To safely guide a heavy transport combination through an abrupt highway detour lane transition without initiating a rollover or skid, an operator must apply proper steering and countersteering techniques. What is the correct procedural order of steering actions required to perform this lane transition safely?
- 1Establish a firm, balanced two-handed grip on opposite sides of the steering wheel before initiating the maneuver.
- 2Turn the steering wheel smoothly toward the adjacent lane without applying hard service braking.
- 3Countersteer in the opposite direction as the front of the vehicle enters the new lane to arrest rotational momentum.
- 4Straighten the wheel smoothly under continuous two-handed guidance to stabilize the vehicle in the center of the lane.
Answer
The correct sequence begins with establishing a balanced two-handed grip, followed by smooth initial steering into the target lane without braking, executing immediate countersteering to stop turning inertia, and finally straightening the wheel under two-handed control to stabilize the vehicle.
Safe commercial vehicle lane transitions require pre-positioning both hands on opposite sides of the wheel for control, steering smoothly into the target lane without harsh braking, applying immediate countersteer to arrest rotational energy, and guiding the wheel back to center under active hand control.
