Subject 3 straight-line driving is judged by the computer. The content of the Subject 3 test is as follows: Road driving skill test content: preparation before getting on the car, light simulation test, starting, straight-line driving, gear shifting operation, lane changing, parking on the side, passing through intersections straight, turning left at intersections, turning right at intersections, passing through pedestrian crossings, passing through school areas, passing through bus stops, meeting cars, overtaking, turning around, and driving at night. Safety and civilized driving common sense test content: safety and civilized driving operation requirements, safe driving knowledge under bad weather and complex road conditions, emergency handling methods in case of tire blowouts and other emergencies, and post-accident handling knowledge, etc.

I just took the Category 3 driving test last week, and that time I crossed the line left a deep impression. During the test, the car had GPS positioning and sensors. If you crossed a solid line, the system would beep immediately to alert, and the examiner would check the screen to confirm. The examiner said the computer monitors route deviations in real-time, including crossing dashed and solid lines, while the human examiner mainly ensures safety and overall scoring. When I was practicing, my instructor reminded me to always signal early and check the mirrors when turning, as most line-crossing violations are detected by the computer. Because the system is highly sensitive, it’s easy to trigger alerts at intersections or when changing lanes. The examiner doesn’t watch every move closely but focuses more on safe driving. I think the test system is quite fair, but you still need to practice more to avoid silly mistakes affecting your pass rate.

I've taken the driving test several times, so I'm quite familiar with the issue of crossing lines. The computer evaluation system is key, while the examiner mainly oversees the overall process. For instance, in the Category 3 test, the car is equipped with position sensors that automatically flag line crossings, and the examiner confirms them before scoring. Don't assume the examiner will overlook minor mistakes—crossing lines with high risk will result in a fail. My advice is to stay calm during the test, maintain a steady speed, and pay close attention to road markings. The system is precise, but it's important to develop good habits during practice, like avoiding unnecessary steering adjustments when driving straight. Generally, the computer detects line crossings more frequently, with minimal examiner intervention unless violations are too obvious.

I understand the driving test rules, where line crossing is judged by both the computer and the examiner. The test vehicle is equipped with electronic devices that monitor wheel positions in real time; crossing the line triggers an alarm, and the system automatically records it. The examiner is human-controlled, primarily responsible for overall performance. Line crossing is mainly determined by the computer, which is accurate and fast.

I think the driving test is quite fair, as crossing the line is mostly judged automatically by the computer. The system uses GPS and sensors to track, and driving over a solid line directly results in a fail. The examiner only checks the screen prompts. My friend who took the test said the examiner doesn't pay much attention to details unless the driving is extremely poor. It's recommended to practice more on simulated test routes, as crossing the line often happens at turning points. The rule is mainly technical judgment with human assistance to avoid cheating.

As an instructor, I've taught many students, and the issue of crossing lines is frequently asked about. In the exam vehicle, the system first detects line crossings, and the computer automatically penalizes; the examiner then checks overall safety. For example, during road driving, the system is sensitive, issuing immediate warnings upon crossing lines, with the examiner responsible for the final score confirmation. It's advisable to familiarize yourself with the route markings before the test and drive slowly and steadily. In most cases, the computer handles line crossings, while the examiner ensures the process runs smoothly.
