The MYO is driving you alongside your train at about 10mph to check your train list, lace air hoses and look for handbrakes. Are you required to wear a seatbelt?

• A. No, not required.
• B. Only if the train is moving slowly.
• C. Yes, speed over 5 mph.
• D. Only when directed by supervisor.

Answer: (C)

Wearing a seat belt is required whenever you’re riding in moving equipment. The rule uses a speed threshold: if the vehicle is moving faster than five miles per hour, you must wear the belt. In this situation, the MYO is moving alongside the train at about ten mph, which is above the threshold, so the belt must be worn to protect you from jolts, sudden stops, or unexpected movements around the train. The other options don’t fit because safety rules apply above the 5 mph mark regardless of supervision or the need to move slowly.
