Virginia is one state that allow drivers to take the Commercial Driver's License, or CDL, test in Spanish. The state even provides accompanying study materials in Spanish.
New Jersey is another state that provides drivers with the option of taking a Spanish version of the computer-based CDL test. However, the CDL manual that is provided online is in English only. To know if a specific state offers the CDL test and study material in Spanish, check with the Department of Motor Vehicles or DMV website for that specific state. That site should provide instructions as to how to take the CDL test and what materials to study in preparation for it.
