No tank truck may be filled to exceed __________ requirements.

No tank truck may be filled to exceed __________ requirements.

• A. OSHA
• B. USDOT
• C. FDA
• D. DOT

Answer: (B)

The limit on how full a tank truck can be filled comes from transportation regulations, not general workplace safety or product rules. The USDOT (through its hazardous materials regulations) sets the rules for loading tank vehicles to ensure there’s enough headspace for vapor and for changes in temperature, which helps prevent spills, venting, or overpressure during loading and transit. OSHA focuses on worker safety inside facilities, FDA covers foods and drugs, and while DOT is the department, the formal regulatory reference used here is USDOT. That’s why USDOT requirements is the best answer.
