For further information on road markings in the UK please see the related link to the Highway Code.
A solid yellow line next to a broken yellow line means that vehicles next to the broken line may pass. The yellow lines define the road as two way, traffic opposing each other. The side of the road with the solid yellow line facing it is a no-passing zone, while the opposite side of the road, with the intermittent line facing it, passing is permitted.
In the USA: Two way traffic divider, passing (both sides) allowed.

Two way traffic - the lane with the broken side is permitted to cross over to the other side to pass, the lane with the solid line is not.
