Yesterday I was short with a buddy in his garage. There I drank two beers. Then I ran away right after the second beer. Like chance I was stopped 5 min later by the race management and had to blow. The first time the thing showed 0.77, then rinse out after mouth then 0.64. After waiting again then 0.58. Then they took me to the guard. Then I had to blow two times into another device which then spit out the value of 0.30, which however is taken x2, i.e. 0.6 promille. Can I proceed against it somehow, because this value was never in my blood after this short period of time. Maybe with legal protection or traffic protection (ADAC)?
