The Road Traffic Regulations (StVO) apply on the PTB premises; among other things, these regulations require drivers to show consideration for one another on the roads.
The speed limit is 40 km/h.
A speed limit of 10 km/h applies in the entrance and exit areas.
As a sign of mutual consideration, vehicles must only be parked in the designated parking areas, and parking spaces for people with walking difficulties (or those with health conditions), as well as visitor and emergency services parking spaces, must be kept free exclusively for those entitled to use them.
