California is an at-fault state, so the driver who caused the accident is generally responsible for the damage. You notify your insurance company promptly, an adjuster investigates and inspects your vehicle, and California regulations give insurance companies hard deadlines: 15 calendar days to acknowledge your claim, 40 days to accept or deny it after receiving proof of claim, and written updates every 30 days if it drags. You pick the repair shop, not them.
Nobody reads their auto insurance policy until they’re involved in a car accident and have to file an insurance claim. Then suddenly there’s an insurance adjuster on the phone using words like “proof of loss” and “subrogation,” your car is at a tow yard accruing fees, and you’re trying to work out whether to file a claim with your own carrier or the other driver’s insurance company.
Let’s slow it down. A car accident insurance claim in California follows a fairly predictable path, and most of the stress comes from not knowing what happens next or how long each part should take. The good news is that California regulates this more tightly than most states, and there are specific things insurance companies are legally required to do on a specific schedule. Very few drivers know that, which is a shame, because it’s the most useful information available.
We’re not an insurance company and we don’t give insurance advice. We help California drivers get their cars repaired, so we sit alongside this process daily and see where it flows and where it snags. What follows is general information about accident insurance claim mechanics in this state, written to help you ask better questions of the people who can actually advise you.
How Does a Car Accident Insurance Claim Work in California?
California uses a fault-based system, meaning the at-fault driver’s insurance is generally responsible for the resulting damage. You report the accident, an adjuster investigates and assigns fault, your vehicle gets inspected and estimated, and the claim resolves through repair payment, a total loss settlement, or a denial you can dispute.
The accident claim process has more moving parts than people expect, partly because two claims often run at once. There’s the property damage side, which is your car, and there’s the injury claim side if anyone was hurt. They frequently move at different speeds and sometimes involve different adjusters at the same company.
Fault gets divided rather than assigned wholesale. California follows comparative negligence, so if you share fault in an accident, your recovery is reduced by your percentage rather than eliminated. Being 20% at fault for the accident doesn’t end your claim; it trims it. Worth knowing too that California is not a no-fault state, so personal injury protection, the coverage some other states use, isn’t part of the picture here. Medical payments coverage, or MedPay, is the optional California equivalent for medical bills regardless of fault.
Should You File With Your Insurance or Theirs?
You can generally do either, and often both. Filing a claim with your insurance company is usually faster since you have a contract with your insurance provider, and you control when you file the claim, while a third-party claim against the at-fault driver’s insurance company avoids your deductible but depends on their carrier accepting liability.
Here’s the practical tradeoff on a car accident insurance claim, and it’s the question we hear most. Going through your own collision coverage typically gets your car into a shop sooner, because your insurer owes you a duty under your policy and doesn’t have to wait for the other side to admit anything. You pay your deductible up front. If your insurer later recovers from the at-fault carrier through subrogation, that dollar amount usually comes back to you.
Claiming against another driver’s carrier means no deductible, but you move at their pace. If they’re disputing who caused the accident, that pace can be glacial while your car sits. Neither route is automatically right, which makes it exactly the sort of question to put to your own insurance agent, since they know your actual coverage.
Whatever you choose, notify your insurance company either way. Most California policies require prompt notice of any accident, and staying quiet because you plan to claim against the other side can create a problem you didn’t need.
How Insurance Works After a Car Accident, Step by Step
Understanding how insurance works after a car accident is mostly about sequence. Each stage has a purpose, and knowing what comes next makes the waiting far less maddening.
Roughly how it unfolds:
- You report a claim. A phone call, a mobile app submission, or filing your claim online all work, and you’ll get a claim number everything else hangs off.
- An adjuster gets assigned and reaches out, usually within days. They’ll want your account of the circumstances of the accident, the police report number if you have one, and photos.
- Your vehicle gets inspected. Sometimes an appraiser sees it in person, sometimes a shop’s photos and estimate suffice, sometimes you upload pictures.
- Liability gets sorted. Adjusters compare accounts, review the accident report and evidence, and reach a fault determination, which is where comparative negligence percentages appear.
- A repair estimate becomes an authorization, or the car is declared a total loss if repair costs approach its value.
- Payment goes out, to you or directly to the auto repair shop, minus your deductible if you went through your own collision coverage.
Supplements are normal here. The first estimate is written from what’s visible, and once a shop pulls the bumper cover, hidden vehicle damage frequently turns up. That triggers a supplemental estimate and another approval round, which is routine rather than a sign something went wrong.
What Information You Need to Start the Claims Process
Have your policy number, the other driver’s insurance information, and your documentation ready before you call. Gathering it first turns a frustrating call into a short one.
The adjuster will ask for information about the accident and about everyone involved in the accident, so to start the claims process you’ll generally want your own insurance card and policy number, the other party’s insurance company name and policy number from their insurance card, their driver’s license and license plate number, the make and model of all vehicles involved, the date, time, and location of the accident, and the police report number. If you worked from an accident checklist at the accident scene, most of this is already in your notes. Photos of the scene and every angle of damage round it out, and having the license plate alone can resolve a surprising number of identification questions later.
What Deadlines Does Your Insurer Have to Meet?
California’s Fair Claims Settlement Practices Regulations bind insurance companies to specific timeframes. They must acknowledge your claim within 15 calendar days, accept or deny it within 40 calendar days of receiving proof of claim, and provide written status updates every 30 days while it stays open.
