Light signals controlling traffic.

All of the signals are important. Don't just study the common ones.

Some of these signals you will probably not come across too often. You do however need to know them because when you see them there will be no time to grab a copy of the highway code and even less time to get online.

Traffic Light Signals

Traffic Light Signals
	RED means 'Stop'. Wait behind the stop line on the carriageway			RED AND AMBER also means 'Stop'. Do not pass through or start until GREEN shows				A GREEN ARROW may be provided in addition to the full green signal if movement in a certain direction is allowed before or after the full green phase. If the way is clear you may go but only in the direction shown by the arrow. You may do this whatever other lights may be showing. White light signals may be provided for trams
	GREEN 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			AMBER means 'Stop' at the stopline. You may go on only if the AMBER appears after you have crossed the stop line or are so close to it that to pull up might cause an accident
Flashing Red Lights
Alternately flashing red lights mean YOU MUST STOP. At level crossings, lifting bridges, airfields, fire stations, etc
