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.
In a best-case scenario, you’ll never have to use your car insurance. After all, making a claim on your auto insurance means you’ve suffered some sort of loss, and no one wants that. However, going through life without ever having a fender bender or other damage to your car is unlikely. In some cases, you’ll be making a car insurance claim after a harrowing experience, like a serious accident. After going through something like that, you want to be sure your insurance company isn’t going to make things worse.
The best companies will also have several supplemental coverage options, or endorsements, that you can add to your homeowners policy. Endorsements can vary, as some provide higher coverage limits for certain types of personal property like jewelry or fine furs; or they can provide supplemental coverage for risks — like water backups, floods, or earthquakes — not covered by home insurance.
Collision coverage is limited to the actual cash value of the vehicle, and requires a deductible, which is the amount you'll need to pay before receiving benefits. Higher deductibles lower your premium but increase the amount you must pay out of your own pocket if a loss occurs. Ask yourself how much you would be willing to pay on short notice in order to save on your premium, or talk to your agent.
While there are a couple of benefits of collision insurance, the main one is that you can file a claim and receive reimbursement regardless of who was at fault. Collision claims usually get processed faster than property damage claims because the insurance company does not have to spend time investigating who was at-fault. Another benefit is that you only deal with your own insurance company, rather than another insurer with less incentive to pay for your claim. Collision insurance can also be used toward your rental car in most cases, which can spare you from having to buy rental car insurance.
