A straight truck has a GVWR of 28,000 lb and tows a trailer with a GVWR of 9,500 lb. It carries neither passengers nor placard-required hazardous materials. Which CDL class applies to this combination?
Correct answer: C - Class B, because the power unit is at least 26,001 lb and the trailer is 10,000 lb or less
A 60-foot tractor-semitrailer is traveling 50 mph on a dry, level highway. The driver times a 5-second gap to the vehicle ahead. Using the CDL following-distance rule, what adjustment is needed?
Correct answer: A - Increase the gap to at least 7 seconds
During a pre-trip inspection, a driver measures tread depth at the major grooves: left steering tire 5/32 inch, right steering tire 3/32 inch, drive tires 2/32 inch, and trailer tires 3/32 inch. Which finding makes the vehicle unsafe to dispatch?
Correct answer: D - The right steering tire at 3/32 inch
At highway speed, a front tire suddenly blows and the truck pulls sharply toward that side. Which response best preserves control?
Correct answer: B - Grip the wheel, avoid braking initially, and let the vehicle slow before moving off
A driver of an open-deck load checks cargo securement 45 miles after departure. Ninety minutes later, the driver stops for fuel and changes from driving to on-duty not driving. No shifting is visible. What must be done before resuming the trip?
Correct answer: B - Reinspect the cargo and securement now
Before a long downgrade, a driver selects 40 mph as the safe speed and shifts to the proper low gear. Which braking pattern matches the snub-braking method?
Correct answer: D - Apply the service brakes firmly for about 3 seconds to reach roughly 35 mph, release them, and repeat when speed returns to 40 mph
Near 3:00 a.m., a driver begins missing signs, drifting within the lane, and cannot remember the last several miles. The most defensible action is to:
Correct answer: A - Stop at a safe legal location and sleep
During the applied air-leakage test on a tractor-semitrailer with one trailer, the engine is off, the parking brakes are released, the wheels are chocked, and the full service brake is held after the initial pressure drop stabilizes. The gauges lose 4.6 psi in one minute. How should this result be interpreted?
Correct answer: C - Fail; the maximum permitted loss is 4 psi in one minute
On a long descent, both air-pressure gauges remain in the normal range and no low-air warning activates. Even so, progressively more pedal pressure is needed, stopping response weakens, and a hot lining odor develops. Which diagnosis best fits the pattern?
Correct answer: D - Brake fade from excessive heat
During a stationary CDL air-brake check, the warning buzzer and lamp first activate at 48 psi. What conclusion follows?
Correct answer: B - The warning activates too late and the defect must be corrected
