Road markings in the UK serve as essential guides for motorists to ensure safe driving and traffic management. They can be quite complex due to the numerous variations in shapes, colours, and locations. In this article, we provide a detailed explanation of the various road markings you may encounter, as per the Highway Code, to help you navigate the roads with confidence.

Across the Road: Essential Stop and Give Way Lines

Road markings that run across the road are crucial for controlling traffic flow and ensuring safety at junctions, roundabouts, and traffic signals. Here are the most common ones:

Stop Line at Signals or Police Control

A white line across the road indicates a stop line, commonly found alongside traffic lights or areas under police control. Ensure you stop before the line when directed by traffic lights or a police officer. Take note not to roll into a cycle box at the advanced stop line (ASL) if present.

Stop Line at 'Stop' Sign

A thicker white line, less common than those found alongside traffic lights, appears next to stop signs. This marking reminds drivers to stop and give way to traffic before proceeding when safe. You'll typically find this line at junctions without traffic lights.

Give Way to Traffic on Major Road

White, double broken lines signal drivers to give way to traffic on major roads. Drivers don't always need to stop at this line but should remain vigilant for crossing traffic. These markings are common at mini roundabouts and junctions with major roads.

Give Way to Traffic from the Right at Roundabouts

Broken white lines at larger roundabouts remind drivers to give way to traffic from the right.

Give Way to Traffic from the Right at Mini Roundabouts

A thicker, broken white line signifies that drivers must give way to traffic from the right at mini roundabouts, which are common on local roads.

Along the Road: Markings that Guide Traffic Flow

Road markings painted along the carriageway help manage traffic flow and warn drivers of potential hazards. Some common examples include:

Edge Line

Edge lines are white, sometimes ribbed, and appear on the left-hand side of the road. They mark the edge of the carriageway and guide drivers in maintaining a safe, lateral position. You'll likely find these in areas prone to fog and mist, at sudden changes of road width, and on unlit stretches of road.

Centre Line

Centre lines are white, broken, and run down the middle of the road. They separate opposing traffic flows and vary in length and gap size depending on the speed limit. These are among the most common road markings.

Hazard Warning Line

Hazard warning lines resemble centre lines but feature longer painted sections and shorter broken gaps. They warn drivers of non-obvious hazards, such as approaching junctions or central refuges.

Double White Lines

Double white lines can appear in several configurations:

  • Nearest line is broken: According to Rule 128 of the Highway Code, you may cross the lines to overtake if it is safe and you can complete the manoeuvre before reaching a solid white line on your side.
  • Nearest line is solid: Rule 129 of the Highway Code states that you must not cross or straddle these lines unless it is safe and necessary to enter adjoining premises or a side road.
  • Both lines are solid: These lines prohibit drivers from using the opposing traffic lane, typically where overtaking visibility is restricted. You must not stop on roads marked with double white lines.

Parking and Loading Markings: Along the Edge of the Road

Road markings along the edge of the road often indicate parking and waiting rules. Some common examples are:

Single Yellow Line

Single yellow lines indicate that waiting is restricted during specified times, which are usually displayed on nearby signs. If there are no signs, the waiting restrictions apply every day, including Sundays and Bank Holidays. These are usually for car parking marking lines are often found on residential streets.

Double Yellow Lines

Double yellow lines signify that no waiting is allowed at any time. Sometimes, nearby signs indicate seasonal restrictions. You can find double yellow lines on many busy roads.

White Bay Markings

White bay markings are rectangular and feature broken lines. Signs nearby specify the allowed waiting or parking durations during the designated dates and times. If no signs are present, the waiting restrictions apply throughout the year, including Sundays and Bank Holidays.

Loading Bays

Loading bays resemble white parking bays, with a rectangular shape and broken white lines. The words "loading only" appear along the edges of the bay, and a white sign indicates whether parking is limited to goods vehicles and the times at which restrictions apply. Parking without loading is prohibited in these bays, which are typically found along high streets and outside shop parades.

Named Bays

Named bays are rectangular and feature a broken white line. Words such as "DOCTOR" or "POLICE" appear beside the bays to indicate their designated use. These markings can appear in various areas, especially those popular with car-sharing services, where the words "CAR CLUB" are painted.

Kerb Markings: Loading Rules

Double Yellow Kerb Lines

Double yellow lines painted across kerbs indicate that loading or unloading is prohibited at all times. These markings usually appear with a white sign reading "No loading at any time". Drivers may stop near double yellow kerb lines to drop off and pick up passengers. Like single yellow lines, these markings often appear on high streets and outside shop parades.

Single Yellow Kerb Line

Single yellow lines are sometimes painted across kerbs to show that loading and unloading are restricted in that area. You should always check nearby signs for enforcement times and know that when days aren't specified, rules apply throughout the year. Drivers may stop near single yellow kerb lines to drop off and pick up passengers. You can expect to find these along high streets and near shop parades.

