When to Turn the Steering Wheel for a Right-Angle Turn?
1 Answers
The right-angle turn test requires the driver to navigate a prescribed route at a low speed without stopping, completing the turn in one continuous motion. The vehicle can make a right-angle turn from left to right or from right to left. "Full lock and straighten" is a method to execute a right-angle turn, with the following specific steps: I. Full Lock 1. Preparation for the Turn: Drive close to the outer edge of the road in advance. 2. Timing for the Turn: When the bumper aligns parallel with the inner right angle. 3. Technique: (1) Full Lock: Complete in one motion, turning the wheel to its limit until a "click" sound is heard, turning slightly more than 3 full rotations. (2) Hands remain on the wheel, continuously turning 3 full rotations while simultaneously shifting hands 3 times: First, turn the wheel in the direction of the turn, then use the other hand to pull in the same direction, while the turning hand continues to turn without leaving the wheel, completing 3 full rotations. At this point, a slight additional turn and pull should produce the "click" sound, after which you can stabilize the wheel and adjust hand position. The most effective force application occurs during the upward motion and upper half of the steering wheel rotation. Between the 4 o'clock and 8 o'clock positions, turning the wheel is less effective, and pulling should be prioritized over turning. II. Straighten 1. Timing: When the vehicle is about to align straight. 2. Technique: Use one hand to turn the wheel continuously for 3 full rotations in the direction of the turn.
