What is the maximum dimension

§ 32 StVZO (dimensions of vehicles and vehicle combinations)

The regulations on permissible dimensions of motor vehicles in Germany

In Germany, the width of the lane usually varies between 2.75 m and 3.75 m. Accordingly, the Road Traffic Licensing Regulations (StVZO) also specify guidelines that regulate the maximum width and other vehicle dimensions. The height - particularly important for bridges and tunnels - and length of motor vehicles are also regulated. All provisions and regulations for the individual vehicle groups can be found in Section 32 StVZO.

The width of the lanes is fixed in Germany. Accordingly, a vehicle may only have a permissible total width of 2.55 m exceed. For Passenger cars a maximum permissible width of 2.5 m.

At agricultural and forestry vehicles A permissible width of up to three meters applies, as road use is only intended in exceptional cases and under strict conditions.

The width of the lane can vary widely within construction sites on motorways. The left lane is then often only 2.5 m wide, so that only vehicles with a width of up to two meters are allowed to use it.

Trucks must always be on the right lane drive that with a width between 3 m and 3.25 m can also be driven on by wider vehicles.

Vehicles and teams on German roads with a length over 18.75 m are not allowed.
