Billy Cart Racing Rules



TheseRules are being developed and could change at any time. It would pay to check with the race directors before building a Billy Cart to compete.

There are many other venues holding races in Australia as well. Most have a class for kids and their creations.

6.2

The driver must wear eye protection of some sort whilst driving. This can be either a helmet’s visor or safety goggles.

7.

No BS Rule

7.1

The no BS rule is left to be vague for the guy that is looking for a loophole in the rules to gain an unfair advantage. Just because every possibility was not covered does not mean you should go on and do it. We reserve the right to DQ your car for any reason. We will be fair, Veteran drivers keep in mind your long tenure does not confer any special treatment, everyone is subject to the rules, please follow them.
