Glossary
The width of a vehicle is its dimensions from its right side, to the left. On average, a passenger car is about 1.9 metres wide if you count the rear-view mirrors.
A vehicle driven on a public road may not be wider than 260 cm including the load, and the load may not extend a maximum of 20 cm on each side (regardless of the vehicle width). If the load is indivisible, such as a boat, the width may be up to 310 cm, provided that the combination is properly marked.
