When you hear a siren and/or see flashing emergency lights you should:

Answer: D — Pull over to the right side of the road

Seeing and hearing emergency lights and sirens means that an emergency vehicle is approaching, and it is important to get out of the way quickly. Pulling over to the right side of the road is the safest and most efficient way to do this, as it allows the emergency vehicle to pass on the left side. Moving to the left side of the road, as in option A, would block the emergency vehicle's path. Following the vehicle, as in option B, could lead to a dangerous situation if the emergency vehicle needs to make quick turns or stops. Continuing to drive, as in option C, could impede the emergency vehicle's progress and put yourself and others at risk. Therefore, pulling over to the right side of the road is the best and safest course of action when approaching an emergency vehicle.
