What California requires you to carry
California law requires every driver to carry liability insurance before operating a vehicle on public roads. Liability coverage pays for damage or injuries you cause to someone else — not damage to your own car. The state's minimum limits are 15/30/5: $15,000 per person injured, $30,000 per accident, and $5,000 for property damage.
These minimums are low enough that most drivers carry more. A single accident causing serious injury can easily exceed $15,000, leaving you personally responsible for the rest. Many insurers recommend 100/300/100 or higher, and some employers or lenders require it as a condition of doing business with you.
You do not have to carry collision or comprehensive coverage — insurance for damage to your own vehicle — unless your car is financed or leased. If you own the car outright, you can legally choose to carry only liability. If you have a loan or lease, your lender will require both collision and comprehensive as a condition of the loan agreement.
Key Takeaways
- California's minimum liability coverage is 15/30/5, but these limits often leave you personally responsible for costs above them.
- Collision and comprehensive coverage are optional if you own your car outright, but required by lenders if you have a loan or lease.
- Your insurer can drop you for non-payment or fraud, but cannot cancel for a single accident or traffic ticket without advance notice.
- If you drive without insurance, California suspends your license and registration, and you must file an SR-22 form to restore them.
- Rates vary widely by age, driving record, location, and vehicle type — shopping between insurers can save hundreds per year.
How rates are set and what affects your premium
California insurers use a formula that weighs your driving record most heavily, followed by age, location, and the vehicle you drive. A single at-fault accident or moving violation can raise your rate by 20 to 40 percent for three to five years. Drivers under 25 and over 65 pay significantly more because statistics show they have higher accident rates.
Where you live matters because urban areas have higher theft and accident rates than rural ones. Your ZIP code can shift your premium by hundreds of dollars per year. The type of vehicle also affects cost — a sports car costs more to insure than a sedan, and a newer car with expensive parts costs more than an older one.
California prohibits insurers from using gender, marital status, or credit score to set rates, though some states allow these factors. Insurers can use your prior insurance history — whether you had a lapse in coverage or switched companies frequently — but cannot penalize you for being a new driver or for not having prior insurance.
What happens if you drive without insurance
Driving without liability insurance in California is a misdemeanor. If you are stopped by police, you face a fine of $100 to $250 for a first offense, plus court costs. More importantly, the California Department of Motor Vehicles will suspend your driver's license and registration when ready upon notice of an uninsured accident or conviction.
To restore your license after suspension, you must file an SR-22 form with the DMV. This is a certificate from your insurer stating that you now carry the state minimum. You must maintain continuous coverage for three years without a lapse. If your coverage lapses even for one day, the DMV is notified and your license is suspended again.
If you cause an accident while uninsured, you are personally liable for all damages. The other driver can sue you directly, and a judgment can follow you for years through wage garnishment or bank levies. Many uninsured drivers end up paying far more in the long run than they would have spent on insurance premiums.
How insurers can cancel or non-renew your policy
California law limits when an insurer can cancel your policy. They can cancel for non-payment, but must give you 10 days' notice. They can cancel for fraud — lying on your process or filing a false claim — but must provide written notice and a reason. They cannot cancel you straightforward because you had an accident or received a traffic ticket.
Insurers can choose not to renew your policy when it expires, but only for specific reasons: non-payment, fraud, a major violation like driving under the influence, or if you misrepresented facts material to the risk. They must give you 60 days' notice before non-renewal and must state their reason in writing. If you dispute the reason, you can request a hearing with the California Department of Insurance.
If your insurer cancels or non-renews you, you may still be able to find coverage through the California FAIR Plan, which is a pool of last-resort insurers. Coverage through the FAIR Plan costs more than standard insurance, but it ensures you can maintain the liability coverage required by law.
Discounts and ways to lower your premium
Most California insurers offer discounts for bundling auto and home insurance, maintaining a clean driving record for three to five years, completing a defensive driving course, and installing anti-theft devices. Some offer usage-based discounts if you allow them to monitor your driving through a mobile app or plug-in device. These discounts typically range from 5 to 25 percent, though the exact amount varies by insurer.
