State of Ok Bus Driver Training
Athletic Office

The written section is given first and includes multiple tests, depending on the type of commercial vehicle you plan to drive. They are given by the examiner, and you must score at least 80% on the knowledge tests in order to qualify for a CDL in Oklahoma.

In our Applying for a New CDL section, we highlighted the various endorsements you could have on your CDL.

There are separate knowledge tests given for these endorsements, including:

  • General Knowledge: taken by all applicants.
  • Passenger Transport: required if you plan to drive a passenger bus.
  • Air Brakes: required if your vehicle has air brakes you will be required to take this test.
  • Combination Vehicles: taken if you plan to drive Combination Vehicles.
  • Hazardous Material: required of those drivers who will transport Hazardous Materials.
  • Tanker Test: must be administered to those drivers who wish to haul liquid in bulk form.
  • Doubles/Triples: required if you wish to drive Doubles or Triples.

There is also a "fail fee" for tests administered by the State of Oklahoma. Each time you take a test and fail, you will be charged $4. However, this fee will not be collected until you pass the test. Once you pass, the "fail fees" will be added to your final fee total, as determined by your examiner.

Road Test

You will be required to provide the vehicle for this test. If you have attended a truck driver school or have undergone training through your company or prospective company, they will, in most cases, provide the appropriate vehicle for your road test. Ask your instructor or supervisor for details on this.

The first part of the on-Road Test will be a pre-trip inspection of your vehicle's air brake system. You will be asked to inspect the air brake components and explain to the Examiner what you are looking at and why.

The Commercial Driver's Manual does not mention a pre-trip general safety inspection, but it is always a good idea to complete a basic visual check of tires, lights and electrical coupling.

Make sure that everything is secured and no tools, rocks or other items are placed where they might fall off when the truck is in motion. Double check the mud flaps to make sure they are securely bolted in place. Inspect any hitches or connections and take a quick look inside the fuel tanks. Make sure there are no puddles or leaks under the truck and finally, check your mirrors and make sure they are clean and clear.
