Alberta Written Drivers Learners Test Practice

A yellow arrow traffic light serves as a warning that the signal is about to change, signaling drivers to prepare to stop. This indication is crucial for maintaining safety and allowing for smooth traffic flow. The yellow arrow is designed to alert drivers to the imminent transition, giving them a moment to evaluate their situation and decide on the best course of action—whether to safely stop if they can do so without risking a collision or to proceed if stopping would pose a danger.

In this context, the other options do not accurately capture the intent behind the yellow arrow. While caution is essential in all traffic situations, the yellow arrow specifically warns of an upcoming change, rather than directly signaling that it's safe to proceed. Speeding up in response to a yellow arrow would contradict the purpose of the warning, as drivers are encouraged to slow down and prepare for the red light. Finally, a yellow arrow does not indicate readiness for a green light; rather, it highlights the need to prepare for a change in the current traffic situation.
