In recent years, the rules enfocement of KM number plate requirements have become laxed. However, the topic has been coming up more and more regarding the issues corner workers have idenfitying karts while on course (due to speed and size).

As such, this is a reminder of the official numbering rules regarding karts (Section 3.7.G - Vehicle Identification - Page 37):

Karts may use numbers and class letters of reduced size provided that the following conditions are met:

1. Numbers must be displayed on the front and rear in addition to both sides.

2. Class letters must be on both sides.

3. In no case may the numbers be smaller than 6” (15.25 cm) in height with 3/4" (2 cm) stroke, using a high-contrast color and background.
