If you’re preparing for the theory test or starting driving lessons, road signs can seem overwhelming at first. This guide will help you understand the basics.
We’ll cover the most common signs, what they mean, and how to spot patterns — so you feel more confident on the road and in your test.
Why road signs matter
Road signs keep traffic safe and predictable. You’ll need to:
- Recognise them quickly while driving
- Understand what actions they tell you to take
- Answer questions about them in the theory test
The DVSA includes dozens of questions about signs. This is one of the most tested areas.
The 3 basic shapes
Understanding the shapes helps you guess the meaning even before you read the detail.
1. Circles
Tell you what you must or must not do.
- Red circle = prohibition (e.g. no entry)
- Blue circle = instruction (e.g. turn left)
2. Triangles
Warn you about something ahead.
- Red border, point upwards = warning signs
- Example: sharp bend, slippery road
3. Rectangles
Give information.
- Blue background = motorway
- Green background = primary routes
- White background = local directions or temporary signs
Common UK road signs explained
Speed limit signs
- Red circle with number: maximum speed allowed
- No red circle: advisory speed limit only
No entry
- Red circle with a white horizontal bar
- Do not enter from that direction
Give way
- White triangle with red border, point down
- Slow down and prepare to stop if needed
Stop
- Red octagon
- You must stop, even if the road looks clear
Mini roundabout
- Blue circle with 3 white arrows
- Give way to the right, proceed clockwise
Pedestrian crossing
- Blue rectangle with white symbol
- Slow down and prepare to stop for pedestrians
Temporary signs
Usually yellow with black text. Found near roadworks or diversions. Always follow them, even if permanent signs say something else.
Signs with symbols
Many signs use pictures instead of words. Learn what they mean:
- Car symbol = applies to cars
- Lorry symbol = applies to heavy goods vehicles
- Bicycle symbol = applies to cyclists
The theory test includes these symbols often, so memorise them early.
Tips for learning road signs
- Use the official Highway Code
- Practise with a theory test app
- Test yourself with flashcards
- Ask your instructor during lessons
- Look at signs while walking or as a passenger
Repetition helps. Start with 10 signs per day and build up.
FAQs: Theory Test Help for Learner Drivers
How many road sign questions are on the theory test?
Usually 10 to 15. They may appear in both the multiple choice and hazard perception sections.
Can I take my theory test before I start lessons?
Yes. But many learners find it easier to pass the theory after a few driving lessons.
What happens if I ignore a road sign during the practical test?
You could get a minor or major fault, depending on the sign and situation.
Are temporary signs more important than permanent ones?
Yes. Always follow temporary signs. They override permanent signs if they conflict.
Do I need to memorise every sign?
No. But you should recognise all the common signs and understand the key shapes, colours, and meanings.
