Lane 3 of 3 Narrow Sign – WK 106 | Temporary Ireland Traffic Sign

Lane 3 of 3 Narrow Sign – WK 106 | Temporary Ireland Traffic Sign

The WK 106 – Lane 3 of 3 Narrow Sign is a vital regulatory traffic sign used at the start of a narrowed lane system on a three-lane carriageway. It is specifically designed to inform drivers that Lane 3 has restricted width, typically due to ongoing roadworks or safety barriers. The inclusion of the 2.85m width restriction symbol ensures that wide vehicles are alerted in advance, promoting proper lane choice and preventing bottlenecks or safety hazards.

This sign must be installed on both sides of the carriageway to maximise visibility and ensure compliance. It is most commonly used during Level 3 traffic management setups, where space is restricted but multiple lanes remain open.

Compliant with Chapter 8 of the Traffic Signs Manual and made from high-visibility materials, the WK 106 sign is essential for protecting road users and workers in complex temporary road layouts.
