Uninsured motorist coverage rules in North Carolina

If the driver who hit you carried no insurance, or sped off before you got a plate number, the money for your injuries often has to come from your own policy. That is what uninsured motorist coverage does. North Carolina does not leave it optional: every auto liability policy sold in the state has to include it.

The reason matters. Nationally, about one in seven drivers (15.4%) had no insurance in 2023, and roughly one in three was either uninsured or underinsured, according to the Insurance Research Council.¹ North Carolina holds that gap down by building the protection into every policy. What follows is what the coverage looks like here, what changed in 2025, and the steps you have to take to actually collect.

It is already built into your policy

Two coverages come standard. N.C. Gen. Stat. § 20-279.21(b)(3) requires uninsured motorist (UM) coverage on every bodily injury liability policy issued in the state, and § 20-279.21(b)(4) requires underinsured motorist (UIM) coverage.² The North Carolina DMV puts it in plain terms: UM and UIM coverage is required on all policies, even those written above the minimum.³

Your UM limits are tied to the bodily injury liability limits on your own policy. They start at the state minimum, and you can raise them, up to a statutory cap of $1,000,000 per person and $1,000,000 per accident.² What you cannot do is buy UM for less than your own liability limits.²

What changed on July 1, 2025

Two laws reset the numbers. Session Law 2023-133 raised North Carolina's minimum liability limits from 30/60/25 to 50/100/50: $50,000 for injury to one person, $100,000 for injuries to more than one person in a single crash, and $50,000 for property damage.⁴³ Session Law 2024-29 then rewrote how underinsured coverage is calculated.⁵ Both apply to policies written or renewed on or after July 1, 2025.³

Because UM and UIM follow your liability limits, the higher floor pulled them up too. A minimum policy now carries at least $50,000 per person and $100,000 per accident of protection against an uninsured driver, up from $30,000 and $60,000 before.²³

Session Law 2024-29 also changed the underinsured offset. The statute now says UIM coverage "is deemed to apply to the first dollar of an underinsured motorist coverage claim beyond amounts paid to the claimant under the exhausted liability policy."⁵ That language replaced the older rule that let an insurer credit the at-fault driver's payment against your UIM limit, so the liability payout no longer shrinks your underinsured recovery the way it once could.⁵

How much it actually pays

For a driver with no insurance at all, or a hit-and-run, UM pays your damages up to your UM limit.² Underinsured coverage is narrower. It only helps when the at-fault driver had insurance but not enough, meaning their liability limits are lower than your UIM limits.⁶ The Department of Insurance describes UIM as paying "the difference between the other driver's Liability limits and your UIM limits."⁶

A quick example. Say your injuries come to $80,000, the driver who hit you carried a $30,000 minimum policy, and you carry $100,000 in UIM. Their insurer pays its $30,000, and your own UIM coverage can cover the remaining $50,000.²⁶ If you and the at-fault driver both carry the same limits, though, UIM adds nothing, because there is no gap to fill.

Two details are easy to miss. Uninsured motorist coverage includes property damage, but that piece carries a $100 deductible under the statute.²⁶ Underinsured coverage does not pay for vehicle damage at all; it is bodily injury only.⁶ A damaged or devalued car is a separate claim (see diminished value in North Carolina).

Hit-and-run and phantom drivers

North Carolina lets you file a UM claim when the at-fault driver cannot be identified, but the statute sets conditions. The claim has to come from a "collision between motor vehicles," so there generally has to be actual contact; a car that forced you off the road without touching you usually will not qualify.² You also have to report the crash "within 24 hours or as soon thereafter as may be practicable" to a police officer or the Commissioner of Motor Vehicles, and give your insurer notice of the injury within a reasonable time.² Get the police report going right away (here is how North Carolina crash reports work).

Tell your own insurer before you settle

This is the step people get wrong. If the at-fault driver's insurer offers you its full limits, do not sign the release until your own UIM carrier knows. The statute requires written notice of any tentative settlement to your UIM insurer, and gives that insurer 30 days to advance you the settlement amount if it wants to keep its right to pursue the at-fault driver.² Pay you within 30 days, and it preserves that right while you keep your UIM claim; miss the window, and you can take the liability settlement without losing UIM.² Signing a release first can erase the underinsured claim.

There is a matching rule for uninsured claims. Your UM insurer can be served as an unnamed party and becomes part of the lawsuit even though it is not listed in the caption, and no suit can begin until 60 days after you post notice to the insurer.²

Stacking, and who counts as covered

If you insure several cars on one policy, you cannot add the UM limits of each car together.² But if you are covered under more than one policy, say your own plus a resident parent's, you can combine the highest UM limit available under each, for nonfleet private passenger vehicles.² UIM follows the same no-single-policy-stacking rule.²

Coverage reaches well past the named insured. The statute defines "persons insured" to include the named insured, a resident spouse, resident relatives, permissive drivers, and passengers.² And if the at-fault driver was insured but their company goes insolvent within three years of the crash, their vehicle is treated as uninsured and your UM coverage steps in.²

Deadlines

These claims ride on the underlying injury case, and North Carolina gives you three years from the date of the crash to file a personal injury lawsuit under N.C. Gen. Stat. § 1-52(5).⁷ Let that deadline pass and the UM or UIM claim built on it usually goes with it. Between the settlement-notice steps and the reality that a UM claim can mean suing your own insurer, this is a good place to get a lawyer involved early; you can start with the legal directory.
