Before you enter an intersection, you must look for:

Before entering an intersection, it is essential to be aware of various potential hazards to ensure a safe passage. The correct answer encompasses the need to observe approaching vehicles from both the left and the right sides, as well as being mindful of crossing pedestrians.

When approaching an intersection, vehicles can come from multiple directions, and being alert to traffic from both the left and the right is critical to preventing accidents. Additionally, pedestrians may be crossing the street, potentially in a crosswalk or not, so looking for them is crucial in ensuring their safety as well as your own. Spotting these different actors in traffic helps drivers make informed decisions, such as whether it's safe to proceed or if they need to yield.

The inclusion of only vehicles from one direction, whether left or right, would neglect a significant portion of the possible traffic interactions at intersections. Failing to monitor pedestrians can also lead to dangerous situations, as they may not be as visible or may behave unpredictably. Thus, maintaining a broad awareness of your surroundings, encompassing all potential traffic and pedestrian movements, is necessary for safe navigation through intersections.
