The F1 Start Sequence

In real F1, five red lights illuminate one per second. When all five are lit, the race director can extinguish them at any random moment between 0.2s and 3s. Drivers must react the instant lights go out — not anticipate.

Real F1 Reaction Times

The fastest legal F1 reaction at a race start is around 150ms. Average reaction times at race starts sit between 180ms and 250ms. Below 100ms is considered a jump start and triggers a penalty sensor.

False Start Penalty

In F1, a jump start detected by front-axle sensors earns a drive-through or 10-second stop-go penalty. In this test, clicking before lights-out adds a 500ms penalty to your result.

Train Your Reaction

Regular reaction practice can reduce response time by 20–50ms by shortening the cognitive processing stage. The physical nerve impulse speed (~70m/s) is fixed; the mental decision step is trainable.

Frequently Asked Questions

Real F1 drivers react in 150–250ms at race starts. Under 200ms is excellent for a regular person. 200–300ms is average. Above 400ms is slow by racing standards, though perfectly normal for most people.
A jump start occurs when a driver moves before the lights go out. FIA sensors measure front-axle load. Any movement before lights-out triggers a drive-through or 10-second stop-go penalty. This test applies a 500ms penalty to simulate the cost.
The randomised time between the fifth light illuminating and lights-out prevents drivers from anticipating the signal. FIA regulations mandate this randomisation. Use "Random Delay" mode in this test for the most authentic simulation.
Each of the five lights illuminates at roughly one-second intervals. The time between the fifth light and lights-out is random, typically between 0.2 and 3 seconds, to prevent anticipatory starts.
Yes. Regular practice reduces cognitive processing time — the mental decision step — by 20–50ms. The physical nerve conduction speed (~70m/s) is fixed at birth. Daily short sessions of 5–10 minutes produce measurable improvement over 4–6 weeks.
