Sample Pennsylvania CDL Test Questions - General Knowledge

Question 1

What is the primary safety benefit of an antilock braking system?

  1. A It permits higher speeds and shorter following distances
  2. B It prevents every type of skid
  3. C It always reduces stopping distance
  4. D It helps prevent wheel lockup and maintain control during hard braking

Correct answer: D – It helps prevent wheel lockup and maintain control during hard braking

ABS adjusts brake pressure when it detects that wheels are about to lock. This helps the driver maintain control during hard braking and may preserve the ability to steer around an obstacle. ABS does not necessarily shorten stopping distance, increase normal braking capacity, or prevent every possible skid.

Question 2

What handling problem can result from placing too much weight on the steering axle?

  1. A Hard steering
  2. B Unusually light steering
  3. C Easier braking
  4. D Improved drive-wheel traction

Correct answer: A – Hard steering

Poor cargo balance can make a commercial vehicle unsafe to handle. Excessive weight on the steering axle can make steering difficult and may damage the steering axle or its tires. Cargo should be distributed to keep axle weights within limits and provide safe steering and traction.

Question 3

While operating an ordinary commercial vehicle in Pennsylvania, when may you interrupt a funeral procession?

  1. A When carrying an urgent shipment
  2. B When your traffic signal is green
  3. C When there appears to be a safe gap
  4. D Never; only an emergency vehicle may interrupt it

Correct answer: D – Never; only an emergency vehicle may interrupt it

Pennsylvania law states that a funeral procession must not be interrupted by any vehicle other than an emergency vehicle. A green signal, an open gap, or an urgent delivery does not create an exception for an ordinary commercial vehicle. Drivers in the procession must still yield to emergency vehicles using the required warning signals.

Question 4

After stopping at an all-way stop, which vehicle must you yield to before entering the intersection?

  1. A A vehicle already in the intersection
  2. B A vehicle waiting on your left, even if it arrived later
  3. C A vehicle that is farther from the intersection than you are
  4. D No vehicle, because stopping gives you the right-of-way

Correct answer: A – A vehicle already in the intersection

Pennsylvania law requires a driver at a stop sign to yield to a vehicle already in the intersection or approaching closely enough to create a hazard. Enter only when it is safe. If two vehicles approach or enter from different roads at approximately the same time, the driver on the left must yield to the driver on the right.

Source: 75 Pa.C.S. § 3323(b) — Stop Signs and Yield Signs., 75 Pa.C.S. § 3321(a) — Vehicle Approaching or Entering Intersection.

Question 5

Which habits can help a commercial driver remain alert and fit to drive?

  1. A Get enough sleep and schedule trips for safer hours
  2. B Exercise regularly and choose healthy food
  3. C Avoid medicines that impair driving and receive regular medical checkups
  4. D All of these answers are correct

Correct answer: D – All of these answers are correct

Pennsylvania’s CDL manual recommends adequate sleep, safe trip scheduling, regular exercise, healthy eating, caution with medications, and regular medical care. Some prescription and over-the-counter medicines can cause drowsiness or otherwise affect safe driving. Drivers should check warning labels and follow medical advice about whether a medicine is compatible with driving.

Source: Pennsylvania Commercial Driver’s Manual — § 2.23.1, “Be Ready to Drive.”

Question 6

Which of the following should be recognized as a potential traffic hazard?

  1. A A delivery truck with blocked visibility
  2. B A stopped bus with passengers nearby
  3. C A disabled vehicle with people working beside it
  4. D All of these answers are correct

Correct answer: D – All of these answers are correct

Each situation provides clues that someone may enter the roadway or make an unexpected movement. Delivery-truck cargo or doors may block visibility, passengers may cross near a stopped bus, and people working around disabled vehicles may be close to traffic. Recognizing these clues early gives a commercial driver more time to respond safely.
