Which is why you do not give just one. The divided attention tests have between an 80 and 90% accuracy, when done with a Horizontal Gaze Nystagmus test.... not to mention the roadside Preliminary Breath Test. I can tell you in 20 years, I never had someone fail the tests and then pass the breathalyzer at the jail. Sometimes their BAC was higher than I thought it would be, but never lower.
