Braking Distance Calculator
How far does your car really take to stop? Enter speed, reaction time and road condition for an estimate of reaction, braking and total stopping distance.
Reaction
27.8m
Braking
56.2m
Total stop
84.0m
Educational estimate — real stopping distance depends on tyres, brakes, load and conditions.
How it's calculated
Reaction distance = speed × reaction time. Braking distance = speed² ÷ (2 × friction × g), with friction ≈ 0.7 dry, 0.4 wet, 0.2 snow. This is an educational estimate, not a safety guarantee.
