How to Use the F1 Reaction Time Test

This test copies a Formula 1 race start. The lights go out after a random delay, so you can't guess the moment. You have to react to it.

  1. Click to start. The five start lights begin to come on.
  2. Wait. All five lights stay on for a random moment.
  3. Click when they go out. Your reaction time shows in milliseconds.
  4. Repeat. Do five or more tries and look at your average.

What Is a Good F1 Reaction Time?

Most people land between 200 and 300 ms. Under 200 ms is very good. Race drivers usually react in about 150 to 250 ms at a real start, and they train hard for it.

How to React Faster

  • Watch the last light, not the whole row.
  • Rest your finger lightly on the button.
  • Play on a high refresh rate screen with a fast mouse.

How F1 Starts Work

In Formula 1, five red lights come on one by one, one second apart. After a random pause, all five go out together, and that's the signal to go. Drivers react in about 0.2 seconds. This test copies that sequence, so you can see how your reactions compare.

Tips for a Faster Start

  • Watch the lights, not the screen edge.
  • Rest your finger lightly on the button.
  • Don't guess. A jump start before the lights go out doesn't count.
  • Take your best of five, then your average.
  • Use a wired mouse and a high refresh rate screen for the lowest delay.

Why Your Time Might Be Slower Here

Your score includes your mouse, browser and screen delay. A 60 Hz screen can add up to 16 ms. Check your setup on the mouse latency test.

Frequently Asked Questions

Why was my click "too soon"?

You clicked before the lights went out. That is a jump start.

Does my monitor matter?

Yes. A 144 Hz+ screen shows the change sooner than a 60 Hz one.

Is there a classic version?

Yes, the reaction time test.
