What should you do if you see an emergency vehicle with flashing lights?

Answer: B — Pull over to the side and stop

When you see an emergency vehicle with flashing lights, the appropriate and correct response is to pull over to the side of the road and stop. This action is crucial for several reasons. Firstly, it ensures that the emergency vehicle can pass through traffic safely and quickly, as they may be responding to a critical situation where every second counts. Stopping also helps to clear the road for the emergency responders, allowing them full access to the area where they are needed. It is essential for all drivers to be aware of and comply with this law to help maintain safety on the roads and assist emergency services in carrying out their duties without unnecessary delays. Continuing to drive normally, trying to speed up, or using your horn can impede the emergency vehicle and create dangerous situations for both the responders and other road users. Thus, the best practice is indeed to pull over and stop until the emergency vehicle has passed.
