Road signs are the silent communicators of the roads. They guide, warn, and regulate traffic, helping to maintain order and safety for everyone. Whether you're a new learner or an experienced driver, understanding road signs is essential not only to pass your driving test but to navigate UK roads confidently and safely.
This guide highlights the most essential road signs in the UK, breaking down what each one means and where you’re most likely to see it. While this list covers the most commonly encountered signs, you can always refer to the Highway code for a comprehensive collection of all UK road signs.
As car technology becomes more advanced, newer cars have built in sign recognition which is great if you have missed a sign, discover a range of new vehicles through our vehicle leasing options.
Learning about road signs is great if you are taking your driving test soon, once you pass, you’ll need a vehicle to get on the roads and put the signs in use, at AMT Auto we can help, discover our quality used vehicles for sale, and start your adventure.
Let’s dive into the first sign!
Speed limit signs are circular with a red border and a number displayed in the centre, representing the maximum speed allowed on that road in miles per hour (mph). The number indicates the maximum speed vehicles can travel under normal conditions. Exceeding this limit is illegal and can lead to fines, penalty points, or disqualification.
Where You’ll See It
No entry signs are circular with a red border and a solid white horizontal bar across the middle. This universally recognised sign prohibits vehicles from entering a road or area. Ignoring this sign can result in fines, penalty points, or dangerous situations as the road ahead may be restricted or one-way only.
The Give Way sign is triangular with a red border and the words "Give Way" displayed on a white background. It instructs drivers to slow down and yield to traffic on the main road before continuing. This sign is crucial for maintaining safety at intersections where traffic does not flow equally.
The Stop Sign is one of the most recognisable road signs in the UK, featuring a bold red octagon with the word "STOP" in white capital letters. This sign instructs drivers to come to a complete stop at the designated stop line and only proceed when it is safe to do so. Unlike the Give Way sign, the Stop Sign requires a full stop, regardless of whether there’s approaching traffic.
This sign is commonly found at junctions where visibility is restricted, or where the right of way is complex, such as near railway crossings or intersections with multiple traffic flows. It plays a critical role in preventing accidents in high-risk areas by ensuring all vehicles pause before moving.
The Pedestrian Crossing sign features two black figures walking on a white background inside a red-bordered triangle. This sign warns drivers to slow down and be prepared to stop for pedestrians crossing the road ahead. It's especially important in areas with high foot traffic.
The Slippery Road sign, a red-bordered triangle featuring a car and skid marks, warns drivers that conditions ahead may make the road surface hazardous. This could be due to rain, ice, oil spills, or other factors that reduce tyre grip. It’s not a sign you’ll see frequently, but when you do, it’s essential to adjust your driving style immediately.
Slippery conditions are particularly dangerous because they can cause your vehicle to skid or slide unexpectedly, even at low speeds. The warning is often placed on roads with sharp corners, steep gradients, or near water sources where weather can cause slick surfaces.
The Road Narrows sign is a triangular sign with a red border and two black lines that converge, warning drivers that the road ahead will become narrower. This could occur on one or both sides, depending on the design of the sign, and it often signals reduced space for vehicles.
This sign is especially common in rural areas or older urban roads where infrastructure may have tighter clearances. In some cases, it may indicate an approaching bridge or obstacle that restricts the road’s width.
The Roundabout Ahead sign is a red-bordered triangle with three black arrows forming a circular shape. It warns drivers of an approaching roundabout and signals the need to reduce speed, prepare to give way, and enter the roundabout when it’s safe to do so. This sign helps drivers anticipate the change in traffic flow and adjust accordingly.
Roundabouts are a key feature of UK roads, designed to keep traffic moving efficiently while reducing the risk of high-speed collisions. Approaching drivers must yield to traffic already on the roundabout, coming from the right.
The National Speed Limit sign is a simple yet important white circular sign with a black diagonal stripe. This sign indicates that the road's default speed limit applies, which varies depending on the type of road and vehicle category. It’s essential to know these limits as they are not explicitly displayed on the sign itself.
