Safety in NASCAR has evolved into one of the biggest concerns in stock car racing's largest sanctioning body. Mainly after the death of Dale Earnhardt, a seven-time Winston Cup Series champion, NASCAR has decided to change all of their safety policies, such as the use of the HANS device. Since 2001, NASCAR has also changed the cars for the NASCAR Cup Series and the Xfinity Series. NASCAR's safety policy includes the racing fire suit, carbon fiber seating, and roof flaps.
During a series of deaths of several drivers, NASCAR began researching a new, safer car. After a seven-year program, NASCAR presented a design for a new car. The new car, known as the Car of Tomorrow, features a reinforced roll cage. The left side skin has a steel plate for better resiliency in crashes. The roof was four inches (10 cm) higher and two inches (5.1 cm) wider for safety in rolls. First implemented in the Car of Tomorrow was the separated wing. From 2009-early 2010, the wing was blamed for several flips. Starting in the 2010 spring Martinsville race, the wing was replaced by the traditional spoiler. [1] Also new to the Car of Tomorrow, is the stronger smaller fuel cell 17.75 US gallons (67.2 L) for a reduced risk of fires. [2] The windshield is made of Lexan which gains its strength from its flexibility. Under normal circumstances, the glass bends and absorbs the force of the object. [3] Implemented in a limited schedule in 2007, the car was immediately criticized by the drivers for lack of handling. [4]
In 2013, a sixth-generation stock car was unveiled, and the Car of Tomorrow was retired, although it retains some technologies from the previous-generation car. [5] The NASCAR Xfinity Series also introduced a new generation car in 2011 (trialed partially in 2010), featuring the same safety improvements. [6]
The Generation 6 was succeeded by the Next Gen car in 2022 (it was initially going to be debuted in 2021, but it was pushed back due to the COVID-19 pandemic). However, in its first year of competition, the Next Gen car gained safety-related controversies as the car's stiffer rear end caused concussions for both Kurt Busch (that turned out to be career-ending) [7] [8] and Alex Bowman [9] in one season. In response, NASCAR announced changes to the rear bumper construction, rear chassis clip, and center chassis clip for the 2023 season. [10]
NASCAR drivers are required to wear a fire-retardant suit and underwear along with certified helmets. This suit serves a dual purpose of identifying the driver outside the car, and protecting them during a fire. The driver also wears fire retardant shoes and gloves. During long races, the heat of the engine might warm the feet to uncomfortable levels, so most drivers wear a heat shield on the bottom of their shoes.
The helmets have many features for both safety and increasing the effectiveness of drivers in the NASCAR circuit. The helmet:
The seats that the drivers sit in have evolved over the past few years. Most of the seats found in the race cars wrap around the driver's rib cage. This provides some support during a crash, spreading the load out over the entire rib cage instead of letting it concentrate in a smaller area. Some of the newer seats wrap around the driver's shoulders as well, which provides better support because the shoulders are more durable than the rib cage. [11] The introduction of carbon fiber seats has also helped improve safety, as carbon fiber absorbs more energy from an impact than traditional aluminum seats.
By 1989, NASCAR had five-point harnesses. Then, they maintained six-point harnesses in 2007 and then the current seven-point harnesses in 2015. [12] After a string of fatal accidents involving skull fractures, NASCAR has made it mandatory for drivers to wear the HANS device, which reduces the risk of head and neck injuries in the event of a crash. [13] NASCAR also allowed the use of the Hutchens device but banned it in 2005 due to test failures. [14]
Following Richard Petty's crash during the 1970 Rebel 400 at Darlington, where his arms and shoulder were dangling out of the car, all cars must have a window net to contain the driver's arms during a crash and to protect the driver from flying debris. [15] The drivers are also instructed to lower the window net after a wreck to signify that they are uninjured. [16]

As a safety measure to reduce speeds at the two high-banked superspeedways (Daytona and Talladega), restrictor plates are used. There are some tracks, however, where restrictor plates are not mandated and therefore see faster speeds—specifically Atlanta Motor Speedway and Texas Motor Speedway. While Atlanta is generally considered the fastest track, restrictor plates are not mandated there. In 2004 and 2005, higher qualifying speeds were posted at Texas, earning it the title of the circuit's fastest track. Unrestricted Sprint Cup cars produce over 750 horsepower (560 kW) and can run at speeds in excess of 200 mph (320 km/h). [17] Rusty Wallace completed a 2004 test for NASCAR at Talladega in which he used an unrestricted motor to complete average lap speeds of 221 mph (356 km/h) and top speeds near 230 mph (370 km/h). The 2010 width is 63⁄64 inch (25.003 mm). This is the largest carburetor restrictor plate opening since the one inch (25.400 mm) mandate in 1988, the first year the horsepower-reducing plates were used in the Cup Series at Daytona. [18]
Unfortunately, the restrictor plates have an unintended effect on the race. Because of the reduced horsepower of the cars, the cars form large packs. During a race it is not uncommon to see thirty or more lead changes during a race. This also is the source of the Big One. When a driver crashes, usually, they take that pack with them. During the 2010 Coke Zero 400, 21 of the 43 cars crashed. This is a safety concern that has puzzled NASCAR. However, an unexpected consequence of the introduction of the Car of Tomorrow and re-paving of Daytona and Talladega track surfaces has been the separation of the pack into two-car pairs.
