The fastest way to lower your auto insurance costs in California is to compare quotes from several carriers, make sure you're getting every discount you qualify for (especially the Good Driver Discount), and update your policy with accurate mileage and vehicle details. Small changes like raising a deductible or bundling your policies can add up too. The start of a new year is a natural time to do all of it at once.
At Thrifty Insurance Services, we see it every January: drivers who renewed on autopilot for years and never asked whether a better rate was sitting with another carrier. Here's what actually moves the needle on your premium, and what to leave alone.
What Drives Auto Insurance Costs in California?
California does things differently from most states. Under Proposition 103, insurers must base auto rates primarily on three factors, in this order of importance, according to California Insurance Code Section 1861.02:
- Your driving safety record
- The number of miles you drive each year
- Your years of driving experience
Other factors can still play a role, but these three carry the most weight. The same law also says that not having prior insurance, by itself, can't be used to decide your eligibility for a Good Driver Discount or your rates. That's good news if you're coming back to driving after a break.
8 Ways to Lower Your Auto Insurance Costs This Year
Compare Quotes Across Multiple Carriers
Rates for the same driver can vary widely from one company to the next. As an independent agency, Thrifty works with more than a dozen carriers, including Progressive, Mercury, Travelers, Kemper, and Geico, so we can compare options side by side for you instead of you calling each one. As our team likes to say: We Search. We Find. You Save.
Protect Your Good Driver Discount
If you qualify as a good driver in California, the law requires your rate to be at least 20% below what you'd otherwise pay for the same coverage (Cal. Ins. Code § 1861.02). A single at-fault accident or moving violation can put that discount at risk, so a clean year behind the wheel pays off at renewal.
Update Your Annual Mileage
Since mileage is one of the three main rating factors, an outdated estimate can cost you. Did you start working from home, switch to a closer job, or retire last year? Tell your agent. Fewer miles driven can mean a lower premium.
Raise Your Deductible (If Your Savings Can Handle It)
A higher collision and comprehensive deductible typically lowers your premium. Just pick an amount you could comfortably pay out of pocket after a claim.
Bundle Auto with Home or Renters Insurance
Many carriers offer a discount when you combine auto with homeowners insurance or renters coverage under the same company. It also means one agent to call when something happens.
Put All Household Vehicles on One Policy
Multi-vehicle discounts are common. If family members are insured separately, it's worth checking whether combining them saves money.
Take a Mature Driver Course (Age 55+)
According to the California Department of Insurance, drivers 55 and older who complete a DMV-approved mature driver improvement course can get lower premiums from most auto insurers for up to three years, and can usually keep the discount by retaking the course every three years.
Right-Size Coverage on Older Vehicles
If your car is paid off and worth relatively little, full collision and comprehensive coverage may cost more than it's worth over time. Talk it through before dropping anything, though. If you have a loan or lease, your lender will likely require these coverages.
Don't Cut Your Liability Coverage Too Far
Lowering your premium shouldn't mean leaving yourself exposed. Since January 1, 2025, California's minimum liability limits are $30,000 per person for bodily injury, $60,000 per accident for bodily injury, and $15,000 for property damage, as listed by the California DMV. Under SB 1107, those minimums are scheduled to rise again in 2035.
State minimums may not fully protect you after a major accident, especially one involving several people or a newer vehicle. And letting your policy lapse to save a month's premium can backfire at your next renewal. If money is tight, call us first. There are usually affordable options available.
Is There a Low-Cost Option for Income-Qualified Drivers?
Yes. The state's California Low Cost Automobile Insurance Program (CLCA) offers basic liability coverage to drivers who meet income limits (up to 250% of the federal poverty level), own a vehicle valued at $25,000 or less, are at least 16, hold a valid California license, and have a good driving record. Coverage limits are lower than a standard policy, so it's best suited to drivers who need an affordable way to stay legal on the road.
