During a right-angle turn, the vehicle body can cross the line, but the wheels must not press on the line. Below are some precautions regarding vehicle turning: Turning on urban roads: Slow down and yield. Urban areas have heavy traffic and many pedestrians. Before turning, activate the turn signal to indicate your intention. When turning, remember to slow down, look around, and then proceed. Turning in rainy or foggy weather: Visibility is poor in rainy or foggy conditions. When approaching a curve, remember to honk in advance. During the drive, turn on the parking lights and fog lights to make your driving status and position visible to other vehicles, and reduce speed when meeting oncoming traffic. Turning at intersections: Look left and right. When turning at a road intersection, observe in all directions to avoid collisions. If you need to make a left turn, pay attention to traffic signs, activate the turn signal in advance, and try to minimize the turning radius.









As someone who frequently tests driving skills on curves, I've noticed that the car body can indeed cross the line during right-angle turns, especially on unfamiliar road sections. Beginners often cross the line because their turning angle is too wide or they fail to control their speed properly. The car body crossing the line is a safety issue that may lead to scratches or accidents. In actual practice, I've observed that it's essential to slow down to 20-30 km/h before turning and to keep the steering wheel steady without making sudden turns, especially when driving large vehicles with a long wheelbase, as they are more prone to crossing the line. I recommend practicing narrow lane driving more to improve handling. In poor weather conditions, slippery roads increase the risk of accidents—I always brake earlier in the rain, control the entry and exit points of the turn, and ensure the wheels follow the inner path. When driving daily in the city, pay extra attention to mirrors and blind spots at right-angle intersections. Developing this habit can reduce potential hazards. Safety comes first—it's better to drive slower than to risk crossing the line.

I usually drive to and from work. Once, when making a sharp right-angle turn at a narrow intersection, my car went over the line, which gave me quite a scare. It was a tight turn at about 40 km/h, and I turned the steering wheel too sharply, causing the right rear wheel to go outside the lane. Later, I learned my lesson—now I slow down to around 25 km/h before turning, maintain steady throttle, and avoid turning the wheel more than one and a half turns to prevent excessive body drift. The car's track width and wheelbase also play a big role. For example, my SUV is bulkier than a sedan, so it requires a larger turning radius. Now, whenever I approach a right-angle turn, I remind myself to signal early, check for pedestrians on both sides, and reduce risks. I slow down even more in rain or on slopes, as poor road conditions increase the risk of skidding or going off track. With more driving practice, I've gradually learned to handle it better.

With decades of experience in the mechanical field, right-angle cornering and vehicle overstepping issues often stem from physical design. Vehicle turning relies on tire friction, and overly sharp angles can cause wheel slippage or crossing the line. Vehicles with longer wheelbases are more prone to overstepping, especially during right-angle turns where the difference between inner and outer wheels is significant, often causing the outer wheels to press the line. The key to control is reducing speed and maintaining stable steering to prevent tire grip loss. In daily driving, always pay attention to road markings and prioritize safety.

From a risk perspective, improper speed during a 90-degree turn can easily cause the vehicle to cross the line. Based on my extensive driving experience, the key factor in lane crossing during sharp turns is excessive tire load, which may lead to loss of control and potential collisions with pedestrians or obstacles. Preventive measures include reducing speed to a lower gear in advance, making smooth steering adjustments, and coordinating the trajectories of the front and rear wheels. The risk is higher during rainy weather or on uneven road surfaces, so I always remind drivers to slow down and stay aware of their surroundings. Regular vehicle maintenance is also crucial to prevent aggravated issues caused by tire wear.

As a young car owner, making sharp 90-degree turns is quite common, and the car body crossing the line is mainly due to rushed maneuvers. I've driven on many narrow city roads, and at higher speeds, the rear end tends to swing out of the lane during turns, which compromises safety and could lead to fines. I've learned my lesson now—slowing down to 20 km/h before gradually turning the steering wheel. SUVs are harder to control than sedans in these situations. Assistance systems like parking sensors also help a lot. Regular practice with narrow-lane turns can improve skills, making driving more confident and hassle-free.
