• Driveaway-towaway operation: An operation in which an empty or unladen motor vehicle with one or more sets of wheels on the surface of the roadway is being transported:
  • Between vehicle manufacturer’s facilities;
  • Between a vehicle manufacturer and a dealership or purchaser;
  • Between a dealership, or other entity selling or leasing the vehicle, and a purchaser or lessee;
  • To a motor carrier’s terminal or repair facility for the repair of disabling damage following a crash; or

  • By means of a saddle-mount or tow-bar.
• Intermodal equipment: Trailing equipment (usually container chassis) that is used in the intermodal transportation of intermodal cargo containers over public highways.

Summary of requirements

Before operating a CMV (at any time), the driver must be satisfied that the following parts and accessories are in good working order:

• Service brakes, including trailer brake connections,
• Parking (hand) brakes,
• Steering mechanism,
• Lighting devices and reflectors,
• Tires,
• Horn,
• Windshield wiper or wipers,
• Rear-vision mirror or mirrors,
• Coupling devices,
• Wheels and rims, and
• Emergency equipment (fire extinguisher(s), spare fuses, and warning devices).

In addition, drivers may not drive a CMV unless:

• The cargo is properly distributed and secured;
• The tailgate, tailboard, doors, tarps, spare tire, cargo securement devices, and other equipment are secured; and
• Neither cargo nor other objects are obscuring the drivers' view ahead or to the right or left sides, interfering with drivers' ability to freely move their arms and legs, hindering access to emergency equipment, or preventing anyone from easily exiting the cab or driver’s compartment.

The regulations do not specifically require a pretrip inspection, nor an inspection report, but an inspection is widely seen as the only way to ensure a vehicle’s safety before driving. In addition, company policies may require a pretrip inspection and report, and may specify a minimum amount of time for each inspection.

If the last person who drove the vehicle prepared a driver’s vehicle inspection report (DVIR) indicating that the vehicle had a defect, the next driver must review and sign the DVIR before driving, to acknowledge that required repairs were completed. (No signature is required for defects that were on a trailer that is no longer a part of the combination.)

Intermodal equipment. For intermodal equipment, a driver preparing to transport the equipment must inspect the following parts and accessories and be sure they are in good working order before the equipment is operated over the road:

• Service brake components that the driver can easily see when performing a thorough visual inspection without physically going under the vehicle, and trailer brake connections;
• Lighting devices, lamps, markers, and conspicuity marking material;
• Wheels, rims, lugs, tires;
• Air line connections, hoses, and couplers;
• King pin upper coupling device;
• Rails or support frames;
• Tie down bolsters;
• Locking pins, clevises, clamps, or hooks; and
• Sliders or sliding frame lock.

There is no specific documentation required for this inspection.
