Let's use the aftermath of Superstorm Sandy as an example to illustrate the differences between collision and comprehensive. Within that storm, let's consider two events that might have happened: 1) a heavy tree branch fell on your car, or 2) you swerved to avoid a falling tree branch and wound up crashing into a tree. In the first event, you had no control over when or why a tree branch would fall 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 tree, which makes it a collision, and collision insurance therefore pays for the damages. Events like the hypothetical ones stated above are why it's important to differentiate between the two types of coverage.
Collision Insurance is an optional coverage that will pay for the cost of repairs up to a total loss, in which case Liberty Mutual will give you the cash value of the vehicle. Including it on your policy requires the purchase of comprehensive coverage. While there are similarities between collision coverage and comprehensive coverage, here are the details of both:
1 In Texas, the Auto Program is underwritten by Southern County Mutual Insurance Company through Hartford Fire General Agency. Hartford Fire Insurance Company and its affiliates are not financially responsible for insurance products underwritten and issued by Southern County Mutual Insurance Company. The Home Program is underwritten by Trumbull Insurance Company.
The main difference between collision and comprehensive coverage comes down to the question of what the driver controls. Collision insurance will cover events within a motorist's control or when another vehicle collides with your car. Comprehensive coverage generally falls under "acts of God or nature," or things that are typically out of your control when driving. These can include events such as a spooked deer, a heavy hailstorm, or a carjacking.
