Motorcycle Theory Test – Road Signs

Traffic signs are an important tool for all drivers and motorcycle riders on UK roads. Road signs vary in shape, colour and meaning.

Signs are used to provide orders, warnings and hazards or may provide road users with directions. Road signs come in many forms. We often see them on panels on the side of the road as letters or symbols or as road markings. Though they can be represented in other forms such as flashing beacons, bollards and traffic lights.

It’s essential that road signs convey their message as easily and clearly as soon as possible, which is why shapes and symbols are often used. Road signs must be easy to see, easy to understand so that a road user can act accordingly and in good time.

In order to pass the motorcycle theory test, you must understand the various sign shapes in their basic form. The shape of a sign represents whether it’s an order, a warning or for informational purposes. This method along with many symbols are used throughout the UK and Europe.

Road Signs Shapes and Colours

The shape and colour of a road sign will determine whether it is giving orders, warnings or information.

Circular road signs give orders. Signs with a red ring around them tell you what you must not do. An example is to not exceed a speed limit. Blue circular signs tell you what you must do. An example is a blue circular sign containing a white arrow tells you which way you must travel.

Triangular ROAD SIGNS

Triangular road signs provide road users with a warning. An example could be warning of a junction up ahead, or that the road narrows ahead.


Motorcycle theory test rectangular road signs

Rectangular ROAD SIGNS

Rectangular road signs vary in colour depending on their location. For example blue signs provide information and directions on motorways, green on dual carriageways and white signs provide directions on non-primary roads.


Road Signs Giving Orders

Signs giving orders are categorised either by:

  • Prohibitory – signs telling you what you must not do
  • Mandatory – signs telling you what you must do

Prohibitory signs

Prohibitory signs can be recognised due to being a circular white sign with a red border. These signs can contain symbols, words or figures, or there may be a combination. Typical prohibitory signs include:

Motorcycle theory test - order signs with figures
Prohibitory signs with figures – speed limit signs (must not exceed 30 mph)
Motorcycle theory test - order signs with symbols
Prohibitory signs with symbols (no overtaking)
Motorcycle theory test - signs with symbols and figures
Prohibitory signs with symbols and figures (no goods vehicles exceeding 7.5 ton)

Most prohibitory road signs are circular with a red border such as the examples above, the exception to this is:

Motorcycle theory test prohibitory no entry sign
Prohibitory no entry road sign – must not enter
Motorcycle theory test prohibitory bus lane sign
Prohibitory bus lane sign – must not enter bus lane within times shown
Motorcycle theory test prohibitory national speed limit sign
Prohibitory national speed limit – must not exceed the speed limit for this road type
Motorcycle theory test prohibitory 'Clearway' must not stop sign
Prohibitory ‘Clearway’ must not stop at any time sign


Mandatory Signs

Mandatory road signs are usually a blue circular sign with white symbols.

Motorcycle theory test - Mandatory blue signs
Mandatory mini roundabout sign – you must give way to traffic approaching from the right
Motorcycle theory test - Mandatory blue signs
Mandatory sign – you must proceed in direction indicated on sign
Motorcycle theory test - Mandatory blue signs
Mandatory 30 mph sign – you must drive at no less than 30 mph


Other than the typical circular blue signs, other mandatory signs are:

Mandatory stop sign

Mandatory STOP octagonal signs are usually located at junctions with limited visibility. Stop signs are always accompanied with a stop line marked across your lane, separating your lane from the junction. It is a legal requirement for motorists to stop at the line before proceeding – even if it appears safe to proceed without the need to stop.


Mandatory School Crossing stop signSchool children ‘STOP’ signs are mandatory and are usually carried by crossing patrols along zebra crossings. Often referred to as a ‘lollipop’, it is a legal requirement to stop your vehicle when displayed by a crossing patrol.


Motorcycle theory test prohibitory give way signThe unique upside down triangle of the ‘Give way’ sign uses this form to differentiate from other signs so that they can be understood even if the writing is obscured. Often located at junctions, though on some quiet roads, only the road markings may be found.  You must give way to traffic on the major road.

Warning Road Signs

Warning signs are most often triangular in shape with a white background and red border. They are placed in locations to provide road users of an impending hazard. Examples of warning road signs are:

Motorcycle theory test warning road sign - junctions

Junction warning signs will inform the motorist which type of junction is ahead. T-junction, crossroad, staggered junctions, side roads, side roads on a bend and crossroads. The line, or ‘road’ which has the wider line on the sign signifies who has priority.


Motorcycle theory test warning road sign - chevron signsOther warning road signs not represented by the equilateral triangle with a red border are chevron signs. Placed on or before sharp corners, they are used to warning drivers. They show direction changes to the left or right.


Direction Road Signs

These road signs help you find the place you’re looking for such as a town or city. As well as direction signs, information signs are also used to indicate places of interest. The types of road signs vary depending on location and meaning:

Motorcycle theory test motorway road signsRoad signs used on motorways are blue with white letters and a blue border.


Motorcycle theory test primary route road signsPrimary routes with the exception of motorways have green signs with white letters and a green border. Route numbers are shown in yellow letters.


Motorcycle theory test other route road signsOther routes use white road signs with black letters and a blue or black border.


Motorcycle theory test information tourist road signsTourists information signs are brown in colour with white symbols and letters with a brown border. They point motorists in the general direction of places of interest such as a zoo or camping site.
