STOPPING DISTANCE

City speed

Highway speed

Road surface

While calculating distances, the used formula features a reaction time of one second (1 s) and the mean deceleration on dry road surface is 9 m/s², on wet road surface 6 m/s², on snow-covered road surface 3 m/s² and on icy road surface 1.5 m/s².

The stopping distances and times have been calculated mathematically. In reality, there may be significant variation due to different vehicle structures. The distances have been approximated into the closest full metre.

This application was designed and developed for Liikenneturva by Taikalehto.
