Traffic rules: Do I have to signal when turning is mandatory?. As of: February 5, 2024, 9:30 a.m CommentsPressSplit You also have to Signal if the traffic sign directs cars in one direction.
The road traffic regulations require this for safety reasons. If you want to drive past an obstacle on the road, you must indicate this by flashing. The same applies to overtaking, for example on the motorway. Before pulling out, before leaving the existing lane, and before you cut back in and out of traffic.
