===Safety===
The majority of the regulations pertain to safety. Cars must have two steel [[roll hoop]]s of designated thickness and alloy, regardless of the composition of the rest of the chassis. There must be an [[impact attenuator]] in the nose, and impact testing data on this attenuator must be submitted prior to competing. Cars must also have two hydraulic brake circuits, full five-point racing harnesses, and must meet geometric templates for driver location in the cockpit for all drivers competing. Tilt-tests ensure that no fluids will spill from the car under heavy cornering, and there must be no line-of-sight between the driver and fuel, coolant, or oil lines. Electric vehicles are also fitted with a ''Shutdown Circuit'', which is the physical electrical path the current takes that closes the main contactors of the vehicle. All safety buttons, switches, and circuits are part of the Shutdown Circuit such that removing any should make it physically impossible for high voltage to be present outside the accumulator.
