Where the two-way traffic sign works

The diagram 521 triangle is used wherever drivers need warning that two-way traffic is ahead.

  • One-way sections returning to two-way running
  • Contraflow and lane-closure schemes on highways and street works
  • Construction and utility works with traffic in both directions
  • Events and estate roads with oncoming vehicles

Frequently asked questions

What does diagram 521 mean?

It is the number for the two-way traffic warning sign - a red-bordered triangle with two black arrows pointing in opposite directions. It warns drivers to expect oncoming traffic, usually where a one-way road returns to two-way running.

Does the price include a frame?

There are two options. Sign Face Only is just the 750mm triangle face, for frames you already own. Include Frame and Clips adds a 750mm triangle metal frame and the clips that hold the face in place.

Can I swap this face onto another frame?

Yes. The faces are interchangeable, so you can move them between frames and keep one frame working across several signs.

How visible is it at night?

The face is Class 1 (RA1) retroreflective, so it returns headlight glare to the driver and stays legible in low light and darkness.

How do I stop it blowing over?

Mounted in its frame the sign can be weighted with sandbags. We stock ready-filled sandbags if you need them.

What are the dimensions and weight?

The sign face is 860mm wide by 750mm high and weighs 2.7kg. The frame is 1080mm high by 870mm wide and weighs 7.74kg.

How long does delivery take?

Delivery is typically 1-5 working days for both options. Get in touch if you need it for a fixed start date and we will confirm timing before you order.
