American drivers told their auto insurers they cover 7,589 miles a year. Federal Highway Administration data puts the real figure at 13,456, a 44% gap that Insurify measured across 97 million quotes and that a Jalopnik analysis pushed back into headlines on May 31, 2026.
That 5,867-mile shortfall carries weight because insurers price partly on how far you drive, so an estimate far below your odometer can spark a rate increase at renewal or sink a claim. Five rural states understated their mileage by more than 56%, with Wyoming reporting a 73% gap.
U.S. drivers report 7,589 miles a year to insurers versus the 13,456 miles federal data says they actually drive, a 44% gap Insurify found across 97 million quotes. Wyoming leads at 73%, trailed by Missouri, New Mexico, Mississippi, and North Dakota, all above 56%. Mileage feeds your premium, so a low estimate saves a few dollars now and can cost far more when an insurer corrects it at renewal or after a claim.
- Drivers report 7,589 miles a year against 13,456 actual, a 44% national gap drawn from 97 million Insurify quotes.
- Wyoming posts the widest gap at 73% (6,969 reported, 25,779 driven).
- Nine of the 10 worst-underreporting states carry poverty rates above the 11.5% national average, per U.S. Census data.
- Driving under 5,000 miles saves roughly $264 a year compared with topping 15,000, Insurify found.
- Insurers confirm mileage through odometer photos, oil-change receipts, telematics apps, and DMV records.
What the Insurify Data Shows
Insurify's data science team compared self-reported mileage from its quote database against the FHWA's 2021 Highway Statistics, the latest federal release. Drivers nationwide shaved an average of 6,049 miles off their real annual total. Only one place reported more than it drove: Washington, D.C., where motorists logged nearly 16% above the federal estimate.
The pattern sharpens in the states that miss by the most. Across the 10 worst offenders, drivers cut almost 58% off their actual mileage, an average understatement of 10,573 miles per year. The five widest gaps all sit in rural states with long distances between jobs, doctors, and grocery stores.
| State | Reported (mi/yr) | Actual FHWA (mi/yr) | Underreported | vs. U.S. 44% gap |
|---|---|---|---|---|
| Wyoming | 6,969 | 25,779 | 73% (18,810 mi) | +29 pts |
| Missouri | 7,699 | 18,664 | 58.7% (10,965 mi) | +15 pts |
| New Mexico | 7,497 | 18,158 | 58.7% (10,661 mi) | +15 pts |
| Mississippi | 8,700 | 20,000+ | 56.7% (11,300+ mi) | +13 pts |
| North Dakota | 7,333 | 16,838 | 56.4% (9,505 mi) | +12 pts |

Why Rural Drivers Underreport the Most
Wyoming drives more than any other state, yet its drivers reported just 6,969 miles while federal data clocks them at 25,779, a yearly gap of 18,810 miles that equals roughly 2.5 years of their own estimates. Poverty does not explain it here, since Wyoming sits near the national 11.5% rate; geography does, because the 10th-largest state holds the second-lowest population density. Drivers comparing options on our Wyoming car insurance page routinely underestimate the long non-commute trips that vast distances demand.
Missouri drivers understated mileage by 58.7%, reporting 7,699 miles against an actual 18,664, while paying an average full-coverage premium of $1,879. The state's 12.3% poverty rate runs above the national figure, and a low estimate could trim a bill that already strains budgets. New Mexico matched that 58.7% gap (7,497 reported, 18,158 driven) even though its average full-coverage premium of $1,669 sits $210 lower; the state combines a 17.6% poverty rate with 24.1% of drivers carrying no insurance at all, which pushes costs onto everyone who pays.
Distance to basic services drives the Mississippi gap, where motorists log more than 20,000 miles but report only 8,700, a 56.7% understatement. More than half the state's doctors practice in four urban areas while 54% of residents live rurally, and many households sit in food deserts where the nearest supermarket lies 10-plus miles away. North Dakota breaks the poverty pattern as the lone top-10 state at the national average, yet its drivers still cut 56.4% off their mileage (7,333 reported, 16,838 driven).
Insurify stopped short of calling the gap deliberate fraud. Rising premiums prompted nearly 55% of drivers to cut costs in 2023, from dropping to liability-only coverage to raising deductibles, and half the worst-underreporting states spend a larger share of income on car insurance than the 2.6% national norm. Honest underestimation, the report concluded, explains most of the shortfall.
