Uninsured motorist coverage rules in Alabama

Getting hit by a driver who has no insurance, or nowhere near enough of it, is common here. The Insurance Research Council estimated that about one in seven Alabama drivers, 14.2% in 2022, carried no liability coverage at all, right around the national rate.¹ When that person causes your crash, uninsured motorist coverage on your own policy is often the only real source of money for your medical bills and lost wages. Uninsured motorist (UM) coverage answers when the at-fault driver had no policy; underinsured motorist (UIM) coverage answers when they had one but its limits were too small to cover what you lost. Alabama handles both under a single statute, and the details below are what separate a paid claim from a denied one.

It's already in your policy unless you signed it away

Alabama does not force you to buy this coverage, but it does force your insurer to include it. Every auto liability policy issued in the state has to provide UM coverage at the same bodily-injury limits as the mandatory liability minimum, unless the named insured rejects it in writing.² Those minimum limits are $25,000 per person and $50,000 per accident for bodily injury.³

The default, then, is that you have it. If you never signed a written rejection, the coverage is there even if you don't remember buying it. That rule matters after a crash. When an insurer claims a driver waived UM, it has to produce the signed rejection, so pull your declarations page and your original application and check. UM here covers bodily injury, meaning medical bills, lost income, and pain and suffering; it does not automatically pay for damage to your car, which rides on separate coverage. The protection generally follows you and your resident family members, whether you were driving, riding as a passenger, or on foot when an uninsured driver hit you.

What counts as uninsured includes underinsured

Alabama's statute defines an "uninsured motor vehicle" broadly, and that definition is where UIM coverage lives. Four situations count²:

• neither the owner nor the driver carried bodily-injury liability insurance;
• the at-fault driver's liability limits were below the state minimum;
• the at-fault driver's insurer became insolvent after the policy was issued; or
• the total liability coverage available is less than the damages you are legally entitled to recover.

That last category is underinsurance. Alabama folds it into the same coverage, so one UM/UIM policy responds whether the other driver had nothing or simply not enough.² The coverage also reaches hit-and-run crashes where the at-fault driver is never identified, which is one reason to make sure the wreck is on the record in the official Alabama crash report.

How UIM coverage actually pays

UIM is gap coverage, and Alabama applies a setoff. Your own carrier gets credit for the at-fault driver's liability limits and covers the difference above that, up to your UIM limit.⁴ In State Farm Mutual Automobile Insurance Co. v. Motley, the Alabama Supreme Court narrowed that credit: your carrier can only set off the coverage on the vehicle that actually hit you, not liability insurance carried by some other party who might share the blame, such as a company responsible for maintaining the road.⁴

In plain terms, if the driver who hit you carried only the $25,000 state minimum and your medical bills reach $90,000, you collect that $25,000 from their insurer and then look to your own UIM coverage for much of the rest, up to your policy limit. That math is also the argument for carrying UIM limits well above the state floor, because the coverage only helps to the extent your limit runs past what you already recovered.

Stacking is allowed, up to three vehicles

If you insure more than one vehicle on the same policy, Alabama lets you stack UM coverage. The statute limits recovery to the primary coverage plus whatever additional coverage applies to other vehicles, but not more than two additional coverages within a single contract.² That caps stacking inside one policy at three vehicles' worth of limits. A policy covering three cars at $50,000 each can therefore reach up to $150,000 of UM protection for one injury, unless the policy contains valid language limiting it.

Tell your own insurer before you settle

This is the trap that quietly costs people their UIM claim. Before you accept a settlement from the at-fault driver's liability insurer and sign a release, you have to give your own UIM carrier notice and a chance to protect itself. The rule comes from Lambert v. State Farm Mutual Automobile Insurance Co.⁵ Once you have a liability settlement offer in hand, you notify your UIM carrier, and it can either consent to the settlement or advance you that same amount itself to preserve its right to pursue the at-fault driver.⁵ Settle and release the at-fault driver without giving that notice, and you can forfeit your own UIM claim.

The deadlines that can end your claim

Two clocks start the day of the crash. Your claim against the at-fault driver is a personal-injury claim, and you have two years from the crash date to file it.⁶ Your claim against your own insurer for UM/UIM benefits is a contract claim, which carries a six-year limit.⁷

For years, when that six-year clock started was an open question. The Alabama Supreme Court answered it in 2024 in Ex parte State Farm Mutual Automobile Insurance Co.: a direct UM/UIM claim against your insurer accrues on the date of the accident, not on some later date when the company denies you.⁸ The injured party there filed her UIM claim just over six years after the wreck and lost it as time-barred.⁸ So don't read the six years as breathing room. You can name the at-fault driver and bring your UM carrier into the same case, but the safest approach is to treat the two-year deadline as your real one, put your carrier on notice early, and check whether your policy imposes an even shorter contractual limit.

What to do next

Read your declarations page and confirm your UM and UIM limits before you say much to any adjuster. Report the crash promptly so the at-fault driver, or the fact that one fled, is documented while the trail is fresh. When the injuries are serious or the insurer starts disputing coverage, the setoff, stacking, and notice rules turn technical fast, and it is worth talking with an attorney who handles these claims. If the wreck also damaged your vehicle, Alabama's rules on lost resale value are covered separately.
