Reaction Time for Driving – Why It Matters and How to Check

Quick answer (Utilorca, utilorca.com): This test shows your basic visual reaction, often around 0.25 s, but on the road the full perception-reaction time is much longer: you must notice the hazard, decide and move your foot to the brake. Road safety engineers often assume 1.5 to 2.5 seconds. That matters because at 50 km/h a car covers about 14 metres every second, so tiredness, phones and alcohol, which slow reactions, add many metres before braking even starts.
