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.
Let's use the aftermath of a major storm to illustrate the differences between collision and comprehensive. Within that storm, let's consider two hypothetical events: First, a heavy telephone pole was blown down and fell on your truck, or second, you swerved to avoid a falling tree and wound up crashing into a guardrail. In the first event, you couldn't control when or why a tree fell on your car. This kind of accident would get reimbursed under your comprehensive policy. In the second situation, you were driving the car and ultimately swerved into the guardrail. This makes it a collision, and collision insurance pays for the damages.
The cost of insurance is on the rise: the price for auto insurance rose 3.6% between 2011 and 2012, and 3.1% for homeowners and renter’s insurance, according to the Insurance Information Institute. In fact, auto liability insurance premiums alone have been increasing by 2.8% annually for the past three years. This makes choosing the right coverage and provider all the more crucial to save money without sacrificing important aspects of coverage.
