You were moving through traffic on the 101 somewhere between the Lost Hills Road exit and the Las Virgenes Road interchange, and then someone hit you from behind. Your car got shoved forward. Your neck snapped back. Now you're sitting on the shoulder with your hazard lights on, hands shaking, trying to figure out what just happened and what you're supposed to do next.

This guide is for right now.

The 101 through Calabasas is a specific kind of dangerous. Traffic piling up near the Lost Hills Road ramps slows suddenly while drivers coming over the Agoura Hills grade are still at speed. That mismatch is exactly how rear-end collisions happen here. The physics of a 10-mph impact are enough to cause soft-tissue injuries that won't announce themselves until the next morning, sometimes the morning after that.

California Highway Patrol has jurisdiction on US-101. Once you exit the freeway onto Las Virgenes Road or Lost Hills Road, you're dealing with LASD Lost Hills Station, not LAPD. Calabasas isn't part of the City of Los Angeles, which means LAPD never responds here. Who shows up to your accident matters for where the report lives and who controls the evidence.

What to Do Right Now, Step by Step

Step 1: Get to the right shoulder. If your car moves, get off the 101 travel lanes immediately. The stretch between the Lost Hills and Las Virgenes exits has limited emergency pull-outs. Secondary crashes on California freeways are a serious risk. Hazard lights on, stay in the vehicle if you're on the main lanes until CHP arrives.

Step 2: Call 911. On the 101, this brings CHP. Do not skip this because the crash looks minor. A CHP report establishes the scene, the parties, and the officer's preliminary assessment of what happened. Without it, the other driver's insurer has far more room to dispute fault and minimize your claim. When CHP arrives, give them the facts and only the facts. What you saw, what you felt, where you were. Don't speculate about fault at the scene.

Step 3: Document before anything moves. If it's safe, photograph the damage to both vehicles, license plates, skid marks, and the surrounding freeway. If you can get the Lost Hills Road or Las Virgenes Road signs in the frame, that places the crash geographically in a way that helps later when you're dealing with adjusters. Note where between exits this happened.

Step 4: Exchange information, say nothing about fault. Get the other driver's name, license number, insurance company, and policy number. Give yours. Do not say "I'm fine," "I'm sorry," or "I don't think I'm hurt." These phrases get recorded and used against your claim. Adrenaline is masking pain right now. You don't know yet how you feel.

Step 5: Go to West Hills Hospital and Medical Center. This is the closest emergency facility to this stretch of the 101. West Hills Hospital is at 7300 Medical Center Drive in West Hills, roughly 10 to 15 minutes east of the Calabasas area via the 101. Don't wait until tomorrow. A same-day emergency evaluation creates a medical record that directly links your injuries to the crash date. If you wait two days because you "felt okay," the insurance company will exploit that gap. They do this routinely.

Step 6: Notify your own insurer. You're required to report the accident under your policy. Keep it factual and brief. The other driver's insurance company is a different situation - do not give them a recorded statement before speaking with an attorney.

Step 7: Document every symptom that follows. Keep a written log. Date, what you felt, severity. Missed work, trouble sleeping, headaches, stiff neck, shoulder pain - all of it is potentially compensable, but only if it's documented from the start.

California Law on Rear-End Collisions

In California, the driver who rear-ends another vehicle is presumed to be at fault. California Vehicle Code requires every driver to maintain a safe following distance. That presumption can be overcome in limited circumstances, but in the vast majority of rear-end crashes on the 101, liability sits with the driver who hit you.

California follows pure comparative fault. Even if you're found partly responsible, your compensation is reduced by your percentage of fault, not eliminated. Rear-end crashes rarely involve shared fault, but it does come up occasionally when brake lights were malfunctioning or when someone stopped suddenly without warning.

You have two years from the accident date to file a personal injury lawsuit. Cases from crashes on the 101 near Calabasas are handled at the Chatsworth Courthouse, which serves the West San Fernando Valley and the Conejo area. Two years sounds comfortable, but traffic camera footage on freeway corridors is typically overwritten within a week or two. Witness contact information evaporates fast. The sooner you move, the better the evidence.

If you're ready to understand what your claim is worth, talking with a Calabasas car accident lawyer now protects the evidence and your legal options.

What Compensation You Can Recover

Rear-end crashes on the 101, including ones that look minor from the outside, regularly produce significant injury claims. Here's what the compensation can include:

Medical expenses: Emergency room at West Hills Hospital, imaging, specialist visits, physical therapy, chiropractic care, prescriptions, and future treatment your doctors say you'll need. Future medical costs are often the largest component.

Lost wages: Every day you couldn't work because of your injuries. If your injuries affect your ability to do your job long-term, lost earning capacity goes into the calculation too.

Pain and suffering: California allows recovery for physical pain, emotional distress, and loss of enjoyment of life. The severity and duration of your symptoms matter significantly here.

Property damage: Repair costs or fair market value of your vehicle, plus rental car expenses.

For whiplash, herniated discs, or nerve damage, which are common outcomes in higher-speed rear-end crashes near the Lost Hills interchange, total compensation can reach well into six figures. The number depends on injury severity, how clearly liability is established, and the at-fault driver's coverage limits.

Don't Let Time Slip Away From You

The most common mistake people make after being rear-ended on the 101 is telling themselves they'll deal with it later. Two days pass, the neck stiffens, and the other driver's insurance company has already built a file that supports a low offer. Evidence on the freeway is gone. Witnesses have moved on.
