Once a driver has been arrested for a DUI or DWI in Maryland by state, not federal, police, the arresting officer is required to read a form to the driver, called the DR-15 Form. This form explains the penalties for failing or refusing a breath or blood test. Of course if the driver passes the test, i.e. produces a result below .08, there is no penalty. Unfortunately, very few people have even the foggiest clue of what they will blow.
The penalty for failing the test is a 45 day suspension on a first offense or a 90 day suspension on a second or subsequent offense if the driver blows .08 or higher but less than .15. If it is a first offense within five years the driver may be eligible for work, school, medical, or alcohol education restricted driving privileges. If it is a second offense within five years the driver may only obtain a restriction allowing the driver to drive only vehicles equipped with an ignition interlock system.
If the driver blows .15 or higher the penalty is a 90 day suspension on a first offense or a 180 day suspension on a second or subsequent offense. In lieu of the suspension, the driver may be allowed to drive with an ignition interlock restriction for one year.
If the driver refuses the the penalties are a 120 day suspension for a first offense and a one year suspension for a second or subsequent offense. Again, the driver may be allowed to drive with an ignition interlock restriction for one year. A refusal may also be considered as evidence of guilt in court and may also subject the offender to an additional 60 days in jail.
