C38 Prohibition Sign – Alternate-Side Parking, Odd Days, Ø60 cm, Class I

C38 Prohibition Sign – Alternate-Side Parking, Odd Days, Ø60 cm, Class I

The C38 bans parking on odd days of the month. It is recognised by the single white vertical stripe on the blue disc; its partner, the C39, has two stripes and applies on even days.

When class I is used

The sign has class I (RA1) retroreflective sheeting: 70 cd/(lx·m²) for white and a 7-year service life. It is the economical choice for places without many light sources, such as local, minor and private roads or streets without strong lighting. Where there is street lighting, shop windows or advertising, SR 1848-2 requires prismatic class 2 or 3 sheeting, which stands out better against a lit background.

Where it goes, under SR 1848-1:2024

It goes on sections where parking is banned on odd days of the month (1, 3, 5, … 29, 31), under the same conditions as the C36 (no parking). The P34 (except residents) or P18 (exempted vehicle categories) additional panels can go under it.

Technical data

• weight: 3 kg;
• fixings included: 2 clamps for Ø48 mm posts and 4 bolts with nuts;
• CE marked; compliant with SR EN 12899-1:2007, SR 1848-1:2024, SR 1848-2:2011 and SR 1848-3:2011.

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 60 cm diameter is the normal format in SR 1848-2, for county and local roads, streets and private roads open to public traffic. National roads call for the large Ø80 cm format and motorways for the very large Ø100 cm one; the standard forbids using a smaller format than the road category requires.
