‘Countdown’ markers at exit from motorway (each bar represents 100 yards to the exit). Green-backed markers may be used on primary routes and white-backed markers with black bars on other routes. At approaches to concealed level crossings white-backed markers with red bars may be used. Although these will be erected at equal distances the bars do not represent 100 yard intervals.

Information Signs UK: What You Need to Know for the Theory Test

Information signs give drivers advance warning, explain road conditions and restrictions, identify facilities and show how traffic should move through specific areas or junctions.

PARKING & ZONES

Recognise controlled areas

Information signs can mark the entrance to or end of a controlled parking zone or congestion charging zone. Read the sign before continuing into the area.

HOW TO APPLY

Look for restrictions ahead

An advance warning sign gives you time to understand a restriction or prohibition before you reach it. Do not wait until the last moment to react.

THEORY TEST

What does an HOV lane mean?

HOV means high occupancy vehicle. The sign identifies a lane reserved for vehicles meeting the displayed occupancy or vehicle-use requirements.

BUS LANES

Check who may use the lane

Information signs can warn of a bus lane ahead and may indicate other permitted users, such as pedal cycles or taxis. Always check the sign and road markings.

HOW TO APPLY

Follow lane information early

Where signs show appropriate traffic lanes at a junction, choose your lane in good time and follow the route indicated by the markings and signs.

THEORY TEST

Who has priority when lanes merge?

Some information signs specifically show which traffic has priority when lanes or slip roads join. Do not assume the joining vehicle automatically has priority.

MOTORWAYS

Know the start and end signs

Specific information signs identify where a motorway begins and where it ends. The start sign also marks the point from which motorway regulations apply.

HOW TO APPLY

Know when motorway rules begin

Do not treat a motorway entrance as simply another junction. Once the motorway start sign is reached, the specific motorway rules apply.

THEORY TEST

What do countdown markers tell you?

Motorway exit countdown markers show that an exit is approaching. Treat them as advance information and prepare for the junction safely.

PRIORITY

Read priority signs carefully

Some rectangular information signs show that traffic has priority over oncoming vehicles or that main-carriageway traffic has priority over joining traffic.

HOW TO APPLY

Do not rely on assumptions

At merges and narrow sections, use the displayed priority information. Check mirrors, position safely and give way where the signs require it.

THEORY TEST

What does a no-through-road sign mean?

A no-through-road sign means the road does not provide a through route for vehicles. It can be useful when choosing whether a road will lead to your intended destination.

Site Editorial Note: This is an editorial Theory Test revision summary, not a replacement for the official Highway Code.

Remember Before the Theory Test

MOTORWAY START The motorway start sign marks the point from which motorway regulations apply.
MOTORWAY END A separate sign marks the end of a motorway. Be alert for the change in road environment and rules.
BUS LANE Check which vehicles are permitted to use a bus lane. Signs and road markings provide the information.
HOV LANE HOV means high occupancy vehicle. Follow the displayed conditions for using the lane.
PRIORITY Some signs show that main-carriageway traffic has priority over joining traffic. Read the arrows carefully.
COUNTDOWN Countdown markers give advance warning that a motorway exit is approaching.
NO THROUGH ROAD The road does not provide a through route for vehicles.
CONTROLLED ZONE A zone-entry sign means specific controls or restrictions apply within the signed area.
TRAFFIC LANES Use advance lane information to choose the correct lane before reaching a junction.
CAMERA SIGN Some areas use cameras to enforce traffic regulations. Take the displayed restrictions seriously.

Don't Mix These Up on the Theory Test

Information signs can look similar while giving completely different instructions. Pay particular attention to motorway signs, priority information, lanes and controlled zones.

Motorway start
Motorway regulations begin
vs
Motorway end
Remember
The start sign marks where motorway regulations apply; the end sign marks where the motorway finishes.
Bus lane
Specific permitted users
vs
HOV lane
Remember
A bus lane is based on the displayed permitted vehicle types; an HOV lane is based on the applicable high-occupancy requirement.
Traffic has priority
Priority over oncoming traffic
vs
Joining traffic priority
Remember
Read the direction of the arrows. The sign may show priority between opposing traffic or between lanes joining the main carriageway.
Controlled parking zone
Parking controls
vs
Congestion charging zone
Remember
Both are controlled areas, but they refer to different types of traffic or parking controls. Do not treat the signs as interchangeable.
Countdown markers
Exit approaching
vs
Junction information
Remember
Countdown markers give advance warning of an approaching motorway exit; they do not replace the actual junction information.
No through road
No vehicle through route
vs
Road restriction ahead
Remember
A no-through-road sign tells you about the road layout. An advance restriction sign warns about a specific restriction or prohibition ahead.

Information Signs UK: Theory Test FAQ

What are information signs used for?

They provide useful information about road layouts, traffic lanes, restrictions, facilities, priorities, motorway conditions and other features that help drivers understand the road ahead.

What does the motorway start sign mean?

It identifies the start of a motorway and marks the point from which motorway regulations apply.

What does an HOV lane sign mean?

HOV means high occupancy vehicle. The lane is designated for vehicles that meet the applicable occupancy or vehicle-use conditions shown by the signs and markings.

What should drivers know about bus lane signs?

Bus lane signs provide information about a lane reserved for buses and may identify other permitted users. Always check the accompanying signs and road markings.

What do motorway countdown markers mean?

They give advance warning that a motorway exit is approaching. Use the information to prepare for the junction safely and in good time.

What does a no-through-road sign mean?

It means the road does not provide a through route for vehicles. The sign can help you avoid entering a road that will not lead through to another road.

What does a priority information sign show?

Some information signs show which traffic has priority at a junction or where traffic lanes merge. Follow the direction of the arrows shown on the sign.

What is a controlled parking zone?

It is an area where specific parking controls apply. An entry sign warns drivers that they are entering the controlled zone, while another sign marks its end.

What does a congestion charging zone sign mean?

It identifies the entrance to an area where congestion charging controls apply. The sign gives drivers advance information that they are entering the relevant zone.

What does a camera enforcement sign mean?

It indicates an area where cameras are used to enforce traffic regulations. Drivers should pay close attention to the applicable signs, markings and restrictions.

What should I remember about information signs for the Theory Test?

Focus on what each sign is telling you: where a restriction starts or ends, who has priority, which lane to use, what type of route or facility is ahead, and when motorway rules apply.
