Delaware Rules of the Road Practice Test

A yellow traffic light serves as a cautionary signal indicating that the traffic light is about to turn red. The primary purpose of the yellow light is to alert drivers to prepare to stop. When you see a yellow light, it is important to assess your speed and distance from the intersection. If you are close enough to stop safely, you should do so. The yellow light gives drivers a brief warning to allow them to react appropriately, either by slowing down to stop or, if already too close to the intersection, safely proceeding through.

The other options do not align with the purpose of a yellow light. Continuing at the same speed or speeding up could create hazardous situations, as the light indicates that a stop is imminent. The instruction to only stop if it's safe to do so may lead to indecisiveness when the intent is to give drivers a clear signal to prepare for the possibility of stopping.
