CDL Basic Vehicle Control Practice Test Part 3

1. What is the recommended steering method for commercial motor vehicles?

2. You are driving a 65-foot tractor-semitrailer and need to make a right turn at an intersection. The curb is 10 feet from the edge of the right lane. What is the correct procedure to prevent the trailer from off-tracking into the curb or sidewalk?

3. Which of the following is the preferred side for backing a tractor-semitrailer when a choice is available?

4. You are backing a tractor-semitrailer toward a loading dock on the driver’s side. You need the trailer to move further to the left (toward the dock). How should you turn the steering wheel?

5. During the CDL skills test, you are performing straight-line backing. You notice the trailer is drifting toward the right boundary line. What corrective action should you take FIRST?

6. You are backing a tractor-semitrailer into a narrow alley dock space. You cannot clearly see the dock from the cab due to limited mirror visibility. What should you do before continuing to back?

7. During offset backing (right offset), your tractor-trailer combination starts aligned in the left lane and must end aligned in the right lane, parallel to the starting position. Midway through the maneuver, you realize the trailer angle is too sharp and the rear is approaching the right boundary. What analysis should guide your next action?

8. You are making a right turn from a two-lane road onto a four-lane road in a tractor-semitrailer. A vehicle is waiting to turn left from the opposite direction in the oncoming lane. You observe that if you turn wide into the left lane of the four-lane road, the oncoming vehicle may turn simultaneously into the right lane. What is the safest analysis and action?

9. During alley dock backing, you must back your tractor-semitrailer 90 degrees into a dock space from a narrow alley. You have set up at an angle and begun backing. The trailer is now at approximately 45 degrees to the alley. What steering action is needed to continue the approach?

10. During the CDL skills test basic control exercises, the examiner records three pull-ups and one outside vehicle observation (GOAL) during your straight-line backing maneuver. The maneuver was completed without any encroachments (boundary crossings). How should you analyze this performance outcome?
