Signals to other road users
Signals used to other road users, including direction indicator signals, brake light signals, reversing light signals and arm signals.
Direction indicator signals
I intend to move out to the right or turn right
I intend to move in to the left or turn left or stop on the left
These signals should not be used except for the purpose described.
Brake light signals
I am applying the brakes
This signal should not be used except for the purpose described.
Reversing light signals
I intend to reverse
This signal should not be used except for the purpose described.
Arm signals
For use when direction indicator signals are not used, or when necessary to reinforce direction indicator signals and stop lights. Also for use by pedal cyclists and those in charge of horses.
I intend to move in to the left or turn left
I intend to move out to the right or turn right
I intend to slow down or stop
I intend to move in to the left or turn left
I intend to move out to the right or turn right
I intend to slow down or stop
These signals should not be used except for the purpose described.
Hazard lights
I am temporarily obstructing traffic or warning of a hazard or obstruction ahead (see Rule 116)
Signals to Other Road Users: What You Need to Know for the Theory Test
Drivers use indicators, brake lights, reversing lights, arm signals and hazard lights to communicate their intentions. The key is understanding what each signal means and when it should be used.
Show your intended movement
Use the appropriate indicator to show that you intend to move left or right, turn, or stop on the left. Signal clearly and at the appropriate time.
A signal does not give you priority
An indicator tells others what you intend to do. It does not automatically give you the right to move. Check mirrors, position and surrounding traffic before changing direction or lane.
What is a common indicator mistake?
Do not treat an indicator as permission to move. The correct sequence is to observe the road, make sure the movement is safe, then signal and act appropriately.
Show that you are braking
Brake lights warn following road users that you are applying the brakes. They are a communication signal, not a substitute for safe following distance or observation.
React to brake lights early
If the vehicle ahead shows brake lights, assess the developing situation and be prepared to reduce your speed or stop if necessary.
Brake lights vs indicators
Brake lights communicate braking. Direction indicators communicate an intended change of direction or movement. Do not confuse the two.
Indicate an intention to reverse
Reversing lights indicate that a vehicle intends to reverse. Treat this as a warning and take particular care around the vehicle.
Expect hidden movement
A reversing vehicle can have significant blind spots. Do not pass close behind it or assume the driver has seen you.
What do reversing lights mean?
The key answer is simple: the driver intends to reverse. Do not interpret the lights as permission for you to pass behind the vehicle.
Know the three basic meanings
Arm signals can communicate an intention to move or turn left, move or turn right, or slow down or stop. They may be used when indicators are not used or to reinforce other signals.
Look at the direction of the arm
For Theory Test questions, focus on what the arm position communicates: left movement, right movement, or slowing and stopping. Cyclists and people in charge of horses may also use these signals.
Why are arm signals tested?
Questions may show an arm position and ask what the person intends to do. Learn the three core meanings rather than relying on the vehicle's indicators.
Warn about a temporary hazard
Hazard warning lights can be used to warn other road users of a hazard or obstruction, including when traffic is temporarily obstructed.
Do not confuse hazards with indicators
Indicators communicate a specific intended direction or movement. Hazard lights communicate a warning about a hazard or temporary obstruction.
The signal must match the situation
Theory Test questions often test whether you understand why a signal is being used, not simply which lights are visible.
Remember Before the Theory Test
Don't Mix These Up on the Theory Test
Signals can look similar or appear together, but each one communicates a different message.
Signals to Other Road Users: Theory Test FAQ
What do direction indicators mean?
They show an intention to move out to the right, move in to the left, turn, or stop on the left. Remember that an indicator communicates intention and does not give you priority.
Do indicators give a driver priority?
No. An indicator tells other road users what the driver intends to do. The driver must still check that the manoeuvre is safe and obey any applicable priority rules.
What do brake lights tell other road users?
Brake lights show that the vehicle is applying its brakes. If you see them on the vehicle ahead, assess the situation and be prepared to slow or stop.
What do reversing lights mean?
They indicate that a vehicle intends to reverse. Take particular care because the driver may have limited visibility behind the vehicle.
What are the three main arm signals drivers should know?
The core meanings are: moving or turning left, moving or turning right, and slowing down or stopping. These signals are also relevant to cyclists and people in charge of horses.
When can arm signals be used?
They can be used when direction indicators are not used, or when necessary to reinforce direction indicators or stop lights. They are also used by pedal cyclists and those in charge of horses.
What do hazard warning lights mean?
They warn other road users about a hazard or obstruction, including when a vehicle is temporarily obstructing traffic. They are different from ordinary direction indicators.
What is the difference between hazard lights and indicators?
Direction indicators communicate a specific intended movement or direction. Hazard lights warn other road users about a hazard or temporary obstruction.
Can an indicator be used as a signal that it is safe to move?
No. A signal only communicates an intention. You must still check mirrors, surrounding traffic, road position and any other hazards before moving.
What signal should I remember for a vehicle that intends to reverse?
Look for reversing lights and treat them as a warning that the vehicle intends to reverse. Stay clear of its path and do not assume the driver can see you.
