Can I refuse to take a DataMaster DMT Breath Test?

You technically can refuse to take a breath test, but it is not advised because of Michigan’s stringent Implied Consent laws. If you refuse the DataMaster DMT test at the police station, your driver’s license will be automatically suspended for at least one year. The state levies heavy punishment for refusing the DataMaster DMT test because by driving on the roads, you have consented to the test if you are suspected of driving drunk. If you refuse to take the DataMaster DMT test, and incur the one-year license suspension, you will only have 14 days to appeal the suspension.
