Shape and colour

Triangle with a red rim and black cars in a line: warning of a queue.

Where the sign stands

Outside the built-up area 100–150 m before the stretch where queues form, on the right; often as a temporary sign or on a matrix sign.

What the exam asks about this sign

The exam asks what to do at a queue warning: slow down, increase distance and when traffic is at a standstill switch on the hazard lights to warn traffic behind. Trap: candidates think they may use the hard shoulder in a queue; only when a sign or matrix sign says so.

No practice question uses this sign; the sections below explain it.
