CHAPTER
I
Sources
of
Information
Drug-impaired
driving
involves
numerous
sources
of
information
that
can
help
decide
such
a
case.
Some
of
the
information
will
only
be
avail
able
to
the
accused
whereas
others
are
in
the
control
of
the
Crown.
Much
of
the
information
will
be
quite
familiar
to
criminal
practitioners.
Police
synopsis,
notes,
witness
statements,
and
the
like
are
all
still
of
use.
Overcomplicating
matters
where
the
facts
are
apparent
on
their
face
is
a
common
mistake
by
all
parties
in
drug-impaired
driving.
Where
an
accused
is
driving
poorly,
exhibiting
motor
control
issues,
and
showing
signs
of
drug
consumption,
by
admission
or
toxicological
tests,
without
other
explanation
as
to
why
the
symptoms
of
impairment
are
present,
may
lead
to
an
inescapable
inference
of
impaired
driving
by
a
trier-of-fact
For
a
list
of
possible
disclosure
materials
that
may
be
useful
in
assessing
a
case,
see
the
appendix.
Where
drug-impaired
driving
cases
differ
is
in
the
information
that
can
be
garnered
through
the
Drug
Recognition
Evaluations
(DRE)
and
toxicological
testing.
A
proper
understanding
of
what
is
involved
in
the
testing
is
reviewed
later
in
this
chapter.
Two
steps
must
also
be
com
pleted:
(i)
seeing
how
the
client
performs
on
the
evaluations
as
against
expectations
of
a
sober
individual;
and
(2)
seeing
how
the
DRE
officer
conducted
the
evaluations
as
against
their
training.
The
DRE
officer
is
required
to
complete
a
number
of
different
reports
when
testing
a
subject.
The
first,
and
arguably
most
important,
of
these
