If you already have any other type of insurance such as health, homeowners, disability or life insurance, you can see if your carrier will give you a discount for adding your car insurance policy with your insurance portfolio. Many companies carry this type of multi-line policy discount, but you will need to ask if it is available. In addition, if you have more than one vehicle whether it is a boat, motorcycle, RV or trailer, you may be able to get a discount on your insurance if you carry multiple vehicles under the same policy.