Additional Road Markings

School Keep Clear

Yellow zig-zags with the words "SCHOOL KEEP CLEAR" are painted to indicate that stationary vehicles are prohibited, even when picking up or dropping off children at school. These markings are found outside and near schools.

Give Way

A triangle pointing towards your car, featuring a thicker, straight line further away from your vehicle, indicates a give way line ahead. After seeing the marking, you should slow down and prepare to stop to let other road users pass. You can find these markings before various junctions and roads with different widths, where only one vehicle is permitted to pass.

Bus Stop

Bus stop markings are rectangular and made up of a yellow, broken line with the large words "BUS STOP" painted inside. You must not park within the marking at any time, and these markings can be found across a range of roads.

Bus Lane

Lanes reserved for buses are marked with the words "BUS LANE" and are usually accompanied by signs that indicate if any other vehicles are ever permitted to use them. Rule 141 of the Highway Code states that "You may enter a bus lane to stop, to load or unload where this is not prohibited." Bus lanes are often found on wider roads in built-up areas to prioritize travel for larger groups of passengers.

Box Junction

Box junctions are yellow boxes filled with criss-crossing yellow lines. You must not enter the box until your exit road is clear, but you may wait in one if you want to turn right and are only prevented from doing so by oncoming traffic or other vehicles waiting to turn right. Box junctions are commonly found at busy intersections, where they help to prevent traffic from blocking intersections and keep traffic flowing smoothly.

Cycle Lanes

Cycle lanes are designated spaces on roads for the exclusive use of cyclists. These lanes are marked by solid white lines and are often painted a different color, such as green or blue, to distinguish them from other traffic lanes. Sometimes, there are dashed white lines indicating a cycle lane, which means that drivers can cross them if necessary but should give priority to cyclists. Cycle lanes can be found in urban areas to encourage cycling as a means of transportation and to protect cyclists from other traffic.

Advance Stop Lines (ASLs)

Advance Stop Lines are a type of road marking designed to provide a safe space for cyclists to wait at traffic lights ahead of other traffic. ASLs consist of a large rectangle with a solid white border, often painted a different color, such as green or blue. A smaller, dashed white line marks the area where other vehicles must stop. These markings can be found at traffic light-controlled intersections in areas with high levels of cycling.

Hatched Markings

Hatched markings are diagonal stripes, usually white or yellow, that create a buffer zone between lanes or on the side of the road. They are intended to separate traffic and provide an extra margin of safety. Hatched markings are often found on highways, dual carriageways, or around junctions to prevent drivers from merging or changing lanes too closely to other vehicles.

In conclusion, it is essential to understand and recognize various road markings to ensure your safety and the safety of other road users. Familiarize yourself with these markings and follow the rules and restrictions they represent to maintain a safe and efficient traffic flow.


What are the different types of road markings used in the UK?

The UK utilizes various types of road markings to convey important information to drivers and pedestrians. Some common types include white lines, yellow lines, arrows, symbols (such as pedestrian crossings and bicycle lanes), and hatched markings. These markings serve different purposes, such as indicating traffic lanes, providing guidance, and highlighting specific restrictions or warnings.

How do white and yellow road markings differ in their meanings and purposes?

White road markings are primarily used to separate traffic lanes, highlight the edges of the road, and indicate pedestrian crossings. They can also designate parking spaces, bus lanes, and cycle lanes. Yellow road markings, on the other hand, generally indicate restrictions or warnings, such as no parking zones, loading areas, and clearways. Yellow lines are often used to control parking and stopping restrictions.

What are the regulations and standards governing road markings in the UK?

Road markings in the UK are governed by various regulations and standards, including the Traffic Signs Regulations and General Directions (TSRGD) and the Manual for Streets. These regulations provide guidelines for the design, placement, and maintenance of road markings, ensuring consistency and safety across the road network. Local authorities and highway agencies are responsible for adhering to these standards.

How often are UK road markings repainted or maintained?

The frequency of repainting or maintaining road markings in the UK varies depending on factors such as traffic volume, weather conditions, and the type of road. Generally, major roads and highways with high traffic volumes are repainted more frequently than quieter residential streets. However, there is no set timeframe, and maintenance schedules are determined by local authorities based on their assessment of the road conditions.

Are there any specific road markings for pedestrian crossings in the UK?

Yes, pedestrian crossings in the UK are marked with distinct road markings to enhance safety and visibility. The most common type is the zebra crossing, which consists of alternating black and white stripes across the road. Zebra crossings are easily recognizable and give pedestrians priority over vehicles. Other types of pedestrian crossings include pelican crossings, puffin crossings, and toucan crossings, each with their specific road markings and signals.
