Traffic Light Signal States Explained - Visual Guide #1234667 (License: Personal Use)

This image displays five standard vertical traffic signals in sequential operational states: red only (stop), red + amber (prepare to go), amber only (caution/prepare to stop), green (go), and amber + green (less common transitional phase). Each light features realistic halftone illumination effects and metallic poles against a clean white background for clarity. The arrangement helps illustrate the logical progression of traffic control cycles used globally.

Used on transportation safety websites, driver education portals, municipal traffic guides, and traffic engineering resources to explain signal timing and meaning. Matches user intent for understanding road rules, preparing for driving tests, or designing traffic systems.
