V9 Barrier Board, 200x25 cm, Class II

V9 Barrier Board, 200x25 cm, Class II

The long 200x25 cm barrier board with red and yellow blocks that marks off the site along the road, with class II prismatic sheeting. At night, the brighter sheeting clearly shows the edge of the work area.

Why class II

On national roads and lit streets, permanent signing is often class II, and SR 1848-2 requires temporary signs on the same section to have at least the same class. Class II (RA2) prismatic sheeting returns three to four times more light than class I and has a guaranteed 10-year service life, so the sign can be used on one site after another.

Where it goes, under SR 1848-1:2024

It is used to mark the length of the works, along the zone being worked 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.
