In Connecticut, the Class A CDL written test is available in Spanish, as well as English and several other languages.

This is because commercial driving requires the ability to communicate in English, both on the road and with law enforcement officers. Therefore, it is important for drivers to have a good understanding of English in order to operate a commercial vehicle safely and effectively.
