Sample Questions

Question 1
When a heavy rigid truck or articulated combination vehicle makes a right turn at an urban intersection, what primary factor creates the hazardous right-side blind spot often referred to as the 'Death Zone' (死亡盲区)?
The inner wheel difference (内轮差), where the rear wheels follow a significantly tighter turning arc than the front steering wheels
The aerodynamic downforce created by the front bumper deflecting side airflow
The pneumatic brake lag between the foot valve and the trailer relay valve
The reflection of the curb mirror distorting distance perception in direct sunlight
Question 2
How does vehicle wheelbase (轴距) affect the inner wheel difference (内轮差) and turning radius when operating a heavy commercial truck?
A longer wheelbase produces a larger inner wheel difference, requiring a wider outward swing before turning
A longer wheelbase reduces the inner wheel difference, allowing tighter turns near the curb
Wheelbase length has no mathematical relationship to inner wheel difference, which is governed solely by tire width
A shorter wheelbase requires the driver to cross oncoming lanes to avoid curb contact
Question 3
According to GB 1589-2016 regulations on axle loads and vehicle dimensions, what is the primary risk of loading cargo too far toward the rear of a heavy truck cargo bed?
It reduces downforce on the front steering axle, leading to degraded steering control and headlight upward mispointing
It causes immediate pneumatic failure of the service brake dual-circuit diaphragm
It locks the transmission inter-axle differential into permanent 4-wheel engagement
It increases front tire temperature and accelerates front tread wear
Question 4
When securing palletized heavy goods on an open flatbed cargo truck, which of the following restraint practices is required under PRC Road Freight Transport Safety Regulations?
Using certified ratchet tensioners, tie-down straps, and high-friction rubber dunnage mats across all cargo units
Relying solely on the vehicle's side dropsides without additional top-over lashings
Securing only the rearmost pallet and leaving intermediate pallets free to settle naturally
Tying cargo exclusively with natural hemp ropes secured directly to the wheel rims
Question 5
When backing a semi-trailer combination vehicle (重型半挂车) into a narrow loading dock, how must the driver initially manipulate the steering wheel to guide the rear of the trailer to the left?
Turn the steering wheel to the right initially, then counter-steer to the left once the trailer begins pivoting
Turn the steering wheel immediately to the hard left and hold it stationary throughout the maneuver
Engage the differential lock and accelerate briskly in reverse without steering inputs
Pump the service brake pedal continuously while keeping the steering wheel centered
