What it means

Rule 172: you must give way to traffic on the main road when you come out of a junction with broken white lines across the road. The Highway Code's road markings page adds that the same marking can be used at mini-roundabouts.

At quieter junctions the upright give way sign may not be there (Know your traffic signs), so the lines alone are enough to tell you to give way.

Where you see it

At the end of side roads where they meet a main road, at roundabouts, where you give way to traffic from the right, and at mini-roundabouts.

A common mistake

Looking only for an upright sign. If there are double broken lines across your lane, you must give way even with no sign.
