The objective of this paper was to determine the braking distance of a passenger vehicle when traveling at the speeds of 30, 50 and 70 km/h, on low friction surfaces (snow, deep snow) and also on asphalt. A number of tests were conducted on different surfaces. The vehicle was accelerated and then braked completely. Based on the braking distance values obtained by GPS, the adhesion coefficient was calculated for each surface for every velocity value tested.
