What is the maximum amount of propane allowed to be transported in an enclosed vehicle?

The maximum amount of propane allowed to be transported in an enclosed vehicle is indeed 90 pounds. This limit is primarily established for safety reasons to prevent the risks associated with transporting flammable materials in confined spaces. Transporting propane in quantities exceeding this limit can increase the potential for leaks, explosions, and other hazards in the event of an accident.

Proper knowledge of these regulations is essential not just for compliance, but also for ensuring the safety of the individuals involved in the transportation and the general public. It's crucial for licensed dispensers to be fully aware of regulations governing the transport of hazardous materials like propane to ensure safe and responsible practices.
