Solo Vehicle Identification Rules

Competitors are responsible for both sides of their competition car being labeled with legible Numbers and Class letters per the SCCA Solo Rulebook.  It is encouraged to use a number between 1 and 99.  It is also encouraged that the second driver of a two-driver car uses the first driver’s number plus 100.

Example: Driver one is #9, then driver two is #109. No number above 199 is allowed.

Penalty for not changing numbers between driver’s runs will result in a DNF for that run.  

Proper identification of your car will help us tremendously in making sure the event runs smoothly.

Car Numbers: must be min. 8″ high with a 1.25″ stroke.
Car Class: must be min. 4″ high with a .75″ stroke and between 25%-75% of the height of the numbers

  • Letters must be in upper-case abbreviated form rather than spelled out. (example: CSPL instead of C Street Prepared Ladies)
  • All vehicles must display numbers and classes on both sides, which must be readable by timing & scoring, course and grid workers at all times.
  • Letters and numbers must be the same typeface and color, and this color must provide adequate contrast to the background.
  • Numbers and class letters must be on a body panel, not on windows
