You’re stopped at a light when someone runs into you. The driver who hit you was in a car that belongs to their roommate. Now you’re hurt, your car is damaged, and you’re trying to figure out whose insurance pays after a borrowed car accident in Louisiana. The answer matters a great deal — and it’s more complicated than most people expect. Usually you have two years to pursue your claim under La. C.C. Art. 3493.1.
In Louisiana, Insurance Follows the Car First
Louisiana follows permissive use doctrine. When the car owner gives someone permission to use their vehicle — express or implied from a pattern of prior use — the car owner’s insurance policy is the primary coverage. The driver’s own insurance, if they have any, is typically secondary.
What this means for you as the injured party: your claim goes first against the car owner’s liability policy, even though the car owner wasn’t driving. If that policy’s limits are exhausted, the driver’s own insurance may provide additional coverage.
What If the Driver Didn’t Have Permission?
If the driver took the car without the owner’s knowledge or permission — what Louisiana law calls an unauthorized user — the owner’s insurance may deny coverage entirely. In that situation, the driver’s own policy would be primary, assuming they have one. If neither applies, your own uninsured motorist coverage becomes critical.
Whether permission existed is often disputed. A car owner who regularly let someone borrow the car may deny giving permission for that specific trip. These disputes get resolved by looking at the history of the relationship and prior use of the vehicle — which is exactly why early investigation matters.
Your Uninsured Motorist Coverage Matters More Than You Think
Louisiana law requires insurers to offer UM/UIM coverage, though drivers can reject it in writing. If the car owner’s policy has low limits, the driver has no insurance, or coverage is disputed, your own UM coverage fills the gap. This is one of the most underutilized protections in Louisiana auto insurance — and one of the most important in exactly this type of situation.

Frequently Asked Questions
Can I sue the car owner even if they weren’t in the vehicle?
Potentially. Under Louisiana’s permissive use doctrine, a car owner who gave permission for someone to use their vehicle can be held liable through their insurance for injuries that driver causes. The owner may also bear personal liability in certain circumstances — such as knowing the driver was impaired or unlicensed.
What if both the driver’s and the car owner’s insurance deny coverage?
Coverage disputes between insurers are common in borrowed-car crashes. An attorney can engage both carriers simultaneously and pursue your own UM/UIM policy if needed. Having an attorney manage these negotiations prevents any single insurer from stalling while your claim sits.
Does Louisiana require car owners to insure their vehicles?
Yes. Louisiana requires minimum liability coverage on all registered vehicles. However, minimum limits — $15,000 per person / $30,000 per accident — are often insufficient for serious injury claims. That gap is exactly why UM coverage on your own policy is so valuable.
