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

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

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

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 edge of the projection shall not be less than 2.5 mm and shall be able to move into the interior of the protective housing when a force of 50 N is applied to the outermost point of the largest projection 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 do not need to comply with the above radius requirements but must have a blunt edge.

Parts of rearview mirrors 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.
