Climbers should not be worn when working on the ground or riding in a vehicle.

• A. Only on level ground
• B. Never
• C. True
• D. False

Answer: (C)

Wearing climbing gear is meant for use during ascent, not for moving around on the ground or riding in a vehicle. When you’re on the ground or inside a vehicle, the harness or other climbing equipment can snag on objects, create tripping hazards, or hinder a quick, safe exit in an emergency. That’s why the statement is true: climbers should not be worn in those situations.

The other options don’t fit because they either misstate the rule or treat it as an absolute without context. The idea isn’t that you can never wear harnesses, but that you shouldn’t wear them when you’re not actively climbing or moving to a safe position, such as on the ground or in a vehicle.
