Once a year, your car insurance deserves an hour of your attention. The NAIC itself suggests checking your policies annually to make sure the coverage still fits your life and you’re still getting a good deal. Year-end is the natural moment: renewals cluster, life changes accumulate, and a systematic review can surface hundreds of dollars in savings — or coverage gaps you didn’t know you had.
Why an annual review matters
Car insurance is priced on a snapshot of you — your car, your address, your mileage, your driving record, your credit-based insurance score where allowed. Every one of those inputs drifts over a year, and the drift usually costs you money in one of two directions: you’re either overpaying for coverage that no longer fits, or underinsured for risks that have grown.
The market has also been unusually volatile. With 57% of drivers shopping for coverage in 2025 — the highest level J.D. Power has recorded — the price you accepted at your last renewal may not be competitive anymore (J.D. Power 2026 Outlook via InsuranceNewsNet). An annual review is how you capture the benefit of that competition instead of subsidizing it.
Set aside an hour, pull up your declarations page (the summary showing your coverages, limits, deductibles, and premiums), and work through the four parts below.
Part 1 — Coverage: limits, deductibles, and fit
Liability limits. Your state’s minimum is a legal floor, not a recommendation — and minimums haven’t kept pace with the cost of crashes. The Triple-I reports the 2024 average bodily injury liability claim at $28,278 and the average property damage claim at $6,770, while a serious multi-vehicle crash can run into six figures (Triple-I). If your limits are still at the state minimum from years ago, price the next step up (commonly 100/300/100). The incremental cost is often smaller than drivers expect. Our state minimum guide and full coverage vs liability explain the trade-offs.
Collision and comprehensive. About 80% of insured drivers buy comprehensive and 77% buy collision, per Triple-I analysis of NAIC data (Triple-I) — but that doesn’t mean you should. The rule of thumb: if your car’s market value has fallen to the point where a total-loss payout (value minus deductible) wouldn’t meaningfully help you, consider dropping one or both. Re-run this math every year as the car depreciates.
Deductibles. Higher deductibles lower premiums. If your emergency fund has grown, raising your deductible from $500 to $1,000 is often one of the cheapest ways to cut your premium — but only if you could actually pay the higher amount tomorrow. Be honest about that.
Optional coverages. Rental reimbursement, towing/roadside, and (if financed) gap coverage: check whether you still need each one. Paid off the loan this year? Gap insurance can be canceled, and the CFPB confirms you have the right to cancel optional add-ons at any time (CFPB). Got AAA or another auto club? You may be double-paying for roadside.
Part 2 — Discounts: the audit
Carriers don’t always apply every discount you qualify for — many require you to ask. Run down this list against your declarations page:
- Multi-policy / bundling. Insuring home (or renters) and auto with one carrier typically saves 10–25%. If you bought a home or moved to a rental this year, this discount may be newly available — see our honest bundling math.
- Mileage. Driving less than you used to — remote work, retirement, a shorter commute — can qualify you for low-mileage discounts or make usage-based insurance attractive. 17% of insurers offered usage-based programs in 2025.
- Defensive driving course. Many states and carriers offer discounts for completing an approved course — worth checking if your record has a blemish aging off.
- Good student. If you added a teen driver this year, the good-student discount is one of the biggest available offsets to the teen-driver surcharge. See car insurance for teens.
- Safety features. If you bought a newer car, make sure the carrier knows about its airbags, anti-theft system, and driver-assistance features. Our guide to safety feature discounts covers which ones actually move the needle and how to document them.
- Payment discounts. Pay-in-full and paperless/autopay discounts are small individually but stack with everything else.
- Affinity and occupation. Alumni associations, professional groups, and some employers have group discount programs — easy to overlook.
The NAIC’s quote-comparison guidance adds a useful discipline here: when you check discounts, also verify that all drivers in your household are correctly listed, since an unlisted driver involved in a crash can cause coverage problems (NAIC).
