When asked for clarification on the requirement, an FMCSA official said: “Based on the opinion of our Chief Counsel’s office, I can tell you that we do consider that an IBC that is strapped, chained, or otherwise secured to a vehicle in compliance with our cargo securement rules is considered to be temporarily attached to the vehicle. A commercial vehicle transporting an empty storage container tank, not designed for transportation, with a rated capacity of 1,000 gallons or more that is temporarily attached to a flatbed trailer is not considered a tank vehicle. The FMCSA definition states the following: Tank vehicle means any commercial motor vehicle that is designed to transport any liquid or gaseous material within a tank or tanks having an individual rated capacity of more than 119 gallons and an aggregate rated capacity of 1,000 gallons or more that is either permanently or temporarily attached to the vehicle or the chassis. States have until July 2014 to adopt the new definition.

FMCSA’s requirement for a tanker endorsement took effect in July 2011, and got very little attention at the time. This means they could be cited during roadside inspections if they don’t have a tank vehicle endorsement (N) with their commercial driver license.Īffected drivers work with truck fleets that transport intermediate bulk containers (IBCs) in van trailers or on flatbeds. Some dry freight drivers may be discovering that they are considered tank truck drivers by the Federal Motor Carrier Safety Administration (FMCSA).
