What should you do when you hear a horn from behind you?

Hearing a horn from behind indicates that another driver may be trying to alert you to their presence or signal a potential hazard. Checking your rearview mirror allows you to assess the situation and understand how close the vehicle is and whether it requires you to yield or change your current driving behavior. This proactive approach helps ensure safety by allowing you to make informed decisions. Being prepared to yield if necessary is crucial, as it could prevent an accident by giving the other driver the space they need to pass safely.

Ignoring the sound may put you at risk by failing to recognize a potentially urgent situation, while accelerating or changing lanes without awareness could lead to dangerous interactions with other vehicles, increasing the likelihood of a collision. Therefore, the most responsible action involves checking your rearview mirror and being prepared to yield if needed.
