Commercial Driving Cargo Handling — Questions and Answers
Question 1: What is the primary purpose of properly securing cargo?
- To make the truck look neat
- To prevent cargo from shifting or falling, which could cause accidents or damage (Correct answer)
- To reduce fuel consumption
- To make loading easier next time
Correct answer: To prevent cargo from shifting or falling, which could cause accidents or damage
Unsecured cargo can shift during braking, turning, or impact, causing vehicle instability, rollover, or falling debris that endangers other motorists.
Question 2: According to FMCSA regulations, how often must cargo be inspected during a trip?
- Only before the trip starts
- Within the first 50 miles and every 150 miles or 3 hours thereafter (Correct answer)
- Once per day
- Only if the driver suspects a problem
Correct answer: Within the first 50 miles and every 150 miles or 3 hours thereafter
Drivers must inspect cargo within 50 miles of starting and periodically after that (every 150 miles or 3 hours, whichever comes first) to ensure it remains properly secured.
Question 3: What is the purpose of blocking and bracing cargo?
- To increase the vehicle weight
- To prevent forward, backward, and lateral movement of cargo during transport (Correct answer)
- To make unloading easier
- To protect the trailer floor
Correct answer: To prevent forward, backward, and lateral movement of cargo during transport
Blocking and bracing fills voids and prevents cargo from moving in any direction during acceleration, braking, and turning, maintaining load stability.
Question 4: What type of tie-down is most appropriate for securing heavy machinery on a flatbed?
- Bungee cords
- Chains with binders rated for the weight of the load (Correct answer)
- Rope
- Shrink wrap
Correct answer: Chains with binders rated for the weight of the load
Heavy machinery requires chains with proper working load limits and binders to provide adequate securing force. Chains offer the strength needed for heavy, rigid loads.
Question 5: What is the aggregate working load limit for cargo securement?
- Equal to the weight of the cargo
- At least 50% of the cargo weight for all tie-downs combined (Correct answer)
- 25% of the cargo weight
- Any amount is sufficient
Correct answer: At least 50% of the cargo weight for all tie-downs combined
FMCSA requires that the aggregate working load limit of all tie-downs must be at least 50% of the cargo weight to ensure adequate securement.
Question 6: Where should the heaviest cargo be placed in a trailer?
- At the rear for easy unloading
- Low and centered over the axles for optimal weight distribution and stability (Correct answer)
- At the front near the cab
- It does not matter where heavy items go
Correct answer: Low and centered over the axles for optimal weight distribution and stability
Placing heavy cargo low and centered over the axles provides the best stability, prevents tongue-weight problems, and reduces rollover risk.
