Final answer:
When parking across from a fire station driveway, you typically need to keep at least 20 feet away, which amounts to about one or two car-lengths, but check local traffic laws for precise distances.
Step-by-step explanation:
When you park on the opposite side of the street from a fire station driveway, there is a specific distance you need to maintain. This rule is important to ensure that in case of an emergency, fire trucks can leave and enter the station without obstructions.
The exact distance may vary based on local laws, but a common rule of thumb is to keep at least 20 feet away from the driveway. This distance could be considered approximately one to two car-lengths, depending on the size of the vehicle. However, it's always best to refer to your local traffic regulations for the most accurate information.
