Pennsylvania CDL permit test: what to expect
The written exam most people call the Pennsylvania CDL permit test is the general knowledge test, and passing it is what gets you a commercial learner's permit rather than the license itself. You need 80% to pass, a federal standard that is the same in every state. The number of questions is set by Pennsylvania, and our practice tests use the common 50-question format.
Once you hold the permit you have to keep it for at least 14 days before you are allowed to attempt the skills test, so it is worth sitting the written exam as early as you can. Practice below until you are clearing Pennsylvania's standard comfortably rather than scraping it.

5 Pennsylvania CDL Practice Questions and Answers
Here are 5 sample Pennsylvania general knowledge questions with the right answer and a quick explanation for each. Read through them, then take the quiz above to see how you do without looking.
1. If you are driving a 60-foot vehicle at 55 mph, what is your minimum safe following distance?
- A. 5 seconds
- B. 6 seconds
- C. 7 seconds (correct answer)
- D. 8 seconds
Why: The rule is 1 second per 10 feet of length (60 ft = 6 seconds). Because you are traveling over 40 mph, you add 1 additional second, making the required following distance 7 seconds.
2. How often should you inspect your tires when driving in very hot weather?
- A. Every 5 hours or 500 miles.
- B. Every 2 hours or 100 miles. (correct answer)
- C. Once a day before your trip.
- D. Every 4 hours or 200 miles.
Why: In very hot weather, tires should be inspected every 2 hours or 100 miles because air pressure increases with temperature, which can lead to tire failure.
3. When backing up, turning the steering wheel sharply can cause a tractor-trailer to do what?
- A. Straighten out automatically.
- B. Jackknife rapidly. (correct answer)
- C. Disengage the fifth wheel automatically.
- D. Lock the steering axle brakes.
Why: A tractor-trailer pivots at the kingpin. Turning the steering wheel too sharply or holding it too long while backing can force the vehicle into a severe jackknife very quickly.
4. What is the meaning of the acronym PASS when using a fire extinguisher?
- A. Pull, Aim, Squeeze, Sweep. (correct answer)
- B. Push, Accelerate, Stop, Secure.
- C. Point, Apply, Spray, Suppress.
- D. Pull, Activate, Shoot, Soak.
Why: PASS stands for Pull the pin, Aim at the base of the fire, Squeeze the handle, and Sweep from side to side. This is the standard method for effectively using a fire extinguisher.
5. If an oncoming driver fails to dim their high beams, where should you look to avoid being blinded?
- A. Directly at the oncoming headlights to gauge their distance
- B. At the right edge of your lane or the right edge of the road (correct answer)
- C. At the center line of the road
- D. Down at your dashboard until the vehicle passes
Why: To avoid glare from oncoming high beams, look toward the right side of the road and watch the right lane line or edge line to guide your steering.
