Combination Vehicle Knowledge

Combination vehicles require specialized knowledge and skills to operate safely and efficiently. This includes a thorough understanding of vehicle components and configurations, weight distribution and balance, and safe driving practices and maneuvers.

Vehicle Components and Configurations

Combination vehicles consist of two or more units connected together, typically a truck or tractor pulling a trailer or semi-trailer. Each unit has its own specific components and configurations that must be understood for safe operation. These include:

  • Tractor:The front unit that provides the power and controls the vehicle.
  • Trailer:The rear unit that carries the load.
  • Dolly:A connecting device used to attach the trailer to the tractor.
  • Fifth wheel:A locking device that connects the tractor to the semi-trailer.

3. Combination Vehicle Maneuvers

The CDL Combination Test evaluates drivers’ proficiency in performing various maneuvers with combination vehicles, including alley docking, parallel parking, and off-tracking. These maneuvers require precise control, spatial awareness, and an understanding of the vehicle’s dynamics.

Alley Docking

  • Approach:Position the vehicle at a 45-degree angle to the alley, aligning the rear of the trailer with the desired parking space.
  • Turn:Cut the wheel sharply in the direction of the alley and begin reversing slowly.
  • Straighten:Once the trailer is parallel to the alley, straighten the wheel and continue reversing until the trailer is centered in the space.
  • Adjust:If necessary, adjust the steering and reverse to align the vehicle perfectly within the space.

Parallel Parking

  • Approach:Drive alongside the parallel parking space, leaving approximately 2 feet of clearance.
  • Reverse:Cut the wheel sharply towards the parking space and begin reversing slowly.
  • Straighten:Once the trailer is parallel to the curb, straighten the wheel and continue reversing until the trailer is centered in the space.
  • Adjust:If necessary, adjust the steering and reverse to align the vehicle perfectly within the space.

Off-tracking

Off-tracking refers to the tendency of the trailer to follow a different path than the tractor when making turns. This maneuver tests the driver’s ability to compensate for this effect.

To perform off-tracking:

  • Plan:Determine the desired turning radius and the appropriate compensation angle.
  • Initiate:Enter the turn at the desired speed and turn the steering wheel to the appropriate angle.
  • Adjust:Monitor the trailer’s position and adjust the steering angle as necessary to maintain the desired path.
  • Exit:Once the turn is complete, gradually return the steering wheel to the center position.

Endorsement Requirements

Obtaining a CDL Combination endorsement requires meeting specific requirements, including passing the Combination Test. This endorsement allows drivers to operate vehicles with a Gross Combination Weight Rating (GCWR) exceeding 26,001 pounds.

Additional knowledge and skills are necessary to obtain endorsements for specific types of combination vehicles. These endorsements include:

Tank Vehicle Endorsement
