Sample Alaska CDL Test Questions - General Knowledge

Question 1

Which statement correctly distinguishes Gross Combination Weight (GCW) from Gross Combination Weight Rating (GCWR)?

  1. A GCW is the rated weight of one vehicle; GCWR is the trailer’s actual weight
  2. B GCW excludes cargo; GCWR includes only cargo
  3. C GCW is the combination’s actual total weight; GCWR is a rating used for the combination
  4. D GCW and GCWR are two names for the same measurement

Correct answer: C – GCW is the combination’s actual total weight; GCWR is a rating used for the combination

GCW is the actual combined weight of the power unit, towed units, and cargo. GCWR is a rating rather than a scale measurement. Under the current federal CDL definition, GCWR is generally the greater of a qualifying manufacturer-displayed value or the applicable combined ratings or weights of the power unit and towed units.

Question 2

Under a bridge formula, what generally happens when axles in a group are spaced closer together?

  1. A The allowable weight increases
  2. B The allowable weight decreases
  3. C The allowable weight remains the same
  4. D Axle spacing is no longer considered

Correct answer: B – The allowable weight decreases

The federal bridge formula limits the maximum weight carried on groups of consecutive axles based partly on axle spacing. Shorter spacing generally permits less weight because the load is concentrated over a smaller area of a bridge. Greater spacing can distribute the load across more of the structure, subject to all other axle and gross-weight limits.

Question 3

Which preparation helps reduce distractions before driving?

  1. A Eating a large meal immediately before departure
  2. B Depending on coffee to maintain attention
  3. C Learning the vehicle controls, adjusting mirrors, and programming devices before moving
  4. D Keeping a phone ready for reading or sending messages

Correct answer: C – Learning the vehicle controls, adjusting mirrors, and programming devices before moving

The Alaska CDL manual recommends eliminating in-vehicle distractions before driving begins. Become familiar with the vehicle’s equipment, adjust controls and mirrors, program the route or radio, and secure loose objects before moving. These steps allow the driver to keep attention on traffic instead of performing avoidable tasks while operating the vehicle.

Question 4

Which type of fire may require large quantities of water to cool it completely?

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

Correct answer: A – A tire fire

A burning tire must be thoroughly cooled, and the CDL manual notes that large quantities of water may be needed. Water should not be used on an energized electrical fire because of the shock hazard or on a gasoline fire because it can spread the flames. If the correct method is uncertain, especially with hazardous materials, wait for trained firefighters.

Question 5

If your commercial vehicle must stop on a roadway or shoulder at night, what should you do immediately?

  1. A Activate the four-way emergency flashers
  2. B Wait up to 15 minutes before displaying warning devices
  3. C Leave the left turn signal operating
  4. D Leave the high-beam headlights on

Correct answer: A – Activate the four-way emergency flashers

Federal rules require the driver to activate the vehicle’s hazard-warning flashers immediately after an emergency stop on the traveled roadway or shoulder. The Alaska manual also instructs drivers to use four-way flashers, particularly at night. Required warning devices must then be placed as soon as possible and within ten minutes, not fifteen minutes.

Question 6

What does a red-and-white DO NOT ENTER sign tell a driver?

This sign warns drivers that _________________.
  1. A An expressway entrance is ahead
  2. B Heavy traffic should be expected
  3. C Entry is prohibited and may place the vehicle against the permitted traffic direction
  4. D Proceed slowly after checking for traffic

Correct answer: C – Entry is prohibited and may place the vehicle against the permitted traffic direction

A DO NOT ENTER sign marks a location where a driver must not enter. It is commonly positioned where a driver could wrongly enter a one-way roadway, divided highway, or ramp. A driver facing the sign must not proceed into the restricted roadway and should safely correct course.
