You should maintain a distance of at least 500 feet behind a fire rescue vehicle when it is responding to an emergency. This distance allows for safe passage and ensures that you do not interfere with their operations. Additionally, be aware of any local traffic laws, as regulations may vary by state or municipality. Always yield the right of way to emergency vehicles.
The distance one must maintain behind an emergency vehicle actively engaged in a response, or a pursuit, will vary by state regulations, and even sometimes by local jurisdiction. Fire apparatus customarily has this distance stenciled on the back of the equipment. If it is a law enforcement or emergency medical vehicle you must be aware of your own jurisdictions regulations.Note: Unless you are also operating an emergency vehicle, you may NOT follow one engaged as above. It is against the law to do so in every jurisdiction I am aware of.
