Sample Alaska CDL Test Questions - General Knowledge

Question 1

A yellow diamond sign showing the roadway dividing into two branches warns of what ahead?

This sign warns drivers to _____________.
  1. A. A T-intersection
  2. B. A Y-intersection
  3. C. A road construction area
  4. D. A dip at an intersection

Correct answer: B. – A Y-intersection

In Alaska, this symbol warns that the roadway approaches a Y-shaped intersection. Intersection warning signs provide advance notice of the intersection and the possibility of turning or entering traffic. Adjust your speed as conditions require and watch both branches of the intersection.

Question 2

The signal is green, but there is not enough room beyond the intersection for your vehicle. What should you do?

  1. A. Wait before entering until sufficient space is available
  2. B. Enter and stop in the intersection
  3. C. Sound the horn and continue through
  4. D. Change lanes within the intersection to get around traffic

Correct answer: A. – Wait before entering until sufficient space is available

Alaska regulation prohibits entering an intersection unless enough space exists on the other side to accommodate your vehicle without obstructing vehicles or pedestrians. This requirement applies even when a traffic signal indicates that you may proceed. Remain behind the intersection until your entire vehicle can clear it.

Question 3

According to the Alaska CDL manual, the average driver's reaction time is approximately:

  1. A. ¼ to ½ second
  2. B. ¾ second to 1 second
  3. C. 1½ to 2 seconds
  4. D. 2 to 3 seconds

Correct answer: B. – ¾ second to 1 second

The manual uses an average reaction time of three-quarters of a second to one second under ideal conditions. During that interval, the vehicle continues moving before the brakes are physically applied. At 55 mph, the manual estimates that reaction distance alone is about 61 feet.

  1. A. A railroad crossing is ahead
  2. B. Only trucks may use the road ahead
  3. C. Drivers must pass trucks on the left
  4. D. Trucks may enter or cross the roadway unexpectedly

Correct answer: D. – Trucks may enter or cross the roadway unexpectedly

The truck warning symbol identifies a location where trucks might enter the roadway unexpectedly. It may be used where entering truck traffic would not be readily anticipated or where sight distance is restricted. Watch for large vehicles entering, leaving, or crossing your path.

Question 5

A yellow diamond sign with a short road branching from the right side of the main road warns of:

This sign warns drivers to _____________.
  1. A. A one-way street beginning to the right
  2. B. Traffic approaching only from the left
  3. C. A side road joining from the right
  4. D. A reverse turn ahead

Correct answer: C. – A side road joining from the right

The side-road symbol shows the general configuration of an upcoming intersection. A branch on the right warns that a road joins the main roadway from that side and that turning or entering traffic might be present. Scan the side road and adjust your speed when necessary.

Question 6

After an emergency move onto a clear right shoulder, what is the preferred way to return to the roadway?

  1. A. Stay on the shoulder until stopped, then signal and check the mirrors before returning
  2. B. Brake hard and steer sharply back onto the pavement
  3. C. Turn sharply onto the pavement and then brake hard
  4. D. Maintain speed and immediately drift back onto the pavement

Correct answer: A. – Stay on the shoulder until stopped, then signal and check the mirrors before returning

If the shoulder remains clear, stay on it until the vehicle has stopped. Avoid braking until speed has dropped to about 20 mph when possible, and then brake gently to reduce the risk of skidding on a loose surface. Before returning to the roadway, signal and check your mirrors.
