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.

National Billycart Class Regulations - Draft

National Billycart Class Technical Regulations

These are based on a general specification of vehicles raced throughout the country. Safety is the main priority in these regulations, along with ensuring that a spirit of ingenuity is retained to allow designers as much freedom as possible.


General Configuration


Vehicles must be single seat machines


Vehicles must have a minimum of four wheels arranged in a front and rear pair


Drivers must be seated in the vehicle in a traditional feet first driving position


Dimensions and Weights


Maximum length



Maximum width



Minimum ground clearance

20mm (although more may be recommended at some venues due to surface irregularities)


Minimum track



Maximum racing weight


The maximum racing weight refers to the total weight of vehicle, driver and ballast, and will be weighed both before and at the completion of each vehicle’s run. Vehicles which will exceed 200kg with driver aboard may not run with any removable ballast and the vehicle must weigh in under 100kg




Brakes must operate on a minimum of two wheels


Brakes must operate on both wheels of a ‘pair’ – i.e. either both front or both rear wheels


Brakes must be of the calliper, disc, drum or scrub type


Any braking system that relies on contact with the ground is forbidden.


Wheels and tyres


Maximum wheel diameter 24”


Tyres must be pneumatic


Safety Equipment


Vehicles must be equipped with a triangulated rear rollbar and a front rollover structure forward of the steering wheel


No part of the driver may be above an imaginary line drawn from the top of the rear roll bar to the top of the front roll structure whilst in the normal driving position, with helmet and belts on


Vehicles require a minimum three point ‘lap-sash’ seatbelt although a four point seatbelt is recommended


Vehicles with enclosed cockpits must have an easily identifiable external release system that can be operated from outside the cockpit without the need for tools.


Driver Apparel


At all times whilst in the vehicle, the driver must wear full length clothing, enclosed shoes, gloves, and a helmet to minimum AS1698 standard


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


No BS Rule


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.
