Over 600,000 accidents occur each year in the US due to drivers changing lanes without seeing other vehicles. Positioning side mirrors at a 90 degree angle rather than facing the side of the vehicle reduces blind spots and improves visibility of nearby cars. With the side mirrors angled outward, drivers will be able to see other vehicles faster and for longer periods of time, reducing the risk of accidents when changing lanes. Good visibility enabled by properly positioned mirrors can help drivers avoid accidents.
