Traffic lights are signalling devices most commonly found positioned on roads, junction intersections and pedestrian crossings to control the flow of traffic. They are also found in other areas, predominantly on bridges, train crossings/stations, buildings and more. 🚦
They are installed globally and are instantly recognisable by always using the three standard colours of red, amber and green. Without these simple yet effective lights, our roads would be in utter chaos as every year the roads get busier and busier with more traffic flowing through them. The use of technology monitoring and maintaining the flow of traffic through lights are a necessity in our everyday lives. 🚨
The three most common traffic lights you are likely to find on our roads are:
⚡ Red/Amber/Green Traffic Lights.
These lights are what you will see daily on our roads as they help ease the flow of traffic. Globally the red light means ‘stop’ the amber light means ‘caution’ and the green light means ‘go’. They assign the right of way for the road user and help to ensure our busy roads run as smoothly as possible.
⚡ Walking/Standing Man Traffic Lights.
These lights are usually indicators for pedestrians; an indication when it is not safe to cross a road by lighting up a red standing man, or it is safe to cross a road by lighting up with a green walking man.
The same notion of colours is seen here, red to stop and green to go.
⚡ Wig-Wag Traffic Lights.
Wig-wag lights are usually found in colours amber-amber or red-red and are generally used on level bridge crossings and other such areas where there is a need to stop ordinary traffic flow.
