When parked at an incident scene, what should you do with forward-facing lights?

• A. Keep all lights on to warn drivers.
• B. Turn off all forward facing lights.
• C. Only turn off blue emergency lights.
• D. Turn on hazard lights only.

Answer: (B)

When parked at an incident site, minimizing forward illumination helps prevent blinding or confusing drivers who are approaching. Forward-facing lights can create glare or give the impression that a moving emergency vehicle is coming, which can increase risk to responders and motorists. Turning off those lights reduces this risk while still allowing you to use other safety measures to alert traffic.

That’s why turning off all forward-facing lights is the best practice. Keeping all lights on would cause glare and distraction for drivers. Turning off only the blue emergency lights doesn’t address the glare from the other forward-facing lights. Relying on hazard lights alone may not provide enough visibility or clear indication of the scene to approaching traffic.
