Key Reference Points for 90-Degree Left Turn Techniques
2 Answers
90-degree turn is an assessment point in Subject 2 of the driver's license test, evaluating the driver's ability to correctly operate steering and accurately judge the inner/outer wheel track difference when driving through sharp turns. Engage first gear, release handbrake, slowly lift clutch to maintain semi-engagement for steady forward movement. Key reference points are as follows: Entry: Align the "exam" character with the right boundary line, maintaining about 30cm distance between vehicle body and the line, then drive into the corner. Left Turn: When the left rearview mirror aligns with the inner corner of the turn (or when the hood covers the yellow line ahead), turn the steering wheel left and continue forward. Exit: When the vehicle hood aligns with the exit, quickly straighten the steering wheel and proceed. After the vehicle completely exits the corner, the 90-degree turn is completed.
In my experience driving trucks, the key reference points for making a sharp left turn are crucial. Start braking and slowing down 20-30 meters before the turn while observing the traffic signal at the intersection—if it's a green light for left turns, don't rush, and ensure there's no risk of the light suddenly turning yellow. As the front of the vehicle approaches the corner, immediately check the left blind spot: there are often pedestrians or electric scooters darting out unexpectedly, so safety comes first. When starting to turn the steering wheel, focus on the curb reference point, slowly turning the wheel a quarter to half a turn, and align the front of the truck with the centerline of the exit road to avoid cutting the corner or crossing the line. During the turn, move your eyes like a scanner, scanning from the sidewalk to the opposing lane to prevent unexpected conflicts. In rainy or foggy conditions, brighten your headlights and take extra glances at road reflectors. With practice, these reference points become second nature, making driving more confident—but never overlook the rules, and remind your friends not to get complacent either.
