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