You are operating a 53-foot combination vehicle in the right lane of a divided highway with two lanes traveling in your direction. The roadway ahead curves sharply to the right. A passenger car in the left lane is pacing your trailer, occupying the lateral space directly adjacent to your blind spot. Recognizing that the right shoulder is composed of soft dirt and your trailer will inherently track toward it during the curve, what is the most strategically sound maneuver to manage your space to the sides?
- Decelerate gently before entering the curve to clear the passenger car from your left side, allowing you to safely position your tractor closer to the left lane line to keep the trailer's rear wheels on the paved surface.Cevap
- BMaintain a perfectly centered tractor position within the right lane at your current speed, relying on the standard lane width to absorb the trailer's natural off-tracking path without encroaching on the left lane.
- CShift your tractor as close to the right edge line as possible before the curve to maximize your lateral safety cushion from the pacing car, holding this rightward position throughout the curve.
- DEnter the curve at your current speed, and if the trailer tires begin to drop onto the soft shoulder, apply the brakes firmly while steering slightly to the left to pull the trailer back onto the pavement.
Cevap
Decelerate gently before entering the curve to clear the passenger car from your left side, allowing you to safely position your tractor closer to the left lane line to keep the trailer's rear wheels on the paved surface.
The correct maneuver addresses the side-by-side entrapment before the curve becomes a hazard. By decelerating early, the driver allows the pacing vehicle to pull ahead, opening up the lateral space on the left. This allows the driver to position the tractor toward the left side of the lane during the right curve, effectively countering the trailer's rightward off-tracking and keeping the rear wheels safely on the pavement.
