REAR VIEW MIRROR
Once the desired position is obtained, the rear view mirror must be adjusted to enable vision of all and / or most part of the windscreen. If a door mirror is fitted, it should be also adjusted as to ensure that a part of the side of the car can be seen. This would eliminate the 'blind spot'.
Ideally, left and right hand door mirrors should be fitted as it then eliminate both 'blind spot'.
Remember: Correctly adjusted mirrors are your 'rear view eyes' and enables you to observe what situation is developing behind you. As a rule you should make it a point to look into your rear view mirrors 8 to 10 seconds.
