Proper use of the horn and headlight flashing helps prevent misunderstandings and accidents. Misuse can startle others or be illegal.
When to use the horn
- To warn of immediate danger
- To make yourself known when visibility is limited
- Short, controlled signals – avoid aggressive, long blasts
Headlight flashing
- Brief flash to warn or communicate
- Avoid dazzling; do not use high beam at close range
- Do not “teach lessons” with lights
Tips
- Combine with clear road positioning
- Avoid ambiguous signals; one clear message is best
- Be considerate of pedestrians and cyclists