Since the 2012 season, NASCAR Cup cars now have fuel injection instead of carburetors, but restrictor plates are still being used.
In 1994, NASCAR introduced roof flaps to the car, which is designed to keep cars from getting airborne and possibly flipping down the track. Following Rusty Wallace's crashes at Daytona and Talladega, Penske Racing designed the original roof flaps. [19] NASCAR team owner Jack Roush helped improve on the design of the roof flaps, in conjunction with Embry-Riddle Aeronautical University, Daytona, Florida. [20] During spins, as a result of accidents or loss of handling, as the car rotates it eventually reaches an angle where the oncoming air reacts with the profile of the vehicle in the same manner as a wing. If the speed is high enough air flowing over the car's overall airfoil shape will create sufficient lift to force the car to become airborne. To prevent this, NASCAR developed a set of flaps that are recessed into pockets on the roof of the car. As a car is turned around and reaches an angle where significant lift occurs, the low pressure above the flaps causes them to deploy. The first flap oriented 140 degrees from the centerline of the car typically deploys first. After flap deployment, higher pressure air is forced through an air tube which connects to a second flap, deploying it. This second flap ensures that, should the car continue to spin, no further lift will be created as the vehicle's angle changes. The deployment of these flaps eliminates most of the lift on the vehicle. The roof flaps generally keep the cars on the ground as they spin, alt. [21]
Beginning in 2002 (at Indianapolis), many tracks were retrofitted with SAFER barriers along the walls of the track. These walls absorb the energy of an impact better than concrete walls, while maintaining integrity better than traditional steel barriers. This system costs millions of dollars to install, and the creation of this wall, which connects to the original wall, took many more millions to design and create. Some SAFER barriers were installed in 2003 at Richmond, and Homestead–Miami, others in 2004 at Talladega, Daytona (July, before the 2004 Pepsi 400) and other tracks, in 2005 at Dover and at Watkins Glen in 2010. The Iowa Speedway is the first track that was built with the SAFER Barrier around the entire track. Starting in 2015, the majority of NASCAR tracks have SAFER Barriers surrounding the entire perimeter of the outside walls.
Pit road safety has become a major focus of NASCAR officials in recent years since the 1990 Atlanta Journal 500, where the rear tire changer for Melling Racing was killed in a pit road crash.
By April 1991, NASCAR implemented the current policy of pit road speed limits. The speed limit depends on the size of the track and the size of pit road. NASCAR uses an electronic scoring system, similar to the VASCAR system, to monitor the speeds of cars on pit road by measuring the time it takes to get from checkpoint to checkpoint. The cars are not equipped with speedometers, therefore during the pre-race warm-up laps, the cars are driven around the track at the pit road speed limit behind the pace car. The drivers then select a gear (usually second gear) and observe and record the corresponding RPM on their respective tachometer. [22]
By 1994, almost every form of motorsport had adopted pit lane speed limits, following NASCAR's cue.
NASCAR does not allow the use of pit road specific rev limiters as found in most other forms of racing. Allowing a pit road limiter would require the addition of several electronic components into the car, and NASCAR has long opposed the installation of electronics into cars, citing the decline of open wheel racing once technology was introduced.
Since 2002, NASCAR has implemented a rule where all over the wall pit members are required to wear helmets, no visors needed, full fire suits, and gloves; while the gas man must wear a fire apron as well as the suit. While it is not required yet, it is recommended that tire changers wear safety glasses to prevent eye injuries from lug nuts thrown off the car and fuel spills. Some tire changers wear face shields or goggles.
Beginning in 2008, teams in the top three series may not roll a car more than three pit box lengths to push start a car. This prevents teams from pushing a car the length of pit road when the starter motor fails. Also, outside tires that have been removed from a vehicle during a pit stop can no longer be free-rolled from the outside of the pit box to the pit wall; rather, they must be hand-directed to the inner half of the pit box before being released. [23]
Effective in 2012, teams may not plug a cable that connects an engine control unit to a computer during a pit stop with the car on pit lane. In such cases, the car must be in the garage area for the team to run the cable from the car to the computer. This rule was implemented for the Sprint Cup Series, which switched to electronic fuel injection for 2012. [24] As with changes to car models, NASCAR will institute new rules during a season if it deems it necessary to enhance safety.
