No, you can refuse to take a breath test. However, if you refuse, your license may be temporarily suspended. But if you do take a Breathalyzer test and you blow over the legal limit, your license will be suspended anyway. In Florida, if you refuse a breath test for the second time, you could create a separate charge for criminal refusal. However, the decision to take the breath test or not really depends on the individual circumstances of your case, and it is best to ask to confer with an attorney prior to making this decision if you are able to do so.
