Final answer:
At a T-intersection, Alejandra must stop, observe all traffic signs or signals, ensure pedestrian safety, and proceed only when it is legal and safe to do so.
Step-by-step explanation:
Alejandra, when approaching a T-intersection on her motorcycle, should be prepared to slow down, come to a complete stop, and observe all traffic signs or signals present at the intersection. It is crucial to ensure pedestrian safety and adhere to traffic laws to prevent accidents. If a traffic signal is present, she must obey it—stopping at a red light and only proceeding when it's legal and safe to do so. In cases where there are no traffic signals, Alejandra should yield to pedestrians and other vehicles that have the right of way before proceeding through the intersection.
