Sample Minnesota CDL Test Questions - General Knowledge

Question 1

Except for a brief operational necessity, a vehicle carrying Division 1.1, 1.2, or 1.3 explosives must not be parked within 300 feet of which location?

  1. A A bridge or tunnel
  2. B A place where people congregate
  3. C An open fire
  4. D All of these locations

Correct answer: D – All of these locations

Federal hazardous-materials rules prohibit parking such a vehicle within 300 feet of a bridge, tunnel, dwelling, or place where people work, congregate, or assemble, except during brief operational necessities when no practical alternative exists. A vehicle containing hazardous materials also must not be parked within 300 feet of an open fire.

Question 2

When scanning the road ahead, which two broad categories should receive primary attention?

  1. A Traffic and roadway conditions
  2. B Passenger vehicles and traffic lights only
  3. C Disabled vehicles and roadside objects only
  4. D Curves and potholes only

Correct answer: A – Traffic and roadway conditions

Watch traffic for vehicles entering the highway, moving into your lane, turning, or slowing. Also scan roadway conditions for curves, lane changes, surface hazards, work zones, and other conditions that could affect speed or position. Looking far enough ahead gives you time to respond smoothly.

Question 3

Which group correctly identifies three major cargo responsibilities of a commercial driver?

  1. A Cargo dimensions, delivery schedule, and fuel quantity
  2. B Cargo inspection, proper weight balance, and securement
  3. C Opening sealed cargo, setting freight prices, and choosing the customer
  4. D Recording the seal number, selecting the route, and inspecting the shipper’s dock

Correct answer: B – Cargo inspection, proper weight balance, and securement

Drivers must inspect cargo, recognize overloads or poor weight distribution, and know that the load is properly secured. Federal rules require cargo to be properly distributed and secured and generally require inspections during transportation. The inspection requirements do not apply when a sealed vehicle must not be opened or its loading makes inspection impracticable.

Question 4

How many numbered hazardous-material hazard classes are recognized in transportation regulations?

  1. A Three
  2. B Six
  3. C Nine
  4. D Twelve

Correct answer: C – Nine

Federal hazardous-materials regulations organize materials into nine numbered hazard classes. They cover explosives, gases, flammable liquids, flammable solids, oxidizers and organic peroxides, toxic and infectious substances, radioactive materials, corrosives, and miscellaneous hazardous materials. Some classes are further divided into divisions.

Question 5

Which is an acceptable way to handle mobile-phone communications while operating a commercial motor vehicle?

  1. A Use a hand-held phone whenever traveling below 35 mph
  2. B Use a compliant hands-free setup or pull safely off the highway and stop
  3. C Hold the phone in the left hand to keep the right hand near the controls
  4. D Use a hand-held phone while temporarily stopped at a red light

Correct answer: B – Use a compliant hands-free setup or pull safely off the highway and stop

Federal rules prohibit a CMV driver from using a hand-held mobile telephone while driving, including while temporarily stopped for traffic or a signal. A compliant hands-free device may be used as described in the CDL manual. A driver may also move safely off the highway and halt where the vehicle can remain stationary; an emergency-services exception applies.

Question 6

Properly adjusted outside convex mirrors on a school bus should provide which views?

  1. A The entire side of the bus up to the mirror mounts
  2. B The front of the rear tires where they touch the ground
  3. C At least one traffic lane on each side of the bus
  4. D All of these views

Correct answer: D – All of these views

The Minnesota CDL manual instructs school bus drivers to adjust the outside convex mirrors to show all three listed areas. These views help monitor traffic, side clearances, students, and the area near the rear wheels. Convex mirrors distort apparent size and distance, so drivers must account for that limitation.