This is the part almost nobody tells drivers, and it changes how you handle a slow car accident insurance claim. Under Title 10 of the California Code of Regulations, section 2695.5, an insurer receiving notice has 15 calendar days to acknowledge it, provide necessary forms and instructions, and begin any needed investigation. Section 2695.7 then requires the insurer to accept or deny, in whole or in part, within 40 calendar days of receiving proof of claim.
If they need longer, they can’t simply go quiet. The insurance company may extend, but must notify you in writing before those 40 days expire, explain what additional information it needs, and keep sending written updates every 30 days until it decides. Accepted amounts are supposed to be paid promptly.
So when things stall, you’re not stuck asking politely and hoping. You can ask for the status of your claim in writing, reference the timeline, and escalate to the California Department of Insurance if answers don’t come. Filing a complaint with the Department of Insurance is free, and knowing that option exists tends to change conversations. We can’t advise whether your particular situation involves a violation; a licensed attorney can, and can also tell you whether it makes sense to file a lawsuit.
What Rights Do You Have Over the Repair?
More than most drivers realize. California’s Auto Body Repair Consumer Bill of Rights guarantees that you select the shop, that an insurer cannot require repairs at a specific facility, and that you receive an itemized written estimate and a detailed final invoice.
That last piece is genuinely useful leverage. Under the Bill of Rights, your estimate and invoice must include an itemized list of parts and labor with the total price, and must identify every part as new, used, aftermarket, reconditioned, or rebuilt. So if you want to know whether your repair process involves original equipment parts or aftermarket ones, you don’t have to wonder. It’s required to be on the paperwork.
A few other entitlements worth knowing:
- You can obtain an independent estimate directly from a registered auto body shop, even while pursuing a claim on that vehicle. An adjuster’s number isn’t the only number that exists.
- You’re entitled to be informed about coverage for towing and storage, which matters more than people expect when a car sits in a lot billing daily.
- You’re entitled to be told what rental car coverage you have, if any, while the vehicle is being repaired.
- Insurance companies are required to provide this Bill of Rights to policyholders, either when the policy is issued or following a reported accident, so it may already be sitting in your email.

What Slows a Claim Down, and What You Can Control
Disputed fault is the biggest delay, followed by incomplete documentation and hidden damage found mid-repair. You can’t control the first, but the second is almost entirely in your hands.
Adjusters work from evidence, and a car accident insurance claim with clear photos from the scene of the accident, a police report number, and a coherent written account moves faster than one built on a phone conversation. Everyone involved in an accident should call the police when they reasonably can, because if nobody did at the time of the accident, that gap shows up here, even after a modest auto accident. Nothing you do later replaces a photo you didn’t take.
A few other friction points we see when filing an auto claim California drivers run into regularly. Storage fees pile up while liability gets argued, so moving your car to a shop early saves real money. Recorded statements to the other side can wait until you’ve caught your breath. And a quick settlement offer landing before your car has been fully inspected is worth pausing on, since accepting closes doors that hidden damage might later need open.
Frequently Asked Questions
How long does an insurance company have to settle a claim in California?
Insurance companies must acknowledge a claim within 15 calendar days and accept or deny it within 40 calendar days of receiving proof of claim, under California’s Fair Claims Settlement Practices Regulations. If more time is needed, they must explain in writing and update you every 30 days.
Do I have to use the repair shop my insurance recommends?
No. California’s Auto Body Repair Consumer Bill of Rights states a consumer may select the auto body shop, and an insurance company shall not require repairs be done at a specific shop. Adjusters may recommend one, but the choice is yours.
Will filing a claim raise my rates if I wasn’t at fault?
California ties surcharges to fault determinations, so a not-at-fault claim generally shouldn’t trigger one on that basis alone. Some car insurance company underwriting still weighs overall claim history at renewal, so ask your agent about your specific policy.
What happens if my auto insurance claim is denied?
Request the denial in writing with the specific reason, then gather documentation addressing it, such as a supplemental estimate or added evidence on liability. You can dispute it with the insurer and file a complaint with the California Department of Insurance. For disputed liability or injuries, consult a licensed attorney.
How long do I have to file a car accident claim in California?
Notify your insurer promptly, since most policies require it. For lawsuits, California generally allows two years from the injury date for personal injury and three years for property damage, and claims involving a government entity can require notice within six months.
Does my insurance pay if the other driver is uninsured?
Uninsured or underinsured motorist coverage is designed for exactly that, and California requires insurance companies to offer it, though drivers may decline in writing. An uninsured motorist claim runs through your own policy, so check your declarations page for which types of insurance you actually carry.
Who pays my deductible in a car accident insurance claim?
You pay it when claiming through your own collision coverage. If your insurer recovers from the at-fault driver’s insurance company through subrogation, your deductible is typically reimbursed, in whole or in part, depending on how fault was allocated.
Do I need to report the accident to the DMV too?
Often yes, and it’s separate from your claim. The California Department of Motor Vehicles requires an SR-1 within 10 days when a crash causes any injury, death, or more than $1,000 in property damage, regardless of fault. Your liability insurance carrier won’t file it for you.
Getting Your Car Moving While the Claim Works Itself Out
Claims run on their own clock, and there’s a real limit to how much you can speed one up. What you can control is your half: document thoroughly, respond quickly when the adjuster asks for something, know the deadlines your insurer must meet, and remember the repair decision belongs to you. A car accident insurance claim goes considerably smoother once you know which parts are actually negotiable.
