You can quickly become annoyed in traffic. But honking is not allowed in every situation. If you press the horn too quickly, you may be committing an offence.
It doesn’t matter whether it’s a horn or headlight flasher: They are only allowed on these occasions
Flashing the headlights without a good reason always costs 10 euros – whether with or without annoyance. However, if you only behave prudently and only want to warn other road users of a dangerous situation, you don’t have to answer for it either. However, one should not try to educate others with these means. Because this is definitely not allowed.
The situation is different with the sound signals that electric cars emit. Up to a speed of up to 20 km/h or when reversing, these warnings are even expressly permitted by law to avoid danger.
However, anyone who installs a different horn in their vehicle than the one provided by the vehicle manufacturer should bear in mind that multi-tone horns and horns that are too loud are not permitted. When measured at a distance of 7 m, their volume must under no circumstances exceed the limit of 105 dB(A).
