Warning signs
Traffic queues likely on road ahead
What it means
The "Queues likely" plate that goes under the queuing-traffic triangle, used where traffic backs up somewhere you would never see it coming, such as round a bend or over the brow of a hill. Ease off the accelerator early, spread your braking out, and check your mirror so the driver behind gets warning too.
