These are the specifications from the bill: (A) can-- (i) passively monitor the performance of a driver of a motor vehicle to accurately identify whether that driver may be impaired; and (ii) prevent or limit motor vehicle operation if an impairment is detected; (B) can-- (i) passively and accurately detect whether the blood alcohol concentration of a driver of a motor vehicle is equal to or greater than the blood alcohol concentration described in section 163(a) of title 23, United States Code; and (ii) prevent or limit motor vehicle operation if a blood alcohol concentration above the legal limit is detected; or (C) is a combination of systems described in subparagraphs So breathalyzer interlocks would be a functional solution under the bill.
