Time Trials is the term for competition in which competitors vie for the fastest lap or elapsed time to complete a designated course. Time Trials competitors may share the track or course, but these events are not wheel-to-wheel competitions.

Within the Time Trials program, there are three primary formats:

1. Time Attack
"Time Attack" is the modern term which best described traditional Time Trials. This format means competing for the best lap on a closed course purpose built for performance driving or motorsports.

2. TrackSprint
TrackSprint is a format for competition on a specific section of a closed course purpose built for performance driving or motorsports. (E.g., a standing-start run from a specific point on track to a flying finish at a different point on track.) Though cars may share the course, there should be enough space to avoid cars passing or running in close proximity to each other.

3. HillClimb
Hillclimb is a competition where one car at a time competes on a closed public road, typically with "climbing" elevation as a primary feature. Though cars may share the course, there should be enough space to avoid cars passing or running in close proximity to each other.
