Why Do Some Traffic Signals Flash Red and Some Flash Yellow Amber in India?
Ever wondered, why do some traffic signals always flash red and others flash yellow/amber, especially at night? What do these flashing signals with different color codes mean? Do these blinking signals have any meaning?
If you have every stood at a cross road when the signals were working (but in standby mode on a continuous blink), like when a VIP was passing by or late at night when there is less traffic on the road, you may have seen that some traffic signals flash red and others flash yellow/amber.
They are specifically set to flash a specific color based on the type of road and based on the purpose of having the signal.
You will notice at a cross road, that the Arterial Road or Main Road or Highway will always have the Amber Light Flashing. A smaller road or a lane will have a Red Light Flashing. This is designed to allow the Arterial Road or Highway Traffic to have priority over the smaller road or the less priority road. A VIP Route or larger width road will always have traffic priority over a smaller road or lane.
What does a traffic signal blinking red indicate?
A red blinking signal indicates that the motorist must come to a complete stop and then proceed. They must yield or give way to the traffic coming from the other intersecting road.
What does a traffic signal blinking yellow/amber indicate?
A yellow blinking signal indicates that the motorist must come slow down and then proceed after checking if the road is clear. They get priority over the traffic coming from the other intersecting road.
