Car insurance pricing is built from risk estimates, so the biggest levers are the inputs that shift risk the most.
Insurers can only use factors allowed in your state, and those rules change what questions appear on a quote.
A quote is mostly two parts: your risk profile and the coverage choices that decide who pays what.
How insurers build the “base” price
Auto premiums reflect expected claim costs plus expenses, using signals tied to drivers, vehicles, and use.
Common rating factors include location, driving record, claims history, vehicle type, miles driven, and chosen coverages.
Small changes in a high-impact factor can move a rate more than many small changes in low-impact factors.
Your job is to find the few factors your insurer is weighting heavily and adjust what you can safely control.
Risk pricing in plain language
Insurers price both frequency risk and severity risk, meaning how often losses happen and how costly they are.
Inputs that raise crash odds or raise repair and medical bills usually raise premiums.
Inputs that show lower exposure or safer behavior can qualify you for lower prices and discounts.
Why state rules matter
The NAIC lists common auto rating factors, but states decide which ones may be used and how.
That is why the same driver can see different pricing patterns after a move or across state lines.
When you compare quotes, you are comparing both the insurer’s model and the state’s rules.
Levers you can change quickly
Policy settings like deductibles, limits, and optional coverages can usually be changed at renewal or midterm.
Usage details like mileage and business use can be updated when your driving pattern changes.
Shopping is also a lever, because prices can vary a lot by insurer for the same coverage.
Driver and household factors that move rates fast
Driving record is a major lever because it is a direct signal of crash risk.
Age and driving experience often matter because insurers price risk by driver group and years licensed.
Claims history can matter because frequent claims can signal higher expected costs.
Prior insurance coverage is often reviewed, and continuous coverage can be treated as a stability signal.
Driving record and violations
The Insurance Information Institute notes that better records generally mean lower premiums.
Tickets and at-fault crashes can raise rates because they predict higher future loss frequency.
The most reliable “rate lever” here is time plus clean driving, since records improve as incidents age out.
Who drives the car and how often
Insurers price the listed drivers, so adding a new driver can change the quote even without a new car.
Households with newly licensed drivers often pay more because experience is a common rating input.
Accurate driver listings matter because insurers can re-rate later if regular drivers were not disclosed.
Claims history and prior coverage
The NAIC includes claims history among the main rating factors for auto insurance.
Claims records can be reviewed through industry databases, so even small claims can follow you between companies.
Keeping coverage continuous and reserving claims for larger losses can help keep your profile stable.
Where you live, what you drive, and what you buy
Location is a major lever because local accident rates, theft rates, and cost levels differ.
Mileage and use are big levers because more time on the road increases exposure to accidents.
Vehicle type is a lever because repair cost, safety tech, and theft risk vary by model.
Coverage choices are levers because limits and deductibles change how much the insurer might pay.
Location and territory rating
Florida’s auto insurance toolkit describes territory factors like vehicle density, road conditions, and local repair and medical costs.
Changing where the car is garaged, even within the same metro area, can change premiums because the territory changes.
If you move, update your address promptly so rating matches the real garaging location and risk profile.
Mileage, use, and telematics
The III says more miles usually means more accident opportunity, so higher annual mileage often costs more.
Florida’s consumer guidance also notes that changes in miles driven or switching from personal to commercial use can change premiums.
If your insurer offers usage-based pricing, it may reward safer patterns, but it also depends on what data is collected.
Coverage limits, deductibles, and credit-based scores
The NAIC shopping tool notes that what you buy, including liability amounts, affects what you pay.
NAIC consumer guidance explains that higher deductibles generally lower premiums because you pay more out of pocket first.
The NAIC also explains that many states allow credit-based insurance scores, which are distinct from standard credit scores.
Discounts and program choices that can shift pricing
State consumer guides note that discounts may be available for items like multiple policies, multiple vehicles, safety devices, or low mileage.
Some discounts reduce price without changing coverage, while others require choices like telematics or bundling that may not fit everyone.
When you ask for quotes, request the same coverages and also ask which discounts were applied so you can compare fairly.
Putting the levers to work at renewal
To compare companies, keep limits and deductibles identical across quotes, and ask which rating inputs and discounts drove the price.
Prioritize the high-impact basics first, including clean driving, accurate garaging and mileage, and a deductible you can actually pay.
Once a year, confirm your driver list, maintain continuous coverage, and review whether credit-based insurance scoring is used in your state.

Conclusion
The biggest car insurance cost levers are the ones that change risk and exposure the most, like driving record, location, mileage, and the vehicle you insure.
The fastest controllable levers are usually coverage choices, deductibles, and discounts you qualify for without weakening protection.
The most reliable long-term lever is keeping a clean record and stable, accurate policy details so your profile stays predictable to insurers.
