Road Narrows on One Side Sign – W070 | Permanent Ireland Traffic Sign
The Road Narrows on One Side Sign – W070 | Permanent Ireland Traffic Sign is an essential safety warning used to alert drivers that the road width will reduce on one side, either the left or right, depending on placement. This advanced notice is vital for preventing collisions and ensuring vehicles adjust their lane position and speed when approaching a narrowing carriageway.
The W070 sign features a bold black road symbol with one side curved inward, clearly indicating the affected narrowing side. Displayed on a high-visibility yellow diamond background, this sign complies with Chapter 6 of the Traffic Signs Manual (TSM) and is frequently installed where road works, natural erosion, or design constraints create a width reduction.
