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 preliminary breath testing devices (PBTs), PBT operator certification and approval of ignition interlock devices.
Basic Breath Examiner Specialist Training
The Chemical Test Section’s Basic Breath Examiner Specialist Training is required for local law enforcement officers seeking to perform alcohol testing using the Intoximeter EC/IR II and PBTs. Upon completion of the three-day course, successful applicants will be issued permits to conduct both evidential and preliminary breath alcohol tests.

Ignition interlock devices (IIDs)
Since mandatory IID requirements went into effect in 2010, WisDOT has received hundreds of calls and emails with questions about the program.

Installation of an ignition interlock device
Wisconsin courts are required to order an IID to be installed on every vehicle owned by the offender for first offense OWI with an alcohol concentration of 0.15 or higher, for all second or subsequent OWI offense and for chemical test refusal, unless doing so would cause an undue financial hardship.
IIDs are leased from a service provider for the duration of the vehicle sanction, a minimum of 12 months. The lease and service agreement includes fees for installation, monthly service, and removal at the conclusion of the sanction. Other fees may be assessed by the service provider for periodic calibration, violation resets, or permanent lockout conditions.
There are currently four IID models certified for use in Wisconsin. Additional information about each is available on the manufacturer’s websites:
Installation of an ignition interlock device is carried out by
service centers, that are located throughout the state. After identifying nearby service centers, the offender should call the toll-free number listed for fee information and to schedule an appointment for installation.
The installation must be completed within 14 days of a court order or customer request, whichever is later. OWI offenders who are serving a sentence in a county jail and qualify for daily work release privileges have two weeks to show proof of IID installation. Failure to show proof will result in revocation of work release privileges.
