How I can identifier a Rookie Driver in the Nascar Series?

Yellow stripe painted on the bumper....."donuts" on the side of the car....crew chief stomping around and throwing things in the pits....several caution flags....multiple damage on their cars. LoL!

Just an opinion as always.

Yes, there are yellow stripes on the rear bumper of the car. The stripes are there to remind a veteran driver that the rookie driver is new to the series and has very little experience. If you are going to the Cup race, then you should see Joey Logano in the #20 and Scott Speed in the #82 with the stripes. The yellow stripes are also occasionally used for a driver that is racing at a certain track for the first time, such as Marcos Ambrose.

They will have yellow stripes on their back bumpers.If you are going to a Cup race,there will only be two rookies in the race:joey Logano in the Orange and white #20 Home Depot car and Scott Speed in the Blue and silver Red Bull #82 car.

The yellow stripe on the rear bumper.... and yes alot of the ways Jeff C described as well those were great,

Go Dale Jr & Hms in 2009

rookie stripes, which are long yellow stripes that go along the back bumper. They are taken off once the rookie year is over.

Kyle Busch now, he is almost always up front the end of the race to compete for the win, earlier this year I would have said Carl Edwards unfortunatly he has not run so well the past few races. Im sure he will be back on it soon though.

Yellow strip on the back bumper, it's a broken yellow line right on the back there.

Jeff hit the nail on the head! It makes me think of 'Days of Thunder' when the crew is eating ice cream in the pits... lol
