It all starts with usual accusation that can progress to obvious cause. An example, you get flashed over for speeding at 4 AM.  The cop takes the usual suspicion that the driver committed a traffic offense, racing.  Now, as the police begins to make visual connection or moves in towards the vehicle, the officer will point to the fact you exhibit watery eyes, or there is an smell of alcohol. This elevates the acceptabel intuition of abnormal driving to giving the law enforcement a good idea that you may be driving while under the influence.  80% of officers will say smell of liquor, red ojos, or mumbiling talk.
