UK Road Markings Guide: Types, Meanings & Best Practices
Road markings are one of the most important elements of traffic safety. They guide drivers, control traffic flow, and help ensure compliance with the Highway Code. Whether on public highways, private estates, or commercial car parks, clear and well-maintained road markings are essential.
This guide explores the different types of UK road markings, what they mean, and how to keep them compliant and visible.
Markings Across the Road
These are the most familiar markings, seen at junctions, signals, and intersections:
- Stop Lines – Solid white lines across a lane, requiring vehicles to stop at traffic lights or stop signs.
- Give Way Lines – Broken white lines (sometimes double broken) used to indicate priority to other traffic.
- Junction Markings – Variations of solid and broken lines controlling entry and exit points at roundabouts and crossroads.
These markings regulate priority and prevent collisions at busy points.
Markings Along the Road
Road markings along the carriageway guide positioning and highlight hazards:
- Centre Lines – Broken white lines that divide traffic directions. The length of dashes and gaps changes with speed limits.
- Edge Lines – Solid white lines marking the edge of the road; often ribbed for tactile/visual guidance.
- Hazard Warning Lines – Broken lines with shorter gaps, warning drivers of potential danger ahead (e.g. sharp bends).
These provide constant guidance and encourage safe overtaking and positioning.
Parking & Loading Markings
Road markings also regulate parking and loading behaviour:
- Single Yellow Line – Waiting restrictions apply during specified times (shown on nearby signs).
- Double Yellow Lines – No waiting at any time unless otherwise signed.
- White Parking Bays – Designated spaces for parking; signs indicate permitted use.
- Loading Bays – Areas marked “Loading Only”, often with time restrictions.
Clear markings prevent congestion and ensure fair use of roadside space.
Kerb Markings
Markings on kerbs control loading and unloading:
- Single Yellow Kerb Lines – Loading restrictions during certain times.
- Double Yellow Kerb Lines – No loading at any time.
Always check signage for details, as restrictions vary locally.
Other Common Road Markings
- School Keep Clear (zig-zag lines) – Yellow zig-zags outside schools where stopping is prohibited.
- Box Junctions – Yellow criss-cross lines; vehicles must not enter unless their exit is clear.
- Cycle Lanes – Marked lanes (sometimes coloured) to separate cyclists from traffic.
- Advance Stop Lines (ASLs) – Areas giving cyclists priority at traffic lights.
- Hatched Markings – Diagonal/chevron areas used to separate lanes or protect turning space.
These improve safety for vulnerable road users and reduce congestion.
Regulations & Compliance
All UK road markings must comply with the Traffic Signs Regulations and General Directions (TSRGD). This covers dimensions, colours, and positioning to ensure consistency across the road network.
Even on private land — such as car parks, retail parks, or business estates — following the same standards helps drivers instantly recognise and understand markings.

Maintenance & Lifespan
Road markings wear down over time due to weather, traffic, and road surface conditions.
Best practice includes:
- Regular inspections to spot fading or damage.
- Repainting before markings become unclear.
- Using durable, high-quality materials for longer life.
