Sample Minnesota CDL Test Questions - General Knowledge

Question 1

Which list includes everything counted in a combination vehicle’s actual gross weight?

  1. A The power unit and trailer, without cargo
  2. B The trailer and cargo only
  3. C The power unit, towed unit or units, and cargo
  4. D The driver and cargo only

Correct answer: C – The power unit, towed unit or units, and cargo

Actual combination weight includes the power unit, the towed unit or units, and the load being carried. Minnesota law describes the actual-weight portion of gross vehicle weight for a truck-tractor and semitrailer combination as the unloaded combination plus the load. Do not confuse actual weight with GCWR, which is a rating determined under a separate definition.

Question 2

Battery fluid, whether acid or alkali, belongs to which hazardous-material class?

  1. A Class 6.1 poison
  2. B Class 3 flammable liquid
  3. C Minor fire hazard
  4. D Class 8 corrosive material

Correct answer: D – Class 8 corrosive material

The federal Hazardous Materials Table lists both battery fluid, acid and battery fluid, alkali as Class 8 materials. Class 8 identifies corrosive substances. “Minor fire hazard” is not a hazardous-material class, and battery fluid is not classified as a Class 3 flammable liquid merely because it is a liquid.

Source: Minnesota Commercial Driver’s License Manual (March 2025) — § 2.23, “Hazardous Materials Rules for All Commercial Drivers”, 49 CFR § 172.101 – Purpose and Use of the Hazardous Materials Table (entries “Battery fluid, acid” and “Battery fluid, alkali”)

Question 3

You are approaching a downhill, curving off-ramp in a heavily loaded commercial vehicle. What should you do?

  1. A Enter at the posted ramp speed without considering the vehicle’s weight
  2. B Reduce to a safe speed before reaching the curve
  3. C Accelerate before entering the curve
  4. D Wait until you are in the curve to downshift and slow

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

The Minnesota CDL manual advises entering the curved portion of an off-ramp slowly enough to maintain control. A ramp speed that works for an automobile may not be safe for a large or heavily loaded vehicle. Because a downgrade makes speed reduction harder, slow before the curve rather than relying on heavy braking while turning.

Question 4

Which listed vehicle fire may require large quantities of water for cooling?

  1. A A tire fire
  2. B A gasoline fire
  3. C An electrical fire
  4. D An unidentified hazardous-material fire

Correct answer: A – A tire fire

A burning tire must be cooled, and a large amount of water may be necessary. Water should not be used on electrical fires because of shock risk or on gasoline fires because it can spread the flames. If the correct method is uncertain, especially with hazardous materials, wait for trained firefighters.

Question 5

A Class C fire rating applies to which type of fire?

  1. A A fire involving energized electrical equipment
  2. B A fire involving wood, paper, or cloth only
  3. C A fire involving gasoline or oil only
  4. D A fire involving combustible metals

Correct answer: A – A fire involving energized electrical equipment

Class C identifies fires involving energized electrical equipment. These fires require a nonconducting agent, such as carbon dioxide or an appropriate dry chemical. A B:C extinguisher is rated for both flammable-liquid and electrical fires, while an A:B:C extinguisher also covers ordinary combustibles such as wood, paper, and cloth.

Question 6

Which statement correctly distinguishes GCW from GCWR?

  1. A GCW is a manufacturer’s rating; GCWR is the vehicle’s actual weight
  2. B GCW applies only to the power unit; GCWR applies only to the trailer
  3. C GCW is the actual combined weight; GCWR is the combination’s rated or determined weight value
  4. D GCW and GCWR are interchangeable terms

Correct answer: C – GCW is the actual combined weight; GCWR is the combination’s rated or determined weight value

GCW is the actual combined weight of the power unit, towed units, and their loads. The Minnesota CDL manual defines GCWR using the manufacturer’s displayed value or, when necessary, the highest applicable combination of the units’ GVWRs and actual weights. A rating is not necessarily the same as the combination’s present scale weight.
