Will Turning Too Close to the Edge Cause a Failed Turn?

[LandonLee]

Turning too close to the edge during a right-angle turn can easily result in hitting the corner, leading to a failed test. When entering a right-angle turn, it is recommended to drive close to the left line, maintaining a distance of approximately 30 centimeters from it. Below is additional information regarding right-angle turns: Deduction Points for Right-Angle Turns: Wheels touching the protruding point: disqualification; Wheels touching the road edge line once: 20-point deduction; Using reverse to complete the maneuver: 10-point deduction; Failing to use turn signals or using them incorrectly: 10-point deduction. Techniques for Right-Angle Turns: Drive as close to the outer edge of the road as possible, straighten the vehicle, and proceed slowly at a low gear; When your body (shoulder) is parallel to the turning point, quickly steer the wheel; When the front of the car is aligned with the exit of the turn, swiftly straighten the wheel to exit. Alternatively, you can observe the rearview mirror to track the movement of the rear wheels—when the rear wheels are about to pass the turning point, straighten the steering wheel.

I've been driving for nearly twenty years and have encountered many situations where turning too close to the curb is an issue. If you drive straight too close to the roadside, the turning radius becomes insufficient when making a right-angle turn. In such cases, the front of the car might scrape against the corner, and the rear wheels could easily ride over or even get stuck on the curb. This is especially noticeable with larger vehicles. Last time, my SUV almost grazed a flower bed during a right turn. It's crucial to observe the road conditions in advance. Ideally, you should move slightly toward the center of the road before turning to leave enough lateral space. When turning, avoid jerking the steering wheel too sharply; turn it steadily and keep a close eye on the inner wheel position via the rearview mirror to maintain a safe distance.

As an experienced driver, I find the distance when turning and pulling over is really something to pay attention to. If you get too close to the curb when entering a turn, the front wheels might make it, but the rear wheels' trajectory will swing inward—this is what we call the 'inner wheel difference.' Last month, I saw a sedan turn too sharply, and its right rear wheel ended up riding onto the sidewalk curb, scratching the rim. Before making a turn, it's crucial to straighten the car's position in advance, not wait until the last moment to adjust. If the road is narrow, I might borrow a bit of space from the opposite lane, but safety must be ensured. Extra caution is needed when driving long-wheelbase vehicles like pickup trucks or vans, as they have a higher failure rate in turns.

Turning techniques are actually related to vehicle characteristics. The difference in inner wheel clearance varies greatly among different cars. For example, the compact electric car I drive is particularly agile in turns, easily navigating tight right-angle corners close to the curb. However, driving my friend's long-wheelbase business sedan is completely different - attempting the same turn in the same position might get stuck. I recommend beginners first practice in an empty area by repeatedly testing safe distances with the car parked at right-angle positions. Remember to reduce speed below 20 km/h before turning, steer decisively but not abruptly, and leaving half a meter as a safety margin is most prudent. Pay special attention to the rear wheel position through the rearview mirror - this perspective makes distance judgment easier than looking at the front of the car.

From the perspective of vehicle dynamics, failure to turn and pull over is mainly due to the limitations of steering geometry. When a vehicle drives straight close to the roadside, an angle is formed between the front wheel steering angle and the trajectory of the inner rear wheel, especially during right-angle turns where this angle is maximized. Here's how I handle it when driving: start slowing down about five meters before the turn while shifting the car about thirty centimeters toward the center of the road. When making sharp turns, avoid turning the steering wheel all the way at once—turn it about 80% first, observe the position of the car's front end, and then make adjustments. Be extra cautious on roads with high curbs, as the sidewalls of tires are particularly vulnerable to being scraped by the curb. Once on a rainy day, I wasn't paying attention and ended up with a small chip on the wheel rim.

The issue of cutting corners during turns is actually related to driving visibility. I'm accustomed to turning my head to check blind spots before entering a turn, which helps assess whether there's sufficient space. When driving straight with the vehicle close to the curb, the A-pillar can obstruct part of the view, increasing the chance of misjudging distances. I recommend developing a three-step turning method: first, angle the car body about 30 degrees before turning; then, pay attention to the change in distance between the rear wheels and the roadside in the rearview mirror during the turn; finally, check if the car body is completely within the lane after turning. Right-angle turns on narrow residential roads are the most challenging. I always honk in advance to alert oncoming vehicles before proceeding slowly. It's okay if the rear wheels slightly touch the grass, but hitting the hard curb would be troublesome.
