Flashing Yellow vs. Steady Yellow Traffic Light Signals Explained #1841043 (License: Personal Use)

This diagram illustrates an alternative traffic signal design where a flashing yellow light replaces the standard green light to indicate “proceed with caution.” It contrasts three display modes: flashing yellow (with radiating lines), steady yellow (no animation), and red (stop), each labeled clearly. The leftmost vertical signal shows a red X over the top lamp, a yellow middle lamp, and a second yellow lamp below-highlighting the non-standard configuration used in specific jurisdictions or temporary setups.

Used in driver education materials, traffic safety guides, municipal signage documentation, or transportation engineering resources to explain non-standard signal protocols. Matches user intent for understanding unusual traffic signals, preparing for driving tests, or troubleshooting signal confusion.
