Reference E -- Samuel Knight vs. State of New York
Superior Court. 72 N.Y. 2d 481, 530 N.E. 2d 1273 (1988).
The court ruled that a trained operator, who properly tested
the radar, observed the traffic and checked the patrol speed
against the patrol vehicle's speedometer, can accurately
determine the speed of vehicles while the patrol vehicle is
moving.
The court affirmed the lower court's ruling and accepted
judicial notice of the radar in the moving mode of
operation.
