The F1 reaction time test copies a Formula 1 race start. Five red lights come on one per second, then all switch off after a random pause. Your score is the time from lights out to your tap. Drivers often react in about 0.2 seconds.
How a real F1 start works
At a Grand Prix the start gantry shows five pairs of red lights. They come on one column at a time, about a second apart. After all five are lit there is a short hold of random length, and then every light goes out at once. That is the signal to race.
Because the hold is random, drivers cannot time it. They must stay still and react to the lights going out. A car that moves before the lights go out gets a jump start penalty.
Why the lights out test is harder than it looks
The long build-up makes you tense. Many people twitch on the fifth light or flinch at a pause that feels long. That is why this test flags early taps as a jump start instead of letting you guess.
Reacting to lights switching off is also slightly different from reacting to a light turning on. Your eyes must notice a sudden loss of brightness across five lamps. Most visitors score a little slower here than on our classic test.
How you compare with F1 drivers
Published start data often shows driver reactions near 0.2 seconds, and the quickest starts dip lower. Drivers train this skill and use a real clutch and throttle, so the comparison is for fun. Beating 200 ms on a phone is still a great result.
How it works
- 01
Tap to start the sequence
Five red lights come on, one each second. Keep still and watch the gantry.
- 02
Go when every light goes out
The hold is random. Tapping while any light is red is a jump start.
- 03
Race three starts
Your average and best start appear, compared with F1 drivers and other players.

Frequently asked questions
What is a good F1 reaction time test score?
Under 250 ms is a strong score for most people on a phone or laptop. Around 200 ms puts you near typical F1 driver starts. Anything under 150 ms is exceptional and worth a second try to confirm.
How long do the F1 lights stay on before going out?
In a real race the lights stay on for a short random time after the fifth one lights up. The race director's system picks it so nobody can predict it. This simulator also uses a random hold each start.
What counts as a jump start in this test?
Any tap while a red light is still showing is a jump start. The attempt does not score, and you simply restart. Real drivers get a time penalty for the same mistake.
Do F1 drivers really react in 0.2 seconds?
Many recorded starts show driver reactions close to 0.2 seconds, with the best a little quicker. Clutch control and car launch then decide who gains places. Reaction alone does not win the start.
Why is my F1 test slower than the normal reaction test?
Lights switching off is a less obvious signal than a screen turning bright green. The build-up also makes people hesitant. A gap of 20 to 40 ms between the two tests is normal.
Can I train to get better F1 starts?
Yes. Short daily sessions, good sleep and a relaxed but ready posture help. Practise keeping still through the hold so you stop jumping the lights.
