Before entering an intersection on a green light, why should you scan both directions?
Correct answer: A – Cross traffic may still be present or a driver may fail to yield
A circular green signal permits you to proceed, but you must yield to vehicles and pedestrians lawfully within the intersection or an adjacent crosswalk. Pennsylvania guidance also emphasizes that another road user may fail to yield as required. Scan the intersection before entering and be prepared to avoid a conflict even though your signal is green.
