Use your own judgment; the limit is only advisory
Ignore the displayed limit
Obey the limit, but only during rush hour
Obey the speed limit
Rule 288 of the Highway Code states:
When the ‘Road Works Ahead’ sign is displayed, you will need to be more watchful and look for additional signs providing more specific instructions. Observe all signs – they are there for your safety and the safety of road workers.
- You MUST NOT exceed any temporary maximum speed limit.
- Use your mirrors and get into the correct lane for your vehicle in good time and as signs direct.
- Do not switch lanes to overtake queuing traffic.
- Take extra care near cyclists and motorcyclists as they are vulnerable to skidding on grit, mud or other debris at road works.
- Where lanes are restricted due to road works, merge in turn (see Rule 134).
- Do not drive through an area marked off by traffic cones.
- Watch out for traffic entering or leaving the works area, but do not be distracted by what is going on there. Concentrate on the road ahead, not the road works.
- Bear in mind that the road ahead may be obstructed by the works or by slow moving or stationary traffic.
- Keep a safe distance – there could be queues in front.
