Where do you find an online truck driver test?

Testing to secure a Commercial Driver License to drive a truck is not available online. Online practice tests, however, can be found at sites such as CDL Career Now and Test Prep Review. Testing for Commercial Driver Licenses is administered by each state's licensing or motor vehicle department.

To drive a truck commercially, a driver must pass the written CDL exam as well as a road test. General knowledge is required regarding trucks and roads, air brakes, loading and securing cargo, stopping ranges, and maximum weights. A clean driving record, no felony record, and a physical exam are also required.
