Lancaster sits at the crossroads of State Route 14 and State Route 138, where high-speed desert commuting meets dense urban traffic on corridors like Sierra Highway and Avenue J. Collisions on these routes often result in serious injuries requiring immediate decisions that shape your legal and financial recovery. Knowing what to do in the first hours after a crash protects both your health and your rights.

California law imposes strict reporting and evidence-preservation obligations. Missing a deadline or failing to document the scene can forfeit your ability to recover damages. This guide walks through each critical step, grounded in the statutes and procedures that govern car accident claims in Los Angeles County and tailored to the realities of driving in Lancaster.

Ensure safety and summon emergency help

Your first duty is to stop at the scene. Leaving can trigger hit-and-run liability even if you were not at fault. Check yourself and passengers for injuries, then assess occupants of other vehicles. If anyone complains of pain, shows visible injury, or loses consciousness, call 911 immediately. Antelope Valley Medical Center at 1600 West Avenue J is Lancaster's designated Level II trauma center and the primary destination for serious collision injuries in the Antelope Valley.

If vehicles block traffic on State Route 14 or another high-speed corridor, move them to the shoulder or a side street if you can do so safely. California law permits—and encourages—clearing disabled vehicles from travel lanes to prevent secondary collisions. Turn on hazard lights, set out flares or triangles if available, and stay clear of moving traffic while waiting for law enforcement. Do not apologize or admit fault; statements at the scene can be used against you later.

Exchange information and document the scene

Vehicle Code §16025 requires every driver involved in a collision to exchange name, address, driver's license number, vehicle registration, and insurance information. Photograph all documents rather than writing them down; this avoids transcription errors. Also photograph all vehicles from multiple angles, capturing damage, license plates, and the surrounding area. If the crash occurred at a known high-risk intersection—such as 10th Street West and Avenue J—document traffic signals, signage, and road conditions.

Collect contact information from witnesses. Independent accounts often prove decisive when the other driver later disputes fault. Take wide shots showing the entire scene, skid marks, debris fields, and sight-line obstructions. If the other driver lacks insurance or refuses to share information, note the refusal and obtain a police report. Do not leave until you have fulfilled the exchange requirement or law enforcement has documented the collision.

Comply with reporting deadlines

California imposes three overlapping deadlines. First, Vehicle Code §20008 requires a written report to the California Highway Patrol or local police within 24 hours if anyone is injured or killed. Second, Vehicle Code §16000 mandates filing an SR-1 Traffic Accident Report with the DMV within 10 days if the collision caused more than $1,000 in property damage to any one person or resulted in any injury or death. Failure to file the SR-1 triggers automatic suspension of your driver's license under Vehicle Code §16056.

Third, if a government entity may be liable—for example, a poorly maintained signal on Sierra Highway or a dangerous condition on State Route 138—you must file a formal government claim within six months under Government Code §911.2. That claim is a prerequisite to any lawsuit. The two-year personal injury statute of limitations under CCP §335.1 does not cure a missed government-claim deadline; the six-month clock runs independently and cannot be extended except in narrow circumstances involving minors or incapacity.

Local details

Any personal injury lawsuit arising from a Lancaster collision will be filed in Los Angeles Superior Court and assigned to the North District. Your case will be heard at the Michael D. Antonovich Antelope Valley Courthouse, located at 42011 4th Street West, Lancaster, CA 93534. This courthouse handles all civil litigation for the Antelope Valley, including Lancaster, Palmdale, and surrounding communities.

Lancaster's geography affects both collision patterns and claim logistics. State Route 14, the Antelope Valley Freeway, carries commuters between the high desert and the San Fernando Valley at high speed; rear-end and lane-change collisions are common. State Route 138 is a rural two-lane highway with head-on and rollover risk. Surface streets like Sierra Highway and 10th Street West see pedestrian and bicycle accidents as well as intersection collisions.

Serious injuries go to Antelope Valley Medical Center, a Level II trauma center at 1600 West Avenue J. Emergency-room records generated there become essential evidence of injury causation and severity. California is an at-fault state, meaning the driver responsible for the collision must compensate you for medical bills, lost wages, pain, and other damages—subject to pure comparative negligence, which reduces your recovery by your own percentage of fault.

Frequently asked questions

Do I need to call the police for a minor fender-bender in Lancaster?

You are not required to call police if no one is injured and all drivers exchange information under Vehicle Code §16025. However, you must still file an SR-1 with the DMV within 10 days if total damage exceeds $1,000. A police report can prevent later disputes over fault, so calling law enforcement is often prudent even for seemingly minor collisions.

What if the other driver has no insurance?

California requires minimum liability coverage of 30/60/15 as of January 1, 2025. If the at-fault driver is uninsured, you may file a claim under your own uninsured-motorist (UM) coverage if you purchased it. UM coverage must be offered by every California insurer and can only be declined in writing. You may also sue the uninsured driver directly, though collecting a judgment can prove difficult.

How long do I have to file a lawsuit after a Lancaster car accident?

CCP §335.1 gives you two years from the date of the collision to file a personal injury lawsuit. If a government entity is potentially liable—such as Los Angeles County or Caltrans—you must file an administrative claim within six months under Government Code §911.2 before any lawsuit is permitted. Missing either deadline generally bars recovery.

Should I accept the insurance company's first settlement offer?

Initial offers often undervalue your claim, especially before you have completed medical treatment or calculated lost earnings. California's pure comparative negligence rule allows recovery even if you share fault, but insurers may overstate your percentage to reduce their payout. Consult an attorney before accepting any offer or signing a release; once signed, you cannot reopen the claim.
