F15 Direction Sign – Bus Lane, 50x65 cm, Class I

F15 Direction Sign – Bus Lane, 50x65 cm, Class I

The F15 shows that, on the section ahead, one lane is reserved for public transport: a diagram of the road with the right-hand lane separated and a disc reading REZERVAT BUS.

When class I is used

Class I means RA1 retroreflective sheeting, with 70 cd/(lx·m²) for white and a 7-year service life. It suits places where the sign does not compete with other lights: roads and streets without strong lighting, local, minor and private roads. In areas with many light sources, such as streets with public lighting, shop windows and advertising, SR 1848-2 requires prismatic class 2 or 3 sheeting, because a class I sign gets lost against the background there.

Where it goes, under SR 1848-1:2024

It goes at the start of sections with at least two lanes in each direction where one lane is reserved for certain vehicle categories, and is repeated after every junction. Between junctions, F28 signs (lane reserved for certain vehicle categories) or, above the lane, D10 signs (compulsory route for the vehicle category) are used.

Direction signs guide drivers and show special-purpose lanes on the carriageway. On ordinary public roads they have a blue background with white lettering, and on motorways a green one.

Mounting and size

Fixings for the post are included: 2 clamps for Ø48 mm posts and 4 bolts with nuts; clamps for Ø60 mm posts are available on request. 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.

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 it, ask for the Ø60 mm clamps when you order.

The panel measures 50 x 65 cm.
