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

When leaving the edge of the roadway, it is important to ensure the maneuver is safe for all road users. First, you must check for traffic from behind to avoid cutting off other vehicles or causing a danger. This means looking over your shoulder and using mirrors to get a complete view. Second, you must switch on your direction indicator to signal your intention clearly to others. This alerts drivers and pedestrians about your planned move. Simply looking into the rear-view mirror is not sufficient because it does not provide a complete view of all areas, especially blind spots. Following these steps helps prevent accidents and ensures smooth traffic flow.
