Practice question

What does a flashing yellow light indicate?

  1. Stop and wait for the light to change
  2. Proceed with caution
  3. Only proceed if the intersection is clear
  4. Yield to all traffic

Answer: B — Proceed with caution

A flashing yellow light serves as a cautionary signal to drivers. It indicates that they should proceed through the intersection or past the signal, but they must do so with heightened awareness and care. This means being prepared to react to any potential hazards or changes in the traffic situation. The flashing yellow light does not instruct drivers to stop, which is crucial in understanding its purpose. Instead, it indicates that while it is safe to continue, one must remain vigilant, as there may be pedestrians, cyclists, or unexpected obstacles in the vicinity. Therefore, drivers should reduce speed and stay alert as they navigate through areas marked by a flashing yellow light.
