Many contents will be revised in the standards for mirrors used in cars.

The Ministry of Transport is drafting a Circular promulgating the National Technical Regulation on mirrors for automobiles - revised 01:2023 QCVN 33:2019/BGTVT.

Accordingly, the new Draft has many noteworthy points as follows:

(1) Camera-monitor system (CMS) is a system of equipment used to observe the rear, side or front of the vehicle within the observation range specified in Appendix A of this Regulation by combining camera-monitor defined as follows:

- A camera is a device that records images of the outside world and then converts these images into signals (for example, video signals).

- A monitor is a device that converts signals into images that are displayed in the visible spectrum.

The term Camera-monitor (CMS) in Standard 33:2019/BGTVT is replaced by the term Camera-monitor System (CMS).

(Current QCVN 33:2019/BGTVT stipulates: Camera-monitor (CMS) is a system of equipment used to observe the rear, side or front of the vehicle within the observation range specified in Appendix A of this Regulation by combining the camera-monitor defined as follows:

- A monitor is a device that converts signals into images that are displayed in the visible spectrum.

(2) Mirror type: rearview mirrors are considered to be of the same type if they have the same brand, manufacturer, manufacturing address and there is no difference in the following main technical characteristics:

- The design of the mirror cluster includes the details connecting to the vehicle if any.

- Mirror type, mirror shape, size and radius of curvature of the reflecting surface.

(Current regulations: Mirror type: rearview mirrors are considered to be of the same type if they have the same brand, manufacturer, production line and there is no difference in the following main technical characteristics:
