(CNN)Here's some background information about NASCAR, the National Association of Stock Car Auto Racing.
It is the main governing body for stock car racing in the United States.
NASCAR is the creation of William H.G. (Bill) France, a stock car driver and gas station owner.
Stock cars are large, late model sedans that have been built especially for racing.
The stock car's large engine allows it to reach speeds exceeding 200 miles per hour.
Most stock car races are held on oval asphalt tracks. The distance of race tracks can vary from 1/8 of a mile to 2 3/5 of a mile.
NASCAR runs three national series: the Sprint Cup Series, the top series, the XFINITY Series, the second series, and the Camping World Truck Series, which is for racing trucks only.
There are 36 races on the Sprint Cup schedule: twenty-six in the regular season and 10 post-season.
Restrictor plates, which slow cars down, are used at Talladega and Daytona International Speedways, because of the high banks found at both tracks. They were used for the first time in 1971.
NASCAR has varying colored flags, with different meanings, to direct drivers:
- Green: Signals the beginning of the race and any restarts.
- Yellow : Signals an accident or debris caused by contact or mechanical failure, or weather-related issues. The track is not clear. Slow down and hold your position behind the pace car.
- Red: Cars must go to a designated location and stop immediately due to a safety issue.
- White: There is one lap remaining in the race.
- Black and White Checkered: The race is over!
Richard Petty has the most career wins of any racer, with 200 wins. He is known as the "King" of stock-car racing.
Richard Petty and Dale Earnhardt Sr. are tied for the most Cup championships, with seven each.
Jimmie Johnson is the only NASCAR Cup Series driver to win five consecutive championships (2006-2010). He won in 2013, so his total is now six.
Dale Earnhardt Sr. earned 76 Cup Series wins and is the all-time race winner at Daytona International Speedway, with 34 wins.
