OUTSIDE REARVIEW MIRROR REQUIREMENTS FOR PASSENGER CARS -- CURVATURE, SIZE, AND LOCATION
The convex mirror with 0.9m-1.2m (35in-47in) radius of curvature is preferable for visibility requirements. FOV on the driver's side must be such that the driver sees at least a 2.15-m(7.1ft)-wide extending horizontal plane to the rear of the driver's side of the car at the widest point, said point located 4.60m (15.1ft) behind the driver's eyes. The minimum horizontal mirror sizes were determined based upon this required FOV. As a result, using a plane mirror is not a practical way to meet the required FOV because it must be at least 250mm (9.8in) wide even mounted on a door. Using convex mirrors with a 0.9m-1.2m (35in-47in) radius of curvature is a practical way because they must be at least 120mm-144mm (4.7in-5. 7in) wide even if mounted on a fender. Outside rearview mirrors must be placed inside of the binocular fixation field, which can be performed on the right and left fenders.
