How annual mileage and car use affect car insurance

Why mileage affects car insurance

Every mile you drive is exposure to risk. Two drivers with identical records, cars and addresses do not have the same chance of a claim if one drives twice as far. That is why the NAIC lists annual mileage among the common factors insurers use, and why some states give it extra weight.

In California, the law goes further. It requires insurers to make driving safety record, annual miles driven and years of driving experience the three factors with the most weight, in that order. So in California, mileage must count more than where you live or what you drive.

How much does the average American drive?

The Federal Highway Administration (FHWA) publishes national travel data each year in its Highway Statistics series. For 2024:

These are averages per vehicle, not per driver. A household with two cars and one long commute may put most of its miles on one car. Insurers usually ask about each car separately.

What counts as low mileage?

There is no legal definition. Each insurer sets its own mileage bands, and some offer a discount below a certain yearly total. As a rough guide, a car driven well below the FHWA average is a lower-mileage car by national standards. Ask your insurer what bands it uses.

Commute, pleasure and business use

Insurers often ask how a car is used, not just how far it goes. California regulations list "type of use" as an optional rating factor, with examples such as pleasure only, commute, business and farm.

If you drive for a rideshare or delivery app, a standard personal policy may not cover you while the app is on. See rideshare insurance.

How insurers find out your mileage

1. Your estimate. Most insurers ask how many miles you expect to drive in the next year. In California, insurers use your estimate of the miles you will drive in the year after the policy starts, and may ask for supporting information.
2. Odometer readings. Insurers may use readings from inspections, repair shops, service records or vehicle history reports. California allows odometer readings from state agencies.
3. Photos or self-reports. Some insurers ask you to send odometer photos at renewal.
4. Devices and apps. Telematics devices, phone apps or connected-car data can record actual miles. See telematics.

Give an honest estimate. If your mileage turns out much higher than you reported, your insurer may adjust the premium at renewal. Misstating mileage on purpose can lead to problems with a claim.

California's rules on verified mileage

California lets insurers offer pricing based on verified actual mileage, including with a technological device. The regulations say:

• the device may be used only to collect information about miles driven
• the insurer may not use it to collect or store the location of the car, except for emergency road, theft, map or travel services
• participation must be voluntary
• the policyholder must be told about premium adjustments based on actual miles before the policy takes effect

Other states have their own rules. Ask your insurer what data a mileage program collects.

Low-mileage car insurance options

If you drive less than most people, you have several options:

1. Update your mileage estimate. If you changed jobs, started working from home or retired, tell your insurer. A lower mileage band can lower the price at renewal.
2. Change the use category. If you no longer commute, ask to have the car rated for pleasure use.
3. Ask about a low-mileage discount. Some insurers offer one below a set number of miles.
4. Look at pay-per-mile insurance. Distance-based policies, sometimes called pay-as-you-drive, charge a base rate plus a per-mile rate. The NAIC lists pay-as-you-drive and distance-based insurance among usage-based insurance types.
5. Try a telematics program. Some measure how you drive as well as how far. Results depend on the program.
6. Review coverage on a car you rarely drive. For a car in long-term storage, some insurers allow you to keep comprehensive only. Check your state's rules and your lender's requirements before dropping liability on a registered car.

Who might benefit from pay-per-mile?

Pay-per-mile tends to suit drivers who:

• work from home or live close to work
• use public transit, bike or walk for most trips
• are retired or drive mainly for errands
• have a second car that sits most of the week

It may cost more than a standard policy if you take long road trips or your driving increases. Compare the base rate and the per-mile rate against your real yearly miles. See also shopping at renewal and car insurance discounts.

How to compare pay-per-mile with a standard policy

A pay-per-mile bill has two parts: a fixed monthly base rate and a charge for each mile you drive. To compare it with a standard policy:

1. Track your real mileage for a month or two. Write down your odometer reading at the start and end, or use your car's trip meter.
2. Multiply your monthly miles by the quoted per-mile rate, then add the base rate. That is your estimated monthly bill.
3. Add the months with long trips. Some programs cap the miles charged per day, which limits the cost of a road trip. Ask whether yours does.
4. Compare a full year, not a single month, with the yearly price of a standard policy that has the same coverage, limits and deductibles.
5. Check what else is tracked. Some programs record only miles; others also score driving behavior.

Track your own mileage

Knowing your real mileage helps you answer insurer questions accurately and spot savings:

• Note your odometer reading on the same date each year, for example when you renew.
• Keep service records, which usually list the odometer reading.
• If your life changes (a new job, a move, retirement or a child leaving for college), recheck your mileage and tell your insurer.
• If a household car is rarely used, ask whether it can be rated for pleasure use or lower mileage.

Mileage is one of several car insurance cost factors. Your driving record, age and experience and ZIP code also shape the price.
