That roadside test is NOT a breathalyzer test. It’s called a “Preliminary Breath Test”. Your links all advise you have to take the breathalyzer test, and that’s true. But a breathalyzer test doesn’t happen in the field. It’s at the station attached to a very not portable machine and happens after you get arrested. Call an actual DUI lawyer yourself and ask them the difference. A PBT is not a breathalyzer test.
