The key difference in collision vs. comprehensive coverage is that, to a certain extent, the element of the car driver's control. As we have stated before, collision insurance will typically 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," that are typically out of your control when driving. These can include such events as a spooked deer, a heavy hailstorm, or a carjacking.
Policies typically use vague language when referring to acts of terrorism, but they are generally insured by the comprehensive portion of your policy. For example, if there is an act of terror and you need to make a claim on your car, that can only be made if you have comprehensive coverage. Since some circumstances are out of our control, comprehensive insurance is certainly important to have in your policy.
Even if the open-enrollment period has passed for signing up for insurance via one of the exchanges, you might still be able to purchase subsidized insurance if you've had a qualifying life event. Qualifying events include moving to a new state, change in income, change in family, loss of coverage and others. You may even be able to apply simply because you did not understand that open-enrollment ended or you did not understand the health care law. If your income qualifies you for subsidized health care, you'll want to purchase through your state exchange.

The above is meant as general information and as general policy descriptions to help you understand the different types of coverages. These descriptions do not refer to any specific contract of insurance and they do not modify any definitions, exclusions or any other provision expressly stated in any contracts of insurance. We encourage you to speak to your insurance representative and to read your policy contract to fully understand your coverages.
