However, restrictor plates were not initially used for Camping World Truck Series trucks. I know there is al. During the early days of stock car racing, more horsepower ultimately meant more wins. The deployment of these flaps eliminates most of the lift on the vehicle. Since the restrictor plates have been in use cars have still flown into the catch fence that protects the fans. The speed limit depends on the size of the track and the size of pit road. NASCAR requires spotters at all times a car is on the track, including series in practice, qualifying, and the race. The first flap oriented 140 degrees from the centerline of the car typically deploys first. The Iowa Speedway is the first track that was built with the SAFER Barrier around the entire track. In the transitional years (197176) where the seven-litre engines (430 cu in) had restrictor plates, Daytona and Talladega broke 40 official lead changes six times, while Michigan International Speedway broke 35 official lead changes in both of its 1971 races.

The 2011 Sprint Cup season was the last complete Cup season with carbureted engines; at the end of the 2011 season, NASCAR announced that it would change to an electronic fuel injection system for the 2012 racing season. (The 2010 Aaron's 499 had 88 lead changes, but the 88th the race-winning pass by Kevin Harvick was on the last lap of the third attempt at a green-white-checkered finish). Combined with the aerodynamic disadvantage of the trucks, this allowed NASCAR to avoid the use of such equipment for the trucks until 2008. The arrival of the Next-Gen car in 2022 marks the dawn of a new era for the NASCAR Cup Series.

NASCAR's restrictor-plate tracks cause drivers and fans to play a dangerous game NASCAR drivers Kevin Harvick, Ricky Stenhouse Jr. and AJ Allmendinger were all involved in a crash on the final.

Starting in 2015, the majority of NASCAR tracks have SAFER Barriers surrounding the entire perimeter of the outside walls. [11] The introduction of carbon fiber seats has also helped improve safety, as carbon fiber absorbs more energy from an impact than the traditional aluminum seats. [5] The NASCAR Xfinity Series also introduced a new generation car in 2011 (trialled partially in 2010), featuring the same safety improvements. NASCAR's Monster Energy NASCAR Cup Series and Xfinity Series have used restrictor plates at Daytona International Speedway and Talladega Superspeedway since 1988. .
