The Texas Department of Public Safety (DPS) has implemented a significant change to the state’s commercial driver licensing process, requiring all commercial driver license (CDL) and commercial learner permit (CLP) knowledge exams to be administered exclusively in English.

The new policy took effect June 1 and aligns Texas testing procedures with federal English language proficiency requirements established by the Federal Motor Carrier Safety Administration (FMCSA). State officials say the change is intended to help ensure commercial drivers possess the communication skills needed to safely operate large vehicles and comply with federal regulations.

Before the change, applicants could take CDL knowledge exams in either English or Spanish. However, the practical skills portion of the licensing process—including the pre-trip inspection, basic vehicle control exercises, and road test—has long been conducted only in English.

Under the updated rules, anyone scheduled to take CDL or CLP knowledge exams on or after June 1 must complete all written and automated testing in English. Interpreters are not permitted during the examination process.

To assist applicants preparing for the new requirements, DPS has made updated study materials available at no cost through its website. The agency is also offering the latest edition of the Texas Commercial Motor Vehicle Driver’s Handbook to help prospective drivers prepare for testing.

The department noted that English language proficiency evaluations will continue during routine commercial vehicle inspections, traffic stops, and weigh station checks. DPS troopers and other certified inspectors will assess drivers’ ability to meet federal communication standards while operating commercial vehicles.

Commercial drivers found unable to satisfy those requirements may be placed out of service until compliance issues are addressed.

According to DPS, the testing changes are part of broader efforts aimed at improving highway safety and ensuring commercial drivers can effectively communicate in situations involving law enforcement, emergency responders, and transportation officials.
