well I base my statement by the following which was listed as driver qualifications by the DOT and can be found in the state booklet as well:

A driver can certify that, during the 2-year period immediately prior to applying for a CDL he/she:

Has not had more than one license;
Has not had any license suspended, revoked, or canceled;
Has not had any convictions in any type of motor vehicle for major disqualifying offenses;
Has not had more than one conviction for any type of motor vehicle for serious traffic violations;
Has not had any violation of State or local law relating to motor vehicle traffic control arising in connection with any traffic accident, and has no record of an accident in which he/she was at fault.
