If you have a CDL license with “B” and “P” endorsement but no “S” endorsement, you need to take one written test which is section 10, school buses. Once you complete the test, come to Transportation and look at Transportation videos. You will need to sign up for five days (three hours each day) to prepare for your DPS road test. These five days are for actual practice driving and Transportation performance test. Once you complete your training and you are ready for the DPS road test, we will call the DPS office to schedule your driving test.
