CDL Basic Vehicle Control Practice Test Part 2

1. When backing a tractor-trailer, what is the correct relationship between steering wheel input and trailer movement direction?

2. Which backing direction is preferred when maneuvering a commercial vehicle into a loading dock or parking space?

3. A driver needs to back a tractor-trailer into a loading dock during heavy rain with reduced visibility and wet pavement. The dock area has limited space and the driver cannot see the dock clearly through mirrors due to rain on the mirror surfaces. What is the safest approach for this backing maneuver?

4. A driver is approaching a right turn at an intersection in a 65-foot tractor-semitrailer. The intersection has a dedicated right-turn lane and a concrete curb on the right side. The driver understands off-tracking will cause the trailer’s rear wheels to follow a path inside the tractor’s path. What technique should the driver use to prevent the trailer from riding up on the curb or swinging into the adjacent lane?

5. A driver needs to back a tractor-semitrailer into a dock space located between two parked trailers in a narrow alley. The approach requires a 90-degree alley dock maneuver with approximately 12 feet of clearance on each side of the target dock space. What sequence of actions represents the correct approach for this complex backing maneuver?

6. A driver is backing a loaded tractor-semitrailer on an icy parking lot. As the driver steers to align the trailer with a dock, the rear of the trailer begins to slide sideways despite slow backing speed. The driver recognizes this as a trailer skid during backing. What is the correct response to recover control of the trailer?

7. During a CDL skills test, an applicant must perform driver-side parallel parking with a tractor-semitrailer. The target space is approximately 75 feet long with a vehicle parked at the front end of the space. The applicant approaches correctly positioned but makes an error in the backing sequence that causes the trailer to approach the space at too sharp an angle. What correction should the applicant make to successfully complete the maneuver?

8. A driver approaches a loading dock in a busy warehouse yard with multiple vehicles maneuvering. The dock space is narrow with obstacles (parked forklifts) on both sides. The driver must back from a perpendicular approach angle (alley dock) but notices a forklift crossing behind the trailer’s intended path. The forklift operator does not appear to see the truck. Which analysis correctly prioritizes the driver’s actions for this complex situation?

9. A driver is backing a tractor-semitrailer toward a dock in a confined warehouse area. The driver has performed GOAL (Get Out And Look) twice already, confirming adequate clearance on both sides. As the trailer approaches the dock (approximately 20 feet remaining), the driver considers whether to perform another GOAL or complete the backing using mirrors alone. Which factors should influence the driver’s decision to perform additional GOAL checks?

10. A CDL applicant is preparing for the basic vehicle control skills test and practices offset backing (left) repeatedly. During practice, the applicant notices a consistent pattern: the trailer drifts left during backing, requiring multiple corrections to stay aligned with the target box. Which analysis correctly identifies the likely cause and appropriate practice focus for this pattern?
