SixTest: 100 km/h approval for vehicle combinations and buses
Under certain conditions, trailers may be authorised to be towed on motorways and expressways at a maximum permitted speed of 100 km/h. Similarly, under certain conditions, buses may travel at 100 km/h on motorways.
-
Basic information
Vehicles may be registered for a maximum speed of 100 km/h
- passenger cars with trailers
- multi-axle vehicles with a maximum authorised mass of up to 3.5 tonnes with a trailer, and
- buses
Requirements
The trailer must meet the technical requirements for the 100 km/h approval. Proof may be provided by a manufacturer’s certificate (confirmation of data in accordance with Section 20 of the Road Traffic Licensing Regulations (StVZO) in conjunction with Model 2d of the StVZO) or by a test report from an officially recognised inspection body.
In the case of buses, suitability for 100 km/h must be demonstrated by the vehicle description or an expert report from an officially recognised expert.
-
Procedure
If the trailer manufacturer has not provided or cannot issue a data confirmation for the trailer, or if the general operating permit for 100 km/h is to be determined retrospectively, the trailer must be presented to an officially recognised inspection body.
There, they will check whether your trailer meets the technical requirements for this speed. If this is the case, a certificate will be issued for the registration office.
The registration office will then make a corresponding entry in the trailer’s vehicle documents and issue the 100 km/h sticker. The sticker must then be affixed to the rear of the trailer.
The same applies to buses.
More information
- If the ZB II is held by a third party (e.g. a leasing company), it must be sent to the registration authority. The change can only be made once the document has been received by the authority. The ZB II is usually available at the registration authority 2 to 3 weeks after it has been requested. Once the process is complete, it is returned to the sender. The costs of storage and return are usually borne by the vehicle owner.
- The fixed connection between the towing vehicle and the trailer is no longer required.
- The towing vehicle is not inspected as a matter of course. The responsibility for ensuring compliance with the requirements – in particular the mass ratios – of Section 1 of the 9th Exemption Ordinance to the Road Traffic Regulations (StVO) lies with the owner or user of the vehicle/trailer combination. At the vehicle owner’s request, the officially recognised inspection organisations will also draw up a registration proposal for towing vehicles (specifying the permissible gross weights of the various trailer types) in accordance with Section 27 of the Road Traffic Licensing Regulations for field 22 of the vehicle documents regarding the 9th Exemption Ordinance to the StVO, which the registration authority will then incorporate into the vehicle documents.
