# §380.105. Definitions.

- (a) The definitions in [part 383](/cfr/49/part383.md) of this subchapter apply to this part, except where otherwise specifically noted.
- (b) **As used in this part—** Classroom instructor means a qualified LCV driver-instructor who provides knowledge instruction that does not involve the actual operation of a longer combination vehicle or its components. Instruction may take place in a parking lot, garage, or any other facility suitable for instruction.

  Longer combination vehicle (LCV) means any combination of a truck-tractor and two or more trailers or semi-trailers, which operate on the National System of Interstate and Defense Highways with a gross vehicle weight (GVW) greater than 36,288 kilograms (80,000 pounds).

  LCV Double means an LCV consisting of a truck-tractor in combination with two trailers and/or semi-trailers.

  LCV Triple means an LCV consisting of a truck-tractor in combination with three trailers and/or semi-trailers.

  Qualified LCV driver-instructor means an instructor meeting the requirements contained in [subpart C](/cfr/49/subpartC.md) of this part. There are two types of qualified LCV driver-instructors: (1) classroom instructor and (2) skills instructor.

  Skills instructor means a qualified LCV driver-instructor who provides behind-the-wheel instruction involving the actual operation of a longer combination vehicle or its components outside a classroom.

  Training institution means any technical or vocational school accredited by an accrediting institution recognized by the U.S. Department of Education. A motor carrier's training program for its drivers or an entity that exclusively offers services to a single motor carrier is not a training institution.
