I did the roadsides and thought I did fine. Why did they arrest me?

Most people think they did fine on the roadsides. Unfortunately, the police rarely agree. Part of the problem is that the police do not tell you how they are scoring you before you take these tests, so how can you know if you are passing them or even what is expected of you? On the flip side of the problem is the fact that many people investigated for DUI are in fact intoxicated and may not be accurately judging their own performance. Regardless, roadsides are very difficult for anyone to pass, even if stone-cold sober. Once police officers form a conclusion in their minds, it becomes subconsciously hard to change.
