2021 GTA Rules and Regulations
Vehicle Technical & Safety Regulations
Vehicles entering into any Global Time Attack (GTA) event must adhere to the regulations of this series as defined within this document; these regulations have been loosely based on universally recognized Time Attack rule packages of various series found around the globe. Regulations are formulated to ensure that all vehicles are properly prepared to a high standard and ensure safety compliance with the series requirements. All points listed will be strictly policed and checked, prior to the starting of each competition and any vehicle failing to comply with these regulations will be excluded from the competition. The following regulations apply to all Global Time Attack Competitors with specific rules for each class listed separately. The following regulations also apply to all Global Time Attack, Super Lap Battle, and GTA sanctioned time attack competitions during 2021.
Any vehicles not conforming may be excluded from any and possibly all Global Time Attack events. If appropriate any/all parts of the regulations may be changed or modified on the Global Time Attack website www.globaltimeattack.com by the Global Time Attack staff, stewards and technical officials at any time. Any modifications to regulations made in this way will be clearly marked and reported in the rules section of the Global Time Attack website.
The GTA rules were drafted in accordance with the SCCA & Global Time Attack Track Safety Minimums. GTA manages vehicle safety inspection, and in most cases timing and scoring. Your vehicle(s) must meet the basic requirements of the SCCA GTA Safety Minimums, found at: SCCA GTA SM 2021. As the driver, it is your responsibility to ensure your vehicle will pass inspection. Contact us BEFORE an event should any questions arise. If you arrive and your vehicle is deemed unsafe, it will not be allowed to run. GTA competing vehicles must pass GTA Tech. No exceptions!
If you are unsure if your vehicle meets the regulation requirements, it is your responsibility to clarify any/all areas or points prior to an event (or of equal importance, before tearing into your car with a Sawzall). Please address any technical questions to firstname.lastname@example.org.

Only one exception of this type will be allowed, if the competitor returns without valid safety requirements at a subsequent event, he/she will not be allowed to compete. If the discrepancy is deemed intentional under classing to avoid safety requirements, the competitor will be disqualified and will not be allowed to compete.

The competitor in question will still be inspected and disqualified if found to be illegal.

The competitor can choose to correct the issue and continue in their original class or be bumped to a class that the vehicle is legal in.
