Alcohol and chemical testing

Alcohol and chemical testing supports the prosecution of drunk drivers through the provision of a systematic and standardized method of measuring the breath alcohol content of impaired motorists.

The program maintains and certifies evidential breath alcohol testing instruments, trains and certifies instrument operators and provides expert testimony in court on breath alcohol and instrumentation issues. The program is also responsible for the approval of ignition interlock devices, approval of the preliminary breath testing devices (PBTs) as well as PBT operator certification and repair.
