Our products help to prepare you to be able to pass the required CDL Tests. The actual CDL written tests must be taken in-person and with proper identification, at the state office under the authority and audit of government personnel. Our CDL training program is totally online and does not include any training in an actual vehicle. After receiving your CLP (commercial license permit), you will likely need to get some behind-the-wheel experience to be able to pass the three-part CDL skills tests. You may choose to get this experience through a friend, relative, employer or truck driving school. The actual CDL three-part skills tests will be given by either a state examiner or by a atate approved independant examiner. Depending upon the location; the CDL test vehicle will be provided by the examiner, or will be the responsibility of the applicant (a qualified CDL holder must be in the vehicle until your CDL is issued). The entire amount paid to us is strictly for the CDL Test Prep Program materials purchased on this website. YOU are responsible for additional CDL fees as established under State and/or Federal law and rules, third party testers, medical examiners, finger printing, background checks, truck rental fees, etc., as may be applicable.
