In almost all cases, yes. The (effective) suspension period can range from a few days to several years. Once the suspension is lifted you might be required to have an interlock device installed in your vehicle for some period of time ranging from six months to several years. The length of a suspension, of any interlock requirements, and the nature of the interlock restrictions vary based on a few situations. Refusing to give a blood, breath, or urine sample to an officer when the officer was allowed to request such a sample can lead to a longer suspension and harsher interlock requirements. A blood alcohol content (BAC) sample measuring at greater than 0.15% can lead to a longer suspension or harsher interlock requirements. The length of a suspension and interlock requirement period increases significantly if there are prior incidents on a person’s record.
