For vertical adjustment, position the distant horizon at the center of the mirror. For horizontal adjustment, set the car body to occupy 1/4 of the mirror's surface area. Place the horizon line at the 2/3 position of the rearview mirror; then adjust the edge of the car body to occupy 1/4 of the mirror's image. The rear window should be centered in the rearview mirror, with the left and right positions adjusted so that the left edge of the mirror just cuts off the right ear of your reflection in the mirror.

















Adjusting the mirrors for Subject 3 is crucial as it directly impacts driving safety and exam pass rates. Here's my years of experience: the interior rearview mirror should be centered to ensure a full view of the rear window, with slight head movements covering blind spots. The side mirrors should be adjusted to show a small portion of the car's side, like above the rear wheel arch, while leaving most of the view for the road behind to spot adjacent vehicles when changing lanes. Avoid setting them too high or too low, as examiners may deduct points for incomplete visibility. Remember to adjust after assuming the standard driving posture, practice simulating real road conditions, and always check before driving. Quick adjustments during the exam and forming these habits in daily practice can prevent accidents.

I just passed the third subject of the driving test last time, and adjusting the rearview mirrors is crucial. The inner mirror should be aligned straight with the center of the rear window to clearly see the cars behind. My technique for the outer mirrors is to adjust them so that a small part of the car body, like the rear door handle, plus the ground and the car behind, are visible, but not angled too far outward. Failing to adjust them properly during the test could lead to failure. My instructor taught me to adjust the mirrors after sitting upright and to check the side blind spots by turning my head during the test. If you notice any mistakes, such as the mirrors being adjusted too inward or outward, correct them immediately. It's recommended to frequently use the mirrors in combination with turning your head for a safe and efficient test pass.

As someone who drives frequently, adjusting the mirror positions is essential to avoid blind spots and accidents. The interior rearview mirror should be centered for a clear view of the rear. The side mirrors should show a small portion of the car body and a large portion of the road behind—never overlook these details. This is emphasized in the Subject 3 driving test; adjusting them quickly can minimize point deductions. Making it a habit ensures safer daily driving.

When adjusting the mirrors, the standard sitting posture is the key point. Adjust the interior rearview mirror to the center position of the rear window, and set the exterior rearview mirrors at an angle of about 15 degrees to show a portion of the car body while capturing most of the road view. This setup minimizes blind spots and makes it easier to pass the test. It is recommended to confirm the positions before starting the vehicle to avoid frequent adjustments.

When taking the driving test for Subject 3, it's crucial to carefully adjust the rearview mirrors. I always emphasize to my child when teaching them to drive: the interior mirror should cover the entire rear window view, while the exterior mirrors should divide the body-side proportion, such as 1/4 of the car body plus 3/4 of the rear ground. Failing to adjust them properly during the test may result in failure. Get accustomed to the correct positions during practice, and always complement mirror checks with head turns to ensure no blind spots, making driving safer and more stable.
