Collision coverage is generally sold with a separate deductible. Even if you are at fault for the accident, your collision coverage will reimburse you for the costs of repairing your car, minus the deductible. If you're not at fault, your insurance company may try to recover the amount they paid you from the other driver’s insurance company and, if they are successful, you'll also be reimbursed for the deductible.
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.
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.
If your car is worth more than $3,000 and/or is less than 10 years old, we'd also suggest both collision and comprehensive coverage, too. Our estimates suggest drivers can buy comprehensive and collision insurance for an average of $600 to $700 per year (however, the cost may be higher for some cars), so you would spend $3,000 to $3,500 in premiums over five years. If your car is currently worth less than $3,000, you will have spent more on insurance than your car is worth. You can obtain the estimated value of your car from sites like Kelley Blue Book and Edmunds. Once you have both the value and a quote for coverage, you can determine whether collision insurance will be worth it.
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.
