re: Field sobriety tests aren't designed for you to pass.

If I recall correctly, the field studies you’re referring to allowed officers to use every tool in their arsenal short of a chemical test, and we’re still talking about high false positive rates. When it comes to SFST alone, if I further recall correctly, it was a 28% false positive rate in the… 2005? NHTSA officer training manual, before it was removed entirely from subsequent manuals.

But I promise a quick Google search will return all the results you need on the subject. SFST is just this side of fricking voodoo. Sorry
