Imagine you’re stopped by a police officer, and the officer suspects you’ve been drinking. They ask a few questions and mention they smell alcohol. The officer then reaches for a small handheld device and says, “I just need you to blow into this for me.” That device is a portable breath test, commonly called a PBT. What you decide to do can have an impact on your court case if you are charged with DUI (called ‘OVI’ in Ohio) or another alcohol-related offense.
