Product description
B3 Priority Sign – Priority Road, 60x60 cm, Class II
The white diamond with a yellow centre, in the class II prismatic sheeting version. It confirms priority on main roads and at the exit from towns, where it goes next to the road number sign.
Why class II
The difference from class I shows at night: class II (RA2) prismatic sheeting returns three to four times more light, and the gap grows when the sign is mounted at the side, far from the centre of the road. On lit streets with shop windows and advertising, SR 1848-2 requires prismatic class 2 or 3 sheeting. The standard guarantees a 10-year service life for class II sheeting, three years more than for class I.
Where it goes, under SR 1848-1:2024
It goes on priority roads: at the exit from a built-up area, on the same support as the road identification sign (F37–F40); outside built-up areas, 30–50 m after major junctions, to confirm the priority; in built-up areas, before a junction where the priority road changes direction, with the P21 additional panel; and before junctions with minor streets in towns and cities.

? Frequently asked questions
Where does it go?
It goes on priority roads: at the exit from a built-up area, on the same support as the road identification sign (F37–F40); outside built-up areas, 30–50 m after major junctions, to confirm the priority; in built-up areas, before a junction where the priority road changes direction, with the P21 additional panel; and before junctions with minor streets in towns and cities.
How does it differ from the class I sheeting version?
It is the same size as the B3, but with class II (RA2) prismatic sheeting, which returns three to four times more light and has a guaranteed 10-year service life instead of 7.
When is class II sheeting mandatory?
SR 1848-2 requires prismatic class 2 or 3 sheeting in areas with many light sources: street lighting, shop windows, advertising, dense urban areas. Elsewhere, class II is chosen for better visibility on fast roads and where the sign is seen at an angle.
Which fixings come with it?
The pack holds 2 clamps for Ø48 mm posts and 4 bolts with nuts. Clamps for Ø60 mm posts are available on request, a better fit for large signs or windy locations.
Which post should I order?
The post is ordered separately. For a fixed installation in a concrete foundation: the galvanised Ø48 mm post, 300 cm. For temporary use, with no foundation: the Ø48 mm tripod post, 120 cm. On concrete or paving, where you cannot dig: the Ø60 mm flange post, 300 cm, bolted down, for which you ask for the Ø60 mm clamps when you order.
How high is it mounted?
The bottom edge of the sign goes 1.50–2.50 m above the road or kerb, and the edge nearest the road 0.50–2.0 m from the road platform. The sign must be visible from at least 50 m in built-up areas and 100 m outside them.
Is the sign CE marked?
Yes. It is CE marked and complies with SR EN 12899-1:2007, the European standard for vertical road signs, and with SR 1848-1:2024, SR 1848-2:2011 and SR 1848-3:2011. The sheeting and the paint resist UV and weathering.
