To establish minimum performance specifications for speed
(a) Speed detection
devices listed in the annual administrative order issued by the Commissioner of
the Department of Public Safety meet the minimum requirements and are approved.
Also sanctioned are speed detection devices from the International Association
of Chiefs of Police (hereafter "I.A.C.P.") Combined Radar and Lidar Conforming
Product List for speed measuring devices. Radars included on the I.A.C.P.
Combined Radar and Lidar Conforming Product List for speed measuring devices
must meet specifications defined in 570-7-.05,(b)1., 2., 3., and 4.
Speed detection devices listed upon the
I.A.C.P. Combined Radar and Lidar Conforming Product List for speed measuring
devices have been determined by the Department to meet the minimum performance
specifications and may be utilized provided certain modifications are present.
1. Any mechanism for automatically locking a
target speed in the display must be disabled.
2. Any mechanism for warning operators that a
display target speed exceeds a present limit, such as audible tone or momentary
locking of the display, must be disabled.
3. A minimum of two display windows for
moving mode radar so that the patrol speed and target speed may be displayed
simultaneously. Radars which have only one window may be used only in the
4. If a doppler
audio signal which gives the operator a tone signal directly correlating with
the displayed target speed is not present, it must be added.
Other Speed Timing Devices:
Speed timing devices utilizing a stopwatch
principal measure speed by dividing the distance traveled by the time it took
to travel that distance.
(I) The device shall, if
capable of measuring distance, provide visual evidence (i.e., display
calibration number) that the calibration switches are set properly; thus,
assuring the operator that the device is properly calibrated.
(II) The device, if capable of measuring
distance, must permit accurate and reliable speed checks by dialing into the
computer previously logged distances.
(III) The device shall, if capable of
measuring distance, have the capability of measuring distance in miles and of
converting distance into feet by dialing a predetermined number into the
(IV) The device must have
the capability of measuring time in increments of not more than 0.036
(V) The device shall clear
itself automatically upon the initiation of a new speed check No re-set
(VI) The device
shall allow the operator to recall time or distance if the device is capable of
measuring distance, upon the completion of a speed check without erasing the
Speed Timing devices determining speed by
measuring the time of flight of short pulses of infrared light between the
instrument and its target.
(I) The speed of light is
constant and the infrared light utilized must, when activated, transmit pulses
of infrared light to provide the operator with the true speed of the target
(II) Must provide the
user, upon command, the target vehicle's speed and distance by displaying this
information on a panel provided for this purpose.
(III) Must provide an accurate reading up to
a distance of 2000 feet with a light beam width of no more than 8
(IV) Must provide an accurate
reading when the target vehicle has been checked for a minimum of 0.3
(V) Must meet or exceed
United States Food and Drug Administration Class 1 laser eye safety
The device must
provide the following features:
III. Lighted target speed
IV. Laser transmit
indicator, either visual or audible;
V. Target light display intensity
VI. Locking device which
will maintain displayed speed of target vehicle until cleared by
VII. Power control
