U36 Temporary Sign – Street Works Ahead (Right), 120x80 cm, Class II

U36 Temporary Sign – Street Works Ahead (Right), 120x80 cm, Class II

The 120x80 cm panel that announces works on a side street, before the junction, with class II prismatic sheeting. It is a town sign: you see it on the main street and learn that the street to the right is under works.

Why class II

Class II (RA2) prismatic sheeting shows up three to four times better at night than class I sheeting, even among plant lights and street lights. For temporary signing, SR 1848-2 adds a clear rule: a temporary sign must have at least the retroreflection class of the permanent signs on the section, so on roads already signed in class II it is the compliant choice.

Where it goes, under SR 1848-1:2024

It goes on the street that crosses the one where works are carried out, so drivers learn before the junction that there are works on the street to the right and can choose another route in good time.

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.
