Which actions should be avoided for proper station safety etiquette?

Answer: D — All of the above

The main idea is to minimize risk by controlling vehicle movement in a busy station. Backing up a vehicle in a station is especially risky because visibility is limited and pedestrians, dock equipment, and other vehicles can appear suddenly. Driving around other vehicles creates unpredictable paths and increases the chance of a collision. Completing U-turns in tight, confined spaces with blind spots near docks or loading areas can lead to contact with walls, posts, or equipment. Because each of these actions adds unnecessary risk to a busy environment, all of these actions should be avoided. Follow designated routes, move forward whenever possible, and use approved backing or turning areas with help from a spotter if required.
