F1 drivers react to the start lights in 0.2 to 0.3 seconds, close to the average person. See how the lights work, what a jump start is, and your percentile.
Published October 26, 2026
An F1 driver's reaction time at a race start is about 0.2 to 0.3 seconds, from the moment the five red lights go out to the moment the car starts to move. That is not much faster than you: the 70,940 results Human Benchmark grades its reaction time test against have a median of about 0.23 seconds, or 230 ms. On the HumanRank F1 Test, you react to the same five red lights.
So F1 drivers do not have superhuman reflexes. What sets them apart is getting it right on every start, with a clutch to release inside those 0.2 seconds and a penalty waiting if they guess.
Average under 200 ms over 3 starts and you beat about 3 players in 4.
Take the F1 Test
Formula 1 has shown a reaction time graphic on its broadcasts since the 2021 Turkish Grand Prix. Built with AWS, it counts from lights out until the car begins to move, so the figure includes the clutch biting and the tyres turning, not just the driver's reflex. That is how Valtteri Bottas could log 0.04 s at Suzuka in 2019: that number stopped at his first touch of the clutch paddle. Even then, he said it was "normally not a reaction time I can achieve."
Lab tests show a real but small edge. In a 2006 study in the British Journal of Sports Medicine, Heiner Baur and colleagues tested Porsche's 8 factory drivers, who raced at Le Mans, against 10 physically active people of the same age. In a go/no-go task, where you react to some lights and ignore others, the drivers answered in 331 ms on average, against 370 ms. The movement itself, about a tenth of a second, was no faster.
Under the FIA's sporting regulations, a race start is given by five red lights on the gantry above the grid. Once every car has stopped in its grid slot, the lights come on one by one, one second apart. Then all five go out together, and that is the start. No green light comes on.
How long the five lights stay on is not fixed. The time between the fifth light and lights out is left to the permanent starter, so it changes from one start to the next and cannot be counted.
Since 2026, there is also a step before the red lights: the grid light panels flash blue for 5 seconds as a pre-start warning, so drivers can build revs. The 2026 engines lost the MGU-H, the motor that kept the turbo spinning, so the turbo needs time to spool up before the launch. The FIA trialled the blue lights in pre-season testing in Bahrain, and the 2027 sporting regulations, published on October 19, 2026, write them into the start procedure.
From the moment the third red light comes on until the lights go out, every car must be stationary. A transponder in each car detects when it first moves from its grid slot. Move too soon and it is a jump start: the stewards can give a 5-second or 10-second penalty, a drive-through or a stop-and-go.
There is no minimum reaction time in F1. The only question is whether the car moved before the lights went out. At the 2017 Austrian Grand Prix, F1's timing data gave Bottas a 0.201 s reaction, and Sebastian Vettel questioned whether it was legal. The FIA cleared him: his car had made a very small movement while the lights were on, within the tolerance its system allows for clutch adjustments.
Not to a signal they did not see coming. Athletics draws the line at 0.1 seconds: in races timed with sensors in the starting blocks, World Athletics treats any reaction under 0.100 s after the gun as a false start, and one false start can mean instant disqualification. The rule rests on tests showing the brain cannot hear and process the gun any faster. At the 2022 World Championships, American hurdler Devon Allen was disqualified from the 110 m hurdles final for a reaction of 0.099 s.
Sprinters also have it easier than drivers: they react to a sound, and the brain processes sound faster than sight. F1 drivers react to lights, like you do on the F1 Test. A 0.04 s start means the driver began moving before the brain could even have registered the lights going out: an anticipation that happened to land on time.
Your F1 Test score is your average over 3 starts. The table compares it with the reaction time results Human Benchmark grades its own test against, the largest public dataset of simple visual reactions in a browser. The most common result there is 200 to 224 ms, where 1 result in 5 lands.
Percentiles from the 70,940 results Human Benchmark grades reaction time scores against, read on October 26, 2026. Lower is better. Human Benchmark averages 5 clicks on a screen that turns green, and an early click just restarts the try. The F1 Test averages 3 starts and counts a false start as 999 ms, so treat the comparison as approximate.

About 0.2 to 0.3 seconds at a race start, from the lights going out to the car moving, according to McLaren's performance coaches. The driver's reflex alone is shorter, since that figure includes the clutch biting and the car starting to roll.
There is no official ranking, because F1 does not publish a reaction time for every start. The most quoted figure is Valtteri Bottas's 0.04 s at the 2019 Japanese Grand Prix, measured to his first paddle movement, which he said he could not normally achieve. That is faster than anyone can react to a light, so it was well-timed anticipation.
The five red lights come on one second apart, so the fifth lights up 4 seconds after the first. They then go out after a delay chosen by the permanent starter, which changes from start to start so drivers cannot time it. Since 2026, the grid panels also flash blue for 5 seconds before the first red light.
Moving after the third red light comes on and before the lights go out. A transponder in each car detects its first movement, and the stewards can give a 5-second or 10-second penalty, a drive-through or a stop-and-go.
Yes. An average of 200 ms beats about 74% of the 70,940 results Human Benchmark grades its reaction time test against, whose median is about 230 ms. It is also inside the 0.2 to 0.3 seconds an F1 driver needs to get the car moving.
Since 2026, the grid panels flash blue for 5 seconds before the red lights as a pre-start warning. The 2026 engines have no MGU-H to keep the turbo spinning, so drivers need that time to build revs before the launch.
