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.
Data was obtained from the Texas Department of Insurance for a thirty year old single male driver across 78 cities. He owns his car and uses it primarily for work purposes, averaging about 12,000 miles annually. Insurance policies include Texas’s minimum auto insurance liability requirements: $30,000 for bodily injury liability per person (up to $60,000 per accident), and $25,000 of property damage (30/60/25 coverage) liability insurance, 50/100/50, as well as 100/300/100. Car insurance costs are based on a 2011 Toyota Camry four-door sedan, with 2.5 liter/4 cylinder engine.
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.
