National Roads- Unlit Area: RA1 if AADT<3500, RA2 if AADT is >3500. Lit Area: RA2. Regional Roads- Unlit Area:RA1. Lit Area: RA2. Local Roads- Unlit and Lit Area: RA1. Roadworks- Unlit and Lit Area: RA2. Signs W 030, W 031 and W 034 are available for indicating merging traffic. They should be used where two physically separated streams of traffic proceeding in the same direction join the same undivided section of carriageway. Sign W 030 should be used on the main carriageway where a stream of traffic merges from the left. Sign W 031 should be used on the minor stream (such as a motorway slip road) where the traffic has to merge with a stream of traffic on its right. Sign W 031, Merging with Traffic on Right, should only be used where it is considered that drivers might not expect a merging movement or might not be sure where it is. Thus, the sign should be provided where a long link road at a complex interchange is about to merge with another carriageway on the right. There is no need for the sign at a normal ‘diamond’ interchange on a motorway or dual carriageway, where the slip roads are relatively short and straight. When used, Signs W 030 and W 031 should not obstruct the drivers’ view of the merging traffic stream.
