How to use the F1 reaction test
Start the sequence
Click the box or press Space anywhere on the page.
Watch the lights
Five red lights come on one by one, one second apart, then hold for a random moment.
React at lights out
The instant every light goes out, click, tap, or press Space or Enter.
Don't jump the start
Reacting before lights out, or within 0.100 s of it, counts as a jump start.

What is a good F1 reaction time?
A good F1 start reaction time is under 0.250 seconds. F1 drivers are often quoted at about 0.200 s, while most people react in 0.250 to 0.300 s. A time under 0.200 s puts you on pole position here.

What is the launch gap?
The launch gap shows what your reaction time is worth on track. It compares where you'd be with a car that reacted in 0.200 s, at the moment that car reaches 100 km/h. It's a simple estimate, assuming both cars go from 0 to 100 km/h in 2.6 s at an even pace.
| Your reaction | Launch gap at 100 km/h | In car lengths (5.5 m) |
|---|---|---|
| 0.150 s | 1.4 m ahead | 0.3 |
| 0.200 s | Level | 0 |
| 0.250 s | 1.4 m behind | 0.3 |
| 0.300 s | 2.7 m behind | 0.5 |
| 0.400 s | 5.3 m behind | 1.0 |
How to get a faster start
Watch the lights, don't count. The hold is random, so timing a rhythm after the fifth light leads to jump starts.
Rest your finger on the button. Keep it lightly on the mouse button or Space bar, ready to press.
Use a low-lag setup. A wired mouse or keyboard reacts sooner than Bluetooth or a touchscreen.
Play on a fast screen. A 144 Hz or faster monitor shows lights out sooner than a 60 Hz screen.
Warm up. Do a few starts before going for your best time.
Frequently asked questions
What is an F1 reaction test?
An F1 reaction test copies the start of a Formula 1 race: five red lights come on one by one, then all go out after a random pause. Your reaction time is how quickly you respond to lights out, shown in seconds to three decimal places.
How do F1 start lights work?
When all cars are in position on the starting grid, Race Control starts an automatic sequence. Five red lights on the start gantry come on at one-second intervals. After a short pause of random length, every light goes out at once, and that is the signal to start the race.
Why is there no green light at the start of an F1 race?
Because lights out is the signal to go. Green lights are shown earlier in the start procedure, before the formation lap, and yellow lights warn of a delayed start. The race itself begins when the five red lights go out, with no green light.
How long is the random delay before lights out?
In Formula 1, the pause after the fifth red light is chosen at random by the start system and lasts no more than a few seconds, so drivers can't predict it. In this test, the lights hold for a random 0.5 to 3.0 seconds before going out.
What counts as a jump start?
In a real F1 race, a jump start is when a car moves before the lights go out, and it's punished with a penalty. In this test, any click or key press before lights out is a jump start, and so is a reaction under 0.100 s, which is too fast to be a real reaction.
How fast do F1 drivers react at the start?
F1 drivers are commonly quoted as reacting in about 0.2 seconds, slightly faster than the 0.25 to 0.30 seconds most people manage. Lots of practice, full focus and knowing the start sequence well help them get close to that limit.
What is the difference between the F1 reaction test and a reaction time test?
The F1 test counts down with five lights before a random hold, which tempts you to guess, so it tests patience as well as speed. The Reaction Time Test gives no countdown, just a random wait, and shows your reaction in server ticks.
Does the F1 reaction test work on phones?
Yes. Tap the box to start and tap again at lights out. Touchscreens often add a little delay compared with a mouse or keyboard, so compare phone times with other phone times.
