Temporary signs at roadworks: which ones take priority?

Temporary signs warn of changes and hazards caused by roadworks. Drivers must follow the route actually laid out and directions from police officers.

Roadworks change the road

Roadworks may narrow the carriageway, move lanes or require traffic to alternate in one direction at a time. Temporary signs give advance warning and guide traffic through a temporary layout. Yellow is commonly used for temporary signs, but you still need to read the specific message and the arrangement on site carefully. Slow down and leave more distance, as workers, machinery and obstacles may be close to your lane.

When temporary signs differ from permanent signs, follow the temporary traffic arrangements for the roadworks and any directions from police officers. Do not choose a route based on a familiar sign if a temporary sign or barrier changes it. Temporary road markings and physical barriers may show which lane is open; do not cross them to recover a missed turn.

• Slow down before the roadworks and look out for workers and vehicles.
• Follow the temporary lanes, cones, barriers and signs in sequence.
• Give way to police officers directing traffic.

Alternating one-way traffic and diversions

On a narrow stretch, traffic may be controlled by lights, traffic marshals or priority signs. Wait your turn and do not enter if the queue blocks the work area or leaves you with no room to exit. For a diversion, follow the arrows and check for any height, weight or vehicle-type restrictions. An alternative route for cars may not suit heavy vehicles or vehicles towing a trailer.

If signs are covered, displaced or contradictory, proceed cautiously and report the problem to the road authority when possible. Do not stop suddenly to read a sign; find a safe place. Workers are close to moving traffic: leave them room and do not enter a closed lane.

Prepare and take care

At night, cones and workers at roadworks may be harder to see; use appropriate lights and speed, and leave room to stop. Avoid distractions and do not follow the vehicle in front too closely, as it may stop before a closed lane. If traffic is controlled by marshals, wait for a clear signal and do not treat an open gap as permission to go: oncoming traffic may still be passing.
