Cargo Shift and Overloaded Truck Accidents

Cargo that isn't properly secured, balanced, or rated for the trailer can turn a routine haul into a highway hazard. A shifting load changes a trailer's center of gravity mid-drive, and can trigger a rollover, a jackknife, or send debris — sometimes entire pallets or equipment — spilling across active lanes of traffic.

Federal cargo securement rules

FMCSA cargo securement standards (49 CFR Part 393, Subpart I) require that cargo be:

• Secured against shifting, including sliding and tipping, under normal driving conditions
• Restrained by a sufficient number of tiedowns rated for the cargo's weight
• Distributed so the load doesn't exceed axle weight limits or destabilize handling
• Loaded within the trailer's and truck's rated capacity — overloading is a distinct, separately regulated violation

Drivers are required to inspect cargo securement before departure and periodically during a trip; violations show up in roadside inspection records and driver vehicle inspection reports.

Common cargo-related failures

• Insufficient tiedowns for the cargo's weight or shape
• Improper weight distribution — too much weight toward the front or rear axle
• Liquid load surge in tankers not equipped with baffles, or driven too aggressively for a partial load
• Overloading beyond the trailer's or tires' rated capacity
• Loose or falling debris from open trailers or improperly tarped loads

Who can be held liable?

• The cargo shipper or loader — often a separate company from the carrier, directly liable for negligent loading
• The trucking company — responsible for verifying securement before dispatch and en route
• The driver — required to inspect the load and refuse to drive an unsafe trailer
• A third-party logistics or freight brokerage — in some cases, for selecting an unqualified loader

Bills of lading, loading dock records, and weigh-station data help establish who packed and inspected the load. A big rig truck accident lawyer will pull this paper trail alongside the carrier's maintenance and dispatch records — see FMCSA regulations & evidence and who else can be held liable.
