In 1990 a member of Bill Elliott's crew lost his life on pit road. This was blamed on excessive speed on pit road so good ole Nascar set down and drafted a new set of rules for the following year.
So pit road 101 for crews and fans was initiated.
Enter the use of two pace cars,one was used on the track and the other was used on pit road to control the speed.
Now when you pitted under the yellow you could not change tires,only gas and repairs could be made.
Now comes the yellow and blue sticker theme.You can only change tires during the green flag and on either on even or odd numbered laps,thats where where the yellow and blue stickers come in.
This didnt last very long,now can you tell how this impacted the rest of the year and what followed ???
