What they meanWhat to do - if stationaryWhat to do - if approaching
Traffic Lights for Drivers and Riders The green light means that you may move across the junction or crossing provided that it is safe to do so. Go if way is clear giving way to pedestrians still crossing. If turning left or right give way to pedestrians crossing at the same time. Cross carefully. Do not accelerate before the lights. Before you enter a junction check right and left and right again. Give way to pedestrians who are crossing at the same time.
Traffic Lights for Drivers and Riders The amber light always follows the green light. You must stop unless you are so close to the junction or crossing that to do so suddenly might cause an accident. Stop behind the 'Stop' line. Slow down and stop.
Traffic Lights for Drivers and Riders The red light always follows the amber lights. You must stop behind the 'stop' line on the roadway. Stay behind the 'Stop' line.

Slow down and do not cross until lights have changed to green.

'Tunnel area' and expressway signals

Special signals are used in 'Tunnel areas' and expressways. In normal conditions they are switched off or show a green downward arrow or a green light. In dangerous conditions, amber lights flash and the signal shows what action must be taken.

In most tunnels or on expressways the signals are overhead, one applying to each lane. In some places the signal is on the roadside, central reservation or on the tunnel wall alongside the traffic lane or slip road to which it applies.

Illustrated are lane control signs usually mounted on gantries above the road and signals mounted on the roof of the tunnel.

These signals are for safety. Always act on them - danger may be present even if you cannot see the reason.

Do not change lanes suddenly and do not move over unless it is safe to do so. If before you can safely leave the lane, you reach the danger or obstruction, stop and wait in that lane until the open lane is clear. dot2.gif (807 bytes)
