1108. Where is the permitted to untie tools or a trailer from the tractor?
  • On a cement or asphalt surface only.

  • On an inclined plane, to make it easier for the harnessed tool.
  • On a leveled surface, to prevent accidental movements.

1110. What is the function of the tractor’s middle lift arm (“the third point”)?
  • To prevent vertical freedom of movement of the arms and of the tool.
  • To secure the harnessed tool with special security chains.
  • To prevent sideways freedom of movement of the arms and to prevent the tractor turning.
  • To lift the tool a few times to maximum height in order to ensure that the tool is properly harnessed.

1111. Which action should be taken after the tool is harnessed to the hydraulic lift arms?
  • Lifting the tool a few times to maximum height in order to ensure that the tool is properly harnessed.
  • Preventing vertical freedom of movement of the arms and of the tool.
  • Preventing horizontal freedom of movement of the arms and of the tool.
  • Securing the harnessed tool with special security chains.

1112. How would a tractor and its trailer maintain low speed during a long and steep descent?
  • By driving in low gear and relying on the engine’s compression braking .
  • By regulating the speed with the brakes.
  • By using the trailer’s brakes and locking the differential.
  • By operating the engine brake and driving in low gear.

1183. It is prohibited to drive too close to the vehicle in front of you:
  • During the dark only.
  • Only when the weight of the vehicle in front is more than 4 tons.

  • Depends on the size of the tires.
  • Is not dependent on speed at all.

1292. What should a driver do when he approaches a road section on which oil was spilled?
  • Drive faster and avoid stepping on the brake pedal.
  • Slow down as moderately as possible, and avoid heavy l braking.
  • Move the wheel left and right intermittently while driving on the oil.
  • Continue driving normally, because the oil helps to increase tire-road friction.
