Safety at NASCAR has evolved to be one of the biggest problems in the largest sanctioned racing car buying body. Especially after the death of Dale Earnhardt, winner of the Winston Cup Series seven times, NASCAR has decided to change all their safety policies, such as the use of HANS devices. Since 2001, NASCAR has also turned the car for the Sprint Cup Series and Xfinity Series. NASCAR safety policies include fire racing, carbon fiber seats, and roof coverings.

Car of the Future
During a series of multiple driver deaths, NASCAR began researching the new, safer cars. After the seven-year program, NASCAR presented the design for the new car. The new car, known as the Car of Tomorrow, comes with a reinforced roll cage. Left side skin has a steel plate for better resistance in a collision. The roof is four inches taller and two inches wider for safety in rolls. First implemented in the Car of Tomorrow is a separate wing. From 2009-early 2010, the wing was blamed for some flips. Beginning in the 2010 Martinsville race season, the wings are replaced by traditional spoilers. Also new to the Future Car, is a smaller fuel cell that is stronger 17.75 gallon US (67.2 liters) to reduce the risk of fire. The windshield is made of Lexan which gains its strength from its versatility. Under normal circumstances, the glass bends and absorbs the strength of the object. Implemented in a limited schedule in 2007, the car was immediately criticized by the driver for lack of handling.
In 2013, a sixth generation stock car was unveiled.

Racing shirt
NASCAR racers are required to wear refractory clothing and underwear along with simpson helmets. The lawsuit serves a dual purpose to identify drivers outside the car, and protect them during a fire. The driver also wore boots and fireproof gloves. During long races, the heat of the engine can warm the feet up to an uncomfortable level, so most drivers wear a heat shield at the bottom of their shoes.
Helmets serve many security purposes on the NASCAR circuit. First, the helmet protects the driver from injury. Second, the helmet has a radio connection to communicate with the reconnaissance chief and crew. Third, helmets sometimes have visors that reduce the sun's glare so the driver can have better eyesight. Fourth they have anchor point connected to H.A.N.S. device to reduce the risk of neck injury and concussion in an accident.
Seats
The chairs used by the drivers have evolved over the last few years. Most of the seats found in race cars wrap around the driver's ribs. This provides some support when a collision occurs, spreading the load around the ribs instead of letting it concentrate on a smaller area. Some new seats wrap the driver's shoulders as well, which gives better support because the shoulders are more durable than the ribs. The introduction of carbon fiber seats also helps improve safety, since carbon fibers absorb more energy from impact than traditional aluminum seats.
Seat belt and harness
The safety belt used is a five or six point harness, which has two ropes lowered over the driver's shoulders, two ropes wrapped around the waist, and one or two straps between the legs. Since a series of accidents in 2000 and 2001 that killed Adam Petty, Kenny Irwin, Tony Roper and Dale Earnhardt (plus several other drivers on the small circuit) under the same circumstances, NASCAR has required drivers to use HANS devices. Although NASCAR allows other systems, Hutchens devices, in the past, since 2005 HANS was the only head and neck leverage tool allowed to use. More recently, Hutchens has been allowed again by NASCAR, as seen by its use by Kyle Larson and Austin Dillon. The HANS device reduces the risk of whiplash in the event of a crash.
Window of
All cars must have nylon mesh webs to protect the driver from flying debris and hold the driver's arm in the event of a collision. In addition, drivers are instructed to lower their windows after an accident to indicate that they are not injured.
Limit plate
As a security measure to reduce the speed at two high superspeedways (Daytona and Talladega), the bounding plate is used. There are several tracks, however, where the bounding plate is not mandated and therefore sees a faster speed - specifically the Atlanta Motor Speedway and Texas Motor Speedway. While Atlanta is generally regarded as the fastest path, the limiting plate is not mandated there. In 2004 and 2005, a higher qualifying pace was placed in Texas, making it the title of the fastest track circuit. Without limits, the Sprint Cup car produces over 750 horsepower (560 kW) and can run at speeds in excess of 200 mph. Rusty Wallace completed a 2004 test for NASCAR in Talladega where he used an infinite motor to complete an average speed of 221 mph (356 km/h) and a top speed approaching 230 mph (370 km/h). The width of 2010 is 63/64-inches. It is the largest carburetor divider opening since its one-inch mandate in 1988, the first year of horsepower removal plate used in the Cup Series in Daytona.
Unfortunately, the limiting plate has an undesirable effect on the race. Due to the reduced car horsepower, the cars form large packages. During the race, it is not uncommon to see thirty or more changes leading during the race. It is also the source of Big One. When drivers crash, usually, they carry the package with them. During the 2010 Coke Zero 400, 21 of 43 cars fell. This is a security issue that has baffled NASCAR. However, the unforeseen consequence of the introduction of the Car of Tomorrow and the reworking of the Daytona and Talladega line surfaces is the separation of packages into two pairs of cars.
