, Class A/B Knowledge test Questions & Answers
1. Who is responsible for inspecting a vehicle's cargo?
› The driver
It is a driver's responsibility to inspect their cargo; recognize overloading or poorly balanced
weight; know that the cargo is properly secured and not obscuring their view; and know that
the cargo does not restrict access to emergency equipment. The driver is always responsible
for their cargo, even if they were not the one who initially loaded and secured the cargo.
2. What is the penalty for operating a CMV that is placarded for hazardous materials while you are
under the influence of alcohol?
› Losing your CDL for three years
Operating a commercial motor vehicle (CMV) while under the influence of alcohol will
normally result in the loss of one's CDL for at least one year. If an operator is under the
influence of alcohol while operating a CMV that is placarded for hazardous materials, this
increases to at least three years.
3. During the steering box portion of the vehicle inspection test, you should not:
› Assume all cotter keys are present.
Before a trip, ensure that the steering box is securely mounted. Check for missing nuts,
bolts, and cotter keys. Be sure that there are no power steering fluid leaks and that there is
no damage to power steering hoses.
4. During a vehicle inspection, ensure that the landing gear is:
› Fully raised.
When inspecting a trailer during a vehicle inspection test, ensure that its landing gear has no
missing parts and that it is fully raised. The crank handle should be secure and the support
frame should not be damaged.
