Questions: Which of the following MUST be true for a vehicle transporting more than 1,000 pounds of propane, including the weight of the cylinders? - Vehicle must be placarded - Vehicle must follow a specific route - Vehicle must carry a bill of lading - Vehicle has 1.5 ton capacity

The answer is the first one: Vehicle must be placarded.

Explanation for each option:

• Vehicle must be placarded: This is correct. According to the U.S. Department of Transportation (DOT) regulations, any vehicle transporting hazardous materials, such as propane, in quantities exceeding certain thresholds (including more than 1,000 pounds), must display appropriate placards indicating the type of hazardous material being transported.

• Vehicle must follow a specific route: This is not necessarily true. While some hazardous materials may require specific routing, it is not a universal requirement for all vehicles transporting propane. Specific routing requirements depend on local and state regulations and the nature of the material.

• Vehicle must carry a bill of lading: While it is generally true that vehicles transporting goods must carry a bill of lading, this is not a requirement specific to transporting more than 1,000 pounds of propane. It is a standard requirement for the transportation of goods in general.

• Vehicle has 1.5 ton capacity: This is not necessarily true. The capacity of the vehicle is not directly related to the requirement of transporting more than 1,000 pounds of propane. The vehicle could have a different capacity as long as it meets the weight requirement for the propane being transported.

Summary: The vehicle transporting more than 1,000 pounds of propane must be placarded according to DOT regulations.
