There are numerous safety systems you can use on your vehicle, and the car rear view mirror is one part of this broad system. Poor design of rearview mirrors has been considered as the cause of a lot of automotive deaths since this can be placed in such a way that your car has extra blind spots that can potentially cause you to pull out right in front of another incoming vehicle.
A quality rearview mirror can do several things. First, it can reduce blind spots and show a larger portion of the road behind you as well as the sides. Rearview mirrors can also have reduced glare to allow you to see even during nighttime when lights from vehicles behind you can make you blind to subtle road signs. The rearview mirror must also be clear enough for it reflect vivid details, lights, and colors. In the event of road accidents, the rearview mirror must also break away to ensure that it doesn’t cause any additional harm to passengers.
