A commercial driver training school may advertise by whatever method it sees fit with the following exceptions:

1. The address of a telephone-answering service, when it is not the same as the principal place of business of the school, shall not be shown in any medium of advertising or telephone directory. Nor shall any telephone directory listing or yellow page advertisement show a telephone number for a school unless it also shows a valid address, including the city, for the principal place of business of the school.
   
   
2. No advertisement shall indicate in any way that a school can or will issue or guarantee the issuance of a driver license, or imply that preferential or advantageous treatment from the Division can be obtained.
   
   
3. A school may state in an advertisement that it has been approved and licensed by the Division.
