Field sobriety tests have always been problematic. They’re pretty hard to pass stone cold sober, especially on the side of the road with the fear of going to jail if you fail. Most places you can decline and skip to the breathalyzer/ blood test, and you should if you can, even if you’re a teetotaler.
Despite being a lifelong "teetotaler" (yah,I know...boring) there's no way I'd be able to pass a roadside test.Two metal hips (balance/walking) and a chronic respiratory condition (the breathalyzer device) would see to that.
If I was ever stopped I'd demand to be taken to a hospital to have my blood drawn.And once shown to have a 0.00 level I'd demand that the hospital bill the police department.
Where do you get this info? It's always been my belief that refusal means automatic conviction.
