Review all 20 questions with answers
  1. Your delivery truck must reverse beneath an unfamiliar loading canopy. What should you do before moving?

    Correct answer: Get out and check the entire backing path

    Walk the intended path and check side, overhead and nearby hazards. A view from the cab alone may miss an obstruction.

  2. A coworker offers to guide your truck backward. What should you settle before the maneuver begins?

    Correct answer: Hand signals, including a clear stop signal

    Both people should understand the signals before backing. The helper should remain where the driver can see them.

  3. You can reposition a truck to back around a corner toward either side. Which setup generally gives you the better view?

    Correct answer: Back toward the driver's side

    Driver-side backing improves the driver's view of the rear through the side window. Repositioning first can be worth the added time.

  4. In an unsynchronized manual truck, you stay in neutral too long during an upshift and the next gear will not engage. What is the safer response?

    Correct answer: Match engine speed in neutral, then try again

    Do not force a missed shift. Return to neutral, release the clutch, match engine speed to road speed and try again; the technique requires practice.

  5. You checked the mirrors, then signaled a lane change. Why check the mirrors again before moving over?

    Correct answer: A vehicle may have entered your blind spot

    Traffic positions can change after the first check. Recheck after signaling and continue checking as the lane change begins and finishes.

  6. A car looks small and far away in your truck's convex mirror. What should you allow for?

    Correct answer: It may be closer than it appears

    Convex mirrors widen the view but make objects appear smaller and farther away. Do not judge a passing gap as though the image were a direct view.

  7. While checking traffic around your truck, which mirror-scanning habit best keeps the road ahead under observation?

    Correct answer: Take brief looks, then return to the road

    Use brief mirror checks and return attention to the road ahead. Long mirror fixation lets the truck travel without monitoring developing hazards in front.

  8. A driver behind your slow truck gestures for you to signal when passing will be safe. What is the sound practice?

    Correct answer: Do not direct the other driver to pass

    Do not take over another driver's passing decision. A reassuring wave can be misunderstood or overlook a hazard the other driver will encounter.

  9. Your loaded truck needs to slow substantially for a tight turn, and a car is following. How should you make the slowdown predictable?

    Correct answer: Signal early and slow gradually

    Early signaling and gradual braking give following drivers time to recognize that a large vehicle needs a slow turn.

  10. A driver estimates stopping space using only the distance traveled after the brakes begin working. What has been left out?

    Correct answer: Distance used to recognize and react to danger

    The truck keeps moving while the driver perceives the danger and reacts. Total stopping space includes those distances as well as braking distance.

  11. On a cold morning the road looks clear, but you are approaching a bridge. Why should you be especially alert there?

    Correct answer: The bridge can freeze before nearby pavement

    Bridge surfaces can freeze sooner than nearby roads. Clear pavement before the bridge does not establish traction on the bridge itself.

  12. Your truck begins hydroplaning on standing water. You have room ahead and are not about to collide. How should you begin reducing speed?

    Correct answer: Ease off the accelerator; avoid braking

    Reduce power so the truck slows and the tires can regain road contact. Braking while hydroplaning can worsen loss of control; in a manual vehicle, the manual also calls for disengaging the clutch.

  13. You are approaching a curve in a tall, loaded truck. A car ahead takes it at the posted speed. What should determine your approach?

    Correct answer: Slow before the curve to a safe speed for your truck

    A posted curve speed may still be too fast for a truck with a high center of gravity. Reduce speed before turning rather than combining hard braking with the curve.

  14. A car follows your truck too closely. Why is increasing your gap from the vehicle ahead a useful response?

    Correct answer: It gives you more room to slow gradually

    More space ahead reduces the need for sudden slowing or steering. Avoid speeding up or using brake-light tricks against a tailgater.

    Source: New Jersey CDL Manual, March 2025 cover; Section 2, July 2017 footer; printed 2-17 (physical 35); 2.7.2 Space Behind, Dealing with Tailgaters Safely. ↗

  15. A car has stayed beside your truck for a long stretch. When traffic permits, which positioning habit best preserves side space?

    Correct answer: Find an open position away from the car

    Traveling beside another vehicle leaves little escape room if either driver moves laterally. Seek separation rather than remaining boxed in.

    Source: New Jersey CDL Manual, March 2025 cover; Section 2, July 2017 footer; printed 2-17, 2-18 (physical 35, 36); 2.7.3 Space to the Sides, Traveling Next to Others. ↗

  16. An empty box truck is leaving a tunnel into strong crosswinds. Which precaution is most appropriate?

    Correct answer: Avoid emerging beside another vehicle if possible

    Crosswinds can be especially difficult at tunnel exits, and lighter vehicles are more affected. Extra side space reduces the consequences of a gust.

  17. Your cargo van passed under a low structure when fully loaded. It is now empty. What should you assume about the return trip?

    Correct answer: Clearance must be checked again

    Unloading can raise a van's body. A safe passage while loaded is not proof that the empty vehicle will fit under the same structure.

  18. After loading, your truck must cross a drainage dip in an unpaved yard. What clearance issue deserves a fresh check?

    Correct answer: The underside or ends may drag

    A heavy load can reduce the space beneath the vehicle. Drainage dips may cause its underside or ends to strike the ground.

    Source: New Jersey CDL Manual, March 2025 cover; Section 2, July 2017 footer; printed 2-18 (physical 36); 2.7.5 Space Below. ↗

  19. You are entering a road with a heavily loaded truck. Why might a gap you would accept in a car be inadequate?

    Correct answer: The truck needs more time and space to accelerate

    Truck size and slower acceleration increase the space needed to enter or cross traffic. A heavier load calls for a larger margin.

    Source: New Jersey CDL Manual, March 2025 cover; Section 2, July 2017 footer; printed 2-19 (physical 37); 2.7.7 Space Needed to Cross or Enter Traffic. ↗

  20. A high-sided truck travels beside a sharp pavement-edge drop near tree limbs. What hazard can occur if its wheels drop off?

    Correct answer: The truck can tilt and strike an overhead object

    An edge drop can tilt the truck toward roadside objects. It also complicates steering back across the edge, so recognize and avoid the hazard early.