In contrast with open-wheel, sports car, and touring car governing bodies, NASCAR does not allow race cars to have wing mirrors. Drivers may still use a rear-view mirror and mirrors attached to the roll bar (a rear-facing camera was also added with the Next Gen car in the Cup Series), but no mirror can extend outside of the car. As a result, they are left with large blind spots. In NASCAR's more prominent series, spotters are used to combat this problem. The spotter's purpose is to relay information about where cars in these blind spots are to the driver via two-way radio. [25] Spotters also advise drivers on navigating track-obstructing crashes and may relay messages from one driver to another. NASCAR requires spotters at all times a car is on the track, including series in practice, qualifying, and the race. In many cases, a spotter is a former driver.
At some tracks, mostly the road courses, NASCAR mandates multiple spotters at key locations around the track.
Talladega Superspeedway, nicknamed "Dega", and formerly named Alabama International Motor Speedway (AIMS) from 1969 to 1989, is a motorsports complex located in Lincoln, Alabama, north of Talladega, Alabama. It is located on the former Anniston Air Force Base. A tri-oval, the track was constructed in 1969 by the International Speedway Corporation, a business controlled by the France Family. As of 2023, the track hosts the NASCAR Cup Series, NASCAR Xfinity Series, NASCAR Craftsman Truck Series, and ARCA Menards Series. Talladega is the longest NASCAR oval, with a length of 2.660 mi (4.281 km), compared to the Daytona International Speedway, which is 2.500 mi (4.023 km) long. The total peak capacity of Talladega is around 175,000 spectators, with the main grandstand capacity being about 80,000. As of 2023, Talladega is one of NASCAR's three drafting tracks, alongside Daytona International Speedway and Atlanta Motor Speedway.
A restrictor plate or air restrictor is a device installed at the intake of an engine to limit its power. This kind of system is occasionally used in road vehicles for insurance purposes, but mainly in automobile racing, to limit top speed to provide equal level of competition, and to lower costs; insurance purposes have also factored in for motorsports.
The GEICO 500 is a NASCAR Cup Series stock car race held at the Talladega Superspeedway in Lincoln, Alabama. The race is usually held in April or May. The 1997 event stands as the fastest NASCAR race to date ever run with an average speed of 188.354 miles per hour (303.126 km/h) and was the first race at Talladega Superspeedway that was not interrupted by a caution period.
The YellaWood 500 is a NASCAR Cup Series stock car race held at Talladega Superspeedway in Lincoln, Alabama, hosting an event in the NASCAR playoffs. The race is one of four NASCAR Cup Series races currently run with tapered spacers, the others being the GEICO 500 in May, the Coke Zero Sugar 400, and the Daytona 500. Through 1996, this race was normally held in early August or late July. In 1997, it was moved to early October due to the uncomfortably hot summer temperatures, and sometimes unpredictable summertime thunderstorms in the Alabama area. In 2009, the race moved again, this time to November 1 as part of a realignment agreement with Atlanta and Fontana.
The Car of Tomorrow was the common name used for the chassis of the NASCAR Cup Series and Xfinity Series race cars. The car was part of a five-year project to create a safer vehicle following several deaths in competition, particularly the crash at the 2001 Daytona 500 that killed Dale Earnhardt.
The National Association for Stock Car Auto Racing (NASCAR) makes and enforces numerous rules and regulations that transcend all racing series.
On the afternoon of February 18, 2001, American stock car racing driver and team owner Dale Earnhardt was killed instantly due to a basilar skull fracture in a final-lap collision in the 2001 Daytona 500, in which he crashed into a retaining wall after making contact with Sterling Marlin and Ken Schrader. He was pronounced dead at Halifax Medical Center a short time later.
A roof flap is an aerodynamic feature on race cars, mainly stock cars, which functions as an emergency spoiler to prevent the vehicle from lifting off the ground. The flaps are stowed during normal vehicle operation; however, in certain situations, e.g., if the vehicle goes into a spin, particularly if it is facing backwards, the flaps deploy to disrupt the air flow over the roof and reduce the lift force on the vehicle.
The 2007 UAW-Ford 500 was the 30th stock car race of the 2007 NASCAR Nextel Cup Series and the fourth in the ten-race season-ending Chase for the Nextel Cup. It was held on October 7, 2007, at Talladega Superspeedway in Talladega, Alabama, before a crowd of 155,000. Jeff Gordon of Hendrick Motorsports won the 188-lap race starting from 34th position. His teammate Jimmie Johnson finished second and Dave Blaney was third.
