How should you react to an emergency vehicle with flashing lights?

Answer: B — Pull over to the right side of the road and stop until it has passed

When you encounter an emergency vehicle with flashing lights, the appropriate action is to pull over to the right side of the road and stop until the vehicle has passed. This response is critical for ensuring the safety of both the emergency personnel and other road users. By stopping and yielding the right-of-way, you are allowing the emergency vehicle to navigate through traffic quickly and efficiently, which is essential in urgent situations where every second counts, such as medical emergencies or fire rescues. This response also reflects the law in many jurisdictions, including Arkansas, which requires drivers to move over for emergency vehicles. Failing to do so can result in penalties and fines. Stopping also prevents potential accidents that could occur if drivers attempted to weave through traffic or continue driving as if there were no emergency vehicle present.
