intoxilizer testing
the police officer will conduct sobriety testing to determine if an intoxilizer test is warranted. it sounds like the officer gave you a portable breath test while roadside, and when you exceeded the legal limit, you were taken to an intricate machine at the police station, which documents your breath alcohol content much like a ekg heart machine. the machine at the station is calibrated and tested often, while the roadside handheld breathtester is more like a screening tool. remember, the alcohol breath test is a tool to prove your innocence, if you ain't innocent-don't take it.
