Was in a head-on collision with another vehicle, both my airbags deployed, the steering wheel bag hit me square in the face, and even now three days later, I remember most of the day, hardly any of the collision, and then the hours after. I have all the hallmark signs of a concussion, but the arresting officer used those symptom to describe me as: Confused, Unsure, Disoriented, Hesitant. During one question I hesitated as a struggled to recall what happened, but I was in pain from having been hit with the airbag. Over the next few hours my nose began to swell and airbag particles the powder would cough up. Couldn't the powder affect the breathalyzer reading?I also suffer from chronic acid reflux can that have an affect on a breathalyzer reading?
