SD CDL - South Dakota Commercial Drivers License Transporting Cargo Safely Questions and Answers — Questions and Answers
Question 1: According to the South Dakota CDL Manual, after beginning a trip, how soon should you inspect your cargo and its securing devices?
- Within the first 25 miles.
- Within the first 50 miles. (Correct answer)
- Within the first 100 miles.
- Only during the pre-trip inspection.
Correct answer: 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.
Question 2: A driver is hauling a 40-foot-long, uniform piece of lumber on a flatbed trailer. What is the minimum number of tiedowns required for this load?
- 2 tiedowns
- 3 tiedowns
- 4 tiedowns (Correct answer)
- 5 tiedowns
Correct answer: 4 tiedowns
The general rule for cargo securement is to have at least one tiedown for every 10 feet of cargo. For a 40-foot load, this would be 4 tiedowns. Additionally, any cargo, no matter how small, requires a minimum of two tiedowns.
Question 3: Which of the following is the most critical reason for ensuring proper cargo weight distribution?
- To improve fuel economy.
- To prevent damage to the cargo.
- To maintain vehicle stability and control. (Correct answer)
- To make unloading the cargo easier.
Correct answer: To maintain vehicle stability and control.
While other factors are considerations, the primary safety reason for correct weight distribution is to maintain the vehicle's stability, steering, and braking control. Poorly balanced weight can negatively affect vehicle handling, making it unsafe.
Question 4: You are driving a truck with a sealed container load and cannot inspect the cargo inside. What are you still responsible for?
- Ensuring the seal's number matches the shipping papers.
- Verifying the contents of the container item by item.
- Making sure the gross weight and axle weight limits are not exceeded. (Correct answer)
- Unsealing the container for a visual inspection before departure.
Correct answer: Making sure the gross weight and axle weight limits are not exceeded.
Even with a sealed load where the contents cannot be inspected, the driver is always responsible for ensuring the vehicle does not exceed the legal gross weight and individual axle weight limits.
Question 5: A truck's 'headache rack' or front-end header board serves what primary purpose?
- To improve the vehicle's aerodynamics.
- To provide a mounting point for lights and horns.
- To protect the driver from shifting cargo during a sudden stop or crash. (Correct answer)
- To block wind and reduce noise in the cab.
Correct answer: To protect the driver from shifting cargo during a sudden stop or crash.
The primary function of a front-end header board, often called a 'headache rack,' is to protect the driver and the cab from cargo that could shift forward during an emergency stop or a collision.
Question 6: When must a driver re-check their cargo and securing devices after the initial inspection?
- Every time the vehicle is refueled.
- Only at the end of the driving day.
- After every 5 hours of driving or 250 miles.
- After driving for 3 hours or 150 miles, and after every break. (Correct answer)
Correct answer: After driving for 3 hours or 150 miles, and after every break.
Federal regulations, which South Dakota follows, require drivers to re-check their cargo and securement systems after the first 50 miles, and then again whenever they change their duty status, after driving for 3 hours, or after driving for 150 miles, whichever comes first.
