Transports that do not comply with the construction and operating regulations of the Road Traffic Licensing Regulations (StVZO) require a special permit in accordance with § 70 Para. 1 StVZO in order to participate in public road traffic.

Exemption permits for heavy goods and freight traffic according to § 70 StVZO and the permit according to § 29 StVO are always required together in the above-mentioned cases. If one of the permits is not available, the other is also invalid.

As a general rule, exceptions may only be approved if all reasonable possibilities for compliance with the regulations of the StVZO have been fully exhausted.

They may only be approved to the extent that is unavoidably necessary for the intended purpose (strict standard); no exemption may be granted for economic reasons alone.

An exemption may be granted if the vehicle/vehicle combination itself is too long/too wide/too high - see § 32 StVZO - protruding load (e.g. due to loading area extensions and/or extensions) and/or

if higher axle loads and/or total weights than legally permissible - see § 34 StVZO - are to be used and/or

if the driver's field of vision is impaired - see § 35 b StVZO.

The exemption permits must be obtained by the vehicle owner, carried on journeys and handed over to the responsible persons for inspection on request.

The exemption is usually limited to three months.
