Warning signals
Where the safety of traffic so requires, the driver must warn other road users. Unnecessary and excessive warning signals must be avoided. Call signals with the warning device are prohibited
The driver must behave in such a way that acoustic warning signals or light signals (even during the day) are not necessary, if possible. He may give such signals only where the safety of the traffic requires it
The driver must give acoustic warning signals when children are not paying attention to the traffic in the area of the road and before unclear, narrow curves outside towns
After dark, only light signals may be given. Acoustic warning signals are only permitted in emergencies
