Do you know what to look for on your auto policy's declarations, or information page?
First off, verify your personal information is correct. Be sure to notify your agent if this information changes.
Secondly, make sure that your vehicle information is correct - year, make, model, and VIN - your rate is heavily based on this information and if it is incorrect and you file a claim, you will have some problems settling.
Next, if you have a loan on your vehicle, the lienholder will most likely require that their info be listed on the policy so make sure this is correct.
Remember that the higher your deductible, the lower your premium but this means if something happens you have to pay more out of pocket.
Review your coverages and if you have questions or concerns, talk to your agent.
