I don't drink but what I initially learned about the DUI arrest and conviction process was so concerning I decided to do some research.
It generally seems that if you get pulled over for suspicion of DUI there is literally nothing you can do to simply drive away after the interaction.
What I've seen in my reading is the Field Sobriety Tests are difficult to pass even when sober. It is worth researching if you don't believe me. I can't say with 100 percent certainty but I think in many states the FST and the portable roadside breathalyzer tests are voluntary. The officer won't tell you that. And if you ask the officer they will likely lie to you and say they are not voluntary. Officers are legally allowed to lie to you. It is simply too risky to do these tests.
I found this quote interesting in regards to the FSTs....
"The person giving the evaluation is not medically trained. He or she only must be
high school educated (diploma or GED). College-educated registered nurses, with substantial medical training, are not trusted in the medical community to give this type of
neurological deficit lateral gaze nystagmus test. Hence, why in the world would you let an untrained individual use it and gather questionable “evidence” with which to later convict you of a crime?"

If you get pulled over for suspicion of DUI it is best to simply say I don't answer questions and I am using my 5th amendment right to remain silent. Politely refuse the FST. Politely refuse the portable roadside breathalyzer. This course of action is going to lead to an arrest and you will be taken to the station or hospital for chemical testing and your car will be impounded. Of course the chemical tests can't be refused without massive consequences to your medical and driver's license. Obviously, this process is not good, stressful, and you're going to need a lawyer. But realize it is highly unlikely that once you are pulled over for suspicion of DUI you will be free to go at any point of the interaction.
If you have some time search YouTube for falsely accused dui. It is unsettling to say the least. This is also a good read on the subject.
