I've been charged with a dui. At the stop the policeman gave me a fst(one foot in front of the other)i'm diagnoised with arthritis in the left hip. I explained to the officer I walk with a limp and that it would be difficult to perform that test. He gave it to me anyway. Then a lady officer performed the eyetest. Then out came the portable breath test. It was .16 extreme. They took me to the station tried to do the blood draw, my blood would not come out into the needle, so they got no blood. They gave me a urine test, wrote the tickets then let me go. I've been told that the portable breath test can't be used in court, so the urine test is what they will use to prove I was drunk. I was told that the police should have either got the blood, or put me on another type of breathalizer that will tell just what my content was. What does the urine test show? Does it show my bac of .16 or does it just show I had alcohol in my system at the time they took the test? Can it be used to convict me of this crime? Please help!