Since the 2012 season, NASCAR Cup cars now have fuel injectors, not carburetors, but limiting plates are still in use.
Close roof
In 1994, NASCAR introduced a roof flap to the car, designed to keep the car from drifting in the air and possibly flipping the track. After the Rusty Wallace crash in Daytona and Talladega, Penske Racing designed the original roof flap. The owner of the NASCAR team, Jack Roush, helped improve the design of the roof flap, along with the Embry-Riddle Aeronautics University, Daytona, Florida, USA. During the spin, as a result of an accident or loss of handling, because the car spins eventually reach the angle at which the air coming in reacts with the vehicle profile in the same way as the wings. If a high enough air velocity that flows over the entire shape of the car's airfoil will create enough lift to force the car into the air. To prevent this, NASCAR developed a set of hidden flaps into a pocket on the roof of the car. When a car is rotated and reaches a corner where there is significant rapture, low pressure above the flap causes it to spread. The first 140-degree orientated flap from the center line of the car usually spreads first. After the spread of the flap, higher air pressure is forced through the air tube that connects to the second flap, passing it. This second cover ensures that, if the car continues to rotate, no more appointments will be made when the vehicle angle changes. This flap placement removes most of the lifting on the vehicle. The roof flap generally holds the car on the ground while spinning, alt.
SAFER bottleneck
Starting in 2002 (in Indianapolis), many tracks were installed with SAFER barriers along the track wall. These walls absorb energy from a better impact than concrete walls, while maintaining better integrity than traditional steel barriers. The system requires millions of dollars to install, and the making of this wall, which connects to the original wall, requires millions more to be designed and manufactured. Some SAFER barriers were installed in 2003 in Richmond (July), and Homestead, others in 2004 in Talladega, Daytona (July, before 2004 Pepsi 400) and other lines, in 2005 at Dover and at Watkins Glen in 2010. Iowa Speedway is a track first built with SAFER Barrier throughout the track. Starting in 2015, most of the NASCAR tracks have SAFER Barriers that surround all the perimeter of the outer wall.
Pit road security
Pit road safety has been a major focus of NASCAR officials in recent years since the 1990 Atlanta Journal 500, where the rear tire driver for Melling Racing was killed in an accident at the pit road.
In April 1991, NASCAR implemented the current pit speed limit policy. Speed ​​limits depend on path size and pit size. NASCAR uses an electronic scoring system, similar to the VASCAR system, to monitor the speed of a car on the pit by measuring the time it takes to go from checkpoint to checkpoint. The cars are not equipped with speedometers, therefore during the pre-race preheating laps, the cars are pushed around the track at the speed limit of the pit road behind the speed car. The driver then selects the teeth (usually 2nd gear) and observes and records the corresponding RPM on each tachometer.
In 1994, almost every form of motorsport had adopted the pit lane speed limit, following the NASCAR cue.
NASCAR does not allow the use of special pit borders such as those found in most other forms of racing. Allowing a road pit limiter would require the addition of some electronic components into the car, and NASCAR has long opposed electronic installation to the car, citing the decline of open wheel racing once the technology was introduced.
Since 2002, NASCAR has implemented a rule in which all members of the pit on the wall are required to wear helmets, no need for shields, full fire suits, and gloves; while the gas man had to wear his fire apron and suit. Although not necessary, it is recommended that the tire changers wear safety glasses to prevent eye injury from wheel jaws thrown from cars and fuel spills. Some tire changers wear face protectors or goggles.
Starting in 2008, teams in the top three series may not roll more cars than three long pit boxes to encourage starting the car. This prevents the team from pushing the car along the pit road when the starter motor fails. Also, the outer tire that has been removed from the vehicle during the pit stop can not be freely rolled from outside the pit box to the pit wall; instead, they should be directed directly to the inside of the pit box before it is released.
Effective in 2012, the team can not install a cable that connects the machine control unit to the computer during a pit stop with a car in the pit lane. In such cases, the car must be in the garage area so the team can run the cable from car to computer. This rule applies to the Sprint Cup Series, which turns to electronic fuel injection for 2012. As with changes to the car model, NASCAR will create new regulations during the season if deemed necessary to improve safety.
Spotter
In contrast to the open-wheel, sports car, and tour regulator body, NASCAR does not allow race cars to have a rearview mirror. The driver may still use the rearview mirror and mirror attached to the scrollbar, but no mirror can extend outside the car. As a result, they are left with large blind spots. In the more prominent NASCAR series, complainants are used to solve this problem. The goal of the spotter is to convey information about where the cars in these blind places are to the driver via two-way radios. Complainants also advise drivers to navigate crashes that block the track and can convey messages from one driver to another. NASCAR requires complainants every time a car is on track, including the series in training, qualifying, and racing. In many cases, scouts are former drivers.
On some tracks, most of the road programs, NASCAR mandates several claimants at key locations around the track.
