Sample questions

1. The “hinged drawbars” are drawbars attached to the trailer so as to move freely:

   • only in the horizontal plane
   • only in the vertical plane
   • both in the horizontal and vertical planes

2. The “coupling locks” are used to couple trailers to the coupling balls of the towing vehicles.

   • correct
   • incorrect

3. The coupling devices are classified according to their type and are divided into:

   • standard
   • non- standard
   • over-sized
   • specialized

4. The process of “automatic coupling” requires the use of:

   • automatic coupling devices
   • coupling devices, which require additional actions by a mechanic

5. The “steering wedges” are attached to the semi-trailer and together with the fifth wheel coupling assure the steering of the semi-trailer when coupling.

   • correct
   • incorrect

6. The “fifth wheel couplings” include an automatic coupling lock by means of a coupling pin attached to the semi-trailer.

   • correct
   • incorrect

7. The “non-standard drawbars” may consist of several components and may be adjustable or folding.

   • correct
   • incorrect

8. The “fifth wheel couplings” are attached to:.

   • towing vehicles
   • the trailers

9. A “non-standard mounting plate” may have provision to move:

   • horizontally (for instance, sliding fifth wheel)
   • vertically

10. The “coupling ball and towing bracket” is used to couple the trailer by means of a coupling lock.

    • correct
    • incorrect
