642 stopping prohibited sign face - the clearway sign
The diagram 642 sign tells drivers that stopping on a stretch of road is prohibited. Better known as the clearway sign, it is used where the speed and design of the road make stopped vehicles a hazard. This sign face is manufactured to BS EN 12899-1:2007 and UK highway regulations, CE marked, with Class 2 RA2 high-intensity reflectivity, so it is suitable for permanent use on public highways as well as private roads. Each face is 3mm aluminium composite, available in four sizes from 300mm to 750mm for post or wall mounting.

Where it is used
Clearway signs mark roads where a stopped vehicle would be dangerous or disruptive:
- The start of a clearway, alongside a supplementary plate showing its length in miles
- The end of a clearway, paired with an End supplementary plate
- Both sides of the road where necessary, mounted in pairs with back-to-back clips
- Repeater positions at regular intervals along the clearway
Sizes and mounting
Four face sizes - 300mm, 450mm, 600mm and 750mm - each available post mounted or wall mounted. Post-mounted faces are supplied with rear channels that clamp to the post with anti-rotational clips, so the face cannot twist out of position; posts and clips are sold separately. Wall-mounted faces come with no holes - the composite drills easily for screw fixing, or bonds to the wall with a no-nails adhesive.
