Yes, from licking an envelope. It just did it today. First registered a reading of .013. I had lunch, then it registered .000. 5 hours later when I was leaving work I noticed I could still taste the glue from the envelope, but didn't think it would still register. It registered a reading of .026 and would not let the car start. I waited the three minutes and it measured .024 and would let the car start. The Intoxalock is on a family member's car. I drove it because mine was used by another family member. I haven't had a drink of alcohol in over a week. This thing cannot be trusted if something like that could result in that large a reading. I have no doubt I could repeat this procedure.
