Can the Mirrors Cross the Line During Reverse Parking?

[LeBrooklyn]

The position of the mirrors is not a criterion for evaluation; as long as the wheels do not cross the line, it is acceptable. The "Motor Vehicle Driving Training Teaching and Examination Syllabus" stipulates that during reverse parking, as long as the vehicle body does not exceed the ground markings, no points will be deducted. The rearview mirrors are protruding, so whether they are considered part of the vehicle body depends on how each local examination site identifies the rearview mirrors. Crossing the line with the vehicle body, failing to enter the parking space, stopping midway, not following the prescribed route, driving out of sequence, or exceeding the specified time will result in a deduction of 100 points. The full score for the two subjects is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The rules for the second subject of the motor vehicle driver's license application examination state that stopping midway during the examination, rolling back, or not following the voice prompts will result in failure. Wheels or the vehicle body crossing the line will also result in failure. During the second subject learning, many students encounter the issue of crossing the line, and the most common mistake leading to failure is "crossing the line." The main reason for wheels crossing the line is that students fail to master the correct timing for steering. Besides missing the right moment to steer, another reason could be that the steering speed does not match the vehicle speed. Subject 2 Deduction Standards: Not wearing a seatbelt: deduct 100 points. Starting the engine without the gear in neutral: deduct 100 points. Not using the turn signal (including starting, changing lanes, overtaking, turning, and parking); turning on the turn signal for less than three seconds (note that this is easily overlooked!); forgetting to turn off the turn signal or using it incorrectly: deduct 10 points. Stalling once: deduct 10 points. Reverse Parking: Not following the prescribed route sequence: deduct 100 points. Vehicle body crossing the line: deduct 100 points. Failing to enter the parking space: deduct 100 points. Before reversing, failing to have both front wheels touch the ground beyond the control line: deduct 100 points. Exceeding the 210-second time limit for the task: deduct 100 points. Stopping midway for more than 2 seconds: deduct 5 points each time. Slope Parking and Starting: After the vehicle stops, if the front bumper is not aligned with the pole line and exceeds 50 cm forward or backward: deduct 100 points. After the vehicle stops, if the front bumper is not aligned with the pole line but does not exceed 50 cm forward or backward: deduct 10 points. After the vehicle stops, if the starting time exceeds 30 seconds: deduct 100 points. Wheels crossing the road edge line while driving: deduct 100 points. Rolling back more than 30 cm when starting: deduct 100 points. After the vehicle stops, if the vehicle body is more than 50 cm away from the road edge line: deduct 100 points. After parking, not tightening the parking brake: deduct 10 points each time. After the vehicle stops, if the vehicle body is more than 30 cm but less than 50 cm away from the road edge line: deduct 10 points each time. Rolling back more than 10 cm but less than 30 cm when starting: deduct 5 points each time. Parallel Parking: After the vehicle stops in the parking space, if the vehicle body crosses the line: deduct 100 points. Not using or incorrectly using the turn signal when parking: deduct 10 points. Exceeding the 90-second time limit for the task: deduct 100 points. Touching the parking space edge line with the vehicle body while driving: deduct 10 points each time. Wheels touching the lane edge line while driving: deduct 10 points each time. Stopping midway for more than 2 seconds: deduct 5 points each time. Right-Angle Turn: Wheels crossing the road edge line: deduct 100 points. Not using or incorrectly using the turn signal during the turn, or not turning off the turn signal after the turn: deduct 10 points. Stopping midway for more than 2 seconds: deduct 5 points each time. Curve Driving: Wheels crossing the road edge line: deduct 100 points. Stopping midway for more than 2 seconds: deduct 100 points. Driving without the gear in second or higher: deduct 5 points.

When reversing into a parking space, you can use the rearview mirrors to see how the car body aligns with the ground markings. Having driven for over ten years, I’d like to share some tips for novice drivers who frequently park. The side mirrors, in particular, allow you to roughly gauge the distance between the rear wheels or bumper and the edge lines, but there are blind spots in the field of view, especially in tight spaces where gaps can be underestimated. I recommend adjusting the mirror angles before reversing to ensure you can see the ground below the tires, then move the car slowly while watching the line changes in the mirrors to adjust the steering. Don’t rely solely on the mirrors—combining them with leaning out to observe the ground is safer. Practice several times during the beginner phase to develop a good sense of distance. For added safety, installing a rearview camera system can supplement visibility and reduce the risk of scratches.

Regarding the use of rearview mirrors, I have taught most students the technique of reversing into parking spaces and found that mirrors can effectively help judge the trajectory of the wheels sweeping the lines. The key is to adjust the mirror correctly: after sitting upright, the side mirrors should display a portion of the car body and a wide field of view, so that during reversing, the relative position between the wheel edge and the white line can be clearly seen. However, relying solely on mirrors is not enough because the curvature affects perception—the actual distance is closer than what is seen, making it easy to misjudge and cross the line. I recommend combining the sound prompts from the reversing radar to assist in calibration. Before each practice, ensure the vehicle is positioned straight, the mirrors are clean and unobstructed, and develop the habit of checking the mirrors while slightly adjusting the steering wheel to control speed. This can significantly improve the accuracy of judging the wheel sweep.

When reversing into a parking space, the rearview mirror allows observation of the wheels approaching the ground lines, but the limited field of view may lead to misjudging line-crossing situations. The mirrors are designed with a wide-angle view, covering part of the vehicle's side and rear areas to help spot shadows of the wheels crossing the lines, but they cannot precisely determine if the lines are actually being touched. I often encounter this in real driving situations—due to the vehicle's length and blind spots, such as the area beneath the rear bumper being a dead zone, making it easy to overlook subtle line marks. When reversing, don't rely solely on the mirrors; also turn your head to confirm the actual position or use nearby reference points like trees or other vehicles. Develop a habit of moving slowly to avoid sudden turns. In short, mirrors are supplementary tools; comprehensive judgment is needed to prevent accidents.

From a vehicle design perspective, the rearview mirror can partially display wheel line-sweeping during reverse parking, but I've analyzed that this depends on the car model and installation position. Standard side mirrors reflect ground lines with approximately 5-10 meters of visibility. When reversing, drivers can perceive whether the rear wheels sweep over lines through angle changes, but errors of several centimeters may occur due to mirror curvature and height. If the lines are too thin or the road surface is uneven, visibility becomes even more challenging. Based on my driving experience, I recommend upgrading to electrically adjustable mirrors for enhanced flexibility and activating the reverse camera system for full-angle monitoring. Don't rely solely on mirrors—combining parking sensor readings provides more reliable assistance. Regular maintenance to keep mirror surfaces clean and avoid blurriness will improve accuracy.

When driving safely, using the rearview mirror to check the reversing line is feasible, but it requires cautious use. I have personally experienced parking issues several times, where the mirror can display a blurry image of the rear wheels approaching the ground line, helping to roughly estimate alignment with the parking line. However, the blind spots are significant, especially the complete invisibility of the lower rear part of the car, which can easily lead to misjudgment and cause scratches. I emphasize not to rely solely on the mirror—turning your body to observe the actual environment is more crucial, or asking a partner to assist with guidance. For beginners, it is recommended to practice mirror adjustment in an open area and learn to use auxiliary devices such as reverse radar alarms. Maintain low speed when reversing, stop multiple times to check the position, and ensure the safety of both people and the car comes first.
