What does the Change lane signal sign mean?
Tells you to move to the lane the arrow points to, usually because your lane is closed further ahead.
What it means
Move out of this lane into the next lane in the direction of the arrow.
The angled arrow shows which way to move. It may point to the left or to the right.
Check your mirrors, signal and move over in good time. A red X with red lights usually follows over the lane you are leaving.
Where you'll see it
On motorway signals above the lanes, before a lane closure.
Rules to know
