Good visual search habits require proper positioning and use of mirrors located inside and outside a vehicle. Using the settings below, you can see what is directly behind your vehicle with the inside mirror, and you can see directly into spaces adjacent to each of the vehicle’s rear corners by using the side mirrors. Mirrors are intended for detection and not for gathering detailed information.
The inside mirror
With these settings, you will have almost seamless visual contact around your vehicle, which can help you detect the presence of nearby roadway users. For example, when being passed by a vehicle in the lane to your left, you will see it progress from the rearview mirror, to the left side mirror and then to your side vision.
Before driving with these updated mirror settings, see how they work while your vehicle is parked. For example, you can parallel park along a street, then see how passing vehicles move through your mirrors and peripheral vision. This can help you become oriented to the new settings before heading out into traffic.
Remember, even properly adjusted mirrors cannot eliminate all blind spots. To reduce risk, make a final check to the sides before attempting any lateral moves.
