I was a former prosecutor for almost 10 years. I’ve been trained and certified in SFSTs, standard field sobriety testing, SFSTs, and that consists of three main tests. It’s the horizontal gaze nystagmus, the walk and turn, and the one-leg stand. They’re very actually hard to do. When you’re talking about the eye test, there are three different portions of the eye test that have to be done in order, correctly on each eye sequentially. If that order is not done correctly, the eye test can get thrown out. Same thing with the walk and turn. They’ve got to give you very specific instructions. If those instructions aren’t given to you properly, that’s not fair to you because you didn’t know what the officer was going to be looking for.
Same thing on the one-leg stand. If the officer doesn’t give you the instructions properly, it’s not fair to you that they’re going to be saying that you were intoxicated or you were less safe to drive, even though you weren’t given the instructions the right way. And so that’s why it’s so important to have someone that knows SFSTs, knows what’s going on, knows how to attack them.
