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.
Financial experts often say it’s smart to drop collision when you drive an old car, then put your car insurance savings in a fund earmarked for emergency repairs or buying a new car. However, when you’re trying to decide when to drop collision coverage, the answer really comes down to your personal finances. “If you’re not absolutely sure that you could deal with paying for repairs or completely replacing your vehicle at a moment’s notice, or else going without a vehicle until you could save for a replacement, it’s best to err on the side of caution and pay the extra premium for collision coverage,” The Simple Dollar advises.
Collision insurance is a coverage that helps pay to repair or replace your car if it's damaged in an accident with another vehicle or object, such as a fence or a tree. If you're leasing or financing your car, collision coverage is typically required by the lender. If your car is paid off, collision is an optional coverage on your car insurance policy.