How Mileage Affects What You Pay
Every additional 2,000 to 3,000 miles adds about $3 to $5 to a monthly premium, according to Insurify. Stretched across a year, drivers who stay under 5,000 miles pay roughly $264 less than those who push past 15,000. Mileage ranks below your driving record, vehicle, and age in pricing weight, yet it compounds over time.
Genuinely low-mileage drivers can capture that discount legally rather than guessing low. Carriers cut rates 10% to 30% for drivers under the 7,500-mile threshold, with Nationwide offering a 20% reduction and Farmers delivering up to $597 a year in savings, MoneyGeek's 2026 analysis found. Our guide to the low-mileage car insurance discount breaks down which insurers reward fewer miles and how to qualify.
Pay-per-mile programs go further by charging a base rate of $29 to $50 a month plus 2 to 7 cents for each mile, then verifying every mile through a plug-in device or phone app. That precision cuts both ways: telematics ended the guesswork, but it also hands insurers exact data, a tension on display after GM's $12.75 million settlement over driving data sold to insurance brokers.
Is Underreporting Mileage Fraud?
An accidental low estimate rarely triggers a penalty on its own. Insurers usually correct the figure and adjust your premium at renewal, says Buddy Parkhurst, a licensed insurance agent at Insurify.
"Some companies will ask for you to verify your annual mileage via oil change receipts, which show your average mileage between changes. Other insurers may offer telematics tracking, which will confirm annual mileage for you," said Buddy Parkhurst, licensed insurance agent at Insurify.
Deliberate understatement carries sharper teeth. When an insurer decides a misstatement was material, it can deny a claim or void the policy as if it never existed, MoneyGeek reports, and intent does not always shield the policyholder once a court weighs the facts. Insurers also hold the right to pull mileage from repair-shop or DMV records while a policy stays active.
Guessing a little low by accident typically costs you a higher premium at renewal once the insurer recalculates. Knowingly reporting 7,000 miles while driving 18,000 is different: a material misrepresentation can let the carrier deny a collision claim or cancel coverage outright. Update your estimate the moment a new job, move, or longer commute changes your driving.
What You Should Do Now
Pull your declarations page
Log into your insurer's portal and find the annual mileage figure listed on your policy; many drivers never notice the number an agent entered years ago.
Recalculate from the odometer
Note a typical month's driving, multiply by 12, and compare that total against the figure on file before your next renewal date.
Claim the discount if you drive little
Submit oil-change receipts or odometer photos to lock in a low-mileage discount; some carriers backdate the savings to your policy's start once you prove the lower number.
Compare three quotes
Every insurer weights mileage differently, so a driver hit with a mileage-driven increase can often recover the difference by shopping at least three carriers.
Looking Ahead
Telematics adoption keeps climbing, and usage-based programs now verify mileage in real time rather than trusting a one-time estimate. As more carriers plug into odometer feeds and connected-car data, the 44% gap between reported and actual mileage looks harder to sustain. Drivers who report accurately today avoid the renewal shock that catches those who guessed low.
Frequently Asked Questions
Not much on its own. Insurify pegs the difference at about $3 to $5 a month for every extra 2,000 to 3,000 miles, and roughly $264 a year separates drivers under 5,000 miles from those over 15,000. The small saving rarely outweighs the risk of a corrected premium or a denied claim.
Yes, if the misstatement is material and deliberate. MoneyGeek reports that insurers can treat a knowingly false mileage figure as misrepresentation, which allows them to deny a claim or cancel the policy. An honest underestimate usually just leads to a higher premium at renewal.
Carriers confirm mileage through odometer photos at sign-up or renewal, oil-change and service receipts, telematics apps in pay-per-mile programs, and DMV or repair-shop records they can access while your policy is active.
Long distances between work, healthcare, and groceries make annual mileage hard to estimate. Wyoming drivers averaged 25,779 actual miles but reported 6,969, a 73% gap. Nine of the 10 worst-underreporting states also have above-average poverty rates, which adds pressure to keep premiums down.
Submit proof such as odometer photos or oil-change receipts and ask your insurer about a low-mileage discount, which can cut 10% to 30% off your rate. Some carriers backdate the savings to your policy's start date once you document the lower mileage.
