,1. An inspection reveals this condition; which action is supported by the principle that
Trailer air-brake systems require adequate air pressure, sound lines, correct valves,
and functioning brake components.. Which answer best applies to the underlying
transport trailer mechanic period 1 concept in this situation?
A. Trailer suspension components support loads and maintain axle alignment and ride
characteristics..
B. Trailer air-brake systems require adequate air pressure, sound lines, correct valves, and
functioning brake components..
C. Wheel-end inspection should consider bearings, seals, hubs, wheels, fasteners, and tire
condition..
D. Lighting systems require correct lamps, wiring, connectors, grounds, and secure mounting..
Correct answer: B
Rationale: The correct choice directly states the governing principle: Trailer air-brake systems
require adequate air pressure, sound lines, correct valves, and functioning brake
components.. The alternatives address related topics but do not directly answer the issue
being tested.
2. Which option demonstrates the most accurate understanding of how Wheel-end
inspection should consider bearings, seals, hubs, wheels, fasteners, and tire
condition.. Which answer best applies to the underlying transport trailer mechanic
period 1 concept in this situation?
,A. Trailer suspension components support loads and maintain axle alignment and ride
characteristics..
B. Wheel-end inspection should consider bearings, seals, hubs, wheels, fasteners, and tire
condition..
C. Coupling devices must be inspected for secure engagement, wear, damage, and proper
operation..
D. Lighting systems require correct lamps, wiring, connectors, grounds, and secure mounting..
Correct answer: B
Rationale: The correct choice directly states the governing principle: Wheel-end inspection
should consider bearings, seals, hubs, wheels, fasteners, and tire condition.. The alternatives
address related topics but do not directly answer the issue being tested.
3. When diagnosing or planning work, which statement is most accurate about Trailer
suspension components support loads and maintain axle alignment and ride
characteristics.. Which answer best applies to the underlying transport trailer mechanic
period 1 concept in this situation?
A. Trailer suspension components support loads and maintain axle alignment and ride
characteristics..
B. Coupling devices must be inspected for secure engagement, wear, damage, and proper
operation..
C. Lighting systems require correct lamps, wiring, connectors, grounds, and secure mounting..
, D. Trailer electrical wiring should be protected from abrasion, moisture, and mechanical
damage..
Correct answer: A
Rationale: The correct choice directly states the governing principle: Trailer suspension
components support loads and maintain axle alignment and ride characteristics.. The
alternatives address related topics but do not directly answer the issue being tested.
4. Which statement most accurately explains the principle involved when Lighting
systems require correct lamps, wiring, connectors, grounds, and secure mounting..
