Of our top auto insurers, State Farm has the fewest discounts. You won’t find any price breaks for young or elderly drivers, for being a loyal customer, nor for having a new car. Most of its discounts are safety related, like if you have airbags, anti-lock brakes, or enroll in a safe driving program. However, State Farm’s lack of discounts doesn’t mean your quote will be more expensive — just that you’ll have fewer opportunities to lower it.
Providers can also offer sub-divisions of auto repair insurance. There is standard repair insurance which covers the wear and tear of vehicles, and naturally occurring breakdowns. Some companies will only offer mechanical breakdown insurance, which only covers repairs necessary when breakable parts need to be fixed or replaced. These parts include transmissions, oil pumps, pistons, timing gears, flywheels, valves, axles and joints. 
Watch out for GEICO especially when changing coverages. I have learned the hard way that you can’t trust them to get your changes correct. I was just hit in the rear while stopped at a stop sign. I am trying to go through the collision coverage I am supposed to have only to have GEICO tell me that I removed this coverage a few months ago. The fact of the matter is I did not remove this coverage and never would have done that or agreed to that. Trying to reason with them has been an exercise in futility so far with a supervisor trying to put the onus on me for the problem. I am currently awaiting their final position on their review of this matter, but whatever the outcome I now know I cannot relie on them to get things right and I will always have to check on them. The mistakes they make hurt you, not them.
I was with Liberty Mutual for about 15 years and was very satisfied with their prices and service, although I never filed a claim. When I retired and moved from California to Florida, my auto rate went up a ridiculous amount, to almost $10,000 a year even though I had no accidents and one minor moving violation in the last ten years. On top of that, Liberty Mutual screwed up my umbrella policy and told me it was “unenforceable,” whatever that means, but I had to pay for the policy anyway up to the time I canceled and switched to Progressive, which cost about one third the cost of Liberty Mutual for an identical policy. Even good companies change over time.
When the premium is not mandated by the government, it is usually derived from the calculations of an actuary, based on statistical data. The premium can vary depending on many factors that are believed to affect the expected cost of future claims. Those factors can include the car characteristics, the coverage selected (deductible, limit, covered perils), the profile of the driver (age, gender, driving history) and the usage of the car (commute to work or not, predicted annual distance driven).
If liability insurance DOES NOT follow the driver, that suggests that one can NEVER skip the liability coverage offered by rental car companies. However it seems the generally accepted wisdom is that if you have your own car insurance, you need not buy the rental car liability insurance. So it’s either not as simple as you say or millions of people are going uninsured. Also, generally damage to the car, damage to another car, and loss of personal property are covered by many premium credit cards.
I used to have Farmers insurance until I got in an accident. Even though I had a local insurance agent, because I had to file my claim after hours, I had to contact a generic claims call center. Then, since I initiated the claim using the 1-800 number, I had to complete the rest of the process that way. At that point I was asking myself why I was paying a premium to have a local agent when he was doing nothing to help me. After the whole experience, I decided to shop around and ended up choosing Progressive. They had much better prices and since it no longer mattered to me to have a local agent, I signed up. I've had nothing but a positive experience with Progressive so far.
Police forces have the power to seize vehicles that do not have the necessary insurance in place, until the owner of the vehicle pays the fine and signs a new insurance policy. Driving without the necessary insurance for that vehicle is an offence that will be prosecuted by the police and will receive penalty. Same provision is applied when the vehicle is standing on a public road.
The regulations for vehicle insurance differ with each of the 50 US states and other territories, with each U.S. state having its own mandatory minimum coverage requirements (see separate main article). Each of the 50 U.S. states and the District of Columbia requires drivers to have insurance coverage for both bodily injury and property damage, but the minimum amount of coverage required by law varies by state. For example, minimum bodily injury liability coverage requirements range from $30,000 in Arizona to $100,000 in Alaska and Maine, while minimum property damage liability requirements range from $5,000 to $25,000 in most states.
When it comes to supplemental coverage, Travelers is hard to beat. It consistently met our marks for what we considered “the essentials” and it offers unique coverage, too. That includes accident forgiveness, GAP insurance, and special coverage for drivers employed by ridesharing operations like Uber and Lyft (though this add-on is currently only available in Colorado and Illinois).
Widespread use of the motor car began after the First World War in urban areas. Cars were relatively fast and dangerous by that stage, yet there was still no compulsory form of car insurance anywhere in the world. This meant that injured victims would seldom get any compensation in an accident, and drivers often faced considerable costs for damage to their car and property.
