[Gone in 60]

In the U.S., minimum requirements that all drivers must carry are determined state-by-state. In California, the minimum liability coverages are:
$15,000 for injury/death to one person.
$30,000 for injury/death to more than one person.
$5,000 for damage to property

As far as what these coverages cost, it depends on the insurance company, and factors such as:
Driver age and driving record
Location of vehicle
Type of vehicle (age, engine size, etc)

There are a ton of other factors which are determined by each insurance company.
