Which of the following is true regarding the operation of fire apparatus on highways?

The operation of fire apparatus on highways is governed by specific traffic laws and regulations that prioritize safety while ensuring an effective response to emergencies. When a fire apparatus is not responding to an emergency, it is required to follow all standard traffic laws. This includes obeying traffic signals, speed limits, and other road regulations. However, when responding to an emergency, certain privileges may apply, allowing the apparatus to operate differently from regular vehicles.

The option stating that they should follow all traffic laws unless responding highlights the importance of adhering to normal traffic regulations for safety during non-emergency conditions. This understanding is crucial, as it ensures that emergency vehicles do not contribute to accidents or unsafe situations when they are not in active response mode.

In contrast, using sirens is not always mandatory, and fire apparatus does not have the right of way at all times. While they can proceed through red lights when emergency conditions warrant it, that action must still be taken with caution and in accordance with traffic laws applicable during such responses.
