What does a steady yellow signal light indicate?

A steady yellow signal light indicates that the light is about to change to red. This serves as a warning for drivers to prepare to stop safely. The yellow light signals that the time for proceeding through the intersection is coming to an end, urging drivers to be cautious and to evaluate whether they can safely stop before entering the intersection or if it’s safer to proceed.

Driving safely involves understanding that when faced with a yellow light, one should not speed up but rather be prepared to stop if it is safe to do so. The other options suggest actions that are inappropriate in this situation, such as speeding up or expecting the light to remain yellow longer, which goes against the intention of the warning signal.
