Are you allowed to ignore a posted speed limit when responding with lights and siren?

• A. Yes, you may ignore speed limits with lights and siren.
• B. Yes, you may exceed the limit if there is no traffic.
• C. No; comply with traffic laws unless department policy authorizes deviations; use caution and dispatch.
• D. Only if your siren is on.

Answer: (C)

Even in emergencies, traffic laws still apply unless your department policy explicitly authorizes deviations. The lights and siren signal urgency and help clear a path, but they don’t automatically allow you to speed or violate rules. You should adhere to posted speed limits and standard driving rules while you assess conditions and prioritize safety. If your agency allows speeding or other deviations, it must be documented in policy and coordinated with dispatch; otherwise, drive with caution, adjusting for road, weather, and traffic. The siren alone does not grant exemption from laws, and unauthorised speeding increases the risk to you, your crew, and the public.
