a matte-white screen, such as a garage door. The
screen should be perpendicular both to the ground
and to the vehicle centerline.
2. The vehicle should be equipped for normal
operation. The snowplow blade should be in place
and in raised position. Below are steps listed
by the Society of Automotive Engineers (SAE)
