Sample Minnesota CDL Test Questions - General Knowledge

Question 1

Which procedure is used to check hydraulic brake-pedal pressure with the vehicle secured and the transmission in Park?

  1. A While moving, pump three times and hold for five seconds
  2. B While moving, pump five times and hold for three seconds
  3. C While stopped, pump three times and hold firmly for five seconds
  4. D While stopped, pump five times and hold for three seconds

Correct answer: C – While stopped, pump three times and hold firmly for five seconds

The Minnesota CDL manual’s general hydraulic-brake procedure is to place the transmission in Park, pump the pedal three times, and hold it down for five seconds. The pedal should remain firm and should not continue moving downward. Hydraulic systems vary, so the vehicle manufacturer’s specified procedure must also be followed.

Question 2

Which group of factors should guide your choice of speed on a long, steep downgrade?

  1. A Following distance, perception time, and lane width
  2. B Reaction time, vehicle length, and traffic volume
  3. C Vehicle and cargo weight, grade length and steepness, road conditions, and weather
  4. D Vehicle color, cargo type, and the number of mirrors

Correct answer: C – Vehicle and cargo weight, grade length and steepness, road conditions, and weather

A safe downgrade speed depends on the total weight of the vehicle and cargo, the length and steepness of the grade, road conditions, and weather. Heavier vehicles and steeper or longer grades require more speed control. Warning signs and any posted maximum safe speed must also be observed.

Question 3

To remain prepared for a possible tire failure, how should you normally grip the steering wheel?

  1. A Firmly with both hands
  2. B Firmly with only the dominant hand
  3. C Loosely with both hands
  4. D Loosely with one hand

Correct answer: A – Firmly with both hands

Keep a firm grip on the steering wheel with both hands. If a front tire fails, the resulting force can twist the wheel and cause a loss of directional control. A two-handed grip gives the driver the best chance to keep the commercial vehicle under control.

Question 4

After the engine starts, what should the coolant-temperature gauge do?

  1. A Immediately rise to its maximum reading
  2. B Begin a gradual rise toward the normal operating range
  3. C Remain at the cold reading throughout the trip
  4. D Fluctuate sharply between hot and cold

Correct answer: B – Begin a gradual rise toward the normal operating range

After startup, the coolant-temperature gauge should gradually rise toward the normal operating range as the engine warms. Oil pressure should reach its normal range much sooner, generally within seconds. Monitor the coolant gauge during operation and investigate an abnormally high reading before it leads to engine damage or fire.

Question 5

Which items belong in a commercial vehicle’s pre-trip inspection?

  1. A Cargo and its securement devices
  2. B Vehicle lights for proper operation and cleanliness
  3. C Both A and B
  4. D Neither A nor B

Correct answer: C – Both A and B

Before driving, verify that cargo is balanced and properly secured and that its securement devices are suitable. The walk-around inspection also includes checking that required lights operate and cleaning lights, reflectors, and glass as needed. Both checks help ensure the vehicle can be operated safely.

Question 6

An article is longer than 5 feet but no longer than 10 feet and is not blocked against forward movement. What is the minimum number of tiedowns required?

  1. A 1
  2. B 2
  3. C 3
  4. D 4

Correct answer: B – 2

Federal cargo-securement rules require at least two tiedowns for an unblocked article longer than 5 feet but no longer than 10 feet, regardless of weight. Different minimums apply to shorter articles based on weight and to longer articles based on length. Blocking or immobilizing an article against forward movement can also change the calculation.
