Merging Traffic from Left Sign – WK 035 | Temporary Ireland Traffic Sign

Merging Traffic from Left Sign – WK 035 | Temporary Ireland Traffic Sign

Introduction

The Merging Traffic from Left Sign – WK 035 plays a critical role in managing road safety during temporary traffic arrangements, particularly where separated traffic streams converge. As outlined in Chapter 8 of the Traffic Signs Manual (TSM), this sign is used on the main carriageway when traffic merges from a left-hand entry point — typically after lane shifts or roadworks.

Its design — a black graphic on a fluorescent orange diamond background — instantly alerts motorists that another stream of traffic is entering from the left, prompting them to adjust speed and merge safely. This type of visual cue is essential on high-speed roads, motorways, and national routes where awareness and quick reaction times are crucial.

Whether used by contractors setting up contraflows or by local authorities managing motorway on-ramps during works, the WK 035 sign ensures merging manoeuvres happen smoothly and without incident.