Low-mileage discounts are available if you drive fewer than a certain number of miles per year — usually 7,500 to 10,000. If you work from home or use public transit most days, this discount can be substantial. Some insurers also offer discounts for paying your premium in full upfront rather than monthly, or for setting up automatic payments.
The most effective way to lower your rate is to shop between insurers every two to three years. Rates for the same coverage can differ by $500 or more annually between companies. Getting quotes from at least three insurers takes less than an hour and can reveal significant savings. Many insurers offer online quote tools that do not require a phone call.
Uninsured and underinsured motorist coverage
Uninsured motorist coverage pays for your injuries if you are hit by a driver who has no insurance. Underinsured motorist coverage pays the difference if the at-fault driver's liability limits are too low to cover your damages. California does not require either, but they are inexpensive add-ons that protect you against drivers who break the law.
Uninsured motorist coverage typically costs $10 to $30 per month and covers medical bills, lost wages, and pain and suffering up to your chosen limit. Underinsured motorist coverage is usually only slightly more. Together, they fill a gap that liability insurance alone cannot cover — the gap created by other people's failure to carry adequate coverage.
If you are injured by an uninsured driver and do not have uninsured motorist coverage, your only recourse is to sue the driver directly. Most uninsured drivers have few assets, so a judgment against them may be uncollectible. Having uninsured motorist coverage avoids this problem entirely.
How to file a claim and what to expect
After an accident, contact your insurer as soon as possible — most require notice within 24 to 72 hours. Provide your policy number, the date and location of the accident, and the names and contact information of any other drivers or witnesses. Do not admit fault or apologize; straightforward state what happened. Take photos of vehicle damage, road conditions, and the accident scene if it is safe to do so.
Your insurer will assign a claims adjuster who will contact you to schedule an inspection of your vehicle. The adjuster will estimate repair costs and determine whether the damage is covered under your policy. If the damage is covered, the insurer will either authorize repairs at a shop of your choice or pay you directly to repair it yourself.
If the other driver is at fault and their insurer is paying, the process is similar but slower — their adjuster must also inspect the vehicle and approve the estimate. This can take two to four weeks. If liability is disputed, the insurers may hire independent appraisers or send the case to mediation. Most disputes are resolved within 30 to 60 days.
Frequently Asked Questions
Can I get insurance if I have a suspended license?
Yes. Insurers can sell you a policy even if your license is suspended, though you cannot legally drive. If you are restoring your license after suspension for driving uninsured, you will need an SR-22 form from your insurer before the DMV will reinstate you. Some insurers specialize in high-risk drivers and suspended licenses.
What is the difference between actual cash value and agreed value?
Actual cash value is what your car is worth on the used market at the time of loss, minus depreciation. Agreed value is a set amount you and your insurer agree on beforehand, usually for older or classic cars. Agreed value protects you if your car is totaled, because you receive the agreed amount regardless of market conditions.
Do I need insurance if I only drive occasionally?
Yes. California law requires insurance for any vehicle registered in your name, even if you drive it rarely. If you are hit while driving without insurance — even if the accident is not your fault — you cannot recover damages from the other driver's insurer. The only exception is if your car is stored and not driven; you can request a non-operation status from the DMV.
What happens if I let my insurance lapse?
If your coverage lapses for even one day, the DMV is notified and your registration is suspended. You cannot legally drive until you reinstate coverage and file an SR-22 form. If you are caught driving with a lapsed policy, you face fines and possible license suspension. Reinstating coverage is usually faster than the original purchase, but you may pay a higher rate as a high-risk driver.
Can my insurer raise my rate after an accident that was not my fault?
California law prohibits insurers from raising your rate based solely on an accident you did not cause. However, if the accident results in a claim that costs the insurer money, they may raise your rate at renewal. Some insurers offer accident forgiveness programs that prevent a rate increase for your first accident. Ask your insurer whether they offer this option.
