Practice questions are available to study online for a CDL, Commercial Driver's License, exam but the written and road tests must be taken in person. These skills tests are typically offered at the nearest state Department of Motor Vehicles office in the state that the driver resides.
Eligible drivers must have a current license for the state in which they are testing for a CDL. They must also have the required documents for their state’s DMV. These include proof of age, driving record, training, medical condition and residency for the driver. Once these items are approved by the DMV, the driver can take the written exam.
A score of 80 percent or better on the written portion of the CDL exam qualifies the driver to take the CDL skills tests on the road. However, the driver must have training prior to taking the skills test. He needs to show proof of attending a truck driving school, having held a CDL previously or have a CDL instruction permit for at least 30 days prior to the skills tests.
The driver provides proof of insurance and a registered vehicle for the driving test. The driver notifies the DMV of the endorsements he is attempting to gain and pays the necessary fees at the office. Once all these items are completed successfully, the driver obtains a CDL.
