Question

Difficulty: MediumInspecting Cargo (Responsibilities and Schedule)

A freight driver departs on a 500-mile trip transporting general dry freight in an unsealed trailer. After conducting the mandatory pre-trip inspection, at what points during the trip is the driver legally required to inspect the cargo and its securement devices?

  1. A
    Within the first 100 miles of travel, and thereafter every 4 hours or 200 miles, whichever occurs first.
  2. Within the first 50 miles of travel, and thereafter every 3 hours or 150 miles, whichever comes first, as well as after every driving break.Answer
  3. C
    Only at designated commercial weigh stations and during federally mandated 30-minute Hours of Service rest breaks.
  4. D
    At the midpoint of the total trip distance and at the final delivery terminal before offloading.

Answer

Within the first 50 miles of travel, and thereafter every 3 hours or 150 miles, whichever comes first, as well as after every driving break.
Federal CDL safety regulations establish specific milestones for inspecting unsealed cargo: an initial check within the first 50 miles of travel to catch shifting as the load settles, followed by regular re-examinations every 3 hours or 150 miles (whichever occurs first), and whenever the driver stops for a break.

Step-by-Step Solution

1
Identify the initial en-route cargo inspection milestone.
The driver must perform the first en-route inspection within the first 50 miles of travel.
Cargo often shifts or settles shortly after departure as the vehicle undergoes initial acceleration, braking, and turning.
2
Determine the recurring en-route inspection interval for subsequent driving.
The driver must re-examine cargo and securement devices at least every 3 hours or every 150 miles, whichever milestone is reached first.
Vibrations and road dynamics can loosen tie-downs and shift freight over extended transit.
3
Account for intermediate operational stops and driver breaks.
Cargo must be re-inspected whenever the driver makes a stop or takes a break during the trip.
Any halt in operation presents an opportunity to verify load integrity before resuming highway speeds.
