Road Depression Sign – W131 | Permanent Ireland Traffic Sign

Road Depression Sign – W131 | Permanent Ireland Traffic Sign

The Road Depression Sign – W131 | Permanent Ireland Traffic Sign warns road users of a sudden dip or depression in the road surface. This change in elevation can affect vehicle handling, especially at speed, and is particularly important for heavy goods vehicles, buses, and low-clearance vehicles that may experience discomfort or loss of control if unprepared.

Featuring a black depression icon on a high-contrast yellow diamond background, this sign is officially referenced in Chapter 6 of the Traffic Signs Manual (TSM) and is an essential part of roadway hazard warning systems. It is used in both rural and urban settings, wherever subsidence, surface settlement, or engineered depressions are present.

By alerting drivers to reduce speed and be prepared for changes in road contour, the W131 enhances driving safety and reduces the risk of suspension damage or cargo shift.
