The cheapest car insurance may not provide sufficient protection, so how much insurance should you buy? Bare-bones coverage may be a good choice if you have few assets or have an old car and don’t drive much. But if you have a home and investments, consider buying more insurance. If you don’t, you’re at risk for having your money and house taken to cover the cost of an accident. If you financed your car you will be required to get additional comprehensive and collision coverage.

Use our How Much Car Insurance Do You Need? tool to get a recommendation.


We recommend you buy more insurance than is required to legally drive a car in your state, especially if you have savings and assets. The more money you have, the more likely you are to be sued following a car accident should your insurance be insufficient to cover all the expenses. If your net worth is:

  • less than $50,000, choose at least 50/100/50
  • between $50,000 and $100,000, choose at least 100/300/100
  • more than $100,000, choose at least 250/500/100

If you’re leasing or financing your car, you must get coverage of 100/300/100 or higher.

Collision and comprehensive

Collision coverage pays for damage to your car after an accident that you cause. Comprehensive insurance pays to replace stolen cars and for damages from vandalism, flooding, hail, fire and animal strikes. If your car is:

  • less than 10 years old, you should strongly consider buying collision and comprehensive.
  • more than 10 years old, only buy collision and comprehensive if your car is worth $3,000 or more, if you couldn’t afford to replace your car if it’s wrecked, or if you just want more protection on your policy.

For drivers in Montana, collision costs an average of $540 yearly, comprehensive is $331, according to rate data. If you buy comp and collision, check our guide to choosing a deductible amount.

Medical coverage (MedPay)

Medical payments coverage can help pay for the medical or funeral expenses of covered drivers and passengers after an accident, regardless of fault, up to $25,000. In most states, including Texas, it’s an optional addition to your car insurance policy. MedPay does the following:

  • Covers you and your passengers’ medical expenses
  • Pays for expenses after health insurance limits are exceeded
  • Offers additional protection to insured drivers who are hit by a car while walking or biking

If you and your passengers:

  • Don’t have health insurance, or have a plan that doesn’t cover car accidents or has low limits, we recommend that you add medical coverage of at least $5,000 to your car insurance policy.
  • Do have health insurance, it’s still a good idea to have medical coverage if you want the best protection in your policy, as it can pay out after your health benefits are maxed out.

Gap insurance

If you don’t own your car outright and have an accident, gap insurance pays the difference between the cash value of your car and the current outstanding balance on your loan or lease.

  • If you’re financing your car, your car is less than one year old and you’ve put less than 20 percent down on it, you should buy gap insurance. If not, you don’t need gap insurance.
  • If you’re leasing your car, it’s a good idea to buy gap insurance if you aren’t already required to in your lease agreement.
  • If you own your car outright, you don’t need gap insurance.

Montana Car Insurance Laws

RoadsNumber of Fatal Accidents

The easiest and most popular means for drivers to comply with Montana’s financial responsibility law is by purchasing an auto insurance policy that meets the state required minimum limits. (Drivers can also post a surety bond or obtain a self-insurance certificate, but very few do.)

Most new cars are worth more than the state’s property damage liability minimum of $20,000, so you risk a personal lawsuit if you happen to hit something that just came off the showroom floor. We recommend you increase all your liability limits if you have substantial savings or a home to protect.

America’s autobahn? Nope. Montana has speed limits, and it puts points on your motor vehicle record for violating them. But the state doesn’t allow insurance companies to increase your premium for speeding convictions of less than 10 mph over the limit during the day and 5 mph over the limit at night.

Consequences for being an uninsured motorist: Penalties escalate in Montana the more times you are found driving without insurance. A first offense comes with a fine of at least $250 or up to 10 days in jail. A second offense fine starts at $350, same jail time option, but also the owner must surrender the vehicle’s registration and plates for up to 90 days.

A third offense results in a minimum fine of $500 and/or up to six months in jail and the surrender of license plates and registration for up to 180 days. A fourth or subsequent conviction comes with the same potential fine, jail time and registration/plates suspension as a third offense plus the driver’s license will be suspended until proof of insurance is provided.

Senior driver discount: State law mandates that Montana auto insurance providers offer drivers age 55 and older a reduction in premiums upon the successful completion of a highway traffic safety program that is approved by the Montana Department of Transportation. The discount given varies by insurer.
