While an “insured vehicle” may include a friend or neighbor’s vehicle or a rental car, if the vehicle was available for regular use, it might be excluded. A “replacement” vehicle will probably be covered, but in some cases only under circumstances where the insured’s vehicle cannot be operated for some specific reason, such as a repair. Coverage might not follow anyone if the insured is driving a vehicle other than a “private passenger vehicle not owned and listed on the insured’s policy.” There really is no such thing as a standard auto policy anymore and coverage for non-owned autos will be different under some policies and non-existent under others.
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.
To help you figure out if you should purchase collision coverage, you should estimate the approximate value of your vehicle. While there are a number of online resources that can help with this, including Kelley Blue Book, we recommend you speak with a State Farm® agent. In addition to helping you determine the value of your vehicle, our agents can tell you how much extra you'd pay to add collision coverage.
Once you know the approximate value of your car and the cost to carry collision coverage, then you can make an informed decision about purchasing that coverage. Many people find that it's a good idea to cover newer cars, but as cars get older, their values decrease, and you might consider omitting or dropping this coverage to save money on your auto 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.
