What is the maximum speed for ambulances on dual carriageways?

The correct answer regarding the maximum speed for ambulances on dual carriageways is 60 mph. This speed limit is established to balance the need for rapid response times in emergency situations with the safety considerations for both the ambulance crew and other road users.

Ambulances, as emergency vehicles, are given certain exemptions from standard speed limits when responding to emergencies, such as when using lights and sirens. However, when they are not responding to a call, they are subject to the same speed limits as other vehicles. On dual carriageways, the speed limit for cars and vans is typically 70 mph, but for larger vehicles like ambulances, which may be more difficult to maneuver at higher speeds, the limit is set at 60 mph to ensure safety and control while providing timely assistance.

The other options reflect speed limits that do not apply within the context of a dual carriageway specifically for ambulances when not actively responding to an emergency.
