Does Comprehensive mean you can drive any car?
Don't assume that because you have comprehensive car insurance you're covered to drive someone else's car. In fact, if you do get behind the wheel without checking that you're insured, you could be driving illegally.
Is comprehensive the same as full coverage?
The difference between full coverage and comprehensive insurance is that full coverage is a car insurance policy that includes both comprehensive and collision insurance along with the state's minimum requirements. Comprehensive insurance covers damage to a car from things other than accidents, like theft or fire.
