Lane Loss (Two to One Lane) Sign – W091 | Permanent Ireland Traffic Sign

Lane Loss (Two to One Lane) Sign – W091 | Permanent Ireland Traffic Sign

The Lane Loss (Two to One Lane) Sign – W091 | Permanent Ireland Traffic Sign is used to alert drivers that a two-lane roadway is about to narrow to a single lane, requiring a safe and timely merge. This warning is crucial for maintaining smooth traffic flow and avoiding sudden lane changes or last-minute braking.

The sign features two merging arrows, one straight and one curving inward, over a yellow diamond background with a black shoulder, clearly indicating the loss of a lane. As defined in Chapter 6 of the Traffic Signs Manual (TSM), this sign is essential on dual carriageways, bypasses, and transition points where multi-lane sections reduce due to roadworks, design constraints, or traffic-calming measures.

Technical Review

Manufactured to EN12899-1 standards and fully compliant with TSM 2024 updates, the W091 sign is engineered for clarity, visibility, and resilience. Its visual language ensures that drivers can recognise the need to merge well in advance, reducing risk and promoting road discipline.

Proper placement is critical before lane drop zones, tapered merges, or narrow bridge approaches, giving drivers time to adjust position and speed safely.
