Description

Road Narrows on Left Permanent Post Mounted Sign- Dia 517 R2/RA2 (Face Only)

The road narrows on the left sign to diagram 517L gives an advance warning of the road narrowing on the left (current) side. This means the thinning of the route creates a potential hazard because you will have to drive closer to oncoming traffic. If the narrowing doesn't remove a lane from the junction and the lane does not have a severe taper, the sign isn't needed. Table 4-1 on page 19 of the Traffic Signs Manual, Chapter 4 covers the specific taper criteria. The alternative version of this diagram is reversed, the "Road Narrows Right" sign would be used where the right (opposite) side of the road is forced closer to the centre line.

You will find this sign before thinning of the near side of the junction at a turning. It is necessary wherever a lane is lost on a single carriageway road or where the centre line has faded or omitted from wear. Vehicles with wide clearance may struggle the most in these areas, especially a turning. Therefore, supplementary plates can be used to further inform drivers of the potential hazards:

Diagram 511- "Reduce Speed Now"
Diagram 518- "Single File Traffic"
Diagram 519- "Single Track Road"
Diagram 572- "Distance Ahead"
Diagram 575- "Oncoming Vehicles in Middle of Road"

The standard size for this sign is 600mm, but the size can go up to 1500mm. Other sizing can be arranged if needed through calling our sales team.

Key features

R2 Class 2 Reflectivity

R2 (RA2) Reflectivity makes this sign suitable for use with vehicles and reflects around 32% of the light that hits the surface back to the driver. This material is also called HIP which stands for high intensity prismatic.

Post Mountable

Twin rear channels mean the sign face can be clamped in place and will not twist once secured. The clamps are available to supply separately and are not included with the sign face.

Composite Substrate

The backing of the sign is made from a rigid plastic sandwiched between two skins of aluminium making the sign strong and very durable. As there is no steel it will not rust giving a great lifespan.
