NASCAR Racing: Pit Road Exit - Tie?, pit road, two instruments

Question
Under a green flag condition, how does NASCAR score the car/driver if they exit pit road at the 'exact' same time?  Has it ever happened?

Answer
Hi Lori,

To the naked eye, a lot of ties have occured on exiting pit road.  But NASCAR has two tools it uses to break the ties.  First they have a super slow motion camera set straight across the line to visually determine who was first.  Secondly, they have a timing strip below the track that registers their cars as the cross the line. With these two instruments in use, there has never been a tie.
Hope i helped!
