Beyond basic auto insurance

In addition to having enough liability protection, there are some other coverages you should consider:

Collision: Pays for damage to your car resulting from a collision with another car, an object or as a result of flipping over. It also covers damage caused by potholes. 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 are not at fault, your insurance company may try to recover the amount they paid out from the other driver’s insurance company though a process called subrogation. If the company is successful, you will be reimbursed for the deductible.

Comprehensive: Reimburses you for loss due to theft or damage caused by something other than a collision with another car or object, such as fire, falling objects, missiles, explosion, earthquake, windstorm, hail, flood, vandalism, riot, or contact with animals such as birds or deer. Comprehensive insurance will also reimburse you if your windshield is cracked or shattered; some companies may waive the deductible on the glass portion of this coverage.

Uninsured and Underinsured Motorist Coverage: Reimburses you, a member of your family, or a designated driver if one of you is hit by an uninsured or hit-and-run driver. Underinsured motorist coverage comes into play when an at-fault driver has insufficient insurance to pay for your total loss. These coverages are required in 19 states, but available in all. It is important to purchase the same amount of coverage for uninsured/underinsured motorists as you have for liability to others.
