A commercial driver is approaching a sharp freeway off-ramp curve while transporting a loaded combination vehicle. Place the actions for safe curve speed management and vehicle control into the correct chronological order from first to last.
- 1Evaluate the advisory speed, road surface conditions, and cargo weight during the straight approach.
- 2Apply service brakes smoothly in a straight line before entering the curve to reduce vehicle speed below the posted advisory speed.
- 3Downshift the transmission into the appropriate gear before reaching the point of curvature.
- 4Apply light, steady throttle through the curve to stabilize the combination unit and maintain driving traction.
Cevap
The correct sequence is: (1) Evaluate advisory speed, surface conditions, and cargo weight on the straight approach, (2) Apply service brakes in a straight line before the curve, (3) Downshift into the proper gear before reaching the turn, and (4) Apply light, steady throttle through the curve.
Safe curve negotiation requires completing all deceleration and gear selection actions on the straight roadway before turning begins. Assessing conditions and advisory signs establishes the target speed; applying brakes in a straight line eliminates side-load braking forces; downshifting prior to the turn secures engine power control; and applying light, steady throttle through the arc keeps the vehicle balanced and tracking securely.
