How should drivers react if they encounter emergency vehicles responding to a call?

When drivers encounter emergency vehicles responding to a call, they should pull over to the side of the road to allow the emergency vehicle to pass. This is essential for ensuring the safety of emergency responders and those they are attempting to assist. By pulling over, drivers create a clear path for the emergency vehicle, reducing the chances of an accident and allowing the emergency personnel to reach their destination as quickly as possible.

In many jurisdictions, laws require drivers to yield to emergency vehicles with flashing lights and sirens. This not only helps in the efficient and timely response to emergencies but is also a legal obligation in most areas. Failing to yield could impede critical assistance during emergencies, potentially putting lives at risk.

The other options do not adequately address the necessary actions. Sounding the horn or proceeding with caution without stopping could distract or confuse both the emergency responders and other drivers, and continuing to drive without yielding could result in dangerous situations or legal consequences. Thus, pulling over is the safest and most appropriate action for drivers in these situations.
