In emergency cases, towing does not require a permit. A freeway must be left by the towing unit at the next junction. Driving onto the freeway is not permitted. An exceptional permit is required for towing via the freeway. It can be applied for in particular by companies that specialize in towing and have suitable emergency vehicles available for this purpose.
Towing is performed when an inoperable vehicle is to be taken out of circulation or to the next suitable place of repair or storage. This is based on the concept of emergency assistance. A vehicle can no longer move under its own power due to an accident or a technical defect and is to be taken out of the public traffic area. In these emergency cases, towing does not require a permit. For safety reasons, the towing unit must leave the highway at the next junction (see § 15 a Road Traffic Regulations). If a vehicle comes to a standstill outside the freeway, it must not be driven onto the freeway.
A special permit, often referred to as a "towing permit", is required for cases where towing is to take place via the fre eway. It can be especially for commercial entrepreneurs who offer the guarantee of safe and professional towing, that is, they specialize in towing and have suitable emergency vehicles for this purpose.
The permanent exemption permit is issued for towing for up to 250 km of freeway, whereby the area of application is limited to Bavaria. It is to be limited to a maximum period of three years.
In special cases, an individual exemption permit can also be issued.
