The fastest lap in Nascar was an average speed of 212.809. This record was set by Bill Elliott in a qualifying lap at Talladega Superspeedway in 1987. This was before restrictor plates were in use.
Cars go a lap down when they get passed by the leader, when the caution comes out, the last car who went a lap down gets a free pass and he can go all the way around to the tail-end of the lead lap cars, thus, putting him/her on the same lap as the leader(s).
The 'Lucky Dog' in Nascar is when the first car a lap down gets its lap back. When a caution comes out, the first car off the lead lap will get a wave around, they will then be able to start at the tail end of the lead pack.
Run the first lap the slowest, speed it up a lot on the 2nd lap, work the hardest on the 3rd lap, and do your best on the last lap (sprint the last 100 meters).
a vessel which keep its course and speed but with caution.
Speed Skating
Advise, caution or issue a speeding ticket.
Some drivers want a yellow flag (caution flag) to come out so that they can get their car adjusted or fueled or whatever without going a lap down. If they did this during a regular green flag lap they would most likely go a lap down. A caution also closes the field up. You're running at Pocono and your car has finally started working with the track. Unfortunately, you're in 19th, there are only 24 cars on the lead lap and the leader's a quarter-mile behind you. If you stay out on a long green-flag run, you're going to be a lap down in a very short time. But if someone cuts a tire and a caution comes out, everyone gets to close up behind the leader...and, with good work in the pits, you may even come out a couple spots ahead.
The California Speedway is now known as Auto Club Speedway. The average track speed reaches over 200 miles per hour while the fastest lap is 241.428 miles per hour.
The fastest single lap (2.5 miles) record was set in 1996 by Arie Luyendyk was a speed of 237.498 mph.
It depends,1. If they are the first car 1 lap down they get the lap back (this is called, "Lucky Dog.") They then are the last car in line and they are back on the lead lap.2. If not the first lap car they just keep their position in relation to the other cars. So if they are 5 cars behind the the first place car, they stay 5 cars behind the first place car.3. If all cars in front of them pit (lapped or not) and they do not then their car would be right behind the pace car on the restart. I have only seen this done a couple times.4. If they choose to pit then they are added to the back in the order they left the pits.Cars on the lead lap get to pit first. Cars a lap or more down have to wait until the second caution lap that the pits are open. So if all cars on the track pit then all lapped cars are behind the cars on the lead lap.This only applies to NASCAR. Other racing organisations have different rule regarding this.
the lapped cars starts in the front because they are kind lucky dogs in the race. if you were the first car down a lap, and a caution came out, you'd be the luck dog.
