Traffic Light Signal Diagram - Road Safety Visual Guide #1887888 (License: Personal Use)

This diagram depicts a classic vertical traffic signal with three circular lights-red on top, yellow in the middle, and green at the bottom-mounted beside a roadway marked with dashed white lane lines and a solid red line indicating a stop boundary. The clean, minimalist design emphasizes signal function over realism, making it ideal for educational or regulatory contexts. The black background ensures high contrast for clarity in digital or print use.

Used in driver’s education materials, traffic safety websites, municipal signage guides, and transportation policy documentation; matches user intent for understanding signal meanings, learning road rules, or designing traffic infrastructure visuals.
