- Warning of a staggered junction ahead where side roads meet the main road on alternating sides rather than directly opposite one another.
What the Staggered side-road junctions ahead sign means
Two side roads are coming up close together, but they are not opposite each other — one joins from one side and the next joins from the other side a little further on.
What you must do
Slow down and watch both sides of the road. Expect vehicles to emerge or turn from one side and then the other in quick succession, and be ready to give way as required.
