So I gave hundreds of field sobriety tests when I was a cop. You know what wasn't in the police report? The wind, the rain, the slope of the road, the flashing lights in the sign that was right in front of you. None of it shows up there, but all of it can affect the way you perform these tests. We recently did a video where a 74-year-old man was completely sober, and he told the police officer, "I've been sober for 15 years." Just to make me feel better, would you mind taking a few tests to make sure it's okay for you to drive? Well, guess what? That old sober man went to jail for DUI. So never take these field sobriety tests. That's a trick every time.
