California Court Clarifies Shipper Liability After Overheight Cargo Strikes Bridge

Herc moved for summary judgment, arguing that the carrier and driver—not the shipper—had the controlling legal responsibility to inspect and safely transport the load.

The trial court agreed. It relied in part on federal motor-carrier regulations, California vehicle law, and the shipper-carrier doctrine associated with United States v. Savage Truck Line, Inc.

Under the traditional Savage rule, a carrier generally bears primary responsibility for safe loading, while a shipper that performs the loading may remain responsible for defects that are hidden or latent.

The Court of Appeal concluded that this rule did not justify dismissing Caltrans's third-party negligence claim against Herc.

The Court of Appeal reversed the judgment based on the order granting summary judgment for Herc.

Its most important published holding was narrow: a carrier's loading responsibilities do not categorically immunize a shipper from a negligence claim brought by an injured third party.

Savage historically addressed allocation between a shipper and carrier. Caltrans was a third party, not a participant in that commercial relationship. The court also explained that California's comparative-fault system permits responsibility to be allocated among multiple actors based on their respective conduct.

California Civil Code section 1714 states the state's general duty-of-care rule. The published opinion concluded that the carrier regulations did not create an exception that automatically insulated a shipper from responsibility for its own conduct.⁴

The decision therefore allows the claim against Herc to continue. It does not resolve whether Herc breached a duty, caused the damage, or bears any ultimate share of fault.

The court did not excuse the carrier or driver. Federal regulation 49 C.F.R. section 392.9 provides that a driver may not operate a commercial motor vehicle unless its cargo is properly distributed and adequately secured, and it requires a driver to assure that condition before driving.²

California Vehicle Code section 35250 generally limits a vehicle and its load to 14 feet in height. It also states that a vehicle or load exceeding 13 feet, 6 inches may be operated only on highways deemed safe by the vehicle owner.³

Those rules imposed duties on the carrier and driver. But the court held that those duties did not themselves establish that a shipper could owe no independent duty for its own loading conduct.

The published opinion treated the commercial relationship between shipper and carrier as different from a negligence claim by someone outside that relationship.

No California state court had applied Savage to categorically defeat a third party's negligence claim against a shipper. The court concluded that the rule could not be used to shield a shipper from such a claim merely because the carrier also had loading and inspection duties.

That does not abolish Savage for every purpose. Contractual, indemnity, or allocation disputes between a shipper and carrier can present different questions from a third party's direct negligence claim.

No. Reversing summary judgment is not a final finding of negligence or liability.

The decision did not determine whether Herc breached a legal duty, whether its conduct caused the bridge damage, how fault should be allocated, or what damages may ultimately be recoverable.

The case returned to the trial court for further proceedings. The opinion also stated that the appellate court was not deciding the precise standard of care governing Herc's conduct, leaving that issue for the trial court on remand.

The opinion was certified for publication except Part E of the Discussion.

The precedential analysis in this article therefore relies on the published portions addressing the Savage rule, California comparative-fault principles, federal motor-carrier regulations, and Vehicle Code section 35250.

Part E contains the court's detailed Rowland duty analysis. Because that part was excluded from publication, this article does not present it as published precedent. The reversal and the case's return to the trial court remain part of the procedural history.

A transportation-loss investigation may depend on photographs of the equipment before transport and of the loaded trailer; equipment configuration; load-height measurements; bills of lading; pickup and delivery documents; driver inspection records; loading procedures; dispatch communications; GPS and route information; permits; equipment manuals; and post-loss communications.

Contracts between the shipper and carrier, indemnity provisions, and insurance information can also matter. Those agreements may affect risk allocation between commercial participants even when a third party's negligence claim presents a separate question.

Even a few inches can be decisive. The opinion states that the loaded boom lift stood approximately five inches higher than the bridge clearance.

Mahrouyan Law handles selected commercial property, equipment, and cargo damage matters involving transportation losses and related evidence-preservation issues.

The decision does not mean a shipper is always responsible, and it does not make a carrier's duties disappear.

Its practical lesson is that different participants may have different duties at the same time. California comparative-fault principles may then determine how responsibility is allocated based on the evidence.

For shippers, carriers, loaders, equipment owners, and insurers, early preservation of loading records, photographs, measurements, contracts, and communications can be especially important.

Questions about responsibility, contractual allocation, and recovery may also require business and commercial litigation analysis beyond the immediate transportation regulations.
