Which signal is used to indicate special movement instructions for emergency vehicles at an intersection?
A flashing blue signal is used for emergency vehicles
Ordinary intersection signals use red, amber and green for stopping, caution and go for general traffic.
A separate colour is reserved so responders can be given special movement instructions distinct from normal traffic phases.
A flashing blue signal is the one associated with emergency vehicles, marking their special right of movement at the intersection.
Flashing red and yellow are general stop and caution warnings, and green is the normal proceed phase, none reserved for emergency movement.
Hence, the answer is a flashing blue signal is used for emergency vehicles.
