What should you do?
Approach slowly and be ready to stop; cross only when you can clear the first carriageway safely and the median gap is long enough for your vehicle.
How to recognise it
Yellow diamond with two parallel black horizontal bars and a vertical line passing through both.
Common confusion
The line continuing through both bars is what separates it from the T-junction with a dual carriageway sign.
