Try the F1 lights-out challenge
Watch the red lights build from left to right. Once the whole bar is red, keep waiting. Your moment is when every light goes out. This free F1 reaction test turns that Formula 1 start signal into a five-round game you can play with a mouse, touchscreen or Space key.
Can you beat your last average?
One quick round feels good. Five quick rounds are harder. Play a session, note your average, then try again with the same controls. Aim to lower that number without jumping the start.
Try five roundsKeep your hand ready.
Rest your finger on the mouse button or Space key, or keep it just above the screen. Watch the lights so you don’t have to find the button when they go out.
Wait instead of guessing.
If you keep jumping the start, take a few rounds to focus on waiting. Follow the lights rather than trying to predict when the pause will end.
Test stages
- Start and release. Click or tap the test area, or press Space. Release your input to begin the round.
- Watch the red lights. After one second in darkness, the five columns light up from left to right, one second apart. Each pair turns on together.
- Wait for lights out. After the fifth column lights up, there is a fresh random wait of 1–3 seconds. All ten lights then go dark at once.
- React, then continue. Press as soon as the lights go out. Read your time, then start the next round when you are ready.
Need another try?
Press too early? That’s a jump start. No response within five seconds of lights out? That’s a missed round. Neither counts toward your five scores. Try the round again when you’re ready.
Switch tabs or leave the window? The round stops, but your completed scores are kept.
Want a fresh start? Use Reset. On a phone, you’ll find it in the menu.
What does your F1 reaction time mean?
Lower numbers mean quicker responses. Your main score is the average of five valid rounds; your fastest time is your best single reaction. Jump starts and missed rounds are counted separately and don’t enter the average.
In this example, the five rounds average 230 ms, with a best of 210 ms. Select a bar to see how that round compares with the average.

What to look for across five rounds
Two sessions can share the same fastest time and still tell different stories. Imagine both include a 210 ms reaction, but one averages 230 ms and the other averages 280 ms. The first session has a quicker overall response, even though the personal best is identical. These are example scores, not targets you need to reach.
When reviewing your F1 reaction time, look at the slower rounds too. Was one unusually long, or were all five close together? On your next session, try to bring those slower responses closer to your best. Keep the jump-start count alongside the average so you can spot when a faster result comes with more early presses.
Turn it into a friendly race
The lights-out challenge works as a quick game with friends. Share one device and use the same control: everyone taps the screen, clicks the mouse or presses Space. Each player completes five valid rounds. Compare the averages first, then look at fastest rounds and jump starts together.
Let everyone play a practice session before comparing scores. Take turns, use Reset for a fresh group, and give each player the same number of sessions. Decide beforehand whether your F1 reaction test challenge uses the first session or the best of three. That keeps the game simple and gives everyone an equal number of chances.
F1 reaction test questions
What is a good F1 reaction time?
There isn’t one cutoff that makes a score good on every device. Use your first five-round average as a starting point, then aim for a lower average with no jump starts.
Can I compare my score with an F1 driver’s reaction time?
Not directly. F1 drivers respond to the lights while managing engine revs and clutch release. This game measures a click, tap or key press, so your score cannot tell you how you would compare on a race grid.
What is the F1 reaction test world record?
ReactionTests has no verified world record or global leaderboard. Scores from other sites use different setups and rules. Your fastest time here is your personal best for this test.
Does this F1 reaction test use sound?
No. Wait for all the red lights to go out; there is no beep. To test your response to sound, try the sound reaction time test linked below.
Why is the delay after all five columns light up random?
A fresh 1–3 second wait keeps each round from becoming a predictable countdown. The fifth column turning red still means wait. React when all ten lights go dark.
Is this F1 reaction test free, and where are my results saved?
Yes—no account or download needed. Open My stats to see completed F1 sessions saved in this browser. Clearing browser storage removes those records.
Why are my phone and computer scores different?
Screen refresh and input delays are part of your result. A phone tap and a mouse press can give different times, so use the same device and controls when tracking your progress.
