Yes, Nascar does have traffic lights on their tracks. They are set up at various locations on the track in a horizontal position. The yellow light will come on when there is a caution, the green light stays on while the drivers are racing and the red light is used if the race is red flagged.
When the green flag drops they duck into the pits and park at the end of pitroad, so if a caution comes out or etc. they pull back out on the track and meet the drivers and lead them around.
It is an attempt to finish the race under green flag conditions. If the race ends under caution, they will give the green, then the white flag to signigy one lap, then the checker. Only 3 attempts are made at this, and if a car takes the white flag, one to go, that constitutes a finish.
because human eye is sensitive to yellow and green, it has become a tradition to use red as a signal for caution also red colour has largest longest wavelength
To some NASCAR drivers it is and to some it isn't. For decades the color green has been a superstition in NASCAR. Throughout the years, there have been drivers who adamantly refused to drive a green car.

Not sure, but I don't think you have to worry about going a lap down in a road race, because the lap times are so much longer. You would want to use the caution laps to catch back up to the lead pack.
Nascar's longest race of the season, the Coca-Cola 600, is held every Memorial Day weekend. It's a Sunday race that begins in daylight hours and finishes under the lights at Charlotte Motor Speedway.
