What this sign means
They are indicating an increased in the number of lanes ahead.
This is a road marking — an instruction or guide painted on the road surface itself. When you see it, work out what it changes about your driving — your speed, your position on the road, or what you are allowed to do next — and act early rather than late.
Where you will usually find it
Road markings are painted directly on the road surface. They divide lanes, control where you may stop, park, turn or overtake, and they work together with the upright signs around them. In the exam, treat a marking exactly as seriously as a metal sign — it carries the same legal weight.
