Behaviour in different situations


Merging when a motorway lane is terminating (zipping principle)

Application of the zipping principle (merging) is mandatory when a motorway lane is terminating. In heavy traffic, both lanes should be used until this is no longer possible. Ahead of the lane closure, allow a vehicle travelling on the terminating lane to merge into the continuing lane in front of you.


Merging when entering a motorway (zipping principle)

Traffic on the motorway has right of way over entering vehicles. Look for a large enough gap before merging and watch for vehicles in the blind spot. Use the entire acceleration lane in order to adapt your speed, and if traffic is moving slowly, enter the motorway in accordance with the zipping principle.


Behaviour at two-lane entrances

Here you should use the zipper system when entering the motorway. For this purpose, use the entire length of both lanes. The same rules apply as those for single-lane entrances.


Behaviour at exits

When leaving the motorway, change in good time to the normal lane (at latest when you see the second direction sign). Indicate early (200 metres before the exit) and only brake when in the deceleration lane.


Behaviour in a traffic jam

Every unnecessary lane change hampers traffic flow. Therefore you should stay in your lane as long as possible. The compulsory emergency lane must be kept open. Use all lanes until this is no longer possible. Observe the zipper principle when
changing lanes.


Behaviour in tunnels

  • Drive with dipped headlights, switch on the radio
  • Drive at a constant speed
  • Keep at a safe distance (at least 50 metres)
  • Never turn around

Behaviour in the event of a fire in a tunnel

  • Never turn around
  • Park at the side of the road as far away from the fire as possible
  • Switch on your hazard warning lights
  • Turn off the engine and leave your key in the ignition or place it on the centre console
  • Exit the tunnel as quickly as possible via the indicated escape route (observe the direction sign)
  • Use the SOS phone

Behaviour at roadwork sites

Maintain the indicated speed and keep a safe distance. In heavy traffic, car drivers should use both lanes and all available space. Observe the zipper principle when approaching a closed lane. Pay attention to the yellow-orange road markings. Maintain an adequate distance when approaching a roadwork site so that entering vehicles can merge safely.


Behaviour in the event of a breakdown

Park your vehicle in the emergency lane and turn on your hazard warning lights. Put on a safety vest and exit the vehicle, but never stand in the traffic lane. Where possible, use an SOS phone. Keep well away from the moving traffic. If possible, wait behind the crash barrier (be careful if you’re on a bridge). Place the warning triangle at least 100 metres behind the stationary vehicle.


Behaviour in the event of an accident

Involved drivers:

  • Pay attention to your own safety (warning lights, safety vest, warning triangle)
  • Protect the scene of accident
  • Alert the emergency services (phone nos. 112/117 or via an SOS phone)
  • Help other involved people
  • If the accident vehicles are drivable, park them in the emergency lane

First responders:

  • Pay attention to your own safety (warning lights, safety vest, warning triangle)
  • Alert the rescue services (phone nos. 112/117 or via an SOS phone)
  • Help involved people

Uninvolved drivers:

  • Drive with care and proceed as quickly as possible past the accident or breakdown site
