Q: What is squelch used for on the radio?
❖A: In devices such as two-way radios (also known as
radiotelephones), the squelch can be adjusted with a
knob, others have push buttons or a sequence of
button presses. This setting adjusts the threshold at
which signals will open (un-mute) the audio channel.
Backing off the control will turn on the audio, and the
operator will hear white noise (also called "static" or
squelch noise) if there is no signal present. The usual
operation is to adjust the control until the channel
just shuts off - then only a small threshold signal is
needed to turn on the speaker. However, if a weak
signal is annoying, the operator can adjust the
squelch to open only when stronger signals are
received.

Q: Do all ATV accidents have to be reported in Statewide
Traffic Accident Records System (STARS)?
❖A: No. However, every law enforcement officer who
investigates a vehicle accident resulting in injury to or
death of a person, or total property damage to an
apparent extent of "five hundred dollars" or more to
one person, or who otherwise prepares a written
report as a result of an investigation.
Q: What is the preferred method of measurement in a
traffic accident?
❖A: Triangulation - triangulation is the process of
determining the location of a point by measuring
angles to it from known points at either end of a fixed
baseline, rather than measuring distances to the
point directly (trilateration). The point can then be
fixed as the third point of a triangle with one known
side and two known angles.

recording time on a STARS
