The auto insurance market in the U.S. is dominated by a few key players. In fact, the top ten auto insurance companies control more than 72% of the market. While the top ten insurance companies underwrite a large number of policies, they have very distinct characteristics. To help you choose the best insurance company for your situation, we created a list of the top ten largest auto insurance companies in the U.S. and discuss what makes each of them unique.

Uninsured / underinsured motorist (UM / UIM) covers costs associated with an accident involving uninsured or underinsured motorists, or hit and run drivers. You can’t control the coverage of other drivers on the road, but if you get in an accident with someone who doesn’t have insurance — or who has insufficient protection — you’ll be forced to deal with the costs yourself. We know it’s frustrating to have to pay for someone else’s negligence, but opting for UM / UIM coverage will be well worth it when you need it.
Car shows and meetings – The limited use provision of a classic car policy allows for travel to car shows and auto club meet-ups; however, this coverage may be restricted by some insurers. If this is the case, there are insurers that can provide specialized coverage for car shows and meetings. Before choosing a classic car insurer, it’s worth checking whether they have travel restrictions if you plan to take your car on regular, multi-day, high mileage drives.
The best way to find this out is to complete some research on your own. Look at some of the recent studies completed and read through them, then read as many online reviews as you can find. Also, make sure to shop around and compare rates among the handful of companies you feel comfortable with. The more you shop around and compare, the better off you’ll be.
Because most forms of insurance are regulated at the state level, state legislation influences car insurance premiums. For instance, in Michigan, a no-fault state, state law requires an unlimited amount of Personal Injury Protection coverage, a requirement that increases the cost of car insurance. Although each state legislates insurance differently, auto insurance prices may vary on a zip code-by-zip code basis. Below is an analysis of the cheapest and most expensive states for car insurance (from The Zebra's State of Insurance study).
For instance, a moving violation affects your driving record for three years in most states. Once you know it has been three years since your ticket, there’s no need to wait for your current auto policy to expire. You can immediately quote a new policy that will no longer charge you for that violation. The same goes for an at-fault accident, which will typically affect your rate for three to five years (but can vary by state and carrier). In addition, Progressive offers discounts for being ticket- and accident-free.
Companies do not have a standard rule as to what is considered high risk. If you have had an accident or moving violation the variance in premium will differ from company to company. You may have to get several quotes before finding the company that will work with a poor driving record. If you are diligent, then you should be able to find a rate you can live with.
All classic car insurers share a few vital elements. Primarily, they all have an "agreed value" stipulation which allows you to set how much you think your vehicle is worth in the event of a total loss. They also all provide pivotal comprehensive and collision insurance to protect your vehicle from anything that may damage it. There does exist however, several key differences. While the field of companies for classic cars is not as vast as it is for normal cars, some classic car insurers are better than others.
While most collectible automobile insurance policies are relatively similar, the way carriers classify different types of collectible vehicles, including some types they exclude coverage for, is important to understand. Although definitions, years and descriptions can vary from insurer to insurer and state to state, the most common collectible auto categories are below. We generally will use classic and collector car insurance interchangeably for the purposes of simplicity.
Of the biggest auto insurers in the U.S. - State Farm, GEICO, Allstate, Progressive and Farmers - State Farm ranks as the greatest overall. State Farm was rated 4/5 stars by customers and policyholders in a JD Power survey on companies shopping experience. State Farm is best known for its large agent network; they boast over 18,000 across the nation. It shouldn't be surprising then that State Farm gets 5/5 stars for how its agents interact with customers. As well, State Farm is great when it comes to offering discounts. If you go with State Farm you will have up to 15 discounts to be eligible for which can equal hundreds of dollars worth of savings.
In contrast, a Stated Value policy (sometimes called “stated amount” or “maximum limit of liability”) does not promise to pay the full vehicle value that’s indicated or “stated” on the policy. With regard to a covered total loss, you may receive less than that stated amount, because the insurer has the right to pay either your vehicle’s depreciated actual cash value OR the cost to replace your vehicle -- whichever is less. Also, many insurers that offer stated value policies (typically standard insurers) require periodic appraisals to affirm the insured amount, adding cost and inconvenience to the client.

J.D. Power ranks Farmers Auto Insurance better than most for claims satisfaction — an important endorsement, considering that on-time and fairly-sized claim payouts are the ultimate goal of insurance. Besides that, Farmers has a great coverage selection. A few options, like new car replacement and custom parts coverage, we didn’t see among all our top picks. We also like the company’s accident forgiveness program, which “will forgive one at-fault accident for every three years you drive without one.”
In April 2018, Northwest Arkansas News shared the story of a Siloam Springs woman who, after being hit by a city-owned tractor-trailer, found herself with medical bills in excess of $80,000. The city-owned vehicle carried Arkansas’s minimum 25/50/25 policy, which only provided $25,000 towards the woman’s medical bills; the woman carried $25,000 in uninsured/underinsured motorist insurance, which left $30,000 in medical bills she owed out of pocket. Because the tractor-trailer was a city vehicle, the woman was not able to sue for the remainder of her damages.
Sure, upgraded coverage means a higher monthly premium. But would you rather pay a bit extra each month, or wind up owing a lump sum of $30,000 out of pocket? The average American will file a collision insurance claim about every 18 years, according to insurance industry statistics. Hopefully, it’s nothing more than a fender bender, but if the worst should happen, you’ll appreciate being fully covered.
Customers aren’t very impressed by Liberty Mutual’s claims process or payouts. It’s ranked among “the rest” in J.D. Power’s survey, which falls at the bottom of the scale. It also earned a relatively low Consumer Reports score of 88 (or 23rd place out of 27 companies scored). Finally, Liberty Mutual didn’t quite meet the bar we set for financial stability. Its “A” from S&P Global and “A2” from Moody’s come up a little short of our requirements. These scores are still respectable — indicating an ability to pay out on claims — but mean that Liberty Mutual has a slightly poorer credit outlook in the event of a financial downturn.

Grundy wants you to enjoy your car, not keep track of mileage like some programs with limitations.  Therefore, we give you unlimited miles for pleasure driving and in collector car-oriented activities.  It is even OK if occasionally you drive your collector car to work to show it off to friends.  However, your collector car must not be used as a daily driver.  We require you and all licensed drivers in your household to have a modern car for everyday use.
When shopping for affordable car insurance quotes, come in with a good idea of your vehicle's value via Kelley Blue Book and NADA. If you determine your vehicle is worth more than $4,000 but you need to save money, consider raising your deductible. Because your car insurance deductible and premium are inversely related, you can lower your bill by raising your deductible. Looking at the chart below, you can see how your premium is affected by adjusting your deductible.
