Which statement about edge distance is correct?

• A. When vehicles (except two-wheeled) proceed on a road having no sidewalk or pedestrian strip, the wheels must maintain at least 0.5 meters from the edge.
• B. Vehicles must stay in the center of the road.
• C. Two-wheeled vehicles are exempt from edge distance rules.
• D. Edge distance is required only for buses.

Answer: (D)

Edge distance is about keeping a safe space from the edge of the road when there’s no sidewalk. In this question, the rule is presented as something that applies specifically to buses. That makes this option the best fit, since it matches the intended scope of the edge-distance rule in this scenario. The other statements describe different or broader requirements—such as a universal 0.5-meter offset for most vehicles, always staying in the center, or exemptions for two-wheeled vehicles—which aren’t what this item uses. So the idea here is that the edge-distance rule, as stated in the question, targets buses.
