Safety at roadworks

Highways England is working with the industry and road users to reduce the risks of working on the roads. For the safety of road workers and all road users, when you are approaching roadworks:

Keep within the speed limit – it is there for your safety.

Get into the correct lane in good time – don’t keep switching.

Concentrate on the road ahead, not the roadworks.

Be alert for works’ traffic leaving or entering roadworks.

Keep a safe distance – there could be queues in front.

Observe all signs – they are there to help you.

And be alert for road workers, the roads are their workplace.
