Line marking on a public road in the UK is governed by a set of strict rules and regulations to ensure safety, consistency, and clarity for all road users. These rules are outlined in the Traffic Signs Regulations and General Directions (TSRGD) and must be adhered to by all contractors and local authorities.

Here are some key rules for line marking on public roads:

1. Regulatory Compliance

All road markings must comply with the standards set by the TSRGD. This includes the size, colour, and placement of lines. For example, double yellow lines indicate no parking at any time, while single yellow lines allow parking restrictions during specific times.

2. Correct Colour Usage

White lines are typically used to divide lanes or indicate the edges of the road, while yellow lines are used to indicate parking restrictions. Red lines, found in some urban areas, indicate no stopping at any time.

3. Reflectivity

Road markings must be reflective, particularly on high-speed roads, to ensure they are visible during night-time or in adverse weather conditions. Reflective beads are often embedded into the paint to enhance visibility.

4. Durability

Given the high level of wear and tear on public roads, line markings must be durable. This often involves using thermoplastic paint, which is long-lasting and resistant to fading.

5. Safety Considerations

Line markings must be placed in a way that enhances road safety. This includes ensuring that markings are clear and unambiguous, with adequate spacing between them to prevent confusion among drivers.

6. Authorisation

Any changes or additions to road markings on public roads require authorisation from the relevant local authority. This ensures that all markings are part of a coherent traffic management plan.

7. Maintenance

Regular maintenance of road markings is essential to keep them visible and effective. Faded or damaged markings must be promptly repainted or repaired.
