One of the most common ways to lower your car insurance rates is by choosing a higher deductible. The deductible is the amount of money you must pay after an accident before your insurance kicks in. So, for example, if you are in an accident and there is $10,000 worth of damage done and your deductible is $1,000, you pay the $1,000 and your car insurance company pays $9,000. A higher deductible means less risk for your insurance company and lower rates for you. However, it also means that you need to have that much money on hand in case of an accident. If you go for a $2,000 deductible and don’t have $2,000 available after an accident, you won’t be able to get the repairs you need.
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.
For some, the best coverage is the cheapest car insurance policy that makes them able to legally drive on the road. For others, the best coverage is the type that covers the full cost of repairs on your vehicle when you file a claim. The only way to be certain you are fully protected is to purchase both comprehensive coverage and collision coverage. Each coverage has its own job to do.
