Pre-Worboys sign

In the early days of motoring, uneven roads were par for the course, so there was no need to sign such things. Even in the 1960s, only the most important routes were up to what we now consider a modern standard. Drivers still expected to find bumps on the narrow country lanes.

Worboys Report sign

Sadly this sign seems to be becoming more common on the UK roads. Its original purpose seems to have been to sign specific uneven patches in otherwise smooth roads, perhaps in places where the road was liable to subsidence such as over old coal mines or low-lying land where drainage or peat extraction caused the road to move, such as the Fens or Somerset Levels.

The sign features two identical bumps in quick succession on a thick black horizontal line. The bumps share roughly the same profile, albeit scaled down, as the Hump Bridge sign.

Irish sign

Irish sign W 133 Uneven Road

The symbol within the standard yellow diamond of Irish sign W 133 Uneven Road is similar to that of the corresponding UK sign, but has three humps instead of two. The Department of Transport's Traffic Sign Manual states that it "should be regarded as temporary, pending remedial work to the carriageway and should be removed following repairs".

A supplementary plate indicating the length (in metres) of the uneven road section is used where this exceeds 400 m.
