It is intended that Safety Level 3 be similar to that of SCCA Road Racing. Vehicles of motorsports-specific construction are required to meet these specifications. For National Time Trial Events, vehicles prepared beyond Max Category Rules and competing on tires without DOT-Approval must meet Safety Level 3 Standards.

All Safety Level 3 vehicles must meet the requirements of Safety Levels 1 and 2, plus the inclusion of a roll cage compliant with specifications listed here. A roll cage consists of the main hoop, front hoop, side protection, and braces as specified in these Rules.

These specifications apply to all vehicles other than those issued an SCCA Logbook before 1/1/19. Cars issued an SCCA Logbook before 1/1/19 may continue to compete with the previously approved rollover structure or comply with the following specifications.

Please see SCCA General Competition Rules section 9.4 for diagrams and illustrations.
