Zorluk: KolayAdjusting Margins in Ice and Snow

You are parked on a residential road that has become covered in compacted ice and snow. What action should you take when moving off to reduce the risk of wheel spin?

  1. A
    Rev the engine hard in first gear before quickly releasing the clutch
  2. Select second gear and gently ease off the clutchCevap
  3. C
    Pump the footbrake vigorously while accelerating
  4. D
    Accelerate sharply to build immediate forward momentum

Cevap

Select second gear and gently ease off the clutch to move off smoothly without spinning the wheels.
Selecting second gear reduces the torque transferred to the driven wheels. Combined with gentle clutch control and light accelerator pressure, this provides the best chance for the tyres to find grip on ice and snow without spinning.

Adım Adım Çözüm

1
Assess the surface condition and recognize the lack of tyre adhesion on ice and snow.
Identified that high torque from first gear will cause the tyres to slip.
Compacted snow and ice significantly reduce friction between the tyres and the road.
2
Select a higher gear (second gear) and apply light, progressive throttle while releasing the clutch smoothly.
The driven wheels turn with reduced rotational force, allowing the vehicle to move off smoothly.
Second gear limits torque output, which helps maintain traction and prevents wheel spin.

Anahtar Kavram

Using a higher gear when moving off on ice or snow reduces wheel torque and minimizes the risk of wheel spin.
