The most effective way to adjust rearview mirrors to “avoid blind spots” in 2023

What is a rearview mirror, and what is the safest and most effective way to adjust the rearview mirror? The article below CarOn will answer your questions!

What is a car rearview mirror?

Car rearview mirrors are part of the car’s mirror system, used to help drivers see behind and around the car during driving. Rearview mirrors are located on the outside and inside the vehicle’s cabin, allowing the driver to see directions and surrounding vehicles without having to turn around or lose direct vision outside.

Classification of rearview mirrors

Rearview mirror in the cabin (rearview mirror)

Mounted on the front of the cab, the cabin rearview mirror allows the driver to see the rear of the vehicle by reflecting light from the outside rearview mirror. This is the main rearview mirror to observe behind and view the image on the mirror while driving.

Side mirrors

Outside rearview mirrors are mounted on either side of the door or above the car door, allowing the driver to see behind and to the sides of the vehicle. The outside rearview mirror can be adjusted to optimize the driver’s visibility.

Blind spot mirrors

Separate rearview mirrors are often attached to the outside rearview mirror, helping the driver observe blind areas that make direct vision unclear. Separate rearview mirrors are specially designed to provide wider visibility and minimize blind spots.

These types of rearview mirrors together create a complete observation system to help drivers drive safer and more conveniently.

Why do you need to adjust the car rearview mirror?

Adjusting the rearview mirror is important and necessary to ensure safe driving. Here are the reasons why it is necessary to adjust the car rearview mirror properly:

Helps make vision clearer

Properly adjusting the rearview mirror helps the driver have a clear view of surrounding directions and vehicles. If the mirror is not positioned correctly, it can cause loss of vision, causing danger and disruption while driving.

Detect blind spots

Properly adjusting the rearview mirror helps detect blind spots, i.e. areas that cannot be seen directly from the driver’s seat. By optimally adjusting your mirrors, you can minimize blind spots and improve visibility.

Monitor sitting position easily

Each person has a different sitting position in the car, so adjusting the rearview mirror to suit your sitting position is very important. You should adjust the mirror so that you can clearly see important directions without having to bend your head or turn your body.

Reduce glare

Properly adjusting your rearview mirrors can reduce glare from other vehicles, especially from behind. By adjusting your mirrors so that glare is reflected away from your eyes, you can minimize the possibility of glare while driving.

How to adjust the rearview mirror correctly

Currently there are two ways to adjust rearview mirrors for cars

How to adjust a narrow angle mirror

Step 1: Adjust the rear mirror vertically (up – down direction) so that the bottom edge of the mirror can see half of the front door handle.

Step 2: Adjust the rear mirror horizontally (outward – inward direction) so that the image of the side of the car takes up ¼ of the horizontal width in the mirror, the image of the side of the car near the rear takes up the remaining ¾.

Step 3: Adjust the center rearview mirror so that the rear window image is in the center of the mirror.

Advantage This way of adjusting the mirror helps maximize visibility of the side and rear of the vehicle, providing effective support when moving the vehicle into parking lots or narrow roads.

Defect Because it mainly focuses on the rear of the car, the body of the car has a fairly large blind area. This makes it difficult for the driver to observe vehicles moving parallel to the side when changing direction or changing lanes. In addition, when adjusting the mirror this way, because the mirror faces inward (narrow angle), the image in the outside rearview mirror easily overlaps with the central rearview mirror.

Adjust the rearview mirror

How to adjust wide angle mirror

Step 1: The driver tilts his head to touch the side of the car, adjusting the driver’s side mirror so that it covers the entire rear quadrant of the driver’s side.

Step 2: The driver leans toward the center of the vehicle, adjusting the passenger side rearview mirror so that it covers the entire rear quadrant of the passenger side.

Step 3: Adjust the center rearview mirror so that the rear window image is in the center of the mirror.

Because the vehicle structure and mirror size of each vehicle are different, it is necessary to check to see if blind spots have been minimized. After adjusting all three interior and exterior rearview mirrors, observe the edge of the central rearview mirror and determine the beginning and end of the visible image. Next, look at the edges of the rearview mirrors on both sides. Adjust the car mirror correctly when the image on the edge of the inside mirror just touches the image on the edge of the outside mirror. At this time, the image of the outside mirror does not overlap with the inside mirror, nor does the observation area miss out.

Advantage The way to adjust a wide-angle car rearview mirror is to help the three mirrors combine to form a seamless strip of reflection, providing a panoramic view. So when anything happens behind, for example the car behind overtakes, the image of that car will change from the center mirror to one of the two outside rearview mirrors. This type of mirror adjustment helps the driver see well the area on both sides of the vehicle, thereby being able to change lanes and change directions more safely.

Defect This way of adjusting the mirror does not allow you to see the rear of the car as well as adjusting the narrow angle. This is quite disadvantageous when you need to back up, park or move the car onto a narrow road.

Signs that the rearview mirror needs to be replaced

  • Broken or damaged mirrors: If your rearview mirror is broken or damaged to the point of being unusable, it’s a clear sign that you need to replace it.
  • Loss of adjustment function: If the rearview mirror cannot be adjusted, cannot be moved or locked in a fixed position, it is a sign that the mirror needs to be replaced. Failure to adjust mirrors can cause loss of visibility and reduce driving safety.
  • Fogginess or fogging: If the surface of the rearview mirror is foggy or shows signs of fogging, it can affect your ability to see. In this case, replacing the mirror will ensure you have clearer vision and safer driving.
  • Mirrors are no longer solid: If the rearview mirror becomes loose or no longer solid when you move it or adjust it, this can make it difficult to maintain position and visibility. In this case, replacing the mirror with a new one will be necessary to ensure the stability and effectiveness of the mirror.
  • Mirrors lose their anti-glare feature: Some rearview mirrors have an anti-glare feature to reduce glare from other vehicles. If this feature does not work or is no longer effective, you should consider replacing your mirrors for a better driving experience in difficult lighting conditions.

If you experience any of the above signs, you should check and replace your car rearview mirror immediately to ensure safety and good visibility when driving.

However, the price to replace a rearview mirror will range from: 700,000 – 3,500,000 VND depending on the vehicle type and subdivision.
