Trivia: In NASCAR’s Cup Series, what marking signifies a rookie driver?
Red hubcaps
Yellow stripe
Green “R” decal
White bumper
The correct answer is Yellow stripe
So why is this answer correct? : The NASCAR equivalent of a “student driver” sign is a yellow stripe on the back of a rookie’s car to let everyone know there’s a newbie behind the wheel. Yellow stripes are also applied to the cars of non-rookie drivers if it is their first time at a track, letting fellow racers know that they may not be as experienced in a specific situation. The yellow-stripers with the most rookie wins are Jimmie Johnson and Tony Stewart, who each won three times in their first years.
