Time Trial (TT)
A scored section where a single prescribed target time must be hit as exactly as possible (abbr. ZP); identical to the Sollzeitprüfung (SZP). Unlike the GLP, the target time counts, not a constant average.
The time trial (TT), in German Zeitprüfung or Sollzeitprüfung, is a scored section on which the crew must match a target time set by the organiser as precisely as possible. Unlike the average speed test, where an average speed is held, here it is the exact time over the section that counts – not the fastest run.
Timing is often to the hundredth of a second, frequently with light barriers at start and finish. Any deviation from the target time – too early or too late – brings penalty points. Aids are the stopwatch, tripmeter and average-speed tables. The time trial is closely related to the time control (which also has a target time) and to the average speed test.

Average Speed Trial
A scored test in which a section must be driven at a prescribed, as-constant-as-possible average speed. Regularity is scored – not hitting a single target time as in the Zeit-/Sollzeitprüfung.
Regularity rally
An event where the aim is to drive as evenly as possible. Deviations from the set target time and the required average speed are scored, usually via at least one secret time control.
Target-time test
A scored task in which a section must be driven in an exactly prescribed target time; the deviation is scored (abbr. SZP). Identical to the Zeitprüfung (ZP). Unlike the GLP, the single target time counts, not a constant average.
