona the team allowed one free engine change between the qualifying races and the final training session.
Driver changes are allowed, but starting a race with a different driver than a qualified car will result in a car starting at the back of the field. Driver changes during the race are also allowed, done during the pit stop, but the team must experience a loss in position due to the time spent swapping drivers. The driver who started the race got all the points, stats, and money on the wallet.
Flag warning and restart procedure
When the yellow flag is displayed and the yellow warning light around the track starts to fire, the field will freeze immediately upon warning. All assessments end soon and the car should slow down the vehicle speed (safety car). The car will line up behind the speed vehicle in the order in which they pass the last rating loop on the track (there are as many as 18 rounds on the track, although the one at the start/finish line is the only one that counts for official racing statistics). The exception to this rule is if the yellow flag is wavy after the white flag is thrown (or, in the case of overtime attempts, if the yellow flag waves after the race leader passes the overtime extension line) or if the race will not restart (usually for rain, but sometimes for darkness if the track does not have a nightlight), in this case NASCAR will use video proof to determine the final order.
When caution came out, the pit lane was soon closed, the rule was first applied after Atlanta 500 in 1989. This was shown by a flashing red light at the entrance to the pit road. Entering the pit road when closed (with certain exceptions) is a penalty to restart behind the field. When the pit lane opens, a stable green light will appear at the entrance to the pit road, and the green light will light up in the vehicle's speed back window.
During "quickie yellow" all the cars can enter the pit road first when opened. After the pit stop, the first car one lap below when the warning (known as a free pass car) was allowed to get around the speed car and start the race behind the field, but back on the front lap.
As long as it is full of yellow, only the main lap car can complain the first time with the pit road. After the main lap car that has decided to pit has entered the pit road, a free pass car will be sent around the speed car to get their rounds back. Next time with, all cars (including free pass cars) can complain.
Cars can pit as often as they want at the expense of track positions, but free pass cars are limited to picking up fuel only on the first pit stop occasion. If a free pass car is judged to have caused caution (intentionally or not) there will be no free pass pass.
At signal one to go, the car speed will turn off the lights. At this point, any car in front of the race leader will wave to the back of the field. These cars are not allowed to pit until after the green flag comes back out and the race has returned. This column will then compile the double file to restart. The race leader gets a choice of paths, but the third place car (and odd positions in the back) will always start at the inner line, while the fourth place car (and even the rear position) will always start in the outer lane. The restart sequence is always this: Lead Lap Cars & gt; Car 1 or more laps down & gt; Free Pass Car & gt; Wave Around & gt; Car that has received a penalty.
Once the car quickly enters the pit, there is a "zone" restart consisting of lines painted on the outer wall of the track. The race leader will start accelerating inside this zone to continue the race. Otherwise, the flagman controls the restart. The second car may not be in front of the leader at the time of the green flag, but the car in the front row can cross the start/finish line first. Escaping is not allowed until the racial leader crosses the line early on. Line change is also not allowed until after the car clears the finish line.
As per the NASCAR rule book, restart is official after the car leads the law across the start/finish line. If the green flag is waved, but NASCAR cancels the restart because of an incident before the leader passes the start/finish line, the restart is considered canceled.
Championship point system
Flag
Like most other sanctions agencies, NASCAR will use flags to provide drivers with information regarding track conditions. NASCAR, does not follow FIA rules (although NASCAR is a member club of ACCUS, US motor sport racing authority and representative of the FIA ​​World Motor Sport Council), does not use the flag system outlined in the FIA ​​International Sporting Code. The main differences include that in NASCAR (and other championships in North America) white flags are used to signal that leaders are in the final round, the FIA ​​ISC organized events (such as Formula One and most European championships) are used to signal that more cars slowly on track. Also, the blue flag specified in the ISC FIA does not have a diagonal line, and the black flag means that the driver is disqualified.
Qualification procedure
Standard procedure
Knockout systems similar to Formula One are used. During the allotted time, teams are allowed to make unlimited efforts to qualify with the fastest lap of each round count as their official time.
Among the efforts, the car was parked on the pit road, where the team could connect the cooling system through a flap cal in front of the windshield to cool the engine. However, teams are not allowed to raise the hood or make other significant adjustments during qualifying. Also, tires can not be changed without the consent of NASCAR, which will only give consent in case of a flat tire or security issue.
On all of the open engine ovals on the NASCAR Cup Series Energy Monster, the track is shorter than 2 miles on the Xfinity Series, and the track is shorter than 1.5 miles in the World Truck Camping Series, round 1 is 20 minutes. 24th fastest progress to round 2 which is 10 minutes long. 12 fastest forward to round 3 that determines pole position. In addition to determining who goes to round 2, round 1 also determines who will and will not qualify for the race and 25-40 starting position (Cup Series), 25-40 (Xfinity), or 25-32 (Camping World Truck). Likewise, lap 2 will determine the starting position of 13-24, with round 3 determining positions 1-12.
