What should drivers do when they hear the siren of an emergency vehicle?

When drivers hear the siren of an emergency vehicle, they are required to move to the right side of the road. This action allows the emergency vehicle to pass quickly and safely, ensuring that it can reach its destination without delay. Moving to the right creates a clear path for the emergency responders who may be rushing to an urgent situation, such as an accident or medical emergency.

Stopping in their lanes is not the safest option as it can obstruct the emergency vehicle's path and potentially create hazardous situations. Ignoring the siren is dangerous and can prevent the emergency vehicle from effectively responding to emergencies. Speeding past the vehicle could lead to collisions or other accidents, compromising the safety of both the driver and emergency responders. Therefore, moving to the right is the most appropriate and safest response when encountering an emergency vehicle's siren.
