California is an at-fault (tort) state. Drivers must carry at least 30/60/15 in coverage, and the average full-coverage premium is $3,001 a year, 3% above the national average of $2,922. This guide covers what California requires, what drivers pay, the rules on fault, uninsured drivers, penalties, teen drivers and phone use, and how to pay less.
| Minimum coverage | 30/60/15 |
| Fault system | At-fault (tort) |
| Average full coverage | $3,001 a year ($250 a month), 3% above the national average of $2,922 |
| Uninsured drivers | 20.4% (2023), the 8th highest rate of 51 |
| Filing after serious violations | SR-22 |
California requires $30,000 for injury or death to one person, $60,000 for injury or death to more than one person, and $15,000 for property damage (California DMV, "Auto Insurance Requirements"; limits in effect since January 1, 2025).
Instead of an insurance policy, California accepts a $75,000 cash deposit with the DMV, a $75,000 surety bond from a California-licensed company, or a DMV-issued self-insurance certificate.
The minimums are a legal floor, not a recommendation. Property damage limits in particular don't go far when a new car can cost more than the limit to replace, and anything above your limits is your personal responsibility. See how limits and deductibles work and every type of coverage explained.
The average full-coverage premium in California is $3,001 a year, 3% above the national average of $2,922. That makes California the 14th most expensive of 49 (48 states plus D.C.; Alaska and Hawaii aren't in the data) (Experian, "Car Insurance Average Costs by State," published September 9, 2026; full coverage, 12 months to August 2026).
Premiums vary sharply across the state. Dense urban areas typically cost far more than rural counties, and California insurers have to justify rate changes to the Department of Insurance under Proposition 103.

California uses pure comparative negligence: you can recover damages reduced by your percentage of fault, even if you were mostly to blame (Li v. Yellow Cab Co., California Supreme Court, 1975).
An estimated 20.4% of California drivers were uninsured in 2023, the 8th highest rate among the 50 states and D.C. (Insurance Research Council, uninsured motorist estimates for 2023, via Insurance Information Institute "Facts + Statistics: Uninsured motorists"). Uninsured and underinsured motorist coverage protects you when one of them hits you. See coverage types.
Insurers report coverage to the DMV electronically. If the DMV doesn't receive proof of insurance for a vehicle, its registration is suspended and it can't be driven or parked on public roads until proof is submitted. Tell the DMV before canceling coverage, for example if you sell the car or store it. (California DMV, "Auto Insurance Requirements")
Driving without insurance is an infraction: a fine of $100 to $200 plus penalty assessments for a first offense, and $200 to $500 plus penalty assessments for another offense within three years. The court may also order the vehicle impounded. If you are in a collision without insurance, your driving privilege can be suspended for up to four years, whoever was at fault. (California Vehicle Code §16029; California DMV, California Driver Handbook, Section 10)
A conviction for driving uninsured also follows you into your next policy. In CarInsurance.com's rate analysis, it raised the average full-coverage premium in California from $2,416 to $3,652 a year, an increase of 51% (CarInsurance.com, "Penalty for driving without insurance in every state," updated March 24, 2026; rate analysis).
Beyond the penalties, driving uninsured leaves you personally liable for any damage you cause. See what happens if you drive without car insurance.
After a collision without insurance, you can regain your license during the last three years of the suspension by filing and keeping an SR-22 (California Insurance Proof Certificate). You must also report any collision to the DMV on form SR-1 within 10 days if it caused more than $1,000 of damage or any injury, whoever was at fault.
Under Proposition 103, the three most important factors in a California auto premium must be, in this order, your driving safety record, the miles you drive each year, and your years of driving experience. California also doesn't allow insurers to use gender or credit-based insurance scores to set auto rates. (California Department of Insurance; AgentSync (2026); Experian (2026))
California uses graduated driver licensing (Insurance Institute for Highway Safety, "Graduated licensing laws" table):
Adding a teen is usually the biggest single increase in a family's premium. Keeping them on the family policy, a good-student discount and a safe, modest car help most.
A distracted-driving ticket can count against your record and your premium. (Insurance Institute for Highway Safety, "Electronic device laws" table)
California Low Cost Automobile Insurance Program (CLCA). Low-priced liability cover for drivers with a good record and a household income up to 250% of the federal poverty guideline. Apply at mylowcostauto.com or call 1-866-602-8861. (California Department of Insurance; California DMV)
