If you refuse to submit to a test, your suspension shall be 270 days for a first offense and two years for a second or subsequent offense.
If your test result is an alcohol concentration of at least .08 but less than .15, your suspension shall be 180 days. If the offense involves a motor vehicle accident that resulted in the death of another person, your suspension shall be six months for a first offense and one year for a second or subsequent offense.
If your test result is an alcohol concentration of .08 but less than .15, your suspension may be modified or a restricted license may be issued at a hearing.
If your test result is an alcohol concentration of .15 or more, your suspension shall be 180 days for a first offense and 270 days for a second or subsequent offense. If the offense involves a motor vehicle accident that resulted in the death of another person, your suspension shall be one year for a first offense and for a second or subsequent offense your license shall be revoked.
If you refuse a test, or take a test with a result of .15 or more, you shall be ineligible for modification of your suspension or the issuance of a restricted license, unless you participate in the ignition interlock system program under Maryland Transportation Article §16-404.1.
If you hold a commercial driver's license (CDL), and were driving a noncommercial motor vehicle when you were stopped, and you refuse to submit to a test, your CDL privilege shall be disqualified for one year for a first offense or for life if your CDL privilege has been previously disqualified for at least one year under Maryland Transportation Article §16-812(a) or (b), a federal law, or any other state's law.
If you were operating a commercial motor vehicle and your test result indicates an alcohol concentration of .04 or more, or if you refuse to submit to a test, your commercial driver's license or privilege shall be disqualified for life if your commercial driver's license has been previously disqualified for at least one year and/or you have incurred two offenses of Maryland Transportation Article §16-812 (a) or (b), a federal law, or any substantially similar offense(s) under any other state's law.
If you are convicted of a drunk or drugged driving offense under Maryland Transportation Article §21-902, and the judge or jury finds beyond a reasonable doubt that you knowingly refused to take a test breath arising out of the same circumstances, an additional criminal penalty of not more than $500 or imprisonment for not more than two months, or both, may be imposed under Maryland Transportation Article §27-101(x).
If you are convicted of a drunk or drugged driving offense under Maryland Transportation Article §21-902 (b) or (c), and the judge or jury finds beyond a reasonable doubt that you knowingly refused to take a test of breath arising out of the same circumstances, the court shall require you, under Maryland Transportation Article §27-701.1, to participate in the ignition interlock system program for one year pursuant to Maryland Transportation Article §16-404.1.
You may request an administrative hearing at any time within 30 days of the date of the Order of Suspension to show cause why your driver's license or privilege should not be suspended. You must request a hearing within 10 days of the date of the Order of Suspension to ensure that your privilege to drive is not suspended prior to your hearing. Your request for a hearing must be made in writing. You may use the "Hearing Request" form if available. Send your request to the Office of Administrative Hearings at 11101 Gilroy Road, Hunt Valley, MD 21031-1301. You must include a check or money order for $150, which is the required filing fee, made payable to the "Maryland State Treasurer." Your request for a hearing will be invalid if submitted without the required $150 filing fee or applicable fee waiver.
Your driver's license or privilege will be suspended on the 46 th day after the Order of Suspension if you do not request a hearing within 10 days of the date of the Order of Suspension or, if eligible, you do not elect within 30 days of the Order of Suspension to participate in the ignition interlock system program. In order to receive credit for the suspension, you must surrender your driver's license or certify that you no longer have the license in your possession. If you submit a valid hearing request, a suspension will not be imposed unless a decision is rendered against you, or if you fail to appear for the hearing.
Instead of requesting a hearing or upon the suspension or revocation of your driver's license, you may elect to participate in the ignition interlock system program if the following conditions are met: (1) your driver's license is not currently suspended, revoked, canceled or refused; and (2) within 30 days of the date of the Order of Suspension you (a) elect in writing to participate in the Ignition Interlock System for one year if your test resulted in an alcohol concentration of .15 or more or you refused the test or six months if your test resulted in an alcohol concentration of at least .08 but less than .15; and (b) surrender a valid Maryland driver's license or sign a statement certifying that the license is no longer in your possession. An ignition interlock election form is located on the reverse side of the driver's copy of the Order of Suspension.
