You were hit on the 14, the 5, or a city street in Santa Clarita, Palmdale, or Lancaster. You are sore, your car is in a tow yard, and an adjuster wants to talk. This guide covers what to do next in North Los Angeles County in 2026.
The short answer
Get medical care, get the report number, and do not give a recorded statement to the other driver's insurer. The California Highway Patrol handles crashes on the freeways and on county roads. The Los Angeles County Sheriff's Department usually handles crashes on city streets in all three cities, because Santa Clarita, Palmdale, and Lancaster contract with the Sheriff for police service. You generally have two years to sue the other driver, but only six months to file a claim if a public agency played a part.
Who takes the report in North LA County?
The agency depends on the road, not the city name on your mail.
- Interstate 5, Highway 14, Highway 126, and Highway 138: the CHP. Santa Clarita Valley freeway crashes usually fall to the CHP's Newhall office, and Antelope Valley crashes to its Antelope Valley office.
- Unincorporated areas, such as Castaic, Stevenson Ranch, Acton, Agua Dulce, Lake Los Angeles, and Littlerock: usually the CHP.
- City streets in Santa Clarita, Palmdale, and Lancaster: sheriff's deputies from the local station.
Ask for the report number before you leave the scene. If no officer came and anyone was hurt, you still must report the crash to the DMV within 10 days on form SR-1.
What makes Santa Clarita Valley crashes different
The Newhall Pass, where the 5 and the 14 meet, is one of the busiest freeway junctions in the county. Merges are short, traffic stacks up fast, and rear-end crashes are common at rush hour.
Truck traffic is heavy on the 5 through Castaic and up toward the Grapevine. If a big rig hit you, the trucking company may share responsibility with the driver. Our truck accident lawyers can send a preservation letter so the driver logs and camera footage are not erased.
Canyon roads add their own risks. Bouquet Canyon, San Francisquito Canyon, and Soledad Canyon have tight curves, few shoulders, and drivers who take them too fast.
What makes Antelope Valley crashes different
Palmdale and Lancaster sit in the high desert, where long, straight roads invite speeding.
Highway 138, including Pearblossom Highway, is a two-lane road for much of its length. Head-on and passing crashes are a real danger. Sierra Highway and Avenue roads at the edge of town can be dark at night, with long gaps between signals.
The desert brings weather too. Strong wind and blowing dust can cut visibility on the 14 and the open roads around it. Like fog or rain, bad conditions do not excuse a driver. The law requires every driver to slow down for what they can see, and one who does not can still be at fault.
What to do in the first week
- Get checked out. Neck, back, and head injuries often feel worse two or three days later.
- Keep treating. Gaps in care are the first thing an adjuster points to.
- Photograph everything. The cars, the road, skid marks, and your injuries as they change.
- Look for cameras. Gas stations, shopping centers, and doorbell cameras may have caught the crash.
- Tell your own insurer. Your policy requires you to cooperate with your own company.
- Skip the recorded statement. Our guide on recorded statements to the adjuster explains why that call can hurt you.
Your deadlines
Under Code of Civil Procedure 335.1, you generally have two years from the date of the injury to file a lawsuit against the at-fault driver.
The clock is much shorter when a public agency is involved. A crash caused by a dangerous road, a broken signal, or a sheriff's, city, or county vehicle usually requires a written government claim within six months. A lawsuit over a crash in North LA County would generally be filed in Los Angeles County Superior Court.
