If this is a pre-arrest field test, you can refuse. There is no requirement to submit to this test IF you are over 21. If this is the actual breathalyzer, the DMV can certainly suspend your license for the statutory minimum of one (1) year for your first DUI and two (2) years for your second DUI. This is true whether or not you were convicted of DUI. It is also possible that the DMV can refuse to ever issue you a license again. When you receive a license, you promise to provide blood, urine or breath upon demand; this is known as implied consent. Failure to comply can lead to serious penalties.
