Final answer:
When an emergency vehicle is stopped on the right side of a multi-lane road, drivers should stop moving and become stationary until the emergency vehicle passes by.
Step-by-step explanation:
When an emergency vehicle such as a police car or ambulance is stopped on the right side of a multi-lane road, it is important for other drivers to be aware and take appropriate action. The proper response is to stop moving and become stationary until the emergency vehicle passes by. This allows the emergency vehicle to have a clear path and reach its destination quickly. Running toward or alongside the ambulance is not safe or necessary.
