OVI charges neccesitate all of the highly trained tools most used in criminal defense law.  Defending a DWI is initiated with making sure none of your rights on the constitution are trespassed. When a cop is in direct contact with you, and they are essentially the only witnesses most of the time, their directions and MO is of the substance.  We all create accidents, and cops are no exception.  The Occasion starts when reasonable accusation that will progress to obvious cause. An example, someone gets flashed over for driving too slow at 3 am.  A cop takes reasonable suspicion that someone has created a traffic offense, swerving.  Now, when the then man begins to start visual connection or leans in closer to your automobile, law enforcement may say you posess red eyes, or there is an odor of beer. This raises the reasonable suspicion of recklessness to giving the law enforcement a clue that someone may be operating while drunk.  80% of law enforcement will say odor of whiskey, blood shot ojos, or slurred speech.  The officer will usually elaborate you were fumbling about getting your license and registration out. At this point the driver will be likely informed to get out from the auto and do universal field sobriety checks.  These are SFST’s are taught under NHTSA (National road Traffic precautionary Administration) regulations and must be followed per instruction.  when you do go through the checks, the police will make mistakes that can make the check, or tests disregarded from evidence.  Things such as physical disabilities and optimal street conditions can be integrated amoung the results of your check. (i.e. someone can’t do a walk and turn check on uneven stret). Someone will also take a breathalyzer test.  There are accidents in these machines also, and they are devices that need maintenance and specialized training on every day.  The arrest is taped from the time the law enforcement activates their sirens.  It is through this captured footage we are able to secure an factual choice on the police performing of the checks, to the accused ability taking the tests. Whether you give an OK to the tests or not, you will go to jail.
