Auto insurance is financial protection, and not just for the investment you made when you bought your car. After a really serious accident, bills for damage and injuries can easily reach into hundreds of thousands of dollars. If you happen to cause such a wreck, the victims could sue you. In the worst case scenario, assets such as your savings and home could be seized.
One of the most common ways to lower your car insurance rates is by choosing a higher deductible. The deductible is the amount of money you must pay after an accident before your insurance kicks in. So, for example, if you are in an accident and there is $10,000 worth of damage done and your deductible is $1,000, you pay the $1,000 and your car insurance company pays $9,000. A higher deductible means less risk for your insurance company and lower rates for you. However, it also means that you need to have that much money on hand in case of an accident. If you go for a $2,000 deductible and don’t have $2,000 available after an accident, you won’t be able to get the repairs you need.
Comprehensive car insurance covers damages from an "act of God," or events that are not caused by a car driving into something else. An "act of God" can include things like damage from a heavy tree branch falling on your car. Since you have no control over when or why a tree branch would fall on your car, this kind of accident would be covered under your comprehensive policy.
