A Massachusetts applicant will operate a straight truck rated at 27,500 pounds GVWR while towing a trailer rated at 9,000 pounds GVWR. No passenger or hazardous-material trigger applies. Which CDL class matches this vehicle?
Correct answer: C - Class B; the truck is 26,001 pounds or more and the trailer is 10,000 pounds or less
At highway speed, the left steering-axle tire suddenly blows. The truck pulls left, but the lane ahead is open. Which action should come first?
Correct answer: A - Hold the wheel firmly, stay off the brake initially, and keep straight
A 60-foot tractor-semitrailer is traveling 48 mph on dry pavement. A car merges ahead, leaving a five-second gap. Using the CDL following-distance rule, what interval must the driver restore?
Correct answer: D - Seven seconds - six for length, plus one for speed above 40 mph
A 14,000-pound machine is secured with three chains rated at 2,000 pounds working load limit each. The chains are correctly attached, but no other securement is present. Which conclusion is correct?
Correct answer: B - The system is 1,000 pounds short of the 7,000-pound aggregate minimum
During the pre-trip check, the ABS lamp stays on after its self-check. A low-speed service-brake test is straight and normal, and no other brake defect is found. How should the driver treat the finding?
Correct answer: B - Use normal braking cautiously and arrange prompt ABS repair
On a long downgrade, each snub requires more pedal pressure than the previous one to produce the same speed reduction. Air pressure remains normal. Which explanation best fits the pattern?
Correct answer: D - Brake fade from excessive heat
A scheduled bus must carry an otherwise permitted small HAZMAT shipment because no practical alternative exists. After loading, one permitted hazard class would total 80 pounds and all permitted HAZMAT would total 400 pounds. No prohibited material is involved. Which decision complies with passenger-vehicle limits?
Correct answer: A - Accept it because both the 100-pound class limit and 500-pound total limit are met
A passenger bus becomes disabled on a narrow shoulder where unloading riders would place them directly in live traffic. A tow vehicle can move the bus a short distance to a protected turnout. Which operating choice complies with passenger-safety rules?
Correct answer: C - Move only to the nearest safe unloading point, then discharge the passengers
A fully charged tractor-trailer is secured on level ground. With the engine off and parking brakes released, pressure drops 2.4 psi in one minute. With at least 90 psi applied to the service brakes, it drops 3.6 psi in one minute. How should these results be interpreted?
Correct answer: D - Both leakage tests pass
While building air pressure, the compressor never unloads. Pressure reaches about 150 psi and the safety valve repeatedly vents. Which component is most likely failing to control the pressure cycle?
Correct answer: A - Compressor governor
