How Much Does Insurance Go Up After an Accident?
No honest average exists. What California law defines instead is exactly what is at stake.
Every site quoting you an average increase is inventing it. California is the one state where the rating rules are written into statute — so here is what an accident can actually change, what it cannot touch, and the number the law itself puts on the line.
The short answer
No one can tell you the increase in advance — every company files its own rating plan. What California law defines is the stake: a Good Driver Discount policy must be priced at least 20% below what you would otherwise pay, and Insurance Code section 1861.025 spells out which accidents can cost you that status. A principally-at-fault accident with property damage only counts as one point — survivable if it is your only one. One with bodily injury or death disqualifies you. And the lookback is three years, after which the accident ages off. The renewal after an accident is the single best moment to compare companies, because they price the same record very differently.
An accident and your rate, at a glance
Eight facts, starting with the honest one: nobody can quote your increase in advance. What the law defines instead is which accidents count, and exactly what they put at stake.
- Nobody can tell you in advance how much an accident raises YOUR rate — including us. Every company files its own rating plan, and the honest version of this page starts there.
- What California law does define is the stake. Under Insurance Code section 1861.02, a Good Driver Discount policy must be priced at least 20 percent below what the same driver would otherwise pay — so losing good-driver status has a statutory floor on what it costs.
- Proposition 103 fixes the order of what matters: your driving safety record first, then annual miles, then years licensed. An accident lands on the factor the law weighs heaviest.
- Good-driver status (Insurance Code section 1861.025) requires being licensed the previous three years with not more than one violation point.
- A principally-at-fault accident that caused only property damage counts as one violation point under that section. If it is your only point, you can still qualify as a good driver — a second point ends it.
- A principally-at-fault accident that resulted in bodily injury or death is disqualifying on its own.
- "Principally at fault" is a determination your insurer makes — an accident is not automatically chargeable just because it happened. If you dispute it, ask the company for the basis of the determination.
- The three-year lookback means an accident ages off. The renewal after it falls outside the window is the one where the price should move back — and the one worth re-shopping if it does not.
What the law sorts, sorted the same way
California is unusual: Proposition 103 wrote the rating rules into statute. That splits everything about an accident into three piles — what can move your rate, what the law shields, and what only your company can answer.
A principally-at-fault accident, property damage only
One violation point under Insurance Code section 1861.025. Survivable if it is your only point — the statute allows not more than one — but it uses up the whole allowance.
A principally-at-fault accident with injury or death
Disqualifying for good-driver status on its own under section 1861.025. This is the category where the statutory 20% floor is lost outright.
A ticket stacked on top of the accident
The second point is what ends good-driver status when the accident was the first. The year after an accident is the year traffic school earns its keep.
An accident where you were NOT principally at fault
Not countable toward the good-driver point limit — section 1861.025 counts principally-at-fault accidents. If your renewal jumped anyway, ask how the accident was coded.
Anything past the three-year lookback
Good-driver qualification looks at the previous three years. The accident ages off — put the date in your calendar, because the first renewal past it is the scheduled re-shop.
The order of what matters most
Section 1861.02 fixes it: driving safety record first, then miles driven, then years licensed. A clean record going forward is the factor with the most statutory weight.
How much your specific rate moves
Each company files its own plan, and they genuinely differ on the same record. No average is honest — the renewal quote and a market comparison are the only real numbers.
Accident forgiveness, and what it covers
A product some companies offer and others do not, on terms in the policy contract rather than in California law. If you are counting on it, read yours before the renewal, not after.
The 20% the statute puts on the table
Most states leave accident surcharges entirely to the market. California wrote a number into law: a qualifying good driver must be offered a policy at least 20 percent below the rate they would otherwise pay for the same coverage. That makes the real question after an accident precise — did this cost me good-driver status? — because that status carries a discount with a statutory floor, not a marketing one.
One point is survivable. Two is not.
A property-damage-only at-fault accident is one point, and the statute allows not more than one. What actually ends good-driver status for most people is the second point — the ordinary ticket in the year after the accident. Drive like the allowance is spent, because it is.
What is not the same at every company
California law sets the floor. Everything below it is written into individual policies and differs between companies, so the honest answer is where to find your answer — not an average.
- How much an at-fault accident moves your specific renewal
- The renewal offer itself, and a market comparison against it. Rating plans are filed per company; two insurers can price the same accident very differently, and that spread is the whole reason to compare at this exact moment.
- How the company weighs a not-chargeable accident inside its filed plan
- Ask directly: was this accident recorded as principally at fault, and is it affecting my premium? The coding, not the crash, is what your price is built on.
- Whether accident forgiveness exists on your policy and what it forgives
- Your policy contract and declarations. It is a company product, not a California rule — and its fine print (first accident only? which coverages?) is the part that matters.
- What happens to a claim you wanted to pay privately
- Your policy’s claim-reporting conditions. When another party is involved, their claim can surface months later, so the reporting decision is about your contract terms, not just this month’s rate.
The renewal after an accident is the one to shop
From our office, the pattern is consistent: companies diverge more on a record with an accident on it than on a clean one. The renewal in your hand is one company’s answer to your new record. Somebody else’s filed plan often answers differently — and after three clean years, the calculation resets again.
Bring us the renewal, not a guess
With the actual offer in hand we can compare it against every company we write in minutes, tell you whether the accident was coded chargeable, and put the three-year date in the file so the re-shop happens on schedule instead of never.

Where this comes from
Both statutes were checked against the official text before this page was written, and they are linked so you can check us. What we deliberately did not print: any average increase — no honest one exists — and the regulatory fault-determination thresholds, which we could not verify against a primary source at the time of writing.
- California Insurance Code section 1861.02
Sets the mandatory rating factors in decreasing order of importance — driving safety record, annual miles, years of driving experience — and requires that a Good Driver Discount policy be priced at least 20 percent below the rate the insured would otherwise have been charged for the same coverage.
- California Insurance Code section 1861.025
Defines who qualifies as a good driver: licensed for the previous three years, with not more than one violation point — and specifies that a principally-at-fault accident causing only property damage counts as one point, while a principally-at-fault accident resulting in bodily injury or death is disqualifying.
