This vehicle stopping distance reference table shows the total stopping distance for a range of speed values, assuming a reaction time of 1.5 seconds and a friction coefficient of 0.7. Every figure is computed with the same engine that powers our Vehicle Stopping Distance Calculator, so the numbers are exact.
| Speed | Total stopping distance | Braking distance |
|---|---|---|
| 15 km/h | 7.51 | 1.26 |
| 30 km/h | 17.56 | 5.06 |
| 45 km/h | 30.13 | 11.38 |
| 60 km/h | 45.23 | 20.23 |
| 90 km/h | 83.01 | 45.51 |
| 120 km/h | 130.90 | 80.90 |
| 180 km/h | 257.03 | 182.03 |
| 300 km/h | 630.64 | 505.64 |
| 420 km/h | 1,166.05 | 991.05 |
| 600 km/h | 2,272.56 | 2,022.56 |
How to use this table
Find the row closest to your speed and read across to the total stopping distance. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Vehicle Stopping Distance Calculator for a precise answer.
Need a value that is not in the table? — the Vehicle Stopping Distance Calculator does it instantly, for free, with the formula and a worked example built in.