A spotter in auto racing is a trained team member whose job is to relay information to their driver, keeping them alert of what is occurring on the track. They are typically positioned higher, atop one of the grandstands or other support buildings, to see the entire track. Spotters keep in constant contact with their drivers via two-way radio communication. Spotters are considered the drivers' "eyes" and are one of the more notable yet simple, safety measures adopted by professional auto racing in the past two decades.
The 1987 Winston 500 was a NASCAR Winston Cup Series racing event that took place on May 3, 1987, at Alabama International Motor Speedway in Talladega, Alabama. The race was a turning point in the balance between stock car speed and safety in NASCAR.
The 2015 Daytona 500, the 57th running of the event, was a NASCAR Sprint Cup Series race which was held on February 22, 2015 at Daytona International Speedway in Daytona Beach, Florida. Contested over 203 laps – extended from 200 laps due to a green–white–checker finish – on the 2.5 mi (4.0 km) asphalt superspeedway, it was the first race of the 2015 NASCAR Sprint Cup Series season. Joey Logano won the race, recording the second Daytona 500 win for Team Penske, and his ninth career Sprint Cup victory. Kevin Harvick finished second while Dale Earnhardt Jr., Denny Hamlin and Jimmie Johnson rounded out the top–five.
Beard Motorsports is an American professional stock car racing team that competes part-time in the NASCAR Cup Series with the No. 62 Chevrolet Camaro ZL1 1LE for Austin Hill. The team was created in 2009 by Mark Beard for competition in the ARCA Menards Series. Beard Motorsports attempted two races in the Cup Series in 2014, with driver Clay Rogers, making none. After going dormant in 2015 and 2016, the team returned part-time in 2017 with Brendan Gaughan.
The 2017 Daytona 500, the 59th running of the event, was held on February 26, 2017, and was won by Kurt Busch of Stewart-Haas Racing after Chase Elliott and Kyle Larson ran out of fuel over the final laps of the race. This was Busch's first Daytona 500 win, and his first career win on a restrictor plate track. Ryan Blaney finished second, and A. J. Allmendinger finished third. This race was contested for 200 laps on the 2.5-mile (4.0 km) asphalt superspeedway. It was the first race of the 2017 Monster Energy NASCAR Cup Series season, and also marked the first race for Monster Energy as the new title sponsor for NASCAR's top series, replacing Sprint. Jeffrey Earnhardt made NASCAR history when he became the first ever fourth generation driver to compete in the Daytona 500.
The 2018 GEICO 500 was a Monster Energy NASCAR Cup Series race held on April 29, 2018, at Talladega Superspeedway in Lincoln, Alabama. Contested over 188 laps on the 2.66 mile (4.28 km) superspeedway, it was the 10th race of the 2018 Monster Energy NASCAR Cup Series season.
The 2019 GEICO 500 was a Monster Energy NASCAR Cup Series race held on April 28, 2019, at Talladega Superspeedway in Lincoln, Alabama. Contested over 188 laps on the 2.66 mile (4.28 km) superspeedway, it was the 10th race of the 2019 Monster Energy NASCAR Cup Series season.
The 2020 Daytona 500, the 62nd running of the event, was a NASCAR Cup Series race held on February 16–17, 2020. It was contested over 209 laps—extended from 200 laps due to an overtime finish, on the 2.5-mile (4.0 km) asphalt superspeedway. It was the first race of the 2020 NASCAR Cup Series season.
The Next Gen car, originally known as the Gen-7 car, is the common name for the racecar that is currently in use in the NASCAR Cup Series. Its use began with the 2022 season. A further evolution of the Generation 6 car, the Next Gen features "improved" aero and downforce packages while introducing new technologies on the track. In addition, the Next Gen is designed to lower costs and attract new original equipment manufacturers (OEMs) to compete with Chevrolet, Ford, and Toyota.
The 2021 GEICO 500 was a NASCAR Cup Series race was held on April 25, 2021, at Talladega Superspeedway in Lincoln, Alabama. Contested over 191 laps – extended from 188 laps due to an overtime finish, on the 2.66 mile (4.28 km) superspeedway, it was the 10th race of the 2021 NASCAR Cup Series season, as well as the second of the four crown jewel races. Brad Keselowski won the race, his 35th career victory, sixth win at Talladega, and his last win with Team Penske in the No. 2 as he moved to Roush Fenway Keselowski Racing in 2022.
NASCAR, the highest governing body and top level division for stock car racing in the United States, has used a range of different types of engine configurations and displacements since its inaugural season in 1949. The engines are currently used in the Cup Series, Xfinity Series, Camping World Truck Series, and the Whelen Modified Tour.
