Just because you have received a notice that your insurance may be canceled, do not panic. You may have forgotten to pay a bill, or it could have been delayed in arriving, or any of a number of possibilities. Take the time to read through the notice you received, and then take appropriate action as detailed in the notice.
The two most common reasons for your auto insurance to be canceled are either failure to pay the premium when it was due or excessive claims or risks against the policy. If you receive a notice from the insurance company which mentions intent to cancel but does not give you a reason, contact the number provided. If the problem is simply a missed bill, you will probably be able to pay the bill and bring the account up to good standing without any other problems.
If your driver's license has been suspended, your insurance may have been canceled as well. Many insurance companies have clauses that exclude insuring drivers who are guilty of certain offenses, such as drinking and driving. If you have violated one those clauses, the insurance company had the option of terminating your coverage, usually at the end of the current billing cycle.
If neither of these options seem likely, then you will need to contact the insurance company. The company may have had an error that sent out such notices to all customers in a specific zip code, all without any intention of cancelling policies. Another possibility could be that your insurance company is no longer going to offer coverage in your particular area. If this is the case, they may provide you with suggested sources of where to look in order to maintain your existence coverage with a new insurance writer.
