With hundreds of road signs used across the UK, it’s unlikely that you’ll recognise every single one. Whether you’re looking to refresh your knowledge or preparing to get on the road for the first time, understanding the different types of road signs in the Highway Code can help you travel more safely and confidently.
Most UK road signs can be identified by their shape, falling into one of three main categories:
- Regulatory signs (circles)
- Warning signs (triangles)
- Direction and information signs (rectangles)
In this guide, we’ll look at some of the most common UK road signs, what they mean, and how they differ from each other.

How Many Road Signs Are There in the UK?
The UK Highway Code currently illustrates around 140 different types of road signs. These cover everything from speed limits and restrictions to road hazards and direction signs.
However, this doesn’t include regional variations, temporary signage, or combinations of multiple signs displayed together.
Trying to remember every road sign can feel overwhelming, but you don’t need to memorise them all at once. You’ll come across many of the same signs on a day-to-day basis, while others are only used in specific locations or situations.
What Are the Main Types of Road Signs in the UK?
Road signs all serve different purposes, from warning you about potential hazards to providing directions and instructions. One of the easiest ways to recognise what a sign is telling you is by its shape.
The three main types are circular, triangular, and rectangular signs.
Circular Signs
Circular signs are generally referred to as regulatory signs. They tell road users what they must or must not do.
Ignoring certain regulatory signs can result in fines, penalty points on your license, or more serious penalties.
There are three main types of circular road signs:
Red circular signs tell you what you must not do. Common examples include No Entry, No Overtaking, and speed limit signs.
Blue circular signs tell you what you must do. You’ll often see them giving instructions such as Keep Left, Keep Right, and Mini Roundabout.
National Speed Limit signs are also circular, but have their own distinctive design. They show that the national speed limit applies to the road you’re currently travelling on.

Triangular Signs
Triangular signs are used to provide a warning of potential hazards ahead. They give you time to slow down and take greater care before reaching the affected area.
Most warning signs have a white background with a red border, making them easy to recognise. Many also use RA1 or RA2 reflective sheeting to improve visibility, especially in low-light conditions.
Triangular signs can warn you about:
- Changes in road conditions, such as road humps
- Junctions and roundabouts ahead
- Pedestrian and animal crossings
- Sharp bends and uneven surfaces
- Roadworks
When you see a warning sign, take extra care and pay attention to the road ahead. Depending on the hazard, you may need to slow down or be prepared to stop.
Give Way signs are also triangular, but they’re displayed upside down. This helps distinguish them from standard warning signs and shows that you must give priority to traffic on the road you’re joining.

Rectangular Signs
Rectangular signs are mainly used as information and direction signs, helping drivers find their way and understand the road ahead. The colour of the sign can often tell you more about the route you’re travelling on.
Green Panels
Green road signs are used on primary routes. They provide directions to towns, cities, and other destinations along the UK’s main A-road network.
Blue Panels
Rectangular signs with blue backgrounds are most commonly associated with motorways. They provide information about routes, junctions, exits, and motorway services.
White Panels
White signs are commonly found on local and non-primary routes. They provide directions to nearby towns, villages, and other local destinations.
Brown Panels
Brown road signs direct road users towards tourist attractions and destinations. They commonly direct towards historic sites, visitor attractions, and other places of interest.

Temporary Road Signs & Roadworks
Not every road sign is permanently installed. Temporary signs are used when normal road conditions have changed, particularly during roadworks and other traffic management situations.
You might see temporary signs warning of roadworks ahead, lane closures, diversions, temporary speed limits, or changes to the road layout. Temporary signs help manage traffic flow and guide road users safely through changing road conditions.
Many temporary traffic signs are designed to be portable, making them easier to install and remove as required. Depending on the situation, they may be mounted on portable frames, posts, or traffic cones.
Clear temporary signage plays an important role in helping drivers and other road users safely navigate changing road conditions.
What Do Road Sign Colours Mean?
The colour of a sign can give you a quick idea of the type of information it provides. While there are some exceptions, the most common colours generally mean:
- Red: Restrictions, prohibitions, and warnings
- Blue: Mandatory instructions and motorway information
- Green: Directions along primary routes
- Brown: Tourist attractions and destinations
- Yellow: Temporary traffic management and roadworks
- White: General information and directions
Knowing what these colours usually mean can help you understand the purpose of a sign before you’ve had time to read the text or symbol.
Are All UK Road Signs the Same?
Most road signs follow the same designs and rules across the UK, but there are some variations depending on where you’re travelling.
For example, bilingual signs are commonly used in Wales, displaying information in both Welsh and English. Local authorities may also use signs for specific areas, such as controlled zones, parking restrictions, or local facilities.
Temporary signage can also differ from permanent signs. They’re used for situations such as roadworks, diversions, and temporary traffic management.
You’ll also come across signs on private roads, car parks, and commercial sites that aren’t commonly used on public roads. These can provide instructions and information specific to the site.
Despite these differences, the basic shapes, colours, and symbols used on UK road signs remain familiar, making them easier for road users to understand.
FAQs
Circular signs are generally used to give instructions or restrictions. Red circles usually tell you what you must not do, while blue circles tell you what you must do.
Triangular signs warn road users about potential hazards ahead. These can include sharp bends, junctions, pedestrian crossings, roadworks, and changes in road conditions.
Rectangular signs are mainly used to provide information and directions. Their colour can help you understand the type of route or information being shown.
No. You’ll regularly come across many of the same signs during everyday journeys. Others are only used in specific locations or situations, so you’ll become familiar with them over time.
Most signs follow the same standard designs across the UK. However, there are regional variations, including bilingual signs in Wales, as well as temporary and location-specific signage.
Round Up
There are plenty of road signs to recognise, but understanding the basics makes things much easier. Their shapes, colours, and symbols can often give you a good idea of what they’re trying to tell you.
From warning you about hazards ahead to giving directions and important instructions, road signs are there to help keep everyone moving safely.
