Step-by-step explanation:
The question you're asking relates to traffic laws regarding emergency vehicles. According to most traffic regulations, you must not follow a fire truck responding to a fire alarm closer than 500 feet.
This law ensures that emergency vehicles have the necessary space to operate safely and quickly respond to emergencies without interference from other vehicles on the road.
