Traffic lights and signals
This section builds on Section 6, which covers traffic signs and road markings.
This section covers two general forms of traffic signals:
- traffic lights, which direct the flow of traffic, and
- signals given by motorists and cyclists to indicate their intent.
These include lights controlling junctions and pedestrian crossings.
|
A red light means 'stop'. If the light is red as you approach it, you must not go beyond the stop line at that light or, if there is no stop line, beyond the light.
A green light means you may go on if the way is clear. Take special care if you intend to turn left or right and give way to pedestrians who are crossing. A green light is not a right of way, it is a licence to proceed with caution.
|
An amber light means that you must not go beyond the stop line or, if there is no stop line, beyond the light. However, you may go on if you are so close to the line or the light when the amber light first appears that stopping would be dangerous.
A green arrow (also known as a filter light) means that you may move on in the direction of the arrow, assuming it is safe and the way is clear, even if a red light is also showing.
If you wish to turn right at a set of traffic lights that has an arrow to the right, drive into the junction when you see a green light, taking care not to block any oncoming traffic. Then, when it is safe, finish your turn. You should only wait for the filter arrow for turning right when you are in the junction and if it would be dangerous to finish your turn before the filter light appears.
A flashing amber arrow pointing left can appear at a junction with another road.
It means that you may move on past the traffic light, but only if you first give way to traffic already coming through the junction on the other road.

Remember that a flashing amber light at a pelican crossing means you must yield to pedestrians. See Section 18, on pedestrian lights.

Cycle track lights
- A red light showing a figure of a cyclist means that the cyclist must stop at the traffic light.
- A green light showing a figure of a cyclist means the cyclist may move beyond the light as long as this does not put other road users in danger.
- A flashing green light or an amber light showing a figure of a cyclist means the cyclist may not cross the road unless they had started crossing when there was a steady green light showing a figure of a cyclist.

Signals by motorists and cyclists
A motorist must always signal before they change their course. This means
signalling clearly and in good time before:
- moving off,
- turning right or left,
- changing lanes,
- overtaking,
- Slowing down or,
- stopping.
Signals are an indication of intent - they do not confer a right of way. The law requires you to signal your intention of doing things on the road. This means signalling properly before moving off, turning right or left, changing lanes, overtaking, slowing down or stopping. You must signal clearly and in good time. If you are not certain that your direction indicators or stop lamps, for whatever reason, are giving an adequate signal, use clear decisive hand signals as well.
Hand signals
Make sure that any signals you use help rather than confuse other road users.
If you are using hand signals, be familiar with the images below showing the
signals drivers and cyclists must give to other traffic and to someone directing
traffic.
The signals for the cyclist also apply to motorcyclists and people in charge
of horse-drawn vehicles and/of agricultural machinery not fitted with indicators.
The following are the hand signals to be used:

The signals for the cyclist apply also to a motorcyclist and to a person in chagre of a horse drawn vehicle.
