You were hit on the 5, the 605, the 105, or a busy street like Firestone Boulevard or Whittier Boulevard. Now you are hurting and an adjuster wants your story. This guide explains what to do after a car accident in Downey, Norwalk, or Whittier in 2026.
The short answer
Get checked by a doctor, get the report number, and do not give a recorded statement to the other driver's insurance company. The California Highway Patrol handles crashes on the freeways. On city streets, Downey and Whittier have their own police departments, while Norwalk is patrolled by the Los Angeles County Sheriff. You generally have two years to sue the at-fault driver, but only six months to file a claim if a bus, a city vehicle, or a dangerous public road was involved.
Who takes the report?
The agency depends on where the crash happened.
- Interstate 5, Interstate 605, and Interstate 105: the CHP.
- City streets in Downey, such as Lakewood Boulevard, Firestone Boulevard, and Florence Avenue: the Downey Police Department.
- City streets in Norwalk, such as Imperial Highway, Rosecrans Avenue, and Studebaker Road: deputies from the Sheriff's Norwalk Station, because Norwalk contracts with the county for police service.
- City streets in Whittier, including Whittier Boulevard, Painter Avenue, and Colima Road: the Whittier Police Department.
- Unincorporated areas like South Whittier: the Sheriff.
Before you leave, write down the officer's name and the report number. If no officer came and anyone was hurt, you must report the crash to the DMV within 10 days on form SR-1.
Why this corner of LA County sees so many crashes
Three freeways meet in a few miles. The Santa Ana Freeway (the 5), the San Gabriel River Freeway (the 605), and the Glenn Anderson Freeway (the 105) all come together around Downey and Norwalk. Drivers cut across lanes to reach exits, traffic stops without warning, and rear-end crashes follow. Our guide on being partly at fault explains how California splits the blame.
Big rigs on the 5 and the 605. Both freeways carry heavy truck traffic between the ports, the rail yards, and the Inland Empire warehouses. If a commercial truck hit you, the trucking company may share the responsibility, and its logs and onboard data need to be saved quickly.
Long commercial boulevards. Firestone in Downey, Imperial Highway in Norwalk, and Whittier Boulevard through Uptown Whittier run past shopping centers, schools, and restaurants. Left turns across several lanes and drivers pulling out of parking lots cause a lot of side-impact crashes.
Buses and the train. Norwalk is the end of the Metro C Line along the 105, and Norwalk Transit buses run across the area. A crash involving a public bus or a city vehicle has its own short deadline, covered below.
Where people get treated
Paramedics choose the hospital based on your injuries. Many people hurt in this area are taken to PIH Health Downey Hospital, PIH Health Whittier Hospital, or Kaiser Permanente Downey Medical Center. If you did not take the ambulance, see a doctor or urgent care within a day or two. A gap in treatment is the first thing an adjuster uses against you.
What to do this week
- Keep every appointment and follow your doctor's plan.
- Take photos of the cars, the intersection, and your injuries as they change.
- Ask nearby businesses about cameras. Gas stations and shopping centers on these boulevards often record over video within days.
- Report the crash to your own insurer. You must cooperate with your own company.
- Do not give a recorded statement to the other driver's insurer. Our guide on recorded statements explains why.
Your deadlines
California's Code of Civil Procedure 335.1 generally gives you two years from the date of the injury to file a lawsuit against the driver who caused it.
When a public agency is involved, the clock is much shorter. A crash with a Metro or Norwalk Transit bus, a city truck, a patrol car, or a road defect usually requires a written government claim within six months. A lawsuit over a crash in this area would be filed in Los Angeles County Superior Court, which has courthouses in Downey, Norwalk, and Whittier.
