Maryland Interlock Device Guidelines

In Maryland, an ignition interlock device may be required depending on the case and jurisdiction. Maryland also has an implied consent law, meaning refusing a breathalyzer, blood, or urine test automatically results in a 270-day suspension if convicted.

First Conviction
You are required to keep the ignition interlock device installed on your vehicle from 6 months to a full year.

Second Conviction
You are required to keep the ignition interlock device installed for at least 12 months.

Third and Subsequent Convictions
You are required to keep the ignition interlock device installed for a minimum of 24 months.
