Short answer: When you are injured while riding in a friend’s car, Louisiana generally treats the uninsured motorist coverage on that car as primary. If your damages exhaust that primary coverage, you may use one other UM policy available to you as excess coverage. Louisiana does not ordinarily let you combine every UM policy in your household.
The Occupied Vehicle’s UM Coverage Comes First
Louisiana Revised Statutes 22:1295(1)(c) establishes the priority rule. For an injured person occupying a vehicle that is not owned by that person, a resident spouse, or a resident relative:
- The UM coverage applicable to the occupied vehicle is primary.
- After that primary coverage is exhausted because of the passenger’s damages, one other UM coverage available to the passenger may apply as excess.
- No more than one coverage from more than one UM policy may serve as excess above the primary coverage.
This is a limited exception to Louisiana’s general rule against stacking multiple UM coverages. The Louisiana Supreme Court applied this exception in Courville v. State Farm, allowing the injured occupant to use the host vehicle’s primary UM coverage and then one other available UM policy.
A Simple Example
You are a passenger in a friend’s car when an uninsured driver crosses the centerline. Your damages are reasonably valued at $175,000. The friend’s car has $50,000 in UM bodily injury coverage. You are also an insured under your own $100,000 UM policy.
The friend’s $50,000 UM coverage is considered first because it applies to the occupied vehicle. If your proven damages exhaust that limit, your policy may provide up to another $100,000 as excess coverage, subject to its terms. The fact that you also live with a parent who has a separate UM policy does not ordinarily allow you to add that third policy too. Louisiana permits only one excess UM coverage above the primary coverage.
Policy limits are ceilings, not automatic payments. You still must prove fault, coverage, causation, and the amount of your damages.
What Does It Mean to Exhaust the Primary UM Coverage?
The statute permits resort to excess UM when the primary UM coverage has been exhausted due to the extent of the passenger’s damages. In practice, the primary carrier’s declarations, per-person and per-accident limits, payments to other injured occupants, and settlement documents all matter.
A passenger should not assume that a policy with a $100,000 limit has $100,000 available to that passenger. A per-accident limit may be shared by several injured people. Prior payments can reduce what remains.
What if the Friend’s Car Has No UM Coverage?
Your own UM policy may still cover you if you qualify as an insured and no exclusion applies. But the absence of UM on the occupied car does not create a right to stack several personal policies. Louisiana decisions have explained that the statutory exception allowing primary plus one excess policy depends on primary UM coverage applicable to the occupied vehicle. When there is no such primary coverage, the exception to the anti-stacking rule may not apply.
This issue requires careful policy review. A policy that follows the passenger may itself provide coverage applicable to the non-owned car, and cases involving temporary substitute vehicles can produce a different classification. Do not decide the issue from the insurance card alone.
What if the At-Fault Driver Is Underinsured Instead of Completely Uninsured?
UM coverage in Louisiana also addresses an underinsured motorist whose liability coverage is insufficient to compensate the insured’s damages. The at-fault driver’s liability coverage is normally pursued first. UM then addresses the uncompensated damages within the applicable coverage and limits.
Louisiana UM is generally add-on coverage, meaning the claimant does not simply subtract the tortfeasor’s liability limit from the UM limit. The total recovery still cannot exceed the damages proven, and policy and settlement issues can affect the result.
What if the Friend Driving the Car Was Also at Fault?
The host driver’s liability coverage may be relevant if that driver shares legal fault for the crash. That liability claim is distinct from a UM claim based on the uninsured or underinsured driver’s fault. Louisiana’s current comparative fault law may also reduce or bar recovery depending on the accident date and allocation of fault.
Every potentially responsible driver, vehicle owner, employer, and insurer should be identified before releases are signed.
The Non-Owned Vehicle Requirement Matters
The primary-plus-one-excess exception applies when the injured person occupies a car not owned by the injured person, the person’s resident spouse, or a resident relative. A friend’s car will often satisfy that requirement, but labels do not control ownership or residency.
For example, a car titled to a parent who lives in the passenger’s household is not treated the same as an unrelated friend’s car. A company vehicle, leased vehicle, rental, or temporary substitute vehicle can require examination of the ownership facts and the policies that apply to that specific vehicle.

How to Find Every Potential UM Policy
A proper search should include:
- The complete policy on the vehicle in which you were riding
- Your personal automobile policy
- Policies issued to a resident spouse or resident relatives
- Any employer or commercial policy connected to the trip
- Umbrella or excess policies that may contain relevant coverage
- UM selection or rejection forms for every potentially applicable policy
A policy’s existence does not make it available. The passenger must be an insured under its wording, the coverage must not have been validly rejected, and the claim must fall within its terms.
Do Not Miss Louisiana’s UM Deadline
Louisiana Revised Statutes 9:5629 generally provides two years from the accident for an action seeking damages under UM coverage. Negotiations or an open claim file should not be assumed to stop that clock. Other claims arising from the same crash can have different deadlines.

Before signing a release
Passenger claims can involve several policies but a strict order of recovery. Obtain the declarations, complete policy forms, UM selection or rejection forms, and any proposed release before deciding that a particular layer of coverage is unavailable.
