Jail time is a very realistic possibility after a BUI conviction, particularly for those who are not first offenders. In Florida, you may face hefty fines for committing an alcohol offense, and boating under the influence is no different. Additional fines are possible for those who refuse to submit to chemical BAC testing. Chemical tests are tests that police officers conduct to acquire samples of your physical state at the time of the BUI stop. Just like in a DUI stop, you may be subjected to a breath, blood, or urine test if you are suspected of boating under the influence. If you refuse to submit to any of these tests, you may face monetary fines for preventing the officer from collecting the samples. The prosecution may use the evidence of you refusing these tests as evidence against you in a court of law.
