Pay-as-you-go auto insurance: how it works and who it fits
Last reviewed September 6, 20265 min readBy the Goodsurance editorial team Reviewed by the Goodsurance editorial team
Pay-as-you-go auto insurance, also called usage-based insurance or UBI, sets your premium based on how much you drive rather than charging a flat rate for a policy period. Most programs connect to your vehicle through a mobile app or a small plug-in device that logs miles and, in many programs, driving behaviors such as hard braking and late-night trips.
What pay-as-you-go auto insurance actually charges you
The billing structure varies, but the underlying logic is consistent: drivers who put fewer miles on their cars have fewer opportunities to be involved in a crash. That logic has real support in how crashes distribute across the road. According to the National Highway Traffic Safety Administration, property-damage-only crashes made up 72% of all police-reported crashes in the US in 2024, representing 4,467,244 of 6,180,241 total incidents. Every mile driven is another opportunity for that kind of contact, which is what makes mileage a reasonable variable for pricing risk.
Two broad structures exist within the pay-as-you-go category:
Pay-per-mile: You pay a base rate per month plus a per-mile charge. Your bill reflects exactly how far you drove. Fewer miles means a lower total.
Behavior-based (telematics) programs: Your premium adjusts based on a driving score that accounts for speed, braking, acceleration, and time of day. Mileage may factor in as well, but it is not the sole variable.
Some programs blend both approaches. Before enrolling in any program, confirm which model it uses, because the distinction changes how much control you have over your final cost.
Most US crashes cause only property damage. That is why mileage is a fair way to price your risk.
Who tends to benefit and who may not
Pay-as-you-go insurance tends to work best for people who drive significantly fewer miles than the national average. Remote workers, retirees who have consolidated to one car, and city dwellers who use a vehicle mainly on weekends are among the most commonly cited candidates. If your vehicle spends more days parked than moving, a per-mile or behavior-based structure can align your premium more closely with your actual risk exposure.
Drivers who commute daily or log high mileage for any reason should compare carefully before switching. At high mileage, a per-mile rate can exceed the cost of a traditional flat-rate policy. Behavior-based programs can also penalize drivers whose schedules require nighttime or early-morning travel, even if those drivers have clean records.
Scenarios where pay-as-you-go tends to underperform:
- Households with a secondary vehicle that sits unused but still needs to be insured
- Drivers in states where carrier participation in UBI programs is limited
- Anyone uncomfortable with an app or telematics device continuously tracking location and driving patterns
Privacy is a practical concern, not a theoretical one. Most programs transmit driving data to the carrier on an ongoing basis. Read the data-use disclosures before enrolling, particularly around how the carrier may use your data for future underwriting decisions at renewal or after a claim.
State minimums still apply no matter how you pay
The payment structure of a policy does not change what the law requires you to carry. Every state mandates a minimum level of liability coverage, and pay-as-you-go policies must meet those thresholds the same way a traditional policy does.
California's requirements offer a useful illustration of how state floors can shift. Effective January 1, 2025, California raised its minimum auto liability limits to $30,000 bodily injury per person, $60,000 per accident, and $15,000 for property damage, the first increase in 56 years, according to the California Department of Insurance. That change affects every California driver's coverage baseline regardless of whether they pay monthly, per mile, or annually.
State minimum liability covers damage and injury you cause to others. It does not cover your own vehicle or your own injuries. Drivers who want protection for their own car, whether on a traditional policy or a pay-as-you-go program, still need to evaluate collision, comprehensive, and any other coverages separately. The payment structure changes how your premium is calculated, not what each coverage type actually does.
Pay-as-you-go plans in California must still meet the new 30/60/15 liability floor, just like any other policy.
What to verify before you switch
If pay-as-you-go looks like a fit, confirm a few things with any specific program before canceling your existing policy:
Coverage continuity: Make sure there is no gap between your old policy's end date and your new policy's start date. Even a short lapse can affect your rate on future policies.
How the minimum rate works: Many per-mile programs charge a base daily or monthly rate even when you do not drive. Understand what that floor is and whether your low-mileage savings still net out favorably after accounting for it.
What happens if you drive more than expected: Some programs cap per-mile charges at a daily maximum. Others do not. If you take an extended road trip in a given month, confirm how the program handles that before it appears on your bill.
Monitoring requirements: Find out what device or app is required, whether it affects your phone's battery or requires a hardware installation, and what the carrier does if you lose connectivity or opt out of monitoring mid-term.
Cancellation terms: Some programs require minimum policy terms or assess early-cancellation fees. Read the policy documents, not just the marketing summary.
Questions to ask before you sign up
Will my new policy start the same day my old one ends?
Even one day without coverage can raise your rates on future policies.
What is the lowest amount I will be charged if I do not drive at all?
Most programs charge a base daily or monthly rate even with zero miles.
Is there a cap on per-mile charges if I take a long trip?
Some programs cap charges at a daily max. Others do not. Know before you go.
What app or device is required, and what happens if I lose connectivity?
Find out if opting out of monitoring mid-term changes your rate or coverage.
Are there fees for canceling early?
Some programs require a minimum term. Read the policy documents, not just the ads.
