Formula One start reaction

Formula One start reaction
150 ms–300 ms
Reaction — a decision, via the brain

The lights-out reaction is a visual one, so it cannot beat the roughly 200-millisecond visual floor, and the times that get quoted as remarkable are usually the clutch release rather than the reaction. The start procedure deliberately randomises the hold before lights out precisely so drivers cannot anticipate. Anything faster than about 0.15 seconds gets scrutinised as a jump start, and cars are fitted with transponders that detect movement before the signal.

What it is

What is measured
Time from the five red lights going out to the car moving.

Why this is a reaction

A reaction is a decision: signal in, processing, movement out. The floor for a human is around 150 milliseconds, and anything measured below about 100 ms is anticipation rather than response.

Common questions

How long is formula one start reaction?
Typically 200 ms, with a real range of 150 ms to 300 ms. Time from the five red lights going out to the car moving.
Is that a reflex or a reaction?
Reaction — a decision, via the brain. A reaction is a decision: signal in, processing, movement out. The floor for a human is around 150 milliseconds, and anything measured below about 100 ms is anticipation rather than response.
