F1 Reaction Time Test

Five pairs of red lights illuminate from left to right, one per second. Once all five are on, the race director holds them for a random interval between 0.2 and 3 seconds and then extinguishes all of them at once. The race starts at lights out, not at any light coming on.

Moving before the lights go out, or reacting faster than 0.200s after they do. Transponders in the grid slot detect movement, and the FIA treats anything under two tenths as anticipation because human reaction cannot reliably be that quick.

Around 0.2 to 0.3 seconds from lights out. Drivers are not measurably faster than trained members of the public at pure reaction - what they add is a clutch and throttle launch executed perfectly in the same instant.

So the start cannot be counted. If the gap were fixed, every driver would time the launch rather than react to it, and the grid would effectively be a rolling start.

The anticipation is different. A plain test gives you one colour change; here you watch five lights build and then have to ignore the rhythm you just learned. Most people lose 20 to 50ms to that.

No. This measures the reaction half only. On a real grid the driver also has to release the clutch and feed the throttle without bogging down or spinning up, which is where most places are actually won and lost.

Reliable published figures cluster around 0.15 to 0.2 seconds, and anything below 0.2 is penalised, so the practical record is effectively pinned just above two tenths.

Yes, and it helps. Watching the last light rather than the whole bar, and keeping your finger already resting on the button, are worth more than any amount of raw training.
