Erie is the cheapest insurance company, and arguably the most reliable insurance company as well. They score points by allowing customers to start their quote online, which we personally found to be a streamlined and fast process. Erie also scored the highest marks from the number of policies they offer. Erie offers pet coverage, free accident forgiveness, free vanishing deductibles, roadside assistance, and many more, essentially giving its customers a degree of flexibility not even found amongst the largest insurers. Customers of Erie may also be eligible for its Rate Lock program. This is a unique program where customers won't see their rates increase except for three reasons: you move to a different area, add or remove someone from your policy, or add or subtract a car. Lastly, despite its smaller size, Erie offers the same types of discounts larger national insurers provide such as bundling, anti-lock brakes, anti-theft, young driver and senior driver among others.
9 Auto/Home Multi-policy Discount: A discount will apply to the total policy premium for those insured with both home and private passenger automobile insurance with MetLife Auto & Home. The percentage amount of the discount may vary by state. The Auto/Home Multi-policy Discount is not available to auto policies where the insured's homeowners insurance is a renter's policy, and is not available on the homeowners policy, if the auto policy is written by Metropolitan General Insurance Company or at a nonstandard rate level. 
Receive 5% off your auto policy premium when you already purchased qualifying life insurance or annuity products written by Metropolitan Life Insurance Company or an affiliated company domiciled in the United States. Not available in all states.

If you find yourself away from the wheel more times than not, a pay-per mile auto insurance company like Metromile may be the best company to go with. Metromile is one of the first companies in the U.S. where a bulk of a driver's premium is determined by how much they drive. How much is too much? We found that generally for Metromile to be a good deal, drivers should only drive 7,500 miles or less per year. The biggest downsides to Metromile is a mediocre record of claims handling, in addition to the company only being available in seven states: CA, IL, NJ, OR, PA, VA, WA.

Results: Once I submitted my information, the site produced one quote, along with six links to other insurance companies. “View my quote” buttons next to each quote took me to the beginning of the insurance website’s own quoting tool, making it clear that these were strictly hypothetical rates. Everquote provided a blurb of marketing text about two of the companies and no helpful information whatsoever to guide my decision.
The moral of our analysis is pretty straightforward: the only way to find the absolute best rate for you is to shop around frequently. By frequently, we are referring to any time your driving profile changes. Whether that's because of the driving factors we listed above but also if you had a birthday, if you moved, changed vehicles, got married, or even bought a house. Because you’re not locked into a contract with your insurance company, if you find a better rate elsewhere you are able to cancel your insurance and move on to a cheaper company. Use our insurance calculator here to see which company best fits your driving profile.

A company that specializes in the most basic coverage options may have the cheapest auto insurance rates. However, they may also lack some customer service benefits of more established companies. These benefits may include 24 hour customer assistance and claims tracking. Consumers should always be aware of these trade-offs as they make their decision.
How it works: Compare’s shopping process asked me to enter the same general information that other auto comparison websites did. Entering the information was fairly straightforward. Most of the fields were drop-down menus or pre-filled based on information I had submitted on previous pages. The questions were detailed, including some about my current policy limits that required retrieving my insurance documents to answer. I did like that Compare asked if I was willing to accept paperless documents and/or e-signing
The hardest part is finding out which auto insurance company will give you the most value for your money while providing the reliable coverage you need as a driver. You’ll never know if you’re getting cheap car insurance unless you compare it with other major insurance companies. To avoid overpaying for your current coverage, start comparing quotes today at Compare.com.
You will need to know the make, model, year and VIN (Vehicle Identification Number). An online quote form may be able to pre-fill a large portion of this information by using the VIN found on the dashboard under the windshield or your state’s vehicle registration paper work. Sometimes an insurance form may ask you to differentiate between the different models and security features.
