The Multi-Car Premium Question
You added a second or third vehicle to your Louisiana policy and watched the premium climb more than expected, or you're shopping before the next car arrives and trying to understand what actually moves the number. The multi-car discount exists, but it's one input among many, and households with several vehicles on one policy often discover that per-vehicle coverage decisions—liability limits, collision and comprehensive elections, deductible levels—compound across the policy in ways a single-car household never sees.
Louisiana law requires $15,000 per person and $30,000 per accident in bodily injury liability, plus $25,000 in property damage liability. Those minimums anchor every policy, but the rate difference between minimum coverage and higher limits, between carrying collision on every vehicle versus selectively, and between a $500 deductible and a $1,000 deductible multiplies when you're covering three cars instead of one. This article walks the structural levers that control premium for multi-vehicle Louisiana households.

$15,000/$30,000/$25,000
Every Louisiana auto policy must carry at least $15,000 per person and $30,000 per accident in bodily injury liability, plus $25,000 in property damage liability. These minimums apply to each vehicle on the policy, and raising them is the first structural rate lever available.

Why the Multi-Car Discount Isn't the Whole Story
Carriers advertise multi-car discounts, and they're real: insuring two or more vehicles on one policy typically costs less per vehicle than insuring each separately. But the discount applies to a base rate that's built from each vehicle's coverage profile—year, make, model, how it's used, where it's garaged, and what coverage you carry on it. A household that elects full coverage with low deductibles on three vehicles will pay more after the multi-car discount than a household that carries minimum liability on two older cars and full coverage on one newer one, even if the second household gets a smaller discount percentage.
The rate levers that matter most for multi-vehicle households are per-vehicle coverage decisions and deductible structure. Louisiana does not mandate uninsured motorist coverage or personal injury protection, so those are optional add-ons. Collision and comprehensive are required only if you finance or lease the vehicle. Once a car is paid off, you can drop collision and comprehensive without violating state law, and that decision affects only that vehicle's portion of the premium, not the others.
The structural reality: the multi-car discount reduces the combined premium, but the combined premium is the sum of each vehicle's individual rate. Controlling the rate means controlling what you carry on each car.
The multi-car discount applies after per-vehicle coverage is priced. A lower base rate with a smaller discount often beats a higher base rate with a larger discount.
Per-Vehicle Coverage Decisions That Move the Rate
Start with liability limits. Higher limits cost more, but the increase is smaller than most drivers expect, and it applies per policy, not per vehicle. If you're going to raise liability limits, do it once for the whole policy rather than trying to split limits by vehicle—most carriers don't allow that structure.
Collision and comprehensive are per-vehicle elections. The premium drops immediately for the vehicle where coverage is removed. Deductibles work the same way: you can carry a $500 deductible on the financed car and a $1,000 deductible on the paid-off car, or drop physical damage coverage entirely on vehicles where the annual collision premium exceeds 10 percent of the car's value.

Deductible Structure Across Multiple Vehicles
Deductibles are the amount you pay out of pocket before the carrier pays a collision or comprehensive claim. A $500 deductible costs more in annual premium than a $1,000 deductible, and that difference multiplies when you're covering three or four cars.
The decision framework: if you can cover a $1,000 repair without financial strain, a $1,000 deductible saves premium every year. If one vehicle in the household is older or driven less, raising its deductible or dropping collision entirely removes that vehicle's physical-damage premium from the policy. Households that keep collision on every car often do so out of habit rather than intentional choice, and the annual cost compounds across vehicles.
A common failure mode: a household raises the deductible on one vehicle to lower the premium, then adds a second vehicle with a low deductible and wonders why the combined rate didn't drop as much as expected. The new vehicle's low deductible adds back the premium the first vehicle's high deductible removed. Deductible decisions must be coordinated across the policy, not made in isolation per car.
Louisiana Uninsured Motorist Rate
11.7%
Approximately 11.7 percent of Louisiana motorists drive uninsured. Uninsured motorist coverage is optional in Louisiana but protects your household when an at-fault driver has no insurance. The coverage applies per policy, not per vehicle, and costs less than most drivers expect.

Comparing Carriers for Multi-Vehicle Policies
Rate structures vary significantly by carrier, and the carrier that offers the lowest rate for a single vehicle may not offer the lowest rate for a multi-vehicle household. Some carriers price aggressively for multi-car policies; others apply the discount uniformly but start from a higher base rate. Louisiana has 19 carriers writing standard and non-standard auto policies, and comparing quotes across several of them is the only way to identify which rate structure fits your household's vehicle mix.
When comparing, provide identical coverage specifications for each vehicle: the same liability limits, the same deductibles, the same optional coverages. If you vary coverage between quotes, you're comparing different products, not different carriers. Request quotes with and without collision on older vehicles so you can see the per-vehicle savings.
What to Do Right Now
Pull your current Louisiana policy declarations page and identify what coverage you carry on each vehicle: liability limits, collision and comprehensive elections, deductibles, and optional coverages like uninsured motorist or rental reimbursement. If any vehicle is worth less than ten times its annual collision premium, calculate whether dropping collision saves more than you'd lose in a total-loss scenario. If you're carrying a $500 deductible on every vehicle and can cover a $1,000 repair, request a quote with $1,000 deductibles across the policy and compare the annual savings. Then compare quotes from at least three carriers writing multi-vehicle Louisiana policies with identical coverage specifications. The combination of per-vehicle coverage adjustments and carrier comparison produces the largest rate reduction available to multi-car households.
