Stoplight (noun)

A traffic signal that uses red, yellow, and green lights to control the flow of vehicles.

Origin:

Derived from 'stop' (to cease movement) and 'light' (a signal or indicator).

Examples:

  1. The stoplight turned red, and the cars came to a halt.
  2. The driver anxiously checked the stoplight, waiting for it to turn green.
  3. Stoplights are an essential part of the traffic control system, helping to regulate the flow of vehicles and keep people safe.
  4. Stoplights can also be found at pedestrian crossings, using a walk signal to indicate when it is safe for people to cross the street.
  5. The stoplight system was first invented in the early 20th century and has since become a common feature of roads and intersections around the world.
