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.
One way to do this is to call the insurance company and see what the hold time is and what the service is like when you wait to speak to a representative about a general inquiry. If the hold time is 3 hours and they don’t seem like an accommodating group, you’re probably not going to want to deal with them after you just lost your house and file a claim.
