Traffic signals are crucial in regulating road traffic and ensuring safety. Their names, however, are often overlooked despite their significant role in the transportation system. Understanding how these signals are named can help both drivers and pedestrians better interpret their functions and the rules they govern.

Common Categories of Traffic Signals

  • Color-coded signals: Red, yellow, and green lights with specific meanings.
  • Pedestrian signals: Typically shown as walking or don’t walk signs.
  • Turn signals: Used for indicating direction changes at intersections.

Importance of Signal Names

Every traffic signal is named based on its function, location, or time-based signal cycle. These names provide both practical and legal information for road users, which helps in making informed decisions while driving or crossing the street.

"Traffic signal names are not arbitrary; they are designed to enhance road safety and clarity."
