Dual Carriageway Ends Post Mounted Sign - Dia 520 R2/RA2 (Face Only)
The dual carriageway ends sign (diagram 520) means that the section of dual carriageway is coming to an end and normal two-way traffic will resume. The diagram resembles the "Road Narrows on Both Sides" sign, however, this can be told apart as both lines join together to represent the two lanes joining into one. The Dual Carriageway sign is sometimes called the 'End of Dual Motorway' sign but is only used on carriageways.
The sign warns drivers that oncoming traffic will be closer and that there will no longer be two lanes passing in each direction. Usually, the "Two Way Traffic" sign is positioned after to emphasise this. Details on where this sign should be located can be found in the TSRGD Traffic Signs Manual, Chapter 4 which can be found on our regulations page.
Supplementary plates you can use with this sign are:
- Diagram 511- "Reduce Speed Now"
- Diagram 572- "Distance Ahead"
- Diagram 518- "Single File Traffic"
