Generally, the vehicle body can touch the line during a right-angle turn. Evaluation criteria for right-angle turns: The vehicle must follow the prescribed route, making a right-angle turn from left to right or right to left, passing through in one go without stopping. According to the "Motor Vehicle Driver Examination Content and Methods," the evaluation criteria for right-angle turns specify that the wheels must not press against or touch the road edge lines, but there is no mention of the vehicle body not being allowed to touch the lines. Tips for right-angle turns: Turn on the turn signal when entering the right-angle turn area, keeping the vehicle body 30 centimeters away from the road edge line; when the inner door handle is parallel to the inner corner of the turn, turn the steering wheel fully to the left or right; straighten the steering wheel once the vehicle is aligned and smoothly exit the examination area.

I've been driving for over twenty years, and absolutely no part of the car body should cross the line during a right-angle turn—this is a major no-no in driving tests. I remember when I took my Category 2 test in my younger days, just a tiny bit of the rear end crossing the line cost me ten points, nearly failing me. On regular roads, crossing the line might seem minor, but it can easily lead to accidents, like hitting a roadside flower bed or scraping another car's paint, which isn't cheap to fix. Develop good habits: slow down before turning, judge the angle correctly, steer precisely, and the car will stay neatly within the lines. Don't underestimate this detail—it's about safe driving and vehicle control. Beginners often overlook it, but with a bit more practice, it becomes second nature.

I just started learning to drive, and during right-angle turns at the driving school, I often get scolded by the instructor because the car body touches the line. Last week during a mock test, I got nervous while making a right-angle turn, failed to control the wheels properly, and the car body brushed against the white line. The instructor said this was improper positioning and would result in a major penalty, which is very dangerous. In actual driving, touching the line poses significant risks. If you accidentally hit the curb on a narrow street or cross the line and violate traffic rules, it could be troublesome. The instructor taught me a little trick: slow down before turning, check the rearview mirror, and quickly steer the wheel into position, so the car body can perfectly avoid the line. Keep practicing, don’t rush, precise control is the real skill.

From a vehicle design perspective, right-angle turn body sweeping is often caused by inaccurate turning radius calculations. Due to the existence of the inner wheel difference, larger vehicles are more prone to this issue. The lines set during testing are designed to assess the driver's spatial control ability, and sweeping directly reflects vehicle control errors. From a safety standpoint, sweeping may lead to driving onto sidewalks or opposing lanes, increasing the risk of collisions. It is recommended to estimate the vehicle's trajectory length during turns and operate the steering wheel at a constant speed to easily avoid this problem. In driving, details determine success or failure.

As a long-distance driver, I deeply understand that safety comes first, and it's strictly forbidden for the car body to sweep the line when making a right-angle turn. This not only violates traffic rules and results in immediate failure in exams, but can also cause accidents in daily life—sweeping the line encroaches on others' space or leads to scratches from running over the line, resulting in significant losses. My driving habit is to observe the surroundings, slow down before turning, and steadily steer the wheel to ensure the car body turns smoothly within the lines. Developing this good habit can save you countless troubles and protect both your vehicle and your safety. It never hurts to be more careful—driving requires caution.
