If you've been asked to provide a breath sample and you've made every attempt to provide a proper breath sample, yet you're unable to for one reason or another, you'll want to consult with an attorney because if you've been arrested for refusal and it was not really the fault of you but perhaps the fault of the machine or perhaps the fault of law enforcement, that conviction or that charge is possibly defendable. You'll want to consult with an attorney immediately to figure out what your options are.
