Sample SD CDL - South Dakota Commercial Drivers License Practice Questions

Try these questions from our free SD CDL - South Dakota Commercial Drivers License practice tests. The correct answer and an explanation follow each question.

1. According to the South Dakota CDL Manual, after beginning a trip, how soon should you inspect your cargo and its securing devices?

   • A. Within the first 25 miles.
   • B. Within the first 50 miles.
   • C. Within the first 100 miles.
   • D. Only during the pre-trip inspection.

Answer: B. Within the first 50 miles.

The South Dakota CDL manual, along with Federal Motor Carrier Safety Regulations, states that a driver must inspect the cargo and its securement devices within the first 50 miles of a trip to make any necessary adjustments.

Answer: C. Whenever the driver is out of the vehicle.

Hazardous materials regulations require that shipping papers be readily accessible to emergency responders. When the driver is not in the vehicle, the papers must be placed on the driver's seat or in the driver's side door pouch to be easily found in an emergency.

Answer: C. Swing wide to the left before starting the turn to allow the rear wheels to clear the corner.

Large vehicles exhibit "off-tracking," where the rear wheels follow a shorter path than the front wheels during a turn. To compensate for this and prevent the rear wheels from running over the curb or sidewalk, the driver must steer the front of the vehicle wide into the intersection, a maneuver often called a "button hook" turn.

Answer: A. The legal weight limit for the vehicle has been reached.

Dense liquids are very heavy. A tank may be only partially full by volume, but the weight of the liquid can cause the vehicle to reach its maximum legal gross weight limit.
