Audit and expert opinion
If you want to set off on holiday with a caravan or trailer, you should get a 100 km/h speed limit permit for your vehicle combination. This allows you to drive at speeds of up to 100 km/h on motorways and motorways in Germany instead of the usual 80 km/h.

Under normal circumstances, vehicle combinations (i.e. car plus caravan or trailer) may only travel at 80 km/h on motorways and motorways in accordance with Section 3 of the StVO. According to the 9th exemption regulation to the StVO, it is possible to increase the maximum speed on motorways and motorways to 100 km/h for cars with trailers and for multi-lane motor vehicles with a maximum permissible mass of up to 3.5 t with trailers. A caravan or car trailer with a speed limit of 100 km/h can therefore travel at 100 km/h with various towing vehicles.
The technical requirements are:
In addition, certain mass ratios between the trailer and towing vehicle must be observed. Calculating the legally permissible total mass of the trailer is a little complicated:
The maximum permissible gross weight (GVW) of a trailer that is to be operated at 100km/h can be calculated as follows:
Unladen weight of the towing vehicle * factor X -> maximum GVW of the trailer.
The factor X by which the unladen weight is to be multiplied can be found in the following table:
The values marked with "*" may be utilised if:
is equipped.
| without hydraulic shock absorbers | with brake and hydraulic shock absorbers | |
| Caravans | Other trailers | |
| 0,3 | 0.8 or 1.0* | 1.1 or 1.2* |

In principle, you may only drive a maximum of 50 km/h with a trailer in urban areas and 80 km/h outside urban areas. If the trailer has a 100 km/h registration, you may drive at 100 km/h on the motorway and on motorways.
A 100 km/h sticker on the caravan or trailer does not automatically mean that you are actually authorised to drive at this speed with your vehicle combination. As the person driving the vehicle, you are responsible for ensuring that, in addition to the technical requirements of the caravan or car trailer, the following technical requirements of the towing vehicle are also met:
Tip: Before every journey, regularly check the age of the trailer tyres and that the technical requirements of the towing vehicle are met (ABV, drawbar load, total weight, etc.).
Before testing, make sure that all conditions for the 100 rule are met.
With a category B driving licence you may:
