Question

Difficulty: HardSteering Techniques

While driving across an uneven bridge transition with deep longitudinal expansion joints, a heavy commercial vehicle experiences severe steering kickback. Which steering grip and hand positioning technique provides optimal vehicle control while preventing hand and wrist injuries?

  1. A
    Locking both thumbs tightly around the inner steering wheel spokes while allowing mechanical free play to absorb wheel deflection
  2. Firmly holding opposite sides of the steering wheel rim with both hands while keeping the thumbs along the outside of the rimAnswer
  3. C
    Steering with the palm of one hand at the top of the wheel while lightly dragging the service brakes through the transition
  4. D
    Relaxing the hand grip to permit the wheel to slide toward center while applying heavy service brake pressure to halt lateral movement

Answer

Firmly holding opposite sides of the steering wheel rim with both hands while keeping the thumbs along the outside of the rim
Safe commercial driving requires placing both hands on opposite sides of the steering wheel with a firm grip. Keeping the thumbs along the outside of the rim ensures that if a tire hits a rut or expansion joint causing the wheel to snap back violently, the spokes will not strike and injure the driver's thumbs.

Step-by-Step Solution

1
Analyze the mechanical risks associated with severe roadway kickback and steering wheel movement
Identify that hitting bumps, potholes, or ruts can violently pull the wheel from the driver's grip and snap the wheel spokes rapidly
Commercial steering systems transmit substantial ground reaction forces directly to the steering assembly when encountering road defects
2
Determine the proper hand placement and two-handed grip standard specified by commercial driving safety guidelines
Both hands must remain on opposite sides of the wheel rim with thumbs positioned outside the rim rather than curled around spokes
This two-handed balance delivers maximum leverage to maintain the vehicle path while preventing thumb fractures if the wheel snaps back
