DO I HAVE TO PASS ANY EXAMS TO GET A MARYLAND CDL?

Yes . . . You will have to pass written exams and skills exams. Just how many exams you will have to take and pass will depend upon the type(s) of commercial vehicles you will be driving and what type of "cargo" you will be transporting.

WHAT ARE THE MARYLAND CDL WRITTEN EXAMS?

The "written" exams consist of the knowledge portion of your Maryland CDL exams. There are seven different written exams. Which ones you will be required to take and pass depends upon the type of commercial vehicle that you will be driving. A description of these written exams follows . . .

  • Basic Vehicle Control Test . . . You will be tested on your basic skills in controlling the vehicle . . . including moving your vehicle forward, backward, and turning within a defined area. You will be scored on how well you stay within the exercise boundaries and how many pull-ups you make.