Part 3 — Life changes to report
Insurers price on your current reality. These are the changes that most commonly go unreported — and they cut both ways:
| Life change | Likely effect on premium |
|---|---|
| Moved to a new ZIP code | Varies widely — urban vs rural, theft rates, weather |
| Married (or divorced) | Married drivers often pay less; update either way |
| Added a teen driver | Usually increases — ask about good-student and training discounts |
| New car (especially new/EV) | Usually increases — higher value, costlier repairs |
| Paid off the car loan | May allow dropping collision/comprehensive or gap |
| Retired / working from home | Lower mileage — ask about mileage-based discounts |
| Credit score improved (where allowed) | Can lower premiums in most states |
Also update garaging address, annual mileage estimates, and how the car is used (commute vs pleasure). Inaccurate information on the application can cause problems at claim time — the NAIC stresses complete disclosure as a matter of mutual trust between you and your insurer (NAIC).
Part 4 — Shopping cadence: stay or switch
Year-end is also the moment to decide whether your carrier still deserves your business:
- Get 3–5 competing quotes with coverage identical to your current policy — same limits, same deductibles, same endorsements. The NAIC emphasizes that quotes without matching coverages can’t be meaningfully compared (NAIC).
- Compare the total, then call your current insurer. Give them a chance to match or explain. Sometimes a retention offer appears; sometimes the explanation reveals you’re already well-priced.
- Check complaint records. Before switching to an unfamiliar carrier, look up its complaint ratio with your state insurance department — the NAIC recommends this as standard homework (NAIC).
- Switch without a gap. Keep the old policy active until the new one is confirmed in force, and confirm any refund of unused premium. Our switching guide covers cancellation fees, timing, and proof-of-insurance continuity.
Remember that 2025’s record shopping translated into record switching (29% changed insurers) — carriers are competing for your business right now, which is precisely when shopping pays off (J.D. Power 2026 Outlook via InsuranceNewsNet). Our fall 2026 rate outlook breaks down which pressures are still building and which are easing.
Your year-end action list
- [ ] Pull your declarations page and read it — limits, deductibles, listed drivers, discounts applied
- [ ] Price higher liability limits if you’re still at state minimums
- [ ] Re-run the collision/comprehensive math against your car’s current value
- [ ] Confirm your deductible still matches your emergency fund
- [ ] Audit every discount on the list above — call and ask for missing ones
- [ ] Report life changes: moves, drivers, mileage, marital status, paid-off loans
- [ ] Cancel coverage you no longer need (gap after payoff, duplicate roadside)
- [ ] Get 3–5 matching-coverage quotes and decide: stay or switch
- Review annually: coverage fit, deductibles, discounts, and life changes — the NAIC recommends a yearly check.
- Re-price liability limits upward from state minimums and re-test collision/comprehensive as your car depreciates.
- Audit discounts actively; bundling, mileage, safety features, and payment discounts are the most commonly missed.
- Shop with identical coverages before every renewal — record shopping levels mean carriers are competing for switchers.
Frequently asked questions
How often should I shop for car insurance?
At least once a year, at renewal. More often if something material changes — a move, a new car, a new driver, or a paid-off loan. Shopping takes an hour; the savings can persist for the whole policy term.
Will shopping around hurt my credit?
Insurance quotes may involve a soft inquiry or a credit-based insurance score check, which doesn’t affect your credit score the way a hard inquiry for a loan does. Comparing quotes is safe.
Should I switch mid-policy or wait for renewal?
Either works, but renewal is simplest. Mid-policy switches are allowed — you’ll get a refund of unused premium — but watch for short-rate cancellation fees and make sure the new policy is active before canceling the old one. See switching car insurance for the details.
What if my renewal offer looks much higher than last year?
Don’t auto-renew a big increase. First check whether anything on your end changed — a claim, a ticket, a move, or a vehicle change. If nothing changed, the increase is likely the carrier repricing its book, and that’s your signal to shop. Get three comparable quotes before your renewal date; loyalty rarely beats a fresh market check.
What documents do I need for the review?
Your declarations page (current coverages and premiums), your renewal offer, driver’s license numbers for all household drivers, vehicle registration details, and any records of life changes (new address, new car purchase, course completions). The NAIC’s quote-comparison guide lists exactly what to have ready (NAIC).
