F1 Reaction Time Test
Simulate the iconic Formula 1 race-start sequence. Five red lights illuminate one by one — the moment they go out, hit the button as fast as you can. Can you beat 200ms like a real F1 driver?
How It Works
The F1 reaction time test simulates the exact light sequence used at every Formula 1 race weekend. Five red lights illuminate one by one over roughly two seconds, then go out simultaneously after a random delay (between 0.2 and 3 seconds after the last light). The moment all lights go dark — that's your trigger. Click as fast as possible.
A typical F1 driver reacts in 180–220 ms. The average human reaction time is around 250–300 ms. Anything under 150 ms on this test is likely an anticipation (false start) — just like a jump-start penalty in real F1. Your best score is saved locally so you can track improvement over time.
Reaction time is trainable. Regular practice, good sleep, hydration, and minimising distractions can meaningfully improve your reflexes. Use this test as a daily benchmark.

Frequently Asked Questions
performance.now() which gives sub-millisecond timing resolution. The main variables are your monitor's refresh rate and hardware latency (screen + mouse/keyboard). Most setups add ~5–15 ms of unavoidable overhead, so treat your score as a relative benchmark rather than an absolute ground-truth time. Compare your own runs against each other!
