Sample Alaska CDL Test Questions - General Knowledge

Question 1

A CMV driver must be placed out of service for 24 hours when which alcohol condition is found while the driver is on duty or operating?

  1. A An alcohol concentration of 0.10% or higher
  2. B Any measured alcohol concentration or detected presence of alcohol
  3. C An alcohol concentration of 0.05% or higher
  4. D An alcohol concentration of 0.04% or higher

Correct answer: B – Any measured alcohol concentration or detected presence of alcohol

Federal regulation prohibits a CMV driver from having any measured alcohol concentration or detected presence of alcohol while on duty, operating, or in physical control of a CMV. A driver who violates this prohibition must immediately be placed out of service for 24 hours. The period begins when the out-of-service order is issued.

Question 2

A RESERVED PARKING sign displaying the wheelchair accessibility symbol designates what?

This sign indicates ___________.
  1. A A space reserved for authorized vehicles used by or transporting a person with a disability
  2. B An area where all parking is prohibited
  3. C A parking space available to any vehicle
  4. D A short-term commercial loading area

Correct answer: A – A space reserved for authorized vehicles used by or transporting a person with a disability

The Accessible Parking sign displays the International Symbol of Accessibility and designates a space reserved for persons with disabilities. Alaska law restricts parking in such a space to vehicles meeting the applicable permit, plate, operator, or passenger requirements. It is not a general-use or loading space.

  1. A 10 to 12 seconds
  2. B 8 to 10 seconds
  3. C 12 to 15 seconds
  4. D 15 to 17 seconds

Correct answer: C – 12 to 15 seconds

A commercial driver should normally look at least 12 to 15 seconds ahead. This provides time to identify traffic changes and determine whether there is room to slow, stop, or change lanes. The driver must continue shifting attention between nearby conditions and the roadway farther ahead.

Question 4

An individual cargo article is 8 feet long and is not blocked against forward movement. At least how many tiedowns are 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 that is longer than 5 feet but no longer than 10 feet, regardless of its weight. Different minimums apply to shorter, lighter articles and to cargo that has been blocked against forward movement. Longer articles may require additional tiedowns.

Source: 49 CFR § 393.110(b) — Additional requirements for determining the minimum number of tiedowns

Question 5

How should you adjust your driving when another vehicle is following too closely?

  1. A Brake suddenly to warn the other driver
  2. B Continuously operate the four-way flashers
  3. C Increase the space between your vehicle and the traffic ahead
  4. D Signal the other driver to pass immediately

Correct answer: C – Increase the space between your vehicle and the traffic ahead

The Alaska CDL manual recommends increasing your following distance when you are being tailgated. More space ahead allows you to slow gradually and avoid abrupt maneuvers that could contribute to a rear-end collision. It can also provide the following driver with a better opportunity to pass.

Question 6

Water should not be used on which pair of vehicle fires?

  1. A Tire and paper fires
  2. B Wood and cloth fires
  3. C Electrical and gasoline fires
  4. D Paper and cardboard fires

Correct answer: C – Electrical and gasoline fires

Water must not be used on an electrical fire because it can create an electrical-shock hazard. It also should not be used on a gasoline fire because it can spread the burning fuel and flames. Water may be appropriate for ordinary combustibles such as wood, paper, or cloth.
