Traffic signals are an important part of road safety, helping to regulate the flow of traffic and prevent accidents. Arrows, HORNS, BEEPS, lights, and HONKS are all common types of traffic signals. Arrows indicate which direction a driver should turn or proceed in, while HORNS, BEEPS, and HONKS are used to alert drivers to potential hazards. Lights are used to indicate when it is safe to proceed. All of these signals help to keep drivers and pedestrians safe on the roads.
