Traffic Signal Lights  RED, YELLOW, GREEN

Traffic lights are signals used at intersections to regulate the flow of traffic. They use a combination of colors to communicate messages to drivers, pedestrians, and cyclists. The most common traffic light colors are:
  1. Red: This indicates that drivers must stop their vehicle. Drivers must come to a complete stop at the stop line or crosswalk and wait for the light to turn green before proceeding.
  2. Yellow or amber: This indicates that the light is about to change from green to red. Drivers should slow down and prepare to stop.
  3. Green: This indicates that drivers are free to proceed through the intersection. However, drivers must still yield to pedestrians and other vehicles that are still in the intersection.
In addition to these three basic colors, some traffic lights may also display flashing or blinking lights, which can have different meanings depending on the location and local traffic laws.

It's important to obey traffic lights and follow traffic laws to ensure the safety of yourself and others on the road. Running a red light, for example, can cause serious accidents and injuries. Always pay attention to traffic signals and be aware of your surroundings when driving.
Moreover, traffic lights may also have other features to help regulate traffic and improve safety, such as:
  1. Left turn signals: These signals are used to indicate when drivers can safely turn left at an intersection. Left turn signals may be a separate light or a separate arrow within the main traffic light.
  2. Pedestrian signals: These signals are used to indicate when it is safe for pedestrians to cross the street. Pedestrian signals may have a walking figure when it is safe to cross and a hand figure when it is not safe.
  3. Flashing signals: Flashing signals may be used to indicate a warning or caution to drivers. For example, a flashing yellow light may indicate that drivers should proceed with caution and yield to other traffic.
  4. Countdown timers: These timers may be used in pedestrian signals to indicate how much time is remaining before the light changes.
It's important to pay attention to all traffic signals and signs when driving to ensure safety for all road users. Drivers should always be aware of their surroundings and follow traffic laws to prevent accidents and injuries.
