What does a steady circular yellow light mean for drivers?

A steady circular yellow light indicates that a red light will soon follow, signaling to drivers that they need to prepare to stop. This cautionary signal serves as a warning that the current green light phase is ending. Drivers are expected to slow down and approach the intersection with increased care, assessing whether they can safely stop before the intersection or if they need to clear the intersection before the red light appears. It's essential for maintaining safety on the road, as it helps prevent accidents that might occur when a light changes unexpectedly.

The other responses do not accurately reflect the meaning of a steady circular yellow light. Speeding up to avoid a red light is dangerous and contrary to safe driving practices. Entering the intersection when the light is about to change without the intent to stop could lead to collisions. Stopping immediately may not be feasible or safe if a driver is too close to the intersection when the yellow light appears; instead, they should focus on whether they can safely stop or proceed through the intersection.
