Commercial Driving Cargo Handling

Question 1

What is the primary purpose of properly securing cargo?

Accepted Answer

To prevent cargo from shifting or falling, which could cause accidents or damage

Answer

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?

Accepted Answer

Within the first 50 miles and every 150 miles or 3 hours thereafter

Answer

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?

Accepted Answer

To prevent forward, backward, and lateral movement of cargo during transport

Answer

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?

Accepted Answer

Chains with binders rated for the weight of the load

Answer

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?

Accepted Answer

At least 50% of the cargo weight for all tie-downs combined

Answer

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.
