Violations &
Reporting
What Causes a Violation?
Ignoring a rolling test —
displayed as a
“MISSED TEST”
Providing a sample on an
initial or rolling test that
is not a pass — displayed
as a
“FAIL” or “VIOL”
Bypassing the device by
starting your vehicle
without providing a
passing test — displayed
as a “START VIOL”
Disconnecting the
handset unit from the
curly cord while the
engine is on
IID Terminology
Initial Test
• Initial Test pass
• Initial Test warn
• Initial Test fail
• Abort “blow harder” “blow softer”
• How is this information used?
• Look for multiple failures over a period of time (3 or more
over 15 min.) to validate CONSUMED alcohol
IID Terminology
• Rolling Retest
• Skipped rolling retest (within 5 min.)
• Retests occur within 5 to 15 min. of starting car
• Retests occur randomly thereafter
• How is this information used?
• If you have a passing breath test shortly after a skipped test and no fails before starting the car, client did not
intentionally skip the test
• Skipped retest/no subsequent tests are passed before turning engine off, client may be trying to avoid a
failed reading
• Multiple failed retests over period of 15 minutes is a serious concern – drinking and driving!
IID Terminology
• Circumvention or Illegal Start
• Interlock detected engine is running but initial test –
PASS was not provided within 4 minutes after
device detected engine run
• This requires the deliberate “bypassing” of the interlock
wiring but can be accomplished by push starting a
vehicle with manual transmission
• How is this information used?
• Look for passing test within few minutes after start violation and then look for subsequent “retest” –
PASS entries (used to check validity of circumvention)
• If no subsequent passing breath tests & engine is not off for several minutes - indication circumvention
is valid and client drove car for duration of time between circumvention and “engine off” event
IID Terminology
• Power Fail
• Source of power was lost or disconnected (low vehicle battery voltage; tampering with power to
device by disconnecting it; poor wire connection or short – detected with multiple power on/fails
in short time span; blown fuse)
• How is this information used?
• Power fails that last more than 60 minutes is cause for concern if log did not have “low battery”
events preceding the power fail entry
• If client is tampering by disconnecting device from power it usually is done more than once and
for long periods of time
• Very short power disconnects of a minute or two should not be a concern
IID Terminology
• Connected or Disconnected Head
• Not a violation or cause for concern
• Allowable for client to remove head at end of driving event and take head
unit inside
• How is this information used?
• Concern only when the head connects and disconnects and there is a pattern
after engine starts w/o a head connect shortly after
IID Terminology
• Violation Lockout
• Interlock pre-set with allowable number of violations based on state regulations
• Skips a test
• Fails a test
• Has illegal start or circumvention
• How is this information used?
• Device enters a grace period before going into final lockout
• Displayed on client’s interlock screen
• This entry does not mean client is in violation; look at all events that occurred to create lockout
condition
