While all blind zones cannot be eliminated, properly positioned mirrors are the key to maximizing your field of vision.
To set your mirrors, with the vehicle safely parked, sit in the normal driving position. Center the rearview mirror and then adjust the left and right side-view mirrors until you can slightly see the edge of the rear of your vehicle in the mirror. This mirror adjustment will enable you to see adjoining traffic lanes, as well as hazards next to the vehicle. It also provides a reference to the position of your vehicle compared to other vehicles and hazards.
After you adjust your mirrors, you should always glance over your shoulder to check blind zones any time you turn, merge, or change lanes.
