Helmets are Required
All participants are required to wear a helmet for the derby, and there are no exceptions. Our first priority is that all of our participants are safe. Helmet checks will be performed at registration and are a prerequisite for participation. Bicycle, motorcycle, or football helmets are acceptable.
Steering Limitation is Required
There are no turns on the track at the derby, so there is only a need for about 5 degrees of steering capability. Oversteering can cause a vehicle to overturn or leave the track which can cause a safety issues for both spectators and participants. Steering checks will be performed at registration and are a prerequisite for participation.
Braking Capability is Required
It is recommended that a pedal brake is used, but other options for braking are allowed. It's also recommended that light materials are used so the brake is able to easily attain stopping power. Braking capabilities are inspected at registration and are a prerequisite for participation.
