Final answer:
The correct distance to maintain when parking near a fire station's driveway entrance is 5 meters unless local regulations state otherwise. This restriction is to allow unimpeded access for emergency vehicles.
Step-by-step explanation:
It is illegal to park within 5 meters of a driveway entrance to a fire station, unless otherwise posted. This law ensures that fire trucks have unobstructed access in and out of the fire station during emergencies. Regulations regarding parking near fire stations can vary by jurisdiction, so it is important for drivers to pay attention to local parking laws and signs that may indicate specific restrictions in that area.