On a road course, there are only two sessions: Round 1 is 25 minutes with the top 12 rising to Round 2 being 10 minutes.
If rain falls between rounds, NASCAR has the option of declaring the session over and the speed from the previous round will be calculated for all remaining positions.
divider plate tracks, more than 2-mile oval on Xfinity, and oval again from 1.5 miles on Truck
Due to how the draft works in racing license plates, and a series of accidents in qualifying during 2015 Speedweeks, a single car qualification format is used for racetracks of bounding plates. In July 2015, after making auto change regulations designed to improve drag and drafting, NASCAR used formats in Indianapolis and Michigan (but stopped its use in both tracks for 2016). The single car system will only be used on plate tracks, ovals 2 miles and longer in the Xfinity series, and ovals 1.5 miles or more in the Truck series.
In round 1, the car is sent one by one to the NASCAR officer. Each car has one heating lap, one lap futures, and one cold spin. NASCAR will release cars about half a lap apart to prevent aerodynamic gains from being earned from competing cars. The order in which the car drove is the opposite of the speed of the exercise. As well as the road course format, the top 12 cars advance to the final round.
After the last car returns to the pit road in the first round, all 12 qualifying teams can connect the cooling system to the car for 10 minutes. Round 2 cars will pass from the slowest to fastest based on their speed from round 1. The fastest car will win the pole.
Terms of Daytona 500
The session results from a single-car qualifier set up the starting lineup for the Can-Am Duel race on Thursday. Duel race race two 60 round/150 miles. The first race consists of those who completed qualifying in odd numbered positions and set the lineup for odd-numbered positions at 500. The second race did the same for even-numbered positions. However, there must be an equal number of "open" or "non-charter" teams in each Duel race. After the Duel race, the lineup is set as follows:
- Position 1-2: The two fastest qualifiers in a single car qualifier on Sunday.
- Position 3-38: Results of the Duel race, which consists of all the highest charters and charter teams in each Duel.
- Position 39-40: Two fastest cars from non-charter teams that have not qualified, based on Sunday's qualifying session.
Temporary rule
The three NASCAR national series will establish a certain number of starting positions with scheduled laps and have a certain number of preliminary positions based on unqualified vehicle owner points.
- Energy Monster NASCAR Cup Series: 36/4
- Xfinity Series: 33/6/1
- Camping World Truck Series (except Eldora): 27/4/1
In the NASCAR Series Monster Energy four positions are awarded to the team's fastest qualifying open. In the Xfinity Series, six positions are awarded based on owner points for unqualified cars. In the World Truck Driving Series, four positions are awarded based on owner points for trucks that are not yet eligible.
The last position in the Xfinity Series and the World Camping Truck Series is reserved for the previous series winners. Any past champion can use this champion's past six times per season. If past past champions are not required, then a position to the first team at the owners points has not been eligible for the race. If the former team of champion racers is one of the top six or four teams, respectively, the highest in owner points, not yet qualified, then it does not count against temporary use. If there are 40 or fewer (or 32 or less) vehicles entered in the race, there is no temporary charge and the field will be determined only by the lap of time.
After this position is given, the car is set based on lap times.
Past champion
In 1991, NASCAR introduced the provisional former champion (sometimes known as the "Petty rule") after Richard Petty failed to qualify in four races in 1989. This special provisional allows the former Cup winner to claim the starting position if he is too low in the standings points and can not qualify with speed. Past champions last worked perfectly until 1997, when Darrell Waltrip failed to make the UAW-GM Quality 500 lineup because Terry Labonte was the newer and higher champion in points. NASCAR is considering revising its guides for past champions past after Waltrip used them to enter 20 races in 1998. In 2004, NASCAR gave the Cup champions past a maximum of 10 previous championship periods per season; this amount was reduced to six in 2007. This proved to be a disaster for Dale Jarrett in 2007, when he moved to Michael Waltrip Racing beginner with no owner points and failed to qualify in 12 races after being forced to use all his past champions earlier in the season. Past champions have been discontinued from the NASCAR Cup Series Energy Monster as part of the new Charter system and qualifying system in 2016.
All-Star Week Qualification
Open using standard procedures, but only 8 cars that go to the final round. All-Star racing qualification consists of a combination of 3 laps with a 4-tire pit stop. 5 fastest riders in the opening round advance to the final round.
Eldora
Aspen Dental Eldora Dirt Derby has a unique qualifying format. Each truck will take two laps of time, with a faster lap count as the official time of the truck. The trucks are assigned to one of five hot races where the top five trucks of each will advance to the feature. Those who fail to qualify will have one last race chance, where the top two trucks will also go. Provisional will be determined after the last race.
