Cdl Learners Permit

Testing for the commercial driver learner permit

Oct. 15, 2018
The first step in obtaining a CDL: the learner's permit.

I haven’t studied for a learner’s permit in 20 years. 

Back when I first went to school to get my driver's license, I remember furiously highlighting the paper manuals from the driving school instructor, making sure to note the questions “you’ll certainly see on the written test.” 

Nowadays though, they’ve got smartphone apps and downloadable PDFs you can use as study aids. Having everything accessible online and at your fingertips can be both a blessing and a curse.

And thank goodness, since there’s a lot more information to know. The trucking industry is federally regulated, but drivers test for and receive a state-issued commercial driver's license. But, every state has similar exams to test for the learner permit. To obtain a learner permit, especially for the purposes of the WCTC class and for driving a Class 8 tractor-trailer in the state of Wisconsin, I needed to take three tests: General Knowledge, Air Brakes and Combination. 

Note: There are some variances from state-to-state when it comes to these tests. All require a general knowledge test, and a combination test. But, some may allow an air brakes restriction on a commercial driver's license. 

General Knowledge (50 questions).This exam covers the gamut when it comes to running a commercial vehicle, including safety and communication, road signs, hours of service, road and user hazards, and more.

Some sample questions include:

What is the gross vehicle weight (GVW)?

  • The total weight that includes the vehicle, towed vehicles, and the load
  • The total weight of a single vehicle and its load (correct answer)
  • A vehicle's maximum weight rating, specified by its manufacturer
  • All of the above

How far ahead should drivers look while driving on a highway?

  • 10 to 12 seconds
  • 5 to 10 seconds
  • 12 to 15 seconds (correct answer)
  • 7 to 12 seconds

What action should you take before driving while drowsy?

  • Pull off the road and get some sleep. (correct answer)
  • Open your vehicle windows for some fresh air.
  • Drink energy drinks.
  • Drink a cup of coffee.

Air Brakes (25 questions). This talks about the three separate (but really, connected) braking systems on a combination vehicle - the emergency brakes, the parking brakes and the service brakes. All are managed and maintained through the air braking system of the truck. If you've ever sat in the cab, you're likely familiar with the yellow (tractor) and red (trailer) buttons on the dash. In order to move, they need to be pushed in. 

Combination (20 questions). If you plan to drive more than a straight truck, or bobtail (aka, just the tractor), you're going to need to take the combination test. Essentially, this test covers aspects of coupling and uncoupling the tractor and trailer. 

You need at least an 80 percent to pass for each exam, and you can take each test up to five times, limited to once per day.

In addition to these tests, you can add separate endorsements for the following: Hazmat, Doubles and Triples, and Tankers. While I didn't test for these for my learner permit, I'm able to add them at anytime after receiving my CDL. 

Also, speaking of restrictions, you can have a restriction placed on your CDL to not drive manual transmissions. (e.g. only automated manuals or full automatics.)

But really, if I'm going to learn how to drive a truck, I should learn how to do it right. And, now that I've got that learner's permit testing out of the way, I'm ready to hit the road.
