What Full Coverage Means for Montana Households
You carry Montana's minimum liability — $25,000 per person, $50,000 per accident, $20,000 property damage — on two or three vehicles. Now you're weighing whether to add collision and comprehensive to one, some, or all of them. The term "full coverage" is shorthand for a liability policy with collision and comprehensive added. It protects your own vehicles, not just the other driver's.
Montana does not mandate collision or comprehensive. The state requires only liability coverage to register and drive legally. Full coverage is a choice, typically driven by lender requirements on financed vehicles, the value of the car itself, or the household's ability to replace a totaled vehicle out of pocket. When you add it to a multi-vehicle policy, every car with full coverage re-rates the policy independently — the second car's collision premium reflects that car's value, age, and your household's claim history, not a flat percentage of the first car's rate.

$25,000 / $50,000 / $20,000
Montana requires $25,000 bodily injury per person, $50,000 per accident, and $20,000 property damage. These minimums cover damage you cause to others. They do not cover your own vehicle — that requires collision and comprehensive.

Collision and Comprehensive: What They Cover
Collision pays to repair or replace your vehicle after a crash with another car or object, regardless of fault. You back into a pole: collision covers your car. Another driver hits you and has no insurance: collision covers your car while uninsured motorist property damage pursues the at-fault driver. Collision applies per vehicle — if you add it to two cars on your policy, each has its own deductible and coverage limit.
Comprehensive covers non-collision damage: theft, vandalism, hail, fire, hitting an animal, glass breakage. Montana's vehicle theft rate in 2024 was 165.5 per 100,000 population. Comprehensive also applies per vehicle. A hailstorm damages two cars on your policy: you file two comprehensive claims, each subject to its own deductible.
Both coverages require a deductible — typically $500 or $1,000 per vehicle. Choose a $500 deductible and your out-of-pocket cost per claim is lower, but your premium is higher. Choose $1,000 and the premium drops, but you pay more when you file. The deductible applies per claim, per vehicle. Two cars damaged in the same incident = two deductibles.
Adding full coverage to a second or third vehicle re-rates the entire policy based on each car's value and risk profile, not as a flat percentage add-on.
How Full Coverage Changes a Multi-Vehicle Policy
Start with two vehicles on a Montana liability-only policy. You finance Vehicle A and the lender requires collision and comprehensive. You add full coverage to Vehicle A with a $500 deductible. The carrier calculates collision and comprehensive premiums based on Vehicle A's value, your ZIP code, your household's claim history, and the deductible. Vehicle B remains liability-only.
Six months later you refinance Vehicle B and that lender also requires full coverage. You add collision and comprehensive to Vehicle B with a $1,000 deductible. The carrier now calculates a separate collision and comprehensive premium for Vehicle B based on its lower value, the higher deductible, and the same household risk factors. Vehicle B's full-coverage cost is lower than Vehicle A's because the truck is worth less and the deductible is higher, but the total policy premium has increased by the full cost of Vehicle B's collision and comprehensive — there is no automatic discount for adding coverage to a second vehicle.

Lender Requirements and Household Coverage Decisions
Montana law does not require collision or comprehensive. Lenders do. Any vehicle with an active loan or lease carries a lender clause requiring full coverage until the loan is paid off. The lender is named on the policy as loss payee. If the car is totaled, the carrier pays the lender first, up to the loan balance, then pays you any remaining amount up to the vehicle's actual cash value.
Once the loan is paid off, the lender requirement disappears. You can drop collision and comprehensive and carry liability only. Many households keep full coverage on paid-off vehicles if the car's value justifies the premium — typically when the vehicle is worth more than ten times the annual collision and comprehensive cost.
When you own multiple vehicles outright, you can mix coverage levels. Keep full coverage on the newer, higher-value car. Carry liability only on the older, lower-value car. The policy allows different coverage on each vehicle. The multi-car discount applies to the entire policy regardless of which vehicles carry full coverage.
Montana Uninsured Motorist Rate
7.2%
In 2023, 7.2% of Montana motorists were uninsured. Collision coverage protects your vehicle when an uninsured driver hits you, while your carrier pursues the at-fault driver through uninsured motorist property damage or subrogation.

Deductible Strategy Across Multiple Vehicles
Each vehicle on your policy can carry a different deductible. Vehicle A with a $500 collision deductible. Vehicle B with a $1,000 collision deductible. Vehicle C liability-only. This structure is common when Vehicle A is the primary household car — driven daily, higher annual mileage, higher collision risk — and Vehicle B is a second car driven occasionally or by a less-experienced driver.
Raising the deductible lowers the premium but increases your out-of-pocket cost per claim. A household that can cover a $1,000 repair without financial strain typically chooses the $1,000 deductible and banks the premium savings. A household that cannot cover $1,000 on short notice chooses the $500 deductible and pays the higher premium for lower claim-time exposure. The deductible applies per vehicle, per incident. If two cars on your policy are damaged in separate incidents within the same month, you pay two deductibles.
Comparing Full Coverage Across Montana Carriers
Montana's carrier roster includes Allstate, Farmers, Geico, Liberty Mutual, National General, Progressive, Root, State Farm, The General, Travelers, and USAA. All write collision and comprehensive coverage. Rates vary by carrier based on each company's claims experience in your ZIP code, their underwriting model, and the discounts they apply to multi-vehicle policies. One carrier may price Vehicle A's full coverage lower while another prices Vehicle B's full coverage lower. Comparing quotes across carriers for the entire household policy — all vehicles, all coverages — surfaces the lowest total premium.
Request quotes with identical coverage limits and deductibles across carriers. If you compare a $500 deductible quote from one carrier against a $1,000 deductible quote from another, the rate difference reflects the deductible, not the carrier's pricing. Lock the variables: same liability limits, same collision and comprehensive deductibles, same vehicles, same drivers. The resulting quotes are comparable.
Next Step: Compare Full Coverage Quotes for Your Household
You now understand what full coverage adds to Montana's minimum liability, how collision and comprehensive apply per vehicle, and how deductibles and lender requirements shape the decision. The next step is comparing quotes from multiple carriers for your household's specific vehicles and coverage needs. Carriers price multi-vehicle full coverage differently. One may offer a lower rate for your newer car while another prices your older car more competitively. Enter your household's vehicles, choose your deductibles, and compare the total policy premium across Montana carriers writing your ZIP code.
