Lane-use control by regulation: what it means

What it means

A diagram shows that the right-hand lane of a two-lane carriageway, or part of a carriageway, falls under a command or prohibition regulatory sign. What that regulatory sign requires is compulsory there. Opposing traffic flow is shown by a dotted arrow.

What you must do

Make sure in time that there is a big enough gap in the traffic to merge with the traffic. Also yield (give way) to other traffic which might merge.

Remember

The diagram shows the lane where the regulatory sign applies.
