Last one's just a voluntary breath sample, doesn't replace the value of any test [bell] I might ask you to take in the future. You said you had your last drink about 2 hours ago. Have you had anything to eat since then? Okay. All right. Have you ever taken one of these before? So, you're going to wrap your lips around the tube, kind of like a straw, and blow into it. Steady. Kind of as hard as you can. For as long as you can until you hear it beep once you pull it out of your mouth there. Nope, it's totally voluntary. It just gives me the best estimate of where you're actually at cuz you said you drank 2 hours ago. And so, this is the best estimate that we get of that. >> If you're willing to, go ahead and take a deep breath and go. >> Um, so what happens if I refuse a breath test? Is there any >> So, it's totally voluntary, but right now, get given how cold it is, I'm trying to determine if you're doing poorly on some aspects of the test the test because of the weather or it's because of the alcohol. And this is the only thing that's not affected by the alcohol or not affected by the weather, I'm sorry. And it's solely by any alcohol that you've consumed. So, that's why I was I was asking. >> That one is loud. >> Yep, but ultimately, it's up to you.