How to compare options in your state
UBI program availability varies by state and carrier, so comparing options is less straightforward than comparing standard policies. Your state's department of insurance website is the most reliable starting point for confirming which carriers are licensed to operate and what programs they have filed for approval. State regulators review program filings, which means what a carrier offers in California may differ substantially from what it offers in Texas or Florida.
The National Association of Insurance Commissioners (NAIC) publishes consumer resources and market data that can help you understand what carriers are active in your market and what your state regulator oversees.
When you request quotes, ask each carrier to clarify: whether their UBI program affects your base rate immediately or only at renewal, how disputed mileage readings are handled, and whether the telematics data can be used in the carrier's favor if you file a claim.

What is collision coverage on a car insurance policy?
Collision coverage is the part of a car insurance policy that pays for damage to your own car after a crash.
It applies when your car hits another vehicle or an object, and when your car flips over. You choose a deductible, which is the share of the repair bill you pay before the insurer pays the rest. Collision is optional in most cases, but a lender or a leasing company often requires it while you still owe money on the car.
Do I need collision coverage if my car is paid off?
It depends.
Once the loan is paid off, no lender can require collision coverage, so the choice is yours. Ask yourself one question: if your car were wrecked tomorrow, could you replace it out of pocket without hurting your household? If the answer is no, collision still does real work. If the car is old and worth little, the claim payment may be small, since collision pays based on what the car is worth, not what a new one costs.
What does comprehensive car insurance cover?
Comprehensive covers damage to your car that does not come from a crash with another vehicle or an object.
Think of it as protection from events you cannot steer around. That includes theft, fire, hail, falling tree limbs, flooding, vandalism, and hitting an animal on the road. Broken glass usually falls here too. You pick a deductible, which is the part of the bill you pay before the insurer pays the rest. Comprehensive is optional unless a lender requires it.
Does comprehensive insurance cover a cracked windshield?
Yes.
Glass damage is usually handled under comprehensive, not collision, because a rock or road debris is not a crash. If a stone chips your windshield on the highway, that is a comprehensive claim. Your deductible still applies, which is the share of the bill you pay first. Some states require insurers to offer glass coverage with a lower deductible or none at all, and those rules vary by state. Fixing a small chip early usually costs less than a full replacement.
What happens if a deer runs into my car?
Hitting an animal is normally a comprehensive claim, not a collision claim, even though it feels like a crash.
Comprehensive covers the damage the animal caused to your car, minus your deductible. There is an odd twist: if you swerve to miss the deer and hit a tree or a ditch instead, that becomes a collision claim, because you struck an object. Report the incident to your insurer either way, and take photos of the damage before any repairs begin.
What is the difference between comprehensive and collision insurance?
Both pay for damage to your own car, but they split the world in two.
Collision handles crashes: hitting another vehicle, hitting an object like a pole or a guardrail, or rolling your car over. Comprehensive handles almost everything else: theft, fire, hail, flooding, vandalism, falling branches, and hitting an animal. Each one carries its own deductible, which is the part of the bill you pay before the insurer pays. You can buy them together or, in many cases, separately.
Is a stolen car covered by collision insurance?
No.
Theft falls under comprehensive coverage, not collision. Collision only pays when your car strikes another vehicle or an object, or when it rolls over. If your car is stolen and never found, comprehensive pays what the car was worth at the time it was taken, minus your deductible. If it is recovered with damage, comprehensive covers the repairs. File a police report first, since insurers ask for the report number when they open a theft claim.
Can I buy comprehensive without collision?
It depends on the insurer and on whether you owe money on the car.
Many insurers will sell comprehensive alone, since it covers theft, fire, and weather damage while the car sits parked. Buying collision alone is far less common. If a lender or a leasing company holds the title, it usually requires both, and that rule sits in your loan or lease contract, not in state law. Ask your insurer which pairings it allows before you drop a coverage.
What does an HO-6 condo insurance policy cover?
An HO-6 is the policy written for a condo owner.
It covers the parts of the home you own and the association does not: interior walls, flooring, cabinets, fixtures, and built in features, depending on how your association documents split things. It also covers your belongings, your liability if someone is hurt in your unit, and a place to stay if a covered loss makes your unit unlivable. Many policies add loss assessment coverage for your share of a building claim.
Do I need condo insurance if the building already has a master policy?
Yes.
In almost every case you still need your own policy. The master policy the association buys covers the building shell and shared areas like hallways, the roof, and the lobby. It does not cover what is inside your unit, your belongings, or your personal liability. Read your association bylaws to see where the master policy stops, since the dividing line differs from building to building. An HO-6 policy fills that space. Lenders usually require one before they will finance a condo.
What is loss assessment coverage on a condo policy?
When a covered loss hits the shared parts of a condo building and the master policy does not pay all of it, the association can bill each owner a share.
That bill is called an assessment. Loss assessment coverage is the piece of your HO-6 policy that helps pay your share. It applies to assessments tied to a covered loss, not to routine repairs or normal upkeep. Coverage amounts and rules vary by policy, so check your declarations page.
Does collision coverage pay if I hit a tree?
Yes.
Collision coverage pays to fix or replace your car when it crashes into an object or another vehicle. A tree counts as an object. It also applies if you hit a fence, a pole, or a guardrail, or if your car rolls over. You still pay your deductible first, which is the part of the repair bill you cover. Collision pays for your car damage even when the crash is your fault. It does not pay for the other driver's car.
