What must you do if you hear a siren while driving?

When you hear a siren while driving, it is important to yield the right of way and pull over to the right. This action allows emergency vehicles, such as police cars, ambulances, or fire trucks, to pass safely and quickly. Emergency responders often operate under urgent conditions, so giving them a clear path is not just a matter of courtesy, but also a legal requirement in many areas.

Pulling over to the right is the safest maneuver as it minimizes the risk of collisions with the emergency vehicle, which may be approaching at high speeds. Remaining calm and attentive is crucial, as you may need to assess your surroundings before making the move to ensure that you are not creating additional hazards.

The other options might suggest alternatives that could lead to confusion or unsafe situations. Ignoring the siren or only stopping when you see a police vehicle does not take into account the actions of other emergency services, nor does it prioritize the safety of all road users. Speeding up and merging could obstruct the emergency vehicle's path and significantly increase the risk of accidents.
