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.
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.
To calculate the added cost in purchasing comprehensive and/or collision coverage we looked at annual insurance quotes for a 30 year old male from New York across four different insurance companies, and the ten best-selling vehicles in the US. We look at the range of rates you could pay from basic liability to policy plans with comprehensive and collision coverage. Collision typically costs more than comprehensive, although some companies require you to carry both rather than just one. Comparing quotes across at least three companies can get you lower car insurance rates.
Financial experts often say it’s smart to drop collision when you drive an old car, then put your car insurance savings in a fund earmarked for emergency repairs or buying a new car. However, when you’re trying to decide when to drop collision coverage, the answer really comes down to your personal finances. “If you’re not absolutely sure that you could deal with paying for repairs or completely replacing your vehicle at a moment’s notice, or else going without a vehicle until you could save for a replacement, it’s best to err on the side of caution and pay the extra premium for collision coverage,” The Simple Dollar advises.

Collision insurance is a coverage that helps pay to repair or replace your car if it's damaged in an accident with another vehicle or object, such as a fence or a tree. If you're leasing or financing your car, collision coverage is typically required by the lender. If your car is paid off, collision is an optional coverage on your car insurance policy.
