Lane 3 of 3 Closed Sign – WK 042 | Temporary Ireland Traffic Sign

Lane 3 of 3 Closed Sign – WK 042 | Temporary Ireland Traffic Sign

The WK 042 – Lane 3 of 3 Closed Sign is a critical temporary traffic sign used to indicate that Lane 3 of a three-lane carriageway is closed ahead. This sign is specifically designed for use on Level 3 roads, including motorways and major dual carriageways, where lane closures must be clearly communicated well in advance to ensure safe vehicle merging and continued traffic flow.

It plays an essential role in reducing last-minute lane changes and helping drivers adjust their position early. WK 042 ensures compliance with Chapter 8 Temporary Traffic Management Plans (TTMPs) and is often used in coordination with advance warning signs, lane taper systems, and portable VMS units.

By visually showing that the outer (rightmost) lane is closed, this sign improves driver confidence and facilitates orderly merging behaviour during roadworks or emergency closures.
