Sample Nebraska CDL Test Questions - General Knowledge

Question 1

A hazard ahead will require you to slow down. How should you warn following drivers?

  1. A Tap the brake pedal lightly to flash the brake lights
  2. B Stop in the traffic lane and begin directing traffic
  3. C Sound the horn continuously
  4. D Make a sudden lane change around the hazard

Correct answer: A – Tap the brake pedal lightly to flash the brake lights

A large commercial vehicle may block following drivers’ view of a hazard. Lightly tapping the brake pedal flashes the brake lights and warns them that you will need to slow. Four-way flashers are used when the vehicle is traveling very slowly or is stopped.

Question 2

Which three distances make up total stopping distance?

  1. A Perception distance, reaction distance, and braking distance
  2. B Observation distance, response distance, and slowing distance
  3. C Perception distance, steering distance, and reaction distance
  4. D Sight distance, following distance, and braking distance

Correct answer: A – Perception distance, reaction distance, and braking distance

Total stopping distance consists of perception, reaction, and braking distances. Perception distance is traveled while the driver recognizes a hazard, and reaction distance is traveled before braking begins. Braking distance covers the vehicle’s movement from brake application until it stops.

Question 3

Which statement about cargo weight limits in Nebraska is correct?

  1. A The maximum legal weight is safe under every driving condition
  2. B The shipper is solely responsible if the vehicle is overloaded
  3. C Applicable laws establish maximum gross and axle weights
  4. D A load never needs another inspection after the trip begins

Correct answer: C – Applicable laws establish maximum gross and axle weights

Applicable laws establish maximum wheel, axle, axle-group, and gross weights. The driver remains responsible for recognizing an overloaded or poorly balanced vehicle, even when someone else loaded it. A legal maximum weight may still be unsafe during severe weather or on mountainous roads.

Stat. § 60-6,294(1)–(3) — Vehicles; weight limit; further restrictions by Department of Transportation, when authorized; axle load; load limit on bridges; overloading; liability

Question 4

When may a driver operate a CMV after taking an over-the-counter cold medicine?

  1. A After reducing the labeled dose by half
  2. B Only when the medicine does not cause drowsiness or otherwise impair safe operation
  3. C Only during daylight hours
  4. D Whenever a dispatcher grants permission

Correct answer: B – Only when the medicine does not cause drowsiness or otherwise impair safe operation

Cold medicines and other over-the-counter drugs may cause drowsiness or otherwise interfere with safe driving. A driver may not operate while affected by any substance to a degree that prevents safe vehicle operation. A smaller dose, daylight, or dispatcher approval does not make impaired driving permissible.

Question 5

While driving a heavy CMV on a Nebraska off-ramp that curves downhill, what should you do?

  1. A Assume the posted ramp speed is safe for every vehicle
  2. B Reduce to a safe speed before entering the curve
  3. C Accelerate before reaching the curve
  4. D Wait until you are in the curve to downshift

Correct answer: B – Reduce to a safe speed before entering the curve

A downhill ramp makes it harder to reduce speed, and braking while turning can increase the risk of a skid or rollover. Ramp speeds that are suitable for automobiles may be too fast for large or heavily loaded vehicles. Enter the curved portion at a safe speed and in the proper gear.

Question 6

What is the safest response when another vehicle is following your CMV too closely?

  1. A Brake sharply to make the driver back away
  2. B Flash the taillights as a warning trick
  3. C Increase the space between your vehicle and the vehicle ahead
  4. D Wave the other driver around you

Correct answer: C – Increase the space between your vehicle and the vehicle ahead

Increase your following distance when you are being tailgated. More space ahead allows you to slow gradually and reduces the need for sudden speed or direction changes. Do not speed up, brake sharply, or use signaling tricks to discourage the tailgater.
