He should probably practice on passing the SFST first! I'll even help him cheat with the answers and still bet he fails on Saturday night!
Session 7 - Phase Three: Pre-Arrest Screening
It is in this session that you first introduce the participants to the administrative procedures for
the three SFSTs.
The first segment, "Overview: Tasks and Decisions," explains what officers should do when
employing SFSTs and preliminary breath tests (if applicable) to investigate suspected DWI
violators.
The second segment, “Gaze Nystagmus - Definition,” will describe the definition of nystagmus
and that alcohol and certain other drugs cause HGN.
The third segment, "Horizontal Gaze Nystagmus – Definition, Concept and Demonstration," and
the fourth segment, “Vertical Gaze Nystagmus – Definition, Concept and Demonstration,”
constitute the participants' initial exposure to nystagmus. You explain the phenomenon and
relate it to impairment by alcohol. You give initial demonstrations of administrative procedures
for HGN and Vertical Gaze Nystagmus (VGN). Note this is a very brief introduction to
nystagmus; the instructor is only setting the stage for Session 8.
In the fifth segment, "Divided Attention Tests: Concepts, Examples and Demonstration," you
explain the fundamental concept of divided attention and its relationship to alcohol impairment
and you give several concrete demonstrations of tests that employ the concept. The two most
important of those demonstrations focus on WAT and OLS.
In the sixth segment, "Advantages and Limitations of Preliminary Breath Testing," you will
explain the role of Preliminary Breath Testing (PBT) in the DWI Detection process. While you
need to do a thorough job in explaining how PBTs can help officers arrive at appropriate
arrest/no arrest decisions, it is important that you do not oversell this technology. PBTs need to
be presented in their proper context, i.e., something that can help corroborate officers'
observations. They must not be viewed by participants as the sole or most important basis for
the arrest decision (optional if PBTs are not allowed in your State).
The final segment is "The Arrest Decision." At this time you will briefly review all of the
evidentiary concepts covered in Sessions 5, 6, and 7 and you will stress the importance of
basing the arrest decision on all of the evidence gathered during all three phases of DWI
Detection.
