All,

To better facilitate smooth operating autocross heats this season, we will be enforcing the following rules regarding numbers:

1) Numbers need to be on both sides of the car
2) Numbers on the sides need to be no less than 8 inches in height
3) Numbers need to contrast with the background - white car can have dark numbers, but a black car can't use black tape
4) Window Chalk is not allowed because it is difficult to apply, produces inconsistent results, and is frequently unreadable
