As a vehicle comes up to pass you in the left lane, it will first appear well behind you in the rearview mirror. As it progressively gets closer to you in the left lane, it will eventually disappear from view in the rearview mirror and, as it does, it should then begin to appear in your side-view mirror. For most vehicles, you will then notice that the passing vehicle will remain in the side view mirror until it eventually appears in your peripheral vision as it leaves the view of the side mirror. You have now eliminated your blind spot.

Fido.

One can use small circular concave rear view mirrors which can easily fit on the side of side view mirror. The smaller mirror I am referring to has sticky material and can easily fit onto the side view mirror.The mirror is very helpful for checking blindspots and I find that 100% successful for me.

That is available in Canadian Tire.

The mirror I am referring to is like oval or egg shape.
