What must a driver do upon hearing a siren of an emergency vehicle?

When a driver hears a siren from an emergency vehicle, the appropriate action is to yield the right-of-way and pull over to the side of the road. This action allows the emergency vehicle, which may be responding to an urgent situation, to pass safely and quickly without interference. It is a crucial aspect of road safety and is mandated by traffic laws to ensure that emergency responders can reach their destinations without unnecessary delay.

Pulling over ensures that you are not obstructing the path of the emergency vehicle, thereby promoting the overall safety of the road for all users, including those in need of emergency services. Additionally, staying vigilant and aware of your surroundings while also complying with this rule assists in maintaining safe driving conditions for everyone involved.

The other options—accelerating to clear the road, continuing at the same speed, or stopping immediately without pulling over—do not facilitate the safe passage of the emergency vehicle and could potentially create hazardous situations for both the driver and emergency personnel.