This sign is typically found on rural roads, motorways, and dual carriageways where there are no specific speed restrictions. It serves as a reminder for drivers to adjust their speed based on the road type and conditions.
The Road Works sign is a red-bordered triangle with an illustration of a man digging, indicating that road maintenance or construction is taking place ahead. This sign warns drivers to slow down and proceed cautiously, as the road layout may change, or temporary traffic management systems might be in place.
Road works can lead to narrower lanes, reduced speed limits, or the presence of construction vehicles, making it crucial for drivers to stay alert. Additional signage, such as temporary speed limits or lane closures, often accompanies the Road Works sign to provide further guidance.
The Low Bridge sign is a red-bordered triangle with a height restriction displayed in the centre, typically in both metric (metres) and imperial (feet and inches) measurements. This sign warns drivers, particularly those operating taller vehicles, that the clearance height of a bridge or overhead structure ahead is limited.
Low Bridge signs are critical for ensuring vehicles exceeding the height limit do not attempt to pass under the structure, which could result in severe damage, traffic disruption, and safety hazards.
The No Overtaking sign is a red-bordered circle featuring two cars, one black and one red, side by side. This sign prohibits drivers from overtaking other vehicles on the stretch of road ahead. It is typically used in areas where overtaking would be unsafe due to limited visibility, sharp bends, or oncoming traffic risks.
Ignoring this sign can lead to dangerous manoeuvres, increasing the likelihood of head-on collisions. It’s a legally enforceable restriction, meaning failure to comply could result in penalties.
Parking restriction signs vary in design but are typically rectangular with a blue or white background and specific instructions or symbols. They inform drivers about where and when parking is allowed or prohibited, often detailing time limits, permit requirements, or loading restrictions.
These signs are crucial for managing parking spaces in busy areas, ensuring turnover, and maintaining traffic flow. Ignoring them can result in fines or having your vehicle towed.
The Motorway Exit sign is a green rectangular sign with white text and arrows, providing drivers with advance notice of an approaching exit. It often displays the junction number, destination names, and distances, helping drivers navigate motorways safely and efficiently.
This sign is essential for preparing drivers to move into the correct lane in good time and avoid last-minute lane changes, which can be dangerous. Multiple versions of this sign may appear before an exit, counting down with chevrons on additional signs to indicate the distance left.
The Cycle Lane sign is typically a blue circular sign with a white bicycle symbol or a rectangular blue sign indicating a dedicated path for cyclists. It designates areas of the road or separate pathways reserved for bicycles, ensuring their safety and separating them from motor vehicle traffic.
Cycle lanes are often marked on the road with white lines, and in some cases, a solid white line means motor vehicles must not enter the lane during its operational hours. Shared pathways for cyclists and pedestrians are also indicated by specific signage, showing how the space is divided.
The School Zone sign is a red-bordered triangle with an illustration of two children walking, often accompanied by supplementary plates stating "School" or specific time restrictions. It warns drivers to slow down and stay alert, as children may be crossing the road or present in the area.
School Zone signs are usually placed near schools, playgrounds, or areas where children frequently travel. Drivers must exercise extra caution, particularly during school opening and closing times, when pedestrian traffic is at its peak.
The No Through Road sign is a rectangular sign, typically blue or white, with a red horizontal bar at the end of a "T" shape. It indicates that the road ahead does not connect to other routes and will terminate, requiring drivers to turn around or find an alternative path.
This sign is commonly seen in residential areas or business parks to alert drivers that the road does not provide access beyond a certain point. It helps prevent unnecessary detours and confusion.
The Bus Lane sign is a rectangular blue sign with a white bus symbol, often accompanied by a bicycle or taxi icon and operational times. It indicates a dedicated lane for buses, and in some cases, for cyclists and taxis during specified hours. Outside these hours, the lane may be open to all vehicles.
Bus lanes are designed to prioritise public transport, improve traffic flow, and reduce congestion in urban areas. Driving in a bus lane during restricted hours can result in fines and penalties, so it’s important to read the accompanying information carefully.
