A driver will operate a straight truck with a GVWR of 28,000 pounds while towing a trailer rated at 9,500 pounds. No passenger or hazardous-material endorsement is involved. Which CDL class is required?
Correct answer: B - Class B, because the truck qualifies and the trailer is 10,000 pounds or less
During a pre-trip inspection, both front steering tires measure 3/32 inch in every major groove; the drive tires also measure 3/32 inch. No cords are exposed. Which statement correctly evaluates these measurements?
Correct answer: A - The vehicle fails because steering-axle tires require at least 4/32 inch
A 70-foot tractor-trailer is traveling 55 mph on dry pavement. Under the standard CDL following-distance rule, what minimum interval should the driver establish before adding extra space for traffic or weather?
Correct answer: C - 8 seconds
A driver inspected the cargo at departure and again 50 miles into the trip. Since that check, the truck has traveled 140 miles over 3 hours 10 minutes without a break. The driver should conclude that:
Correct answer: C - The inspection became due at 3 hours, before 150 miles
A front tire blows out while a loaded straight truck is moving at highway speed. The truck pulls sharply toward the failed tire, but the lane ahead is clear. What is the best immediate response?
Correct answer: B - Hold the wheel firmly, avoid braking at first, and let speed fall
At about 35 mph in heavy rain, a tractor begins to hydroplane and the steering feels light. Which action gives the tires the best chance to regain traction?
Correct answer: A - Ease off the accelerator and avoid braking until traction returns
Before descending a long grade, a driver selects a safe speed of 40 mph and the proper low gear. Using snub braking, which pattern is correct?
Correct answer: D - Brake firmly near 40 mph, release near 35 mph, and repeat as needed
An aggressive motorist tailgates a loaded truck, flashes headlights, and repeatedly tries to pass. Traffic ahead leaves room to increase the truck's following distance. What should the commercial driver do?
Correct answer: C - Increase space ahead, signal early, and let the motorist pass when safe
During the static air-leakage test on a chocked tractor-trailer, the engine is off, parking brakes are released, and the service brake is not applied. After stabilization, pressure drops 2.7 psi in one minute with no audible leak. How should this result be interpreted?
Correct answer: B - Pass the numerical limit; a combination must lose less than 3 psi per minute
With the vehicle secured, a driver tests a dual air-brake system with the engine off. The low-air warning first activates at 52 psi. The spring-brake control later pops out at 32 psi. How do these readings compare with the required test values?
Correct answer: A - The warning test fails, although the spring-brake pop-out is within range
