Where are the reference points for a right-angle turn?

Reference points for a right-angle turn: The point where the right side of the vehicle is 30 centimeters away from the edge line. Below is relevant information about right-angle turns: 1. Overview: The right-angle turn is an assessment point in Subject 2 of the driver's license test, evaluating the driver's ability to correctly operate the steering and accurately judge the vehicle's inner and outer wheel differentials when driving through sharp turns. 2. Deduction points: Running over the protruding point results in failure; each time the wheels run over the road edge line, 20 points are deducted; completing the maneuver by reversing results in a 10-point deduction; failing to use or incorrectly using turn signals results in a 10-point deduction.
When I was learning to drive, I kept running over the line on 90-degree turns. Later, my instructor taught me three key points. First, keep the car about 30 centimeters from the right line, using the middle of the hood to follow the line steadily. Second, watch the left rearview mirror—when it just passes the corner line, turn the steering wheel all the way to the left. This timing takes practice to get right. Third, observe the front of the car—when the edge of the hood covers the opposite curb, straighten the wheel. Remember to go slow during the turn to leave room for adjustments. Turning too early can be corrected, but turning too late guarantees hitting the corner. Different cars have slightly different reference points. My beat-up training car required turning half a second earlier than a new car, so with a new car, it took a few tries to find the rhythm.
When teaching a friend to practice driving before, I realized that the reference points for 90-degree turns are actually quite flexible. The optimal method is observing when the left door handle aligns about 10-15cm from the inner curb before fully turning the wheel. Another common reference is aligning the outer edge of the side mirror with the corner, though seat height adjustment is crucial. I recommend beginners first practice in an empty area using two water bottles as simulated curbs - entering at a diagonal angle makes steering easiest, and crawling speed ensures safety. During rain/fog, identify reference points earlier as wet surfaces increase braking distance - vehicles often drift outward over half a foot during turns, a detail rarely mentioned in driving schools.
