554 flood road sign face for flooded roads and flood-prone routes
The 554 flood road sign is the recognised warning triangle for a flooded road, manufactured to BS EN 12899-1:2007 and UK Highway Regulations for use on public highways and private roads. The 3mm aluminium composite face carries Class 2 R2/RA2 high-intensity reflective sheeting in red, white and black, so drivers pick it up early in exactly the low-light, wet conditions it is there to warn about. Choose a post mounted face supplied with rear channels or a plain wall mounted face, in 450mm, 600mm or 750mm sizes.
Key features

BS EN 12899-1:2007 and CE marked - meets the legal requirement for permanent signs installed on the public highway.
-
Class 2 R2/RA2 reflectivity - high-intensity sheeting reflects headlights back at drivers in low light.
-
3mm aluminium composite - weatherproof face with a grey rear that withstands year-round outdoor use.

-
Three sizes - 450mm, 600mm or 750mm to suit the road and approach speed.
Where it is used
The flood sign should only be displayed when the road is flooded or expected to flood in the near future, so it earns its place on:
- Flood-prone rural routes and low-lying lanes
- Ford crossings and riverside roads
- Council and highways depots holding seasonal flood signage
- Private roads and estates that take on water in heavy weather
Using the 554 correctly
The sign may be paired with a distance plate showing the length of the flooded section, and can include a left or right arrow. At the far end of the flood, a 554.1 Try Your Brakes sign warns drivers to test their brakes, and if the water makes the road impassable, ROAD AHEAD CLOSED signs should be used at the junctions on either side.
Sizes and mounting
Wall mounted faces are supplied without holes - the aluminium composite drills easily for screw fixing, or fixes with a no-nails adhesive. Post mounted faces come with rear channels that clamp to a 76mm post with anti-rotational clips, so the face cannot twist out of position. This product is the sign face only; posts and clips are sold separately.
