How to get the cheapest car insurance in Longmont

A variety of factors affect the rate you pay for car insurance. While some of them are outside your control, you can do some things to land the cheapest rates when you’re shopping for insurance:

• Shop around. It’s tempting to sign up for a policy with the first insurer you get a quote from or from the insurer you’ve always used. However, you may be able to get cheaper rates by shopping around and comparing rates from multiple insurers.

• Take advantage of discounts. You can lower your insurance premiums with discounts, including those for paying your premiums up front, being a good driver, having certain vehicle safety features, and more. Always ask your insurer what discounts you may qualify for.

• Bundle your home and auto policies. Most insurance companies offer a discount when you bundle your auto insurance with your other insurance products, such as homeowners insurance or renters insurance. You may even be able to save by bundling your auto and life insurance.

• Reduce your coverage. The more coverage types you have and the higher your auto insurance coverage limits, the higher your premiums will be. You can save by reducing your coverage — just don’t adopt limits below your needs.

• Increase your deductible. There’s an inverse correlation between your premiums and your deductible, which is the amount you’ll pay out of pocket for a claim. You can save on your premiums by increasing your deductible, even slightly.

Car insurance requirements in Colorado

Colorado law requires all drivers to carry minimum liability coverage, which includes both bodily injury and property damage coverage. Colorado’s minimum coverage requirements are comparable to most other states.

Colorado offers the option to self-insure for anyone with more than 25 registered vehicles. To qualify, someone must apply for a certificate of self-insurance from the state’s insurance commissioner. However, this won’t apply to most individual drivers.
