The Question Every Multi-Car Household Asks
You just added a second car to your Indiana policy, and the quote came back higher than expected. Buried in the coverage breakdown is a line item for uninsured motorist coverage on both vehicles. You know Indiana doesn't require it—so why is it on the quote, and can you drop it to lower the premium?
The answer hinges on a structural quirk most households miss: Indiana law requires every carrier to offer uninsured motorist coverage when you buy liability insurance, and declining it requires a signed waiver. On a multi-car policy, that waiver applies per vehicle, not once for the whole policy. If you don't explicitly decline UM for each car, the carrier includes it by default—and you pay for it on every vehicle.

14%
One in seven drivers on Indiana roads carries no liability insurance, meaning an at-fault uninsured driver cannot pay your medical bills or repair costs after a collision. Uninsured motorist coverage fills that gap.

What Uninsured Motorist Coverage Actually Does
Uninsured motorist coverage pays your medical expenses, lost wages, and vehicle damage when an at-fault driver has no insurance or flees the scene. It also covers you if the at-fault driver's liability limits are too low to cover your costs—that's the underinsured motorist component, often bundled with UM.
Indiana splits UM into two parts: uninsured motorist bodily injury (UMBI) covers medical bills and lost income, while uninsured motorist property damage (UMPD) covers vehicle repair or replacement. UMBI is the more common add-on; UMPD is optional and less frequently purchased because collision coverage already handles vehicle damage regardless of fault.
On a multi-car policy, UM coverage applies per person and per accident, not per vehicle. You do not need separate UM limits for each car—but the carrier charges a premium for UM on each vehicle because the exposure increases with every car you insure.
Indiana carriers must offer UM coverage when you buy liability insurance, and declining it requires a signed waiver for each vehicle on your policy.
How UM Coverage Works Across Multiple Vehicles
When you add a second or third vehicle to your Indiana policy, the carrier includes uninsured motorist coverage on each car unless you sign a waiver declining it. Declining it is your right, but it must be documented.
The premium for UM coverage increases with each vehicle because the carrier's exposure grows—more cars mean more opportunities for an uninsured driver to hit one of your vehicles. But the coverage itself does not stack per vehicle. If two household members are injured in separate accidents with uninsured drivers, each claim is subject to the same per-person and per-accident limits, regardless of how many cars you insure.

When Declining UM Coverage Costs More Than Buying It
Declining UM coverage makes sense only when every household member carries health insurance with low out-of-pocket maximums and you carry collision coverage on every vehicle. Even then, UM covers lost wages and pain-and-suffering damages that health insurance does not—and collision coverage requires you to pay your deductible before the carrier repairs your car.
The math shifts on a multi-car policy. Indiana's 14% uninsured-driver rate means the risk is not hypothetical—it is a structural feature of driving here.
Carriers writing multi-car policies in Indiana include uninsured motorist coverage by default because the actuarial data shows households with multiple vehicles face higher exposure to uninsured drivers. Declining it requires you to affirmatively opt out, and most households do not because the premium difference is smaller than the deductible on a single claim.
Indiana Minimum Liability Limits
$25,000 / $50,000
Indiana requires $25,000 bodily injury per person and $50,000 per accident, the same limits most carriers offer as the default UM floor. Declining UM means an uninsured driver's lack of coverage leaves you responsible for costs above these minimums.

Structuring UM Coverage for a Multi-Car Household
Buy UM limits equal to your liability limits. Mismatched limits create a gap: you are protected when you cause the accident but not when someone else does.
If you decline UM on one vehicle, you decline it on all vehicles—most carriers do not allow partial UM coverage on a multi-car policy. The waiver applies at the policy level, not the vehicle level, so you cannot keep UM on your daily driver and drop it on a rarely-driven third car. The structural choice is binary: UM on every car or UM on none.
Compare Carriers That Write Multi-Car Policies in Indiana
Not every carrier prices UM coverage the same way on multi-car policies. Some apply a flat per-vehicle charge; others scale the premium based on the vehicle's value and usage. Comparing quotes from carriers writing Indiana multi-car policies—Geico, State Farm, Progressive, Allstate, and Nationwide among them—shows you which structure costs less for your household's specific vehicle mix.
Request quotes with UM included and with UM declined. The difference tells you the annual cost of the coverage, and you can weigh that against the $25,000/$50,000 minimum liability limits an uninsured driver will not have. Most households find the premium difference smaller than expected and keep the coverage because the downside risk is concrete and the savings are modest.
