Why should ropes never be used as the primary securing method for heavy steel coils or machinery?

Choose one answer below.

ARopes do not have sufficient tensile strength or tensioning capabilities to restrain heavy, dense loads✓BUK laws ban the carrying of ropes on flatbed vehicles✓CRopes cause chemical reactions with steel under tension✓DRopes interfere with the vehicle's ABS electrical circuits✓

Choose one answer below.

ATo improve the aerodynamic flow of the vehicle cab✓BTo act as a physical barrier preventing the load from sliding forward into the driver's cab during heavy braking✓CTo display the operator's corporate branding and license details✓DTo support the weight of the semi-trailer when uncoupled✓

QUESTION 13 / 25

What is a major risk of placing a heavy, concentrated load directly in the middle of a long trailer bed without support?

Choose one answer below.

AIt will cause the tyres to deflate instantly due to air pressure changes✓BIt can cause chassis bending, structural cracking, or trailer failure due to concentrated stress✓CIt automatically disables the engine speed limiter✓DIt increases the maximum steering lock angle of the cab✓

QUESTION 14 / 25

What safety check must you perform on a curtain-sided vehicle before opening the side curtains at an unloading point?

Choose one answer below.

QUESTION 17 / 25

In cargo transport guidelines, how does the 'friction coefficient' affect your load securing calculations?

Choose one answer below.
