Final answer:
The law requires you to not follow fire engines traveling to a fire closer than a safe distance.
Step-by-step explanation:
The law requires that you do not follow any fire engines traveling to a fire closer than a safe distance.
When emergency vehicles like fire engines are responding to a fire, they need clear access to the scene. Following too closely can impede their progress and put both the firefighters and other drivers at risk. It is important to give them enough space to maneuver and do their job effectively.
Therefore, running alongside the ambulance or running toward it would not be appropriate as it may obstruct their path or cause confusion. The best course of action is to stop moving and become stationary till it passes by.
