What must you do when leaving the edge of the roadway?

When leaving the edge of the roadway, it is crucial to ensure safety for both yourself and other road users. According to German traffic rules, it is important to check for traffic from behind to avoid colliding with vehicles that may be approaching. This is critical because changing lanes or re-entering the roadway requires awareness of the traffic situation behind you.

Additionally, switching on your direction indicator is necessary to signal your intentions to other drivers. This warning allows them to anticipate your movement, which helps prevent accidents.

Relying solely on the rear-view mirror, as suggested in the third option, is not sufficient. While it’s important to check the mirror, it does not provide a complete picture of the surroundings. Therefore, a combination of checking for traffic from behind and using your direction indicator is vital for making safe maneuvers when leaving the roadway.
