What action is prohibited when approaching a fire scene?

Parking in the same block as a fire scene is prohibited because it can create significant safety hazards and impede emergency response efforts. Firefighters and emergency responders need clear access to the scene to perform their duties effectively, whether it's extinguishing a fire or providing medical assistance. If vehicles are parked too close, it can obstruct their movement and limit the space needed for firefighting equipment, hoses, and other emergency vehicles.

The other actions mentioned do not pose the same level of risk to emergency operations. For example, driving under the speed limit, while generally a prudent action, does not necessarily interfere with responders. Using emergency lights can be essential for warning other drivers and ensuring safe passage to the scene. Blocking access routes, while potentially problematic, is not the same as parking in the immediate area of a fire scene, which directly affects the capability of emergency personnel to respond effectively.
