Manual Mirrors

Vehicles with outside manual mirrors can be adjusted by moving the mirror up and down or left to right to see a little of the side of the vehicle, and have a clear view behind the vehicle.

Using hood-mounted air deflectors and add-on convex mirror attachments could decrease mirror performance.
