Road Works
Road works (sometimes written as roadworks) are temporary changes to the road layout so maintenance, repairs or improvements can be carried out. They often involve lane closures, temporary speed limits, traffic cones, barriers and road workers close to moving traffic. Understanding how to approach and drive through road works safely is essential for passing the DVSA driving theory test and for staying safe on real UK roads.
Use this Road Works guide to learn the key rules for learner drivers, see how they apply in everyday driving, and help you prepare for the UK

What are road works?
Road works are temporary changes to the road layout so work can be carried out safely. They can appear on all types of roads, from quiet residential streets to busy dual carriageways and motorways, and you must be ready to adjust your driving when you see the signs.
-
Temporary warning signs, cones, barriers and road markings guide you through the works area.
-
Lanes may be narrowed or closed, and traffic can be moved onto the opposite carriageway in a contraflow system.
-
Temporary speed limits will often apply and may be enforced by speed cameras.
-
Road workers may be on or very close to the carriageway, sometimes stepping into the road.
-
Temporary traffic signals or 'Stop/Go' boards may be used to control the flow of vehicles.
In your theory test, you'll be expected to recognise road works signs, understand how they affect speed and lane choice, and know how to drive in a way that keeps road workers, pedestrians and other road users safe.
Key road works rules
As a learner driver or rider, you need to show that you can spot road works early, follow all temporary signs and keep everyone safe in and around the works area. Here are the key road works rules you should know:
-
When you see a "Road works ahead" sign or temporary speed limit, slow down in good time, be prepared for lane changes and follow all signs and signals.
-
Obey temporary speed limits – they are there to protect both road users and road workers and may be enforced by cameras.
-
Follow lane closures and contraflow systems carefully. Get into the correct lane in good time, never drive in a lane marked with cones or a red "X", and do not change lanes at the last moment.
-
Keep a safe distance from the vehicle in front, especially where lanes are narrow, surfaces are uneven, or traffic is repeatedly stopping and starting.
-
Watch for road workers and vulnerable road users (such as cyclists, motorcyclists and pedestrians) near the works. Be ready to slow down or stop if they step into the road unexpectedly.
-
Where road works affect pedestrians, take extra care near temporary crossings, narrowed footways and diversions. Expect people to appear suddenly from between vehicles, barriers or equipment.
-
At night or in poor visibility around road works, use appropriate lights, reduce your speed further and be prepared for sudden changes in lane layout or direction.
These road works rules are based on Rules 288–290 of the UK Highway Code, which cover driving safely through road works and protecting road workers and other road users. Want to see the Highway Code road works rules?

Typical road works signs and layouts
-
"Road works ahead" sign: warns you that road works are ahead – start to slow down and look for temporary speed limits, cones and lane changes.
-
Temporary speed limit signs: show a lower speed limit through the works area – this limit is mandatory and may be enforced by speed cameras.
-
Lane closed and "merge in turn" signs: indicate that one or more lanes are closed ahead – move into the correct lane in good time and do not drive past the last safe opportunity to merge.
-
Single file traffic / contraflow systems: traffic in both directions may share one side of the road or use narrower lanes separated by cones or barriers – keep your speed down and your position central in the lane.
-
Temporary traffic signals or "Stop/Go" boards: control traffic where the road is too narrow for opposing flows – stop when instructed and only proceed when the signal, board or road worker shows that it is safe.
-
"Road narrows" and uneven surface signs: warn you of restricted space, ridges, ramps or exposed ironwork – reduce speed and hold the steering wheel firmly.
Road works in real driving situations
Road works are not just something that appears in theory test questions – you'll encounter them regularly in real driving. You'll use your road works knowledge every time you:
-
Drive on motorways and dual carriageways with long stretches of road works, narrow lanes and average speed cameras.
-
Travel on busy A-roads where lane closures and temporary traffic lights manage traffic through a single open lane.
-
Use local roads where small works, pothole repairs or utility works may partially block the carriageway or footway.
-
Drive in poor weather or at night when signs, cones and workers are harder to see and you must slow down even more.
In your practical driving test, examiners will expect you to spot road works early, choose the correct lane, adjust your speed smoothly, follow all temporary signs and signals, and drive in a way that keeps road workers and other road users safe.
Road works theory test questions in the DVSA theory test
Road works appear in the multiple-choice part of the DVSA theory test in several ways. You may be asked:
-
What you should do when you see particular road works signs or lane closure markers.
-
How to drive safely through contraflow systems, narrow lanes or temporary traffic light-controlled sections.
-
How temporary speed limits, road workers, uneven surfaces and restricted space should affect your speed and following distance.
-
How to behave when road workers, pedestrians or cyclists are close to the carriageway in a works area.