Daytona Clash
The Advance Auto Parts Clash is an annual race of special invitations held by the weekend before Daytona 500, and sets its ranks via random draws.
Penalty
NASCAR conducts a full technical inspection before the first training session, before and after qualifying, and before the race. A quick security check is also completed before each training session after the first. Punishments for car offenses are usually announced Wednesday after the race, and can range from simple fine to suspension (usually a maximum of 12 races) and loss of points. After the race, the top 5 racers, one other random car, and the first car that failed to finish the race not because of a car accident will be checked. The winners, random cars, and first cars out also have cars and engines taken by NASCAR for further inspection at the NASCAR Research and Development Center. Furthermore, there is one random race per year in which NASCAR confiscates 15-20 machines and takes them to the NASCAR Research and Development Center for evaluation, comparison, and to help decide future rule changes.
Starting in 2017, NASCAR will try to spend more penalties over the weekend of the race instead of waiting until Wednesday. Now there will be punishments L1 and L2:
- L1 penalizes areas with minimum altitude and weight, Laser Inspection Station (LIS), gear ratio, and flashy wheel wheel violations where 17 or less are secured correctly. The penalty will be a 10-40 point deduction, a suspension for 1-3 races, plus a fine of up to $ 75,000.
- The L2 penalty involves heavier offenses related to disruption to three "no-man" technical areas in the field of tires, engines and fuel. Major safety violations, telemetry use or traction control, plus a testing policy violation are also included in the L2 assignment. This penalty will be a 75 point deduction, 4-6 racing suspension, and a fine of up to $ 200,000.
- "Burdened" is over: Rules allow the victory to stand in the event of a foul, but the winning team will lose the benefits associated with victory.
- A list of pre-race fines in the weekend of the race at the disposal of the series director, in order to increase the severity: Loss of "hard card" annual credibility, loss of training time, loss of pit selection, field punishment, green flags on the pit road after start start, stop-and-go green flag in the pit after start, and penalty round.
As a member of ACCUS/FIA, NASCAR has a substance abuse policy that requires random testing of drivers, crew members, and officials. Those who have violated the policy (including suspension for domestic violence) were postponed indefinitely and given the opportunity to enroll in NASCAR's Road to Recovery Program to be replaced back to NASCAR.
Pit path
During the race, the team must complain several times for refueling and new tires. The team allowed five crew members on the wall at the start of the race; which consists of two tire converters, one tire carrier, a jackman, and a gas. After NASCAR delivers OK (usually after the leader starts pounding the car), the 6th crew member is allowed only to serve the driver/windshield. With the changing NASCAR 2018 rules, gas men are now not allowed to make adjustments to cars while refueling.
There is a pit path speed limit set for each race. Because NASCAR cars do not have speedometers, the first lap of each race is run at a pit road speed so the driver can get a tachometer reading for the pit speed. There are various other safety rules (see above penalty) to follow.
At the time of caution or when there are two laps to be passed on stage, pit road immediately closed. NASCAR uses light at the end of the pit road and a series of cameras to help determine when the pit road is closed. Holes are opened after the field is under the control of the speed/safety car unless there is an accident near the entrance/exit or at the pit road, in which case the hole will remain closed until NASCAR considers the safe hole to be opened.
After the June 2015 Chicagoland Xfinity race event in which the pit pitman waves a green but light flag at the red end of the pit road, NASCAR adds light to the rear of the speed/safety car to help alert the driver and team when the pit road opens, and thereby removing the flagman from the entrance of the pit road. The official policy of NASCAR is that if there is a discrepancy, the light at the end of the pit road is official.
Starting in 2017, cars that experience irreparable crash damage at the pit road within 5 minutes will be automatically removed from the rest of the race. Speeding on the pit road will see 15 seconds less time per violation. Furthermore, the team is not allowed to replace the bodywork once the race begins. Teams that use more than 5 crew members will also remove their cars from the race.
Crew Rosters
For the 2018 season, NASCAR created a new roster system. This system will standardize the number of team members tracked. Rosters are divided into three categories: Organizational, Road Crew, and Crew Holes.
Examples of places on the Organization list include competition directors, team managers, technical directors, IT specialists. In the NASCAR Monster Energy Cup Series, teams are awarded three organizational listing points for one and two car operations, and four places for three and four car outfits. XFINITY and Camping World Truck Series teams are allowed one list location of their respective organizations.
Examples of Road Crew include crew heads, car heads, mechanics, engine tuners, engineers, specialists (for areas such as tires, aerodynamics, and shocks) and claimants. Limits for these personnel are based on series: Monster Energy Series, 12; XFINITY, 7; Camping World Truck, 6.
Pit Crews are the same in all series, with a maximum of 5.
