Bodily injury coverage is written with two limits: the first applies to each person; the second is related to each accident. As an example, minimum recommended coverage levels are usually $100,000/$300,000, which translates to policy limits of $100,000 per person in an accident and $300,000 total per incident. Required coverage levels vary by state, but can be as low as $10,000/$20,000, which is hardly sufficient for a serious accident.
Comprehensive insurance is a coverage that helps pay to replace or repair your vehicle if it's stolen or damaged in an incident that's not a collision. Comprehensive typically covers damage from fire, vandalism or falling objects (like a tree or hail). If you're financing or leasing your car, your lender likely requires comprehensive coverage. If you own your vehicle outright, it's an optional coverage on your car insurance policy.
