How to get the cheapest car insurance in Great Falls

Full-coverage car insurance costs $186 per month in Great Falls, on average. However, you can find lower premiums if you know how to look. The tips below can help you reduce your car insurance rates:

• Compare car insurance quotes. Even if you like the first quote you get, it’s always a good idea to shop around. You may find cheaper rates for the same coverage from another insurer since every insurer weighs rating factors differently.

• Bundle insurance policies with one company. Bundling your car insurance with a homeowners or renters policy is more convenient for you, and many insurers offer multi-policy discounts for people who do.

• Look for car insurance discounts. When you get a car insurance quote, don’t rely only on the company’s agents to tell you what discounts you might be eligible for. Check out the insurer’s discount page and have an idea of which ones could help you save money on your policy.

• Adjust your coverage. Your car insurance policy shouldn’t be a “set it and forget it” situation. Reducing your coverage limits or raising your deductible could help you lower your premiums. Check with your insurance agent periodically to see if you have the appropriate amount of coverage.

Cheapest liability-only car insurance in Great Falls

Liability car insurance is the least amount of coverage you must carry to drive in the state of Montana legally. It covers costs related to bodily injury and property damage another driver suffers due to a car accident where you’re at fault. Liability coverage doesn’t pay for your vehicle or car accident-related medical bills, however.

State Farm offers the cheapest liability-only car insurance in Great Falls, at $42 per month. The table below shows the lowest liability-only insurance quotes in Great Falls.

Cheapest full-coverage car insurance in Great Falls

While liability-only car insurance covers other drivers’ vehicle damage and medical bills, full coverage protects you, your vehicle, and your finances. It’s ideal if your car is newer or you couldn’t afford to pay for a replacement if it was declared a total loss after a car accident. If you financed your car, your lender will likely require you to carry full coverage until you pay off the loan.

State Farm also offers the cheapest full-coverage car insurance, with a monthly rate of $98. The following table shows the cheapest full-coverage car insurance quotes in Great Falls.

Cheapest car insurance for drivers with an incident

Maintaining a clean driving record and practicing safe driving habits are great ways to keep your car insurance premiums low. Incidents do happen, however. When incidents such as speeding tickets, at-fault accidents, and driving under the influence happen, there’s a good chance your premium will increase.

But insurance companies don’t have a universal premium increase rate. The severity of the rate increase following an incident varies by insurer. The following sections will show you how various incidents can affect your car insurance rates in Great Falls.

Average cost of car insurance by age

Age is one of the main factors car insurance companies consider when determining rates. Teen drivers have the highest rates due to their lack of experience behind the wheel. Insurers reward drivers with lower premiums as they gain more experience, usually around age 35.

Unfortunately, insurers often increase drivers’ rates when they reach age 70, as older drivers are more likely to get into a car accident because of visual impairments and physical or cognitive decline.

The table below demonstrates how car insurance rates can change in Great Falls depending on a driver’s age.
