How is the ALCO-SENSOR device used in DWIs?

Written by Thom Goolsby


Another type of test that the officer may use to help determine whether you have been drinking or under the influence of drugs while driving is an alco-sensor. This is what some people call the mini breathalyzer. It is a miniature hand held machine that the officers carry in their vehicle to give them a rough blood alcohol concentration reading. If, after blowing into this machine, the reading is high enough, the officer may use this result in finding probable cause to arrest you. The officer cannot, however, use this result in substitution of doing the formal Breathalyzer test downtown.
