While availability can be limited, midsize insurers may beat cheap auto insurance prices from larger companies. Plus, according to a 2022 J.D. Power auto insurance shopping study, customers are often satisfied with these companies.

Follow these additional tips to get cheap auto insurance rates:

1. Ask for discounts. There could be savings from car insurance discounts you’re not taking advantage of. For instance, maybe you now work from home and are driving less frequently than when you bought your policy. Mention that and you might get a low-mileage discount.

2. Cash in on major life changes. Certain life events could translate to cheaper car insurance, so shop for quotes whenever something major changes in your life. For instance, many companies offer a lower rate for married couples or domestic partners. Or perhaps you moved to a suburb with lower accident and crime rates. Even if you moved to a more expensive area for car insurance, shopping around can help you get cheaper coverage.

3. Revisit quotes after your driving record improves. Shop for cheap car insurance quotes online three to five years after any accidents, tickets or moving violations. They may have dropped off your driving record.

The type of car you drive also affects how much you pay for auto insurance. Check out NerdWallet’s analysis of the cheapest cars to insure to see if your vehicle made the list.
