0837. What reason justifies an unexpected pull from the roadway into the “hard shoulder”?

  • Sudden appearance of an undesirable element in the driving lane.
  • When another vehicle stops in the opposite lane without giving an appropriate signal.
  • Ringing of the vehicle's cellular phone.
  • Technical malfunction in the vehicle’s air conditioning system.

0838. What is the risk in braking while being forced to pull onto the “hard shoulder”?

  • The Vehicle may spin as a result of braking on different types of road surfaces that have different grades of friction.
  • Loss of steering ability as a result of excessive air pressure in the tires.
  • Loss of steering ability as a result of excessive brake use.
  • Vehicle spinning, because its front wheels become locked.

0839. What are the characteristics of a mountain road?

  • Many pedestrians and animals.
  • Wide and unmarked roadways.
  • Mountain roads are never paved.
  • Narrow and winding roadway, sharp curves, bends and sudden slopes.

0840. What risks are expected whilst driving on a mountain road?

  • Engine heating due to excessive use of the brakes.
  • Loss of braking ability and head-on collision. Difficulty yo pull off the road.
  • Tire overheating.
  • Loosening of a wheel due to the road's steep slope.

0841. How can we minimize the risk of brake loss while driving on a mountain road?

  • It is advisable to use the brakes without utilizing the engine’s braking power.
  • Drive in anappropriate (low) gear and avoid excessive use of the brakes.
  • Don’t use the brakes much and stay on high gear.
  • Do not change gears along the mountain road.

0842. How can you avoid frontal collision while driving on a narrow and winding mountain road?

  • Drive close to the middle line.
  • Slow down and honk continuously before every curve.
  • Drive on the far right of the roadway, turn-on the lights, and adjust your speed to the road’s conditions.
  • Drive in high gear and don’t use the brakes much, to avoid loss of braking ability.

0843. What causes a vehicle to skid on the roadway?

  • Quick wear of the clutch and of the gearbox.
  • When the braking forces or the vehicle's inertia exceed the tire’s ability to grip of the roadway.
  • Excessive change of gears.
  • When the engine is worn out and cannot stabilize the vehicle.

0844. While braking and slowing down, what force of nature is applied on the vehicle?

  • No force of nature affects the vehicle while it is braking or slowing down.
  • The force of inertia, i.e. the force which causes the vehicle to continue moving.
  • The centrifugal force, i.e. the force applied on the vehicle when it is turning.
  • The lift force, i.e. the force that pulls the vehicle upwards.
| «C1» | «C» | «D» | «A» | «1» | «В» |

0845. While turning, what natural force pushes the vehicle against the direction of the turn?

  • Gravity.
  • Centrifugal force.
  • The force of inertia.
  • None of the natural forces affect the vehicle while turning.
| «C1» | «C» | «D» | «A» | «1» | «В» |

0846. What are the elements that contribute to vehicle skidding?

  • The old age of the vehicle.
  • Road visibility conditions.
  • Every element that prevents direct contact between the tire and the roadway, such as: water, oil, mud, gravel, etc.
  • Any element which affects the driver's alertness.
