Traffic lights alternate the right of way accorded to users by displaying lights of a standard colour (red, amber (yellow), and green) following a universal colour code. In the typical sequence of colour phases:

The green light allows traffic to proceed in the direction denoted, if it is safe to do so and there is room on the other side of the intersection.

The amber (yellow) light warns that the signal is about to change to red. In a number of countries – among them the United Kingdom – a phase during which red and yellow are displayed together indicates that the signal is about to change to green.Actions required by drivers on a yellow light vary, with some jurisdictions requiring drivers to stop if it is safe to do so, and others allowing drivers to go through the intersection if safe to do so.

A flashing amber indication is a warning signal. In the United Kingdom, a flashing amber light is used only at pelican crossings, in place of the combined red–amber signal, and indicates that drivers may pass if no pedestrians are on the crossing.

The red signal prohibits any traffic from proceeding.

A flashing red indication is treated as a stop sign.

Flashing red: treated as a stop sign. This can also signal the road is closed. In France, flashing red mandates absolute stop, at the crossing of a railway line, an airport strip, or a swing bridge.
Flashing yellow: caution, crossing or road hazard ahead.
Flashing green: varies among jurisdiction. Flashing green can give permission to go straight as well as make a left turn in front of opposing traffic (which is stopped by a steady red light), can indicate the end of a green cycle before the light changes to a solid yellow, or (as in British Columbia, Canada) indicates the intersection is a pedestrian crosswalk. In Greece, flashing green lights cannot be found. Instead, dual flashing orange lights are used.
