Lane Loss (Four to Three Lanes) Sign – W093 | Permanent Ireland Traffic Sign

Lane Loss (Four to Three Lanes) Sign – W093 | Permanent Ireland Traffic Sign

The Lane Loss (Four to Three Lanes) Sign – W093 | Permanent Ireland Traffic Sign alerts drivers that a four-lane roadway is about to reduce to three lanes, prompting them to merge safely and adjust their driving position. This sign plays a vital role in traffic lane management, especially on high-capacity roads like dual carriageways and motorways, where changes in lane availability can cause confusion or congestion.

The design includes four upward arrows, with the leftmost arrow curving into the main carriageway, indicating the lane loss, and a distance panel (e.g., 400m) below the symbol for advance notice. This sign is included in Chapter 6 of the Traffic Signs Manual (TSM) and is typically placed before merge-in-turn sections, construction zones, or lane closures due to engineering works.

Technical Review

This W093 sign is built to EN12899-1 specifications and is compliant with the latest TSM 2024 updates. It is essential for ensuring drivers have adequate notice to merge smoothly, reducing sudden lane-switching and promoting a more even traffic flow.

It’s particularly effective on busy urban motorways, national primary roads, and temporary diversions, where drivers must make quick, safe decisions about merging.
