Elk Grove, CA (November 5, 2026) – The California Highway Patrol is investigating a crash on Highway 99 near Dillard Road that killed one person after a big rig hit two cars stopped on the shoulder.
According to CHP, a Mazda had broken down on the highway and was parked on the shoulder while its driver waited for roadside assistance. A family member had pulled up behind the Mazda to help.
While both cars sat on the shoulder, a big rig tractor traveling northbound in the far right lane drifted for an unknown reason, CHP said. The truck struck both vehicles.
Both parties were taken to the hospital, where the Mazda driver’s relative died. CHP confirmed the death and said the collision happened around 1:30 p.m. on November 5.
The big rig overturned after the crash, blocking a lane and the center divide, according to CHP. The blockage led to a traffic jam lasting nearly three hours.
CHP has not said what caused the truck to drift. The South Sacramento CHP office is actively investigating and has asked anyone who witnessed the crash or has relevant information to contact the office.
This is a developing story. Details may change as the investigation continues.
What Families Can Do After a Fatal Truck Crash in Elk Grove, CA
The National Highway Traffic Safety Administration reported 5,340 deaths in crashes involving large trucks nationwide in 2024. Seventy percent of those killed were occupants of other vehicles, not the trucks. Since January 1, 2026, California’s expanded Slow Down, Move Over law (Vehicle Code 21809) has covered any stopped vehicle showing hazard lights or other warning devices.
In the first days after a loss like this, a few practical steps can protect the family and the record of what happened:
- Contact the South Sacramento CHP office for the report number and the name of the investigating officer, so updates come from one source.
- Ask in writing that neither car be released, crushed, or sold for salvage until the family has had a chance to have it inspected.
- Write down anything known about the truck, such as the company name or the USDOT number painted on the cab door.
- Choose one person in the family to take insurance calls, and keep notes on every conversation, including names and dates.
- Request several certified copies of the death certificate, since banks, insurers, and courts often ask for originals.
- Hold off on posting about the crash on social media while the investigation is still open.
For the driver who survived, ongoing medical follow-up matters too. Keep every discharge paper and appointment record from the hospital stay.
Trucking Company Liability After a Big Rig Crash on Highway 99
When a tractor-trailer leaves its lane and hits vehicles stopped on the shoulder, the claim rarely ends with the driver. Federal and state rules make the trucking company responsible for how its drivers are hired, trained, scheduled, and supervised. A carrier is also usually responsible for a driver’s conduct while that driver is working.
CHP has said the truck drifted for an unknown reason. In crashes like this, investigators commonly look at driver fatigue, distraction, a medical event, or a mechanical failure such as steering or tires. Each of those can point to a different responsible party, so the cause shapes the whole case.
Two kinds of claims may follow a death in California. A wrongful death claim lets close family members recover for the loss of their loved one’s support, care, and companionship. A survival claim, brought by the estate, covers losses the person suffered before death, along with medical and funeral costs.
- Who may be liable: the truck driver, the motor carrier that employed or contracted the driver, the owner of the tractor or trailer, a company that loaded the cargo, or a shop that maintained the truck.
- What evidence decides it: the truck’s electronic logging device and engine control module data, hours-of-service records, the driver qualification file, maintenance and inspection logs, and any dashcam video. Much of this can be lost if no one asks for it early.
- Comparative fault: California uses pure comparative fault. Even if an insurer argues that where the cars were stopped played a role, the family can still recover, reduced only by any share assigned to them.
- Filing deadline: wrongful death and injury lawsuits generally must be filed within two years (Code of Civil Procedure 335.1 and 377.60). For a death and crash on November 5, 2026, the deadline is November 5, 2028.
