Why Did Car Insurance Go Up in California?
The Short Version
- California auto rates climbed hard from 2023 through 2025 after a long pause on rate changes during the pandemic, and carriers filed to catch up all at once.
- Repair costs, medical and injury claim costs, and higher state minimum liability limits all pushed premiums up at the same time.
- The pace of increases has slowed. The state's largest auto insurer received approval for a rate reduction in 2026, and carriers that had pulled back are competing for business again.
- Slower does not mean frozen. Your own renewal can still change based on your vehicle, your record, and where you park at night.
- Because rate filings vary by carrier, the same driver can get very different prices on the same day. That is where an independent agent earns their keep.
If you opened your renewal notice over the past couple of years and felt your stomach drop, you were not imagining things and you were not alone. California drivers absorbed some of the steepest auto insurance increases in decades between 2023 and 2025. The good news, and it is real good news, is that the worst of that wave has largely worked its way through the system.
Here is what actually happened, why it hit all at once, and where things stand now for drivers in the Antelope Valley and downtown Los Angeles.
Why did car insurance go up in California?
Insurance pricing in California does not move the way pricing moves in most states. Under Proposition 103, passed by voters in 1988, an insurance company cannot simply raise your rate when its costs go up. It has to file a request with the California Department of Insurance and wait for approval. That system protects consumers from sudden pricing swings, but it also means adjustments arrive in large, delayed batches rather than small, steady steps.
During the pandemic, driving dropped, claims dropped, and rate changes in California were effectively put on hold. Meanwhile, the underlying costs of fixing cars and treating injuries kept climbing. When filings started moving again, carriers were not asking for one year of catch up. They were asking for several. That is the single biggest reason the increases felt so abrupt.
The 5 reasons California car insurance rates increased
1. The backlog of delayed rate filings
This is the mechanical cause. Years of cost increases were approved in a compressed window, so drivers experienced several years of change across one or two renewals. If your premium jumped in a way that felt disproportionate to anything you did, this is usually the explanation.
2. Vehicles cost far more to repair
A modern bumper is not a bumper. It houses parking sensors, cameras, and radar modules tied to driver assistance systems. A minor parking lot tap that once meant a paint job can now mean sensor replacement plus recalibration. Add higher parts prices, longer supply timelines, and higher labor rates, and the average physical damage claim costs meaningfully more than it did five years ago.
3. Injury and medical claim costs kept climbing
Bodily injury claims have grown more expensive across the board, driven by medical cost inflation, longer claim resolution timelines, and more frequent litigation. Industry research through 2025 showed California injury claim costs rising faster than the national average, and those costs are the actuarial basis carriers point to when they file for increases.
4. New state minimum liability limits
On January 1, 2025, California raised its minimum required liability coverage for the first time since 1967. Every policy issued or renewed after that date carries more coverage than before, and more coverage costs more. Drivers who had been sitting on the old bare minimum felt this the most.
5. Fewer carriers competing for your business
When carriers lose money in a state, they stop writing new policies, tighten who they will accept, or leave entirely. Several did exactly that in California. Less competition means fewer places to land when your rate goes up, which is why shopping felt so unproductive for a stretch.
Why did my car insurance go up if nothing happened?
This is the question we field most often, and the answer frustrates people because it feels impersonal. It is. When a carrier gets approval for a rate revision, that revision flows to policies as they renew. A clean record does not exempt you. It just means you are paying a better price than you otherwise would within the new structure.
A few other things can move your premium without any action on your part:
- Your vehicle got a year older, and repair cost data for that model was updated.
- Claim activity in your ZIP code changed, including theft and vandalism trends.
- A discount quietly aged off, such as a multi policy or student discount tied to a status that changed.
- Your policy renewed into the higher state minimum limits.
- A violation from years back finally dropped off, which lowers your rate, or a newer one landed, which raises it.
One thing that is not moving your California auto premium: your credit score. California is one of a small number of states that prohibits insurers from using credit history to rate personal auto insurance. Under Proposition 103, the three mandatory rating factors carriers must weigh most heavily are your driving safety record, your annual miles driven, and your years of driving experience.
Are California car insurance rates still going up?
Here is the honest picture, without spin in either direction.
The double digit increases that defined 2023 and 2024 are not what carriers are filing now. Claim frequency and physical damage severity eased enough that at least one major carrier reversed course entirely, filing for and receiving approval on a personal auto rate reduction that took effect in California in 2026. Carriers that had paused new business are writing again, and competition among them has picked up noticeably from the agency side of the desk.
What has changed, and what has not
- Slowed: The pace of approved rate increases has moderated substantially from the 2023 and 2024 peak.
- Improved: Availability. More carriers are accepting new business, which gives you more options when you shop.
- Reversed, in some cases: A handful of carriers have filed rate decreases rather than increases.
- Still rising: Injury and medical claim costs, which is why some carriers are still filing for increases.
- Still true: Your individual renewal depends on your vehicle, record, mileage, and location, not on a statewide average.
So if you are asking whether you should expect your next renewal to be lower, the fair answer is that it might be, and it is far more likely to be flat or modestly changed than it was two years ago. What has genuinely changed is that shopping is worth your time again, because there are real differences between carriers and real appetite for new business.
What is the new car insurance law in California?
