U32 Temporary Sign – Series of Work Sites, 180x120 cm, Class I

U32 Temporary Sign – Series of Work Sites, 180x120 cm, Class I

The 180x120 cm panel announcing at the outset several work sites on the same section, with the speed limit and the section length, with class I retroreflective sheeting.

When class I is used

The class I version is the economical choice for work sites on local roads: RA1 retroreflective sheeting with a 7-year service life. The SR 1848-2 rule is simple: a temporary sign must have at least the class of the existing signing on the section, and areas with many light sources call for prismatic class 2 or 3 sheeting. For national roads, lit boulevards or sections signed in class II there is the U32_II version.

Where it goes, under SR 1848-1:2024

It goes on roads where a section with a series of work sites must be announced. The panel does not replace the signing of each work site, which is still signed separately.

What the roadworks rules require (Order 1112/411/2000)

The sign belongs to the advance signing, which is installed first, ahead of the work zone in the direction of travel, with at least 50 cm of clear space outside the carriageway. The rules require signs to be stood on the ground first, to check that they are clearly visible, and only then fixed to a support; no more than two signs go on the same support or side by side, and on one-way roads or bends they can be repeated on the left side or above the road.

On public roads, works are signed under the methodological rules approved by Order MI/MT no. 1112/411/2000. The road closure or traffic restriction is approved by the road authority, with the traffic police's agreement, on the basis of a signing layout endorsed as final, a copy of which the contractor keeps at the work site. The contractor installs, completes and maintains the signing for the whole job, removes it at the end and restores the original signing; accidents caused by incomplete or missing temporary signing are entirely the contractor's responsibility.

At night, if the existing signing on the road is retroreflective, the temporary signing must be retroreflective too and can be supplemented with flashing or sequential (“cascade”) amber lamps; on main and connecting streets in towns, retroreflective temporary signs are supplemented with flashing amber lamps.
