When may you use the horn?

What does this rule or driving tip mean? Signals can draw a road user’s attention, but they can also cause alarm and noise nuisance. That is why they are intended for avoiding imminent danger. How to apply this safely Brake and create space before considering a signal. Do not use the horn as a punishment or as a greeting. Take cyclists, horses, and pedestrians into account, as they may startle easily. Driving lesson and exam tip A signal is never a substitute for slowing down or swerving. First solve the danger with your driving. Remember: Only honk when it is necessary to prevent immediate danger. View the source: RVV 1990, article 28.
