While the above is the lowest amount of insurance coverage you can have, you should consider adding more if you have more to lose. For example, we typically advise drivers to match their liability coverage to what they have in total assets. If you own a house in one of the most expensive zip codes in California, Atherton, and have sizable savings and investment accounts, we'd recommend you increase your liability limits and consider adding umbrella coverage on top. On the other hand, if you're a first-year student at UCLA, you may be fine with liability limits that are closer to the minimum.

If you happen to live in one of those states and are over the age of 45, you're likely going to see lower premiums than with other insurance companies. In our tests we looked at policies for single non-smokers in five different places. We found the premium rates were lower across the board than many other companies we tested, particularly for seniors. 
The cheapest car insurance, period, will likely carry the minimum coverage required in your state. In most states, this is liability insurance only, which covers property damage and medical bills for others due to accidents you cause.
