Load Shift
Definition
A load shift is freight moving from its loaded position inside a trailer or container during transit, such as pallets sliding, leaning or toppling, enough to change the load's stability or weight distribution.
In simple English
Something in the trailer moved on the road. If the truck handles differently, treat it as a safety problem first and a delivery problem second.
What it means
Federal cargo securement rules require freight to be contained, immobilized or secured so it cannot shift "to such an extent that the vehicle's stability or maneuverability is adversely affected."[1] A driver who loads or secures cargo also has to check it within the first 50 miles and again at each change of duty status or after 3 hours or 150 miles of driving, whichever comes first; a sealed load the driver was told not to open is an exception.[2]
A load that has only settled has compacted slightly and evenly. A load that has shifted shows leaning stacks, gaps between rows or weight bunched at one end. The second kind can move weight between axle groups: federal Interstate limits are 20,000 lb on a single axle and 34,000 lb on a tandem, with an 80,000 lb gross limit and the bridge formula on top.[3]
What to do on the road, and how a shifted load gets restacked, is covered step by step in load shifted in the trailer.
Why it matters
A shift can make a truck unstable, push one axle group over its limit, damage product and get the load refused at the door. Photos taken before anything is touched protect the driver, the carrier and the shipper later.
Example
An LTL trailer reaches a cross-dock with two pallets leaning against the side wall after a detour over a rough ramp. They are photographed where they stand, restacked on sound pallets, rewrapped and braced before the freight moves on.
