Glossary
Administering authority: the court, driver
licensing, or other government department
that is responsible for administration of the
alcohol interlock program.
Alcohol interlock: a device that controls the
operation of the vehicle in relation to the BAC
of the driver.
Accepted breath sample: a forced expiration
of breath into the device fulfilling the
requirements of pressure and flow.
BAC: blood alcohol concentration.
BAC limit: a limit for blood alcohol
concentration set by the administering
authority, at or above which a fail breath test
will be registered.
Circumvention: an attempt to bypass an
alcohol interlock, whether by providing
samples other than the natural unfiltered
breath of the driver, starting the vehicle engine
without using the ignition switch, or any other
act intended to start the vehicle without first
providing an accepted breath sample.
Electronic Control Unit (ECU): part of the
ALCOLOCK device, connected with the vehicle
power and control circuits and to the handset.
Fail breath test: an accepted breath sample
with a blood alcohol concentration at or above
the BAC limit.
Handset: part of the ALCOLOCK device that
is used to conduct breath alcohol tests and
communicate with the driver.
Lockout: an event which causes the device
to prompt the participant to return the vehicle
to the service centre within a prescribed
period of time to perform a violation reset on
the alcohol interlock device.
Missed breath test: the absence of an
accepted breath sample within the breath test
time interval.
Participant: the driver who is participating in
the program subject to the conditions of the
administering authority.
PASS breath test: an accepted breath
sample with a blood alcohol concentration
below the BAC limit.
Program: the requirement to operate only a
vehicle equipped with an approved alcohol
interlock device during a period of driver
licence restriction including monitoring and
compliance with conditions.
Recall (immediate or early): a condition
entered by the alcohol interlock. The device
must be reset at an authorized service centre
before the set date or the device will enter
a permanent lockout. Recalls arise from
program violations or service matters.
Retest: additional breath tests that are
requested at random time intervals after
starting the engine and while the vehicle is in
operation.
Service: the installation, periodic monitoring,
violation reset, calibration, data retrieval and
removal of the alcohol interlock.
Service centre: a facility that provides
program services for participants, including:
training of participants, installation,
monitoring, calibration and removal of the
device.
Service provider: Affordable Interlock
Systems, as authorized by ACS to provide
program services to participants.
Tampering: an unauthorized change to, or
interference with, the function of the alcohol
interlock or its installation in the vehicle.
Program violation: events designated by
the administering authority, such as FAIL
breath tests, missed or FAIL retests, failure
to observe the scheduled monitoring service
appointment, and starting the engine without
first providing an accepted breath sample with
a PASS result.
Stand-by: a device feature that allows
commercial vehicles to leave the vehicle idling
for a period of time without a retest request.
Warm-up: a device feature that allows the
user to warm-up the vehicle for a period of
time after providing a pass breath test without
a retest request.
