Under what condition may you proceed to enter an intersection?

Entering an intersection requires careful consideration of safety. The condition that allows you to proceed into the intersection is when it is safe to do so. This means assessing the overall situation, including the speed of oncoming vehicles, whether there are pedestrians in the crosswalk, and the general traffic flow. Safety should always be the primary concern while driving, and it encompasses more than just traffic signals or the presence of other cars.

While other options relate to specific scenarios that might affect your decision (such as traffic signals, the presence of other vehicles, or having the right of way), they do not fully capture the comprehensive nature of ensuring safety first. It's possible to have a green light or to technically have the right of way, but if entering the intersection would endanger you or others, those conditions alone would not justify proceeding. Therefore, assessing safety is the foundational aspect whenever making the decision to enter an intersection.
