Steep Ascent Sign – W106 | Permanent Ireland Traffic Sign

Steep Ascent Sign – W 106 | Permanent Ireland Traffic Sign

The Steep Ascent Sign – W 106 | Permanent Ireland Traffic Sign is a crucial warning sign designed to alert drivers to a steep uphill gradient on the road ahead. Recognised by its iconic triangular shape with a black incline and percentage grade (e.g. 15%) on a yellow background, the W 106 sign ensures motorists are forewarned to prepare for increased engine strain and reduced vehicle performance when ascending.

As outlined in Chapter 5 of Ireland’s Traffic Signs Manual (TSM), the W 106 sign plays an essential role in maintaining road safety on routes with significant elevation changes. It is especially relevant in hilly or mountainous regions, where heavy vehicles, older cars, and cyclists may need additional warning to assess speed, gearing, and acceleration needs. This sign not only protects individual road users but also enhances overall traffic flow and vehicle handling in challenging terrain.

You’ll typically see the W 106 installed in advance of steep hills on national, regional, and local roads across Ireland, particularly in areas like the Wicklow Mountains, Kerry, and parts of the Wild Atlantic Way where abrupt gradients are common.
