Zorluk: KolayWinter Driving

Direct sunlight frequently melts snow and ice on open highway lanes, but pavement inside shaded tree cuts and underneath bridges can remain frozen and slick. Which action should a commercial driver take when approaching these shaded roadway sections?

  1. A
    Maintain normal highway speed on approach and apply firm service braking once the tires enter the shaded pavement.
  2. Slow down smoothly before entering the shaded zone and avoid sharp steering or abrupt braking while crossing it.Cevap
  3. C
    Activate the engine retarder on its highest setting to maintain steady momentum across the shaded surface.
  4. D
    Maintain standard dry-pavement following distance behind other traffic because the majority of the route is dry.

Cevap

Slow down smoothly before entering the shaded zone and avoid sharp steering or abrupt braking while crossing it.
Shaded pavement stays colder longer and can retain hidden ice sheets even when adjacent open roads are dry. Slowing down ahead of time on dry pavement and traversing the shaded patch with smooth, steady inputs preserves wheel traction and avoids skidding.

Adım Adım Çözüm

1
Identify the hidden hazard in shaded road sections during cold weather.
Recognize that shaded areas do not receive direct sunlight and frequently harbor lingering ice even when surrounding open pavement appears clear and dry.
Anticipating traction changes prevents surprise loss of vehicle control.
2
Adjust vehicle speed and controls ahead of time.
Decelerate smoothly on dry pavement prior to the shaded area and maintain gentle, steady vehicle inputs across the slick surface.
Braking or steering abruptly while tires are over slippery ice easily triggers drive-wheel or steer-axle skids.
