Final answer:
Vehicles should pull over to the right side of the road and stop when an emergency vehicle with flashing lights and an audible signal approaches.
Step-by-step explanation:
Upon the approach of an emergency vehicle displaying flashing lights and an audible signal, vehicles should pull over to the right side of the road and stop until the emergency vehicle passes by. This ensures that the emergency vehicle has a clear path to its destination and allows it to navigate the traffic safely.
It is important to mention that drivers should avoid running alongside or towards the ambulance as it can be dangerous and may delay the response time of emergency personnel.
