The Forensic Tests for Alcohol Branch developed and implemented the state's first Breath Alcohol Testing (BAT) Mobile Unit Program in 1996. The BAT Program utilizes six 32' buses equipped for processing impaired drivers at Driving While Impaired (DWI) Checkpoints. The BAT Mobile Units display logos of "Booze It & Lose It,” “Don't Drink & Drive” and “0.08 It's The Law".

The BAT Program in conjunction with law enforcement agencies conducts Driving While Impaired (DWI) Checkpoints across the state. The primary purpose of a DWI Checkpoint is to detect and apprehend the impaired driver. DWI Checkpoints maximize the deterrent effect and increase the perception of "risk of apprehension" of motorists who would operate a vehicle while impaired by alcohol or drugs. Drivers who drink too much believe that they stand little chance of being detected and arrested. The BAT Mobile Unit increases the threat of detection by allowing law enforcement to conduct DWI Checkpoints in rural areas where the drinking driver least expects to encounter law enforcement officers.
