Where the 642 sign is used

Clearway signs mark roads where a stopped vehicle would be dangerous or disruptive.

  • The start of a clearway, with a supplementary length plate
  • The end of a clearway, with an End plate
  • Both sides of the road, mounted in pairs where necessary
  • Repeater positions at regular intervals along the route

Frequently asked questions

What does the 642 sign mean?

It marks a clearway - a stretch of road where stopping is prohibited, usually because the speed and design of the road make a stopped vehicle a hazard.

How should clearway signs be laid out?

The start must be marked with this sign plus a supplementary plate giving the clearway length in miles, and the end with this sign plus an End plate. Place signs on both sides of the road where necessary and use repeaters at regular intervals.

Can I use this sign on a public highway?

Yes. It is manufactured to BS EN 12899-1:2007 and UK highway regulations, CE marked, with Class 2 RA2 reflectivity - the specification required for permanent road signs.

Do I get the post and clips with it?

No, this is the sign face only. Post-mounted variants include rear channels on the back; 76mm posts and anti-rotational clips are sold separately.

Can two signs be mounted back to back?

Yes. Clearway signs are commonly mounted in pairs on one post using back-to-back clips so the restriction reads from both directions.

Which sizes are available?

300mm, 450mm, 600mm and 750mm faces, each as a post-mounted or wall-mounted version.

What is the lead time?

Each sign is made to order, so allow 7-10 working days for dispatch.