Signed in 2022 and effective at the start of 2025, SB 1107 applies to any policy issued or renewed in California on or after that date. If you were carrying the old minimum, your policy was moved up automatically at renewal.
| Coverage | Old minimum (through 2024) | Current minimum (2025 forward) |
|---|---|---|
| Bodily injury, one person | $15,000 | $30,000 |
| Bodily injury, all persons per accident | $30,000 | $60,000 |
| Property damage per accident | $5,000 | $15,000 |
Worth knowing: the same law schedules another step up to 50/100/25 on January 1, 2035. That is a long way off, but it tells you the direction of travel.
It is also worth saying plainly that the higher limits are not a bad thing for you. At $5,000 of property damage coverage, a single collision with a late model SUV could leave you personally on the hook for the difference. The new floor is closer to reality, even though it costs more.
Who has the cheapest auto insurance in California?
We understand why people want a name. It would make this simple. But it would also be misleading, and here is the concrete reason why.
Each carrier files its own rating plan with the Department of Insurance, and those plans differ in how they treat almost everything: the age of your vehicle, a gap in prior coverage, an SR-22 filing, a teen driver on the policy, whether you rent or own. Two drivers on the same street with the same record can get their best price from two completely different companies. A carrier that is aggressive on clean record commuters may be uncompetitive on a driver rebuilding after a lapse.
That is the actual answer to the cheapest question: cheapest is a function of your profile, not a fixed ranking. What we do at Express Lane Insurance is run your profile across the carriers we represent and show you where you land, rather than sending you to fill out the same form eight times.
How can I lower my car insurance in California?
Compare carriers at every renewal
Rate filings change constantly, and the carrier that was best for you two years ago may not be now. This is the single biggest lever, and it costs you nothing but a conversation.
Right size your deductibles
Raising a collision or comprehensive deductible lowers your premium, but only choose an amount you could actually write a check for tomorrow. A low premium that you cannot afford to use is not a savings.
Report your real annual mileage
Mileage is a mandatory rating factor in California. If you changed jobs, started working from home, or retired, your rate should reflect the miles you actually drive.
Bundle what you can
Pairing auto with home, renters, or another policy often produces a meaningful multi policy discount on both.
Audit your discounts
Good driver, mature driver course completion, good student, paid in full, paperless, and vehicle safety features are all commonly missed. Ask us to review the list against your policy.
Do not solve it by dropping coverage
Cutting back to bare minimums lowers the bill and raises your personal exposure. If cost is the pressure, there are usually better levers to pull first.
What this means for Antelope Valley and Los Angeles drivers
Location is a real factor in your premium, and it works at the ZIP code level, not the city level. Drivers in Lancaster, Palmdale, and Quartz Hill often see different pricing than drivers a short distance away, and downtown Los Angeles carries its own claim and theft profile entirely.
What that means practically: if you commute from the Antelope Valley into the Los Angeles basin, your mileage, your parking situation at both ends, and your ZIP code all interact in ways that different carriers price very differently. That is a scenario where shopping across multiple companies tends to produce the widest spread in quotes, and the biggest opportunity to save.

Frequently asked questions
Why did my car insurance go up if nothing happened?
When a carrier receives approval for a rate change from the California Department of Insurance, that change applies to every policy in the affected rating group at renewal, not just to drivers with claims or violations. Your premium can rise with a perfect record. Other quiet causes include your vehicle aging into different repair cost data, changes in claim activity in your ZIP code, a discount aging off, or your policy renewing into the higher state minimum liability limits.
Are California car insurance rates still going up?
The pace of increases has slowed considerably. The sharp jumps of 2023 through 2025 have largely worked through the system, and in 2026 the state's largest auto insurer received approval for a personal auto rate reduction. Injury and medical claim costs are still rising, so some carriers continue to file for increases. Your individual renewal depends on your vehicle, driving record, mileage, and location rather than on any statewide average.
What is the new car insurance law in California?
Senate Bill 1107, known as the Protect California Drivers Act, took effect January 1, 2025. It raised the state's minimum liability limits from 15/30/5 to 30/60/15, meaning $30,000 for bodily injury or death of one person, $60,000 for all persons in one accident, and $15,000 for property damage. It was the first increase since 1967, and the same law schedules a further increase to 50/100/25 on January 1, 2035.
Does California use credit scores to set auto insurance rates?
No. California prohibits insurers from using credit history to rate personal auto insurance. Under Proposition 103, the mandatory rating factors carriers must weigh most heavily are your driving safety record, your annual miles driven, and your years of driving experience.
Who has the cheapest auto insurance in California?
There is no single cheapest carrier. Each company files its own rating plan with the California Department of Insurance, and those plans treat vehicles, driving records, mileage, coverage gaps, and ZIP codes very differently. The cheapest option for one driver can be among the most expensive for another driver on the same street. Comparing multiple carriers against your own profile is the only reliable way to find your lowest price.
How can I lower my car insurance in California?
Compare multiple carriers at every renewal, since rate filings change constantly. Adjust your deductibles to an amount you could realistically pay out of pocket, report your accurate annual mileage, bundle auto with home or renters coverage, and confirm that every discount you qualify for is actually applied. Dropping coverage down to bare minimums lowers the bill but raises your personal financial exposure, so treat that as a last resort.
