Background
Herc Rentals employees loaded an articulating boom lift onto a carrier’s flatbed truck without lowering its extended arm. The driver did not measure the load. At 15 feet 6 inches, the lift struck a Caltrans overcrossing with 15 feet 1 inch of clearance and damaged the bridge.
Caltrans sued Herc, the carrier, and the driver for negligence. Herc obtained summary judgment on the theory that federal transportation law and the shipper-carrier rule placed responsibility for safe loading on the carrier. Caltrans appealed, arguing that Herc remained responsible for its own role in providing and loading an obviously dangerous configuration.
The Court’s Holding
The First District reversed. The traditional rule assigning primary cargo responsibility to a carrier does not create categorical immunity for a shipper under California’s comparative-fault system. Federal regulations and the Vehicle Code impose duties on carriers and drivers, but they do not expressly eliminate a shipper’s ordinary duty to use reasonable care.
Applying the factors California courts use to decide whether to create an exception to the general negligence duty, the court found no basis for exempting shippers. Herc controlled and understood its equipment, the bridge damage was foreseeable, and requiring reasonable care in providing or loading cargo was not unduly burdensome. The court left the precise standard of care and allocation of fault for remand.
Key Takeaways
- A carrier’s statutory loading duties do not necessarily displace a shipper’s common-law negligence duty.
- California comparative fault permits responsibility to be allocated among the shipper, carrier, and driver.
- Businesses loading specialized equipment should document its transport configuration, height, and handoff checks.
- Summary judgment is risky where the shipper’s own loading choices may have created the hazard.
Why It Matters
Equipment lessors, manufacturers, warehouses, and logistics companies cannot assume that hiring a motor carrier transfers all loading risk. A shipper with superior knowledge and physical control of its cargo may face direct liability to motorists or public agencies injured by unsafe loading.
Contracts and insurance still matter, but they do not erase duties owed to third parties. California businesses should align loading protocols, measurements, photographs, and responsibility matrices with the practical reality that several participants may share fault.
