CDL Full Practice Test Part 14

1. A driver has loaded a dry van trailer and positioned most of the heavy cargo toward the rear of the trailer, leaving relatively light weight toward the front near the trailer nose. During the pre-trip inspection, the driver notes that the drive axle weight shows only 10,000 lbs on the CAT scale while the trailer tandem shows 34,000 lbs. What handling effects will this improper weight distribution create, and what should the driver do before departure?

2. A driver is operating a loaded tractor-semitrailer during extreme heat with ambient temperature at 110°F. What is the correct speed management approach to reduce tire blowout risk?

3. A driver needs to test the trailer brakes before coupling a tractor to a semitrailer. The driver has connected the air lines and supplied air to the trailer. Which control should the driver use to apply only the trailer brakes for this test?

4. When making a right turn with a tractor-semitrailer, why must the driver pull forward into the intersection before beginning the turn?

5. 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?

6. During the offset backing maneuver, a driver realizes they cannot complete the maneuver without crossing a boundary line. What should they do?

7. After backing under a trailer and coupling, what test should the driver perform to verify the fifth wheel is properly locked around the kingpin?

8. A driver begins a long-distance trip at 6:00 PM, planning to drive until the 14-hour limit expires at approximately 10:00 PM. The route includes rural highways with minimal lighting. At 9:30 PM, the driver notices significant glare sensitivity from oncoming headlights, feels difficulty maintaining lane position, and experiences occasional “drifting” thoughts. The driver’s last meal was at noon and last rest break was at 3:00 PM. What factors are contributing to the driver’s deteriorating performance, and what comprehensive action should be taken?

9. A driver is descending a steep grade with a loaded trailer. The driver notices the trailer pushing the tractor slightly during braking. What brake imbalance issue is occurring, and what should the driver do?

10. What is the maximum number of hours a property-carrying driver may drive after taking 10 consecutive hours off duty?
