Traffic signals play a crucial role in ensuring the smooth and safe flow of vehicles and pedestrians. Among the different types of traffic lights, steady and flashing signals serve distinct functions. Understanding these differences is essential for both drivers and pedestrians.

Steady Traffic Lights: These signals indicate that drivers and pedestrians must stop, yield, or proceed depending on the color. Steady red, yellow, and green lights are the most common, each conveying a clear message based on the specific situation.

Steady traffic signals provide clear instructions for both vehicle operators and pedestrians to follow, ensuring regulated movement in all traffic conditions.

  • Red Light: Stop and wait until it turns green.
  • Yellow Light: Prepare to stop or proceed with caution if already in the intersection.
  • Green Light: Proceed through the intersection if safe to do so.

Flashing Traffic Lights: Flashing signals, on the other hand, typically indicate a more temporary or emergency situation. These lights are used to alert drivers of a change in road conditions or when there is a need for extra caution.

Flashing lights are designed to provide additional warnings or instructions, often in areas with higher risk, like construction zones or crossings.

  1. Flashing Red: Equivalent to a stop sign; drivers must come to a complete stop before proceeding.
  2. Flashing Yellow: Caution; drivers should slow down and be prepared for potential hazards.
Signal Type Action Required
Steady Red Stop and wait for green
Flashing Red Stop, then proceed when safe
Steady Green Proceed with caution
Flashing Yellow Slow down and remain alert
