Theory Test Topic: Road and traffic signs

What are road and traffic signs

The eighth topic from the theory test is road and traffic signs. Whilst all of the topics we’ve covered (and are going to cover) are vital in helping you become a safe driver, road and traffic signs probably take the cake in terms of importance. Once you get behind the wheel in your lessons, you’ll need to be able to identify road and traffic signs and know what action(s) you need to take. Otherwise, you could end up endangering yourself and other road users.

To help make things easier for you, we’ve broken down all of the road and traffic signs into subsections. Make your way through each section carefully—we’ve included a link to the DVSA’s official Know Your Traffic Signs PDF at the end which you will need to make your way through in order to get to grips with all of the road and traffic signs that you might encounter when behind the wheel. Once you’ve done that, you’ll put your memory skills to the test with our mock tests further below!

When it comes to revising for the theory test, start with the Highway Code, which provides vital road information and rules. We advise buying resources like the official DVSA handbook or the AA theory test book. They both contain official DVSA questions with answers. Revise them thoroughly—they could show up on your test.

✓ Circular signs

Circular road signs are mandatory instructions that all drivers must follow. If you disobey them, then you could potentially end up with a fine and penalty points. They come in two different colours: blue and red.

Blue circles

If you spot a blue circular sign on the road, it’s telling you to do something. They’re commonly used for minimum speed limits, showing drivers which direction to go in and indicating which road user can use a specific route, e.g., cyclists and pedestrians.

Red circles

Red circular signs, or rings, are the exact opposite of their blue counterparts—they’re telling you what you must not do, e.g., do not exceed 30mph, or, no vehicles over the height shown may proceed.

✓ Triangular signs

Red triangles warn road users that there are potential hazards on the road ahead, e.g., traffic signals, a junction on a bend, or two-way traffic. Once you spot these signs, you’ll know that you’ll need to potentially alter your speed, or change lanes.

You might spot the occasional red triangle sign with a white sign below containing text—this is simply there to provide further elaboration about the potential hazard, e.g., roadworks are at an end. You might also notice inverted triangles on the road. They’re also there to provide warnings. The most recognisable inverted triangle sign you’ll probably see on the road is ‘Give Way’.

✓ Rectangular signs

Rectangular signs offer up information to road users. This can range from directions to primary, non-primary or local routes, tourist destinations or even traffic routes during roadworks. As with circular signs, they come in different colours to signify what type of information they’re offering.

Blue rectangles

Blue rectangles (with a white border) play different roles depending on what type of road you’re on. If you’re on the motorway, blue rectangular signs offer you directions, e.g., telling you which lanes to use on the approach to a junction, or letting you know when a roundabout is ahead.

Appropriate lanes for turning road sign Directions from junction ahead road sign Motorway junction road sign
Appropriate lanes for turning movements at junction ahead Directions from junction ahead Motorway to motorway junction with a roundabout

If you spot blue rectangular signs on any other road type, however, they’ll be offering you general information about the road ahead, e.g., telling you that a road is one-way, that there are bus/cycle lanes next to you, or even where you can find parking spaces.

Green rectangles

Green rectangular signs are direction signs that are based on primary routes (mostly A roads). You’ll see these A roads highlighted in a bold yellow colour. Additional details might include white rectangles with black text for non-primary routes and a blue rectangle for alternative routes (for cyclists) or directions to a nearby motorway.

Red rectangles

As with red triangular signs, red rectangles are there to either warn road users of a potential hazard up ahead, or to instruct them to take a certain action. They will come with a written warning, e.g., ‘reduce speed now’.

White rectangles

White rectangular signs are typically used for direction signs on non-primary routes, e.g., parking and local facilities. They are also used in conjunction with warning signs in order to give road users more information.

Brown rectangles

Brown rectangles are used to indicate tourist destinations to road users—telling them which junction to turn into or how far away the destination is. These signs are usually separate from main direction signs. They’ll usually come with the name of the destination and a picture that indicates what kind of tourist attraction it is.

Yellow rectangles

Yellow rectangles are commonly used to provide road users with information about current or future roadworks—indicating where the roadworks are taking place, when work begins and what delays might be like. Road users will then know to use alternative routes, or to give themselves extra time when travelling on these routes.

✓ Exceptions

As with every rule in life, there are a few exceptions to the shape and colour rules that we’ve discussed so far with road signs. These are often used so that a sign is so distinctive that a motorist will have no doubt over its meaning, such as the red octagonal stop sign.

Stop before crossing the line and check the way is clear before entering road The national speed limit applies here Speed limit sign for tram drivers (km per hour) No stopping, not even to pick up or drop off passengers

✓ Traffic lights

Traffic lights are very easy to understand. Their sequence is as follows:

  • Red (stop)
  • Red and amber (prepare to move)
  • Green (go)
  • Amber (stop unless it isn’t safe to do so)

If you spot a green arrow light (otherwise known as a filter) instead of the standard green light, this means that you should move in the direction it tells you to. If there’s a filter light and a standard green light, it means that you can go in the direction of the arrow (if it’s lit up), even if the main light is on red. Obviously, you have to make sure that oncoming traffic has stopped, or that the way is clear, before moving.

You might also spot a set of twin red traffic lights, usually found at level crossings and bridges, which indicate that you need to come to a stop when they’re flashing.

Know your traffic signs

Though we’ve walked you through the different shapes and colours of road signs that you’ll encounter when behind the wheel, that’s only really the tip of the iceberg. Before you proceed onto our mock tests (let alone go in for your theory test), you will need to make your way through the ‘Know Your Traffic Signs PDF‘. This walks you through all of the road and traffic signs that you might come across when driving.

Once you’re done with that, try out our mock tests below. If you want to really make sure that you’ve memorised the signs, try printing some out and getting someone to test you!

Case studies

It’s not enough to just have this theory test knowledge in your head, you also need to be able to apply it to real-life situations. That’s why the DVSA include a video case study at the end of the multiple-choice section. You’ll watch this clip and then answer three questions about it—figuring out what course of action the driver should take or how they should react to a situation. Below, we’ve created five written case studies involving road and traffic signs, to give you an idea of what to expect.
