V10 Directional Barrier Board, 200x33 cm, Class I

V10 Directional Barrier Board, 200x33 cm, Class I

The 200x33 cm chevron board that closes the lane across at the ends of the works and shows which way to pass, with class I retroreflective sheeting.

When class I is used

Class I means RA1 retroreflective sheeting, with 70 cd/(lx·m²) for white, suited to roads with low and medium speeds and few light sources. In areas with street lighting, shop windows and advertising, however, SR 1848-2 requires prismatic class 2 or 3 sheeting, and on a section already signed in class II the temporary sign cannot have a lower class either. For national roads, lit boulevards or sections signed in class II there is the V10_II version.

Where it goes, under SR 1848-1:2024

It goes across the road, marking the start and end of the works, with the chevrons pointing to the side traffic passes on. SR 1848-1:2024 states that the fixing and positioning system shown is for information only, and SR 1848-2 sets the board at 1.0 m above the ground.

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

The barrier board belongs to the signing that marks the works, together with markers and cones, installed after the advance signing. The rules require simple and directional barrier boards to carry yellow-red retroreflective sheeting even where the existing signing is not retroreflective; in that case, the lengthwise edge of the work zone is also marked with steady or flashing amber lamps, such as the V8-Y and V8-YS.

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.
