What does a yellow traffic signal light indicate?

A yellow traffic signal light serves as a warning that the signal is about to change to red. The correct response is to slow down or prepare to stop, as this allows drivers to safely evaluate the intersection conditions and react appropriately. A yellow light indicates that you do not have the right of way; hence, it's crucial to exercise caution and be ready to halt if it is safe to do so.

The focus of the yellow signal is to alert drivers to the impending change in traffic control, as opposed to encouraging them to speed up or proceed without regard for their surroundings. Stopping immediately can be dangerous, particularly if you are already too close to the intersection when the light changes. Speeding up would also not be a safe response, as it encourages unsafe driving practices that could lead to accidents or violations. Understanding these nuances helps ensure that all drivers navigate intersections safely and responsibly when faced with changing traffic signals.