Exceptions to these numbers are few. The Monster Energy Series team was allowed an extra road crew position at Indianapolis Motor Speedway and three road programs (Sonoma, Watkins Glen, Charlotte), where teams often use multiple claimants. In addition, additional roster locations for road entourses will be allowed for XFINITY teams in 10 races and Truck Series teams on five.
Racing procedure
Beginning in 2017, NASCAR announced that it was entitled to raise the start of an hour-long race to beat bad weather (heavy rain and street lighting).
Two hours before the race, the driver and the crew chief attend the obligatory driver meeting. Failure to attend the meeting will force the driver to start behind the field. In August 2015, NASCAR announced that it would be experimenting to move the driver's meeting to just an hour before the race as the meetings in most races took less than 15 minutes.
Approximately 30 to 45 minutes before the start time of the race, the driver's introductions will be held. Failure to attend this will also require the driver to start at the back of the field as well.
At the designated start time, a pre-race prayer is given, followed by a national anthem. Once the anthem is over, the driver has five minutes to get into their car with all the safety equipment tied up and ready to go. At the end of five minutes, the grand marshal for the race will give the command "Driver, start your machine!", At which point each car should start the engine. With the engine running, the cars sit on the pit road for about three minutes before heading to the track for some warm-up laps before the race car. The average number of speed vanes is three, but may be more or less dependent on various conditions and conditions, including but not limited to track length, effort of draining the track after rain, or if the car has problems and stops on the track during the speed spin. At the end of lap lap, the field will take part in a scrolling start.
If the last round of the race begins carefully, the race will be extended per NASCAR Overtime. After the track is clear, the field will be given a green flag with two laps remaining. If there is another collision/warning before the leader reaches "overtime track," usually located on the backstretch, then the race will continue to extend until the leader reaches the line. However, when the race leader reaches the overtime line, the next flag (carefully or checkered) will end the race (even though the competitor must cross the start/finish line at the speed of the car to be able to score in their current position carefully).
After the race, the winning driver (and, if at the end of the season, the championship-winning driver) will usually complete a series of blackouts in celebration of their victory, before heading to the winning track for further celebrations and post-race interviews.
Security
Since the end of 2001, head and neck control is required for the use of all drivers. Since 2005, HANS Devices (Head and Neck Support Devices) are the only approved devices. Since 2003, helmets are also needed for pit crew members. The driver and members of the pit crew must also wear firesuits. Racers are required to use carbon fiber chairs and headrests for strength and endurance. The car has also been redesigned since Dale Earnhardt's death in 2001 and after a spectacular wreck to reflect new discoveries and safety developments.
All oval tracks in NASCAR National Series (except Eldora) use SAFER Barrier and other soft wall technologies to reduce impact.
After a series of flipping and dangerous collisions in the 1980s, NASCAR began to require all cars to run the dividing plates in Daytona and Talladega. The boundary plate limits the air to the engine, reducing horsepower and speed in this track from 230-240 mph to 195-200 mph. In this race, next to the limiting plate, there are various other rules and technical regulations to keep the car stable and on track. In addition to this technical rule, the plate divider race is the only race in which the driver is prohibited from using the apron of the track to execute the pass. The double yellow line separates the track from the surface of the race, causing many people to call the "Yellow Rule Rules" rule. Driving below the line to advance one's position is subject to a drive-through penalty, or if a foul on the last lap of the car will be relegated to the last car on the front lap in official race results.
Test
NASCAR has previously approved an annual 4-day preseason test at Daytona International Speedway in January for all teams until 2015, when all personal testing is prohibited. After the test, each organization was allowed to perform four 2-day tests. Each test must be on a different race track. The rookie racer is allocated additional tests. Starting in 2016, each team is eligible to participate in five open tests to be held at Indianapolis Motor Speedway, Watkins Glen International, Chicagoland Speedway, and Homestead-Miami Speedway.
Goodyear tire suppliers are allowed to conduct unlimited testing and can ask which team wants to complete the test. Usually Goodyear selects the top three players from the previous year's event to run the test. However, Goodyear previously conducted a full-field tire test at Indianapolis in late June/early July in preparation for Brickyard 400.
Weekend schedule
The Monster Energy NASCAR Cup Series usually runs a day of training and qualifying on Friday, followed by second practice day on Saturday morning, followed by Sunday's race. If running Saturday night races, the second day of practice is not held. During a deviant race, a three-day schedule was maintained, with qualifying taking place on Saturday.
The Xfinity series will run the drills on Friday, followed by qualifying a few hours before the race on Saturday. If the race takes place on Friday (or the schedule is compressed for other reasons), it is not uncommon for training, qualifying, and competitions for all held on the same day. The Camping World Truck Series usually does this.
Rain can and often affects weekend schedules. At that time, qualifying was routinely canceled and the starting lineup was set by the owner points (last year's points for the first 3 races).
