You must not follow any emergency vehicle that has its siren or lights operating within:

When an emergency vehicle is responding to an incident with its sirens or lights activated, it is essential for other road users to maintain a safe distance. In New Brunswick, the law stipulates that you must not follow such emergency vehicles within a distance of 150 metres. This distance is important because it allows emergency responders to operate without interference, ensuring that they can reach the scene of an emergency swiftly and safely.

Maintaining this safe following distance also protects other road users, as emergency vehicles may need to stop suddenly or maneuver in ways that are not typical of regular traffic. Keeping a separation of 150 metres helps to prevent potential collisions and allows for any necessary traffic control measures that emergency personnel may need to implement while responding to an emergency situation.
