Zorluk: KolayVehicle Adjustments for Heavy Loads (Tyres & Headlights)

Carrying a heavy load in the boot causes the rear of your car to dip and the front to rise. How should you adjust your dipped headlights before driving at night?

  1. A
    Adjust the headlight beam aim upwards
  2. Adjust the headlight beam aim downwardsCevap
  3. C
    Switch to main beam headlights permanently
  4. D
    Reduce the front tyre pressures

Cevap

The headlight beam aim should be adjusted downwards to avoid dazzling oncoming road users.
When a vehicle is heavily loaded at the rear, the back drops and the front lifts up. This tilts the dipped headlights higher, which can blind oncoming drivers. Adjusting the headlights downwards restores the beam to the correct level on the road.

Adım Adım Çözüm

1
Identify the physical effect of a heavy rear load on vehicle pitch
The extra weight depresses the rear suspension, causing the front of the vehicle to lift and tilting the headlight beams higher than normal.
This altered vehicle posture causes standard dipped headlights to shine directly into the eyes of oncoming drivers.
2
Apply the appropriate adjustment control
Use the internal headlight leveling adjuster to angle the light beams downwards.
Deflecting the beam downwards restores the correct illumination area on the road surface ahead without causing dazzle.
