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.
Med Pay and bodily injury insurance are two other types of coverage that usually follow the person, not the car. Med Pay coverage pays for any injuries that an insured or his passengers may incur in an accident, regardless of who is at fault. Such coverage usually follows the driver. It is based on people, not the vehicle. In fact, such coverage sometimes covers the insured when he is walking or biking. This coverage also usually follows the driver when he rents a car, because the rental vehicle is a substitute for the insured’s own vehicle. However, Med Pay coverage sometimes follows the car. If the passengers in a vehicle don’t have coverage of their own, Med Pay and PIP coverage can extend to their injuries.
Comprehensive car insurance covers damages from an "act of God," or events that are not caused by a car driving into something else. An "act of God" can include things like damage from a heavy tree branch falling on your car. Since you have no control over when or why a tree branch would fall on your car, this kind of accident would be covered under your comprehensive policy.
When an insured allows other drivers to drive his vehicle, then, and only then, does the question of whether insurance follows the car or the vehicle become even awkwardly relevant. The right question to be asking is not whether insurance follows the car or the driver, but whether or not other drivers will be covered by the insured’s auto insurance.
Collision and comprehensive insurance are two optional types of auto insurance where your insurer pays for repairs to your vehicle. While there are other optional auto insurance coverages, liability, comprehensive, and collision are three of the most common. These coverages work hand-in-hand to repair or replace most of the damages to your car. It's important to know the difference, and make sure you're adequately covered.
