Uninsured Motorist Coverage: What It Means
Uninsured motorist coverage pays for your injuries, and in some states your car's damage, when a driver who is at fault has no insurance at all. Underinsured motorist coverage does the same when the at-fault driver does carry insurance but their limits are too low to cover your losses.
Liability coverage pays when you are at fault. Uninsured and underinsured motorist coverage protect you in the opposite case - when someone else causes the crash but cannot pay for the harm they did. It typically covers medical bills, lost wages, and similar costs for you and your passengers, up to the limits you choose.
When it applies and where it is required
Uninsured motorist coverage steps in when the at-fault driver has no policy, when their insurer denies the claim, or in many states in a hit-and-run where the driver is never found. Underinsured motorist coverage applies when the at-fault driver's liability limit is lower than your injury costs, paying the difference up to your own limit. Some states require one or both of these coverages, and others require insurers to offer them so you can decline in writing. Because a meaningful share of drivers on the road carry no insurance or only the bare state minimum, this coverage is one of the more cost-effective ways to protect yourself against losses you did not cause and cannot otherwise recover.
A real example of an uninsured-motorist claim
A driver runs a red light, injures you badly enough for $60,000 in medical bills and lost wages, and turns out to carry no insurance at all. Liability coverage does nothing here — it pays only when you are at fault. Uninsured motorist coverage with a $100,000 limit steps into the at-fault driver's place and pays your $60,000 in losses. Without it, you would be chasing an uninsured stranger for money they almost certainly do not have.
Why uninsured-motorist coverage matters on real roads
A large share of drivers carry no insurance or only bare-minimum limits, and you cannot choose which of them hits you. Uninsured and underinsured motorist coverage is the only part of your policy that pays for serious injuries someone else caused but cannot cover — including, in many states, a hit-and-run where the driver is never found. It is typically inexpensive because it pays only in that narrow situation, which makes it one of the highest-value dollars on a policy for the protection it buys.
Frequently asked questions
Is uninsured motorist coverage required?
It depends on your state. Some states require uninsured or underinsured motorist coverage; many others require insurers to offer it, and you can reject it in writing. Check your state's rules or your policy declarations.
Does it cover a hit-and-run?
In many states, yes — uninsured motorist coverage applies when an at-fault driver flees and is never identified, though the exact rules and any property-damage limits vary by state.
