Sample Wisconsin CDL Test Questions - General Knowledge

Question 1

A CDL holder is convicted of a nonparking traffic offense committed in a personal vehicle. When must the employer be notified?

  1. A Within 74 hours
  2. B Within 3 days
  3. C Within 30 days
  4. D Within 30 days, but only if the offense occurred in a CMV

Correct answer: C – Within 30 days

Federal CDL rules require a driver to notify each current employer within 30 days after conviction for a traffic-control violation other than a parking violation. The requirement applies regardless of whether the driver was operating a commercial or personal vehicle. The reporting period begins with the conviction, not merely the issuance of a citation.

Question 2

Which activity is not one of the three general areas of a CDL skills test?

  1. A Operating material-handling equipment
  2. B Inspecting the vehicle
  3. C Demonstrating basic vehicle control
  4. D Driving on the road

Correct answer: A – Operating material-handling equipment

Wisconsin's CDL manual identifies three general skills-test areas: vehicle inspection, basic vehicle control, and on-road driving. Operating forklifts or other material-handling equipment is not part of the CDL skills examination. All three driving-related segments must be completed in the required order using a representative vehicle.

Question 3

A CMV is stopped on the traveled portion or shoulder of a divided highway. Where should the three warning devices be placed?

  1. A At 50 feet, 100 feet, and 150 feet in both directions
  2. B At 100 feet, 50 feet, and 50 feet behind the vehicle
  3. C At 10 feet, 100 feet, and 200 feet toward approaching traffic
  4. D At 100 feet ahead, 100 feet behind, and 10 feet beside the vehicle

Correct answer: C – At 10 feet, 100 feet, and 200 feet toward approaching traffic

The federal rule requires warning devices at approximately 10 feet, 100 feet, and 200 feet from a stopped CMV in the direction of approaching traffic on a one-way or divided highway. This arrangement gives approaching drivers progressively earlier notice. Drivers placing the devices should keep them between themselves and approaching traffic.

Question 4

When there is too little room to stop in an emergency, steering around the hazard may be the safer response.

  1. A TRUE
  2. B FALSE

Correct answer: A – TRUE

Stopping is not always the safest emergency response. If the available distance is insufficient, steering into a clear escape path may prevent a collision. The driver must know what is beside the vehicle, maintain control, and avoid braking while making a very sharp evasive turn.

Question 5

Which conditions are tire problems that should be identified during an inspection?

  1. A Excessive or insufficient air pressure
  2. B Abnormal wear or tread separation
  3. C Cuts or other visible damage
  4. D All of the above

Correct answer: D – All of the above

Commercial drivers should inspect tires for incorrect pressure, bad wear, tread separation, cuts, exposed fabric, damaged valve stems, and other defects. Each listed condition can affect the tire's ability to carry the load and maintain control. Problems should be identified before the vehicle is placed in service.

Question 6

Containerized freight is generally used when:

  1. A Hazardous-materials requirements do not apply
  2. B The shipment is exempt from weight limits
  3. C Part of the journey is made by rail or ship
  4. D No cargo securement is necessary

Correct answer: C – Part of the journey is made by rail or ship

Containerized loads are commonly used when freight travels part of the journey by rail or ship, with truck transportation at the beginning or end. Some containers lock directly onto a specially designed frame, while others are carried on flatbed trailers. Regardless of the arrangement, the container must be properly secured.
