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

ADMINISTRATIVE PER SE: ALCOHOL TEST FAILURES AND REFUSALS
If you are stopped by a police officer and are suspected to be under the influence, the law enforcement officer may request that you to submit to a field sobriety test or portable breath test. If you are arrested for impaired driving, the officer will advise you of your rights and provide you with an Advice of Rights form (DR-15) before requesting that you submit to a chemical blood alcohol concentration (BAC) test.
Blood alcohol concentration (BAC) is the amount of alcohol present in a 100 milliliter (mL) volume of blood. For example 80 mg is 0.08 grams, 0.08 grams of alcohol in 100 mLs is written as 0.08%. In other words, 80 mg% is equal to 0.08% which is equal to 80 mg/dL (deciliter; 100 mLs). This value can also be described as 0.08 BAC.
If you test above the legal limit for alcohol (0.08 BAC), or refuse an officer’s request to submit to a chemical test for alcohol or drug use, you will be issued an Order of Suspension (form #DR-015A) along with your traffic citation(s).
The police officer will confiscate your Maryland driver’s license and may issue you a 45-day temporary paper license.
For more information visit, see Alcohol Test Failure or Refusal.
If you were operating a commercial vehicle or are a commercial driver license holder at the time of your stop, you are also subject to the disqualification of your commercial driving status.
For more information about penalties for commercial license drivers and operators of commercial vehicles, also see the Commercial Driver’s License Manual.
VIOLATIONS OF LICENSE RESTRICTION An alcohol restriction on your license prohibits you from operating a vehicle with any level of alcohol in your blood. If you are under the age of 21, your license automatically carries “Under 21 Alcohol Restriction.” If you have a prior impaired driving offense, your license may carry an alcohol restriction on it that was placed there by the Administration or the Courts. An alcohol restriction on your license also mandates that you submit to a chemical test when an officer suspects that you may be driving under the influence. If you refuse the test, or test positive for any level of alcohol, then you will be subject to additional sanctions.
