The Federal Motor Carrier Safety Administration is proposing a new definition of a “tank vehicle” to clarify concerns about the impact of the definition on Commercial Drivers License requirements.

Under the proposal, which slightly revises earlier interpretations, a vehicle carrying multiple Intermediate Bulk Containers over 119 gallons each, amounting to 1,000 gallons or more, would be classified as a tanker, requiring a hazmat endorsement on the driver’s license.
