Every vehicle comes equipped with side view mirrors but there are no instructions on how to properly set them. The idea may sound naive, but even some experienced drivers do not know how to efficiently use side view mirrors. If you can see the side of your vehicle while looking at your mirrors, they are not set properly. Side view mirrors are not intended to see what is directly behind you - that is why you have a rearview mirror. Side view mirrors, however, are intended to spot vehicles in your blind zone. When set properly, side view mirrors can help you avoid devastating auto claims.
Side mirrors should be turned away from the side of your vehicle so they reflect the image of cars in the left and right lanes that are approaching from the rear. Your left mirror should be set to relay the image of a vehicle after it has disappeared from your rearview mirror. The same goes for your right mirror. The previously described region is known as your blind zone. Although blind zones differ in severity, every vehicle has one. Unless you turn your body to look over your left shoulder, you cannot see an approaching vehicle in this spot.
How do you know if you have now set your mirrors correctly? Try this simple test: While driving in the right lane, watch an approaching car in the left lane through your rearview mirror. When it is no longer visible in your rearview mirror, it should appear in your left mirror. If it is not visible in your left mirror, you need to adjust it outward until it is even with you left rear fender. At that point, you should be able to view it by looking over your left shoulder.
Remember, each time the seat is adjusted for another driver, the side mirrors need to be adjusted accordingly!
