How can you get the best car insurance rates?

Besides comparing rates from multiple companies, every driver should take advantage of the following steps to reduce the cost of their insurance policy:

  • Ask your insurer about discounts. All major insurance companies offer discounts to reward customers who engage in safe driving practices or who are loyal. You can receive discounts for installing anti-theft devices, bundling your car insurance with the company's home plan or taking a defensive driving course.
  • Regularly re-evaluate your coverage needs. Your individual coverage needs will change over time. For instance, if you're driving significantly less these days, you should see if a pay-per-mile program would be better suited for your lifestyle. If you don't expect to use your car anytime soon, but don't want lapses in coverage, you might save money by having a minimum-coverage policy.
  • Contact your insurer for an updated quote if your driving profile changes. Your car insurance cost is influenced by multiple factors, including your age, credit score and ZIP code. Have any of these changed? See if your insurer will quote you a lower rate compared to what you have now.

Get cheaper rates by taking advantage of discounts

When it comes to finding cheap auto insurance, there are things you cannot control easily or at all, like your age, gender or vehicle. That’s why taking advantage of all the discounts at your disposal is so important. If you think the following discounts could apply to you, make sure to ask your insurance company if they offer them.

  • Low-mileage discounts are available through many car insurance companies. Often, this discount applies to people who drive their vehicle 8,000 miles per year or less, but the exact number varies between insurers. Alternatively, you can look into pay-per-mile or telematics-based car insurance programs.
  • Bundling multiple policies with one company, like your home and auto or renters and auto insurance policies, can save you hundreds of dollars every year. Bundling discounts tend to be around 5% to 20%.
  • Defensive driver courses can lower your rates, sometimes lowering specific parts of your policy by around 10%, according to our survey of courses. Over a few years, the cost of the course usually pays for itself.
