Any car insurance comparison tool you look at should have your state’s minimum car insurance requirements pre-loaded into its options. States requiring PIP or medpay are generally referred to as “no-fault” states, meaning that when injuries occur, each driver in a crash makes a claim with their own insurance company to pay for them. Beyond the PIP or medpay limit, the at-fault driver’s liability insurance kicks in to cover the rest.
There are two types of insurance comparison websites: quote comparison sites and lead generation sites. Auto quote comparison websites present users with rates based on information submitted during the shopping experience. You can then decide which quote to pursue, and the data you entered is transferred to the agent or company website, greatly shortening the purchasing process. These sites do not sell your information to insurance carriers or agencies.
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.
Like most auto insurance companies, they advertise low rates (“15 minutes could save you 15% or more on your car insurance”). But what else? According to JD Power’s 2018 U.S. Insurance Shopping Study, low and competitive prices are becoming the norm, so most companies are in “aggressive customer courtship mode.” Geico’s response to this seems to be their very popular mobile app.
Drivers looking for low car insurance costs in San Jose should start with quotes from GEICO, Nationwide and Century National. The mean annual premium from these three insurers was $1,163 based on our data, which is about 49% cheaper than the overall average in San Jose. Citywide, the cost of car insurance is about $1,731 a year, which places the Capital of Silicon Valley at the 93rd cheapest spot in our survey of Californian cities.
Homeowners aren't the only ones who need insurance. No matter where you live, having insurance protection helps you keep your finances intact by avoiding losses from theft, fire or other events that damage or destroy your personal property. And if you cause an accident that damages the apartment or condo itself, insurance can provide you with important protection in those cases, too.

State legislators set limits on how much a company can increase your rates after a crash. Our hypothetical accident resulted in only $2,000 worth of damage. That caused average annual rates to spike by $1,000 or more in some states, while others jumped by far less. One thing’s for sure: Your rates will definitely increase after an at-fault accident, so be sure to compare car insurance rates if you have one on record.


Unlike quote comparison sites, lead generation sites simply sell your information to their advertising partners—typically insurance companies. These sites are not built to provide you with personalized quotes and are not much help when trying to compare car insurance rates. Avoid these sites unless you’re eager to receive tons of cold calls from insurance phone banks and desperate agents.
Allstate thrives when it comes to discounts for young drivers and students. The company’s Smart Student Discount will apply to anyone under the age of 25 who is either a full-time student with good grades, has completed the teenSMART driver education program, or attends a school within 100 miles of their home. Young drivers are typically the most expensive to insure; this unique discount can alleviate some of those costs.
If you have an anti-theft device, Progressive offers a discount for that too. The company also offers pet injury coverage — which is included with collision and comes standard in most states. However, Progressive’s scores across the board were only average, and we couldn’t justify recommending it over our top picks. Also, its mobile app ratings average out to just under 3 out of 5 stars.
