.08 BAC

When I was college (I took police science) we did a breatholizor test. I took one shot Jack daniels and blew over the limited waited 30 mins and blew a zero.
Sounds like breathalyzer testing not actually reflecting true BAC is the problem more than the limit. That is the problem with all the numbers being thrown around here.... are they actual BAC's, or breathalyzer readings. What is the Difference Between a Breathalyzer and Blood BAC Test?
