Is it illegal to ride a motorbike with only one mirror?

However, in reality, many people do not take seriously the installation of motorcycle mirrors or only install one mirror. So is it illegal to install only one rearview mirror?

According to Point a, Clause 1, Article 17 of Decree 100/2019/ND-CP, a fine of VND 100,000 to VND 200,000 shall be imposed on motorcyclists who do not have a left rearview mirror or have one that is not functional.

Thus, if a motorbike only installs one mirror, and that mirror is on the left, it will not be fined. On the contrary, if only one mirror is installed, and that mirror is on the right, it will be fined according to Point a, Clause 1, Article 17 of Decree 100/2019/ND-CP, with a fine of 100,000 VND to 200,000 VND.

Rearview mirrors installed on vehicles must meet the requirements specified in QCVN 28:2010/BGTVT such as:

All mirrors must be adjustable for field of view.

The edge of the reflecting surface shall be contained within the protective housing (mirror base) and the edge of the protective housing shall have a radius of curvature “c” of not less than 2.5 mm at all points and in all directions. If the reflecting surface protrudes from the protective housing, the radius of curvature “c” of the outer edge of the protrusion shall not be less than 2.5 mm and shall be able to move towards the inside of the protective housing when a force of 50 N is applied to the outermost point of the largest protrusion relative to the protective housing in a direction perpendicular to the reflecting surface.

All parts of the mirror must have a radius of curvature “c” not less than 2.5mm.

The edges of mounting holes or recesses less than 12mm wide need not comply with the above radius requirements but must be dulled.

Rearview mirror parts made of materials with a hardness not greater than 60 Shore A are not required to comply with the requirements stated in 2.1.2 and 2.1.3 according to QCVN 28:2010/BGTVT.
