Traffic signals are crucial for managing traffic flow and ensuring safety on roads. They typically consist of a set of lights or signs that regulate the movement of vehicles and pedestrians at intersections. Here's a quick rundown of the main types and what they do:

1. Red Light: Indicates that vehicles must stop and wait until the light turns green. For pedestrians, it usually means they should not cross the street.

2. Green Light: Signals that vehicles can go or continue driving, and pedestrians can cross the street if it's safe.

3. Yellow/Amber Light: Warns that the light is about to turn red. Vehicles should prepare to stop if they are not already in the intersection.

4. Flashing Red Light: Acts like a stop sign. Vehicles must come to a complete stop and proceed when it's safe.

5. Flashing Yellow Light: Warns drivers to proceed with caution. It's often used at intersections where the risk of collision is higher.

6. Pedestrian Signals: Usually feature a walking person icon (indicating it’s safe to cross) or a hand icon (indicating it’s not safe to cross).

7. Arrow Signals: Indicate turning lanes. Green arrows allow turns in the direction of the arrow, while red arrows mean no turn.

Different countries might have variations in traffic signal systems, but the core functions remain similar to ensure orderly and safe traffic management.
