Marin County and California-wide representation for people seriously injured in collisions with commercial trucks, delivery vehicles, and government fleet vehicles. Synergist Law, P.C. is a boutique California personal injury firm led by Sami Sedghani, Pharm.D., J.D. Commercial vehicle collisions are a materially different category from passenger-vehicle cases — higher insurance coverage, federal regulatory overlays, multiple liable defendants, and preserved electronic evidence that disappears if not demanded within days.

Why California commercial truck cases are different

A collision between a passenger vehicle and a loaded 80,000-pound tractor-trailer produces injury patterns rarely seen in car-on-car crashes. Beyond the physics, four structural factors change the case entirely:

  • Higher insurance coverage. Federal motor-carrier minimums alone are $750,000 under 49 CFR Part 387, and many carriers maintain $1 million to $5 million or more.
  • Federal regulatory overlay. Commercial defendants are subject to the Federal Motor Carrier Safety Regulations (FMCSR, Title 49 CFR Parts 350–399). Violations support negligence-per-se arguments.
  • Preserved electronic evidence. Commercial vehicles produce ELD, EDR/ECM “black box”, telematics, and dashcam data that passenger vehicles do not — and that is overwritten quickly without a spoliation letter.
  • Multiple potentially liable defendants. Driver, motor carrier, broker, shipper, trailer owner, maintenance contractor, and vehicle/parts manufacturers can all be in the case.

Types of California truck and commercial vehicle cases we handle

  • Tractor-trailer / 18-wheeler / big-rig collisions
  • Delivery vehicle collisions — FedEx Ground and Freight, UPS, Amazon Delivery Service Partners (DSPs), OnTrac, and regional last-mile carriers
  • Box truck and straight-truck collisions
  • Rental and moving truck collisions — U-Haul, Penske, Budget, Ryder
  • Construction and dump truck collisions
  • Garbage/waste hauler collisions
  • Tanker and hazmat vehicle collisions
  • Caltrans and government fleet vehicle collisions — subject to the six-month Government Claims Act deadline under Gov. Code § 911.2
  • USPS vehicle collisions — governed by the Federal Tort Claims Act
  • Commercial bus collisions — Marin Transit, Golden Gate Transit, intercity, charter
  • Truck-on-pedestrian and truck-on-cyclist collisions
  • Wrongful-death commercial vehicle cases

Who can be held liable in a California truck accident case

  • The driver
  • The motor carrier (employer) — vicariously liable under respondeat superior and directly liable for negligent hiring, training, supervision, retention; vehicle maintenance; and safety enforcement
  • The trailer owner — for defects or improper cargo securement
  • Brokers and shippers — for negligent selection of an unsafe carrier or improper loading
  • Vehicle and parts manufacturers
  • Maintenance contractors
  • Governmental entities — if a dangerous condition of public property contributed

Last-mile delivery cases: FedEx, UPS, Amazon DSP, OnTrac

  • UPS — directly employs its drivers; respondeat superior applies straightforwardly.
  • FedEx Ground / FedEx Freight — historically used independent-contractor structures. Current operations vary by region.
  • Amazon — uses Delivery Service Partners (DSPs), nominally independent contractors. Amazon’s direct liability turns on operational-control facts and its safety and training policies.
  • OnTrac and other regional carriers — each has its own structure.

The correct corporate defendant is often not obvious from the truck’s branding. Identifying the right defendants, piercing contractor structures where facts support it, and preserving the right electronic evidence are the early tasks that distinguish results.

Electronic evidence — what gets lost without a spoliation letter

  • Electronic Logging Device (ELD) data — hours of service, mandatory under 49 CFR Part 395. Overwritten on rolling cycles.
  • Event Data Recorder (EDR) / Engine Control Module (ECM) data — speed, braking, throttle, airbag deployment events
  • Telematics data — Omnitracs, Samsara, Lytx, Motive
  • Dashcam footage — forward and driver-facing cameras with limited retention windows
  • Driver qualification files, drug/alcohol testing records, FMCSA SAFER data
  • Vehicle maintenance and inspection records
  • Dispatch, routing, and load records

Government vehicle collisions — short deadlines

  • California public entities — Gov. Code § 911.2 requires a written claim within six months of accrual.
  • USPS and other federal agencies — the Federal Tort Claims Act requires an administrative claim within two years of accrual.

Missing either deadline typically bars the claim entirely regardless of merit. The six-month California deadline can expire before an injured person has completed initial medical treatment.

California statute of limitations for truck accident claims

Private-defendant personal injury: two years under California Code of Civil Procedure § 335.1. Wrongful death: two years from date of death. Property damage: three years. Public entity: six months (Gov. Code § 911.2). Federal fleet: two years (FTCA).

Why Synergist Law for serious truck accident cases

  • Direct attorney involvement from intake forward. Sami handles discovery, depositions, and expert workup personally.
  • Clinical fluency. Doctor of Pharmacy (UCSF) before law school. Truck-accident polytrauma — TBI, spinal cord, orthopedic, chronic pain — demands plaintiff counsel who can cross-examine on the medicine.
  • Published appellate experience. Osaze v. Aparicio-Gee (First District, Division Two, September 2026) — insurance defense counsel can see on the appellate record whether a firm actually tries and appeals cases.
  • Boutique caseload. Fewer cases; substantially more attorney time per matter than a volume firm.

Common injuries in California truck accident cases

Damages recoverable in a California truck accident case

  • Economic damages — past and future medical expenses (often documented in a life care plan), lost wages, lost earning capacity, property damage
  • Non-economic damages — pain and suffering, emotional distress, disfigurement, loss of enjoyment of life, loss of consortium
  • Punitive damages — under Civil Code § 3294 where motor-carrier conduct rose to fraud, malice, or conscious disregard for safety

What to do after a truck accident in Marin County

  1. Call 911.
  2. Note the truck’s USDOT number, carrier name, and license plate. Photograph the trailer branding and the cab separately — they are often different companies.
  3. Photograph the scene — damage, final rest, debris, skid marks, cargo spill.
  4. Get witness information.
  5. Preserve nearby surveillance footage — gas stations, warehouses, commercial lots along the corridor.
  6. See a doctor the same day.
  7. Do NOT give a recorded statement to the motor carrier’s insurer.
  8. Contact an attorney immediately. Spoliation letters need to go out within days to preserve ELD, EDR, telematics, dashcam, and driver records.

Frequently asked questions about California truck accident cases

How is a truck accident different from a car accident?

Higher coverage, federal regulatory overlay (FMCSR), preserved electronic evidence that passenger vehicles don’t produce, and multiple liable defendants beyond the driver.

Six months for California public entities under Gov. Code § 911.2. Two years for federal (USPS) under the FTCA.
