Who Qualifies for a Maryland Restricted License After a Second DUI Within 5 Years

Maryland does not issue a traditional restricted license after a second DUI within five years. Instead, the state's Ignition Interlock System Program (IISP) under Transportation Article §16-404.1 serves as the hardship pathway. You enroll in the interlock program and drive with the device installed rather than applying for a separate restricted license document. The critical window opens immediately after arrest. You have 45 days from the date of your Order of Suspension to request enrollment in the IISP before the administrative suspension takes effect. If you enroll within that window, you avoid the hard suspension period entirely and can continue driving with the interlock device installed. Miss the 45-day enrollment window and you face a longer path. The administrative suspension takes effect, and you must request a contested case hearing before the Office of Administrative Hearings (OAH) to argue for restricted driving privileges. The hearing officer has broad discretion in granting and defining restrictions, and there is no guaranteed approval.

Maryland's administrative per se law triggers an immediate suspension based on your BAC test result or refusal, separate from any criminal DUI proceedings in district or circuit court. A second offense within five years typically triggers a 180-day to 2-year administrative suspension, depending on your BAC level and whether you refused the breath test. Refusal cases face 270-day suspensions on the administrative side. BAC ≥ 0.15 triggers longer mandatory interlock periods than BAC between 0.08 and 0.14. These administrative timelines run concurrently with any criminal court-ordered suspension, but the MVA processes them independently. You have 10 days from the date of the Order of Suspension to request an MVA Office of Administrative Hearings review if you want to challenge the suspension itself. This is separate from enrolling in the IISP. Most second-offense drivers do not challenge the suspension because the interlock program offers a faster path back to legal driving than fighting the administrative case.

Maryland does not use FR-44 filings. Second DUI cases require an SR-22 certificate of financial responsibility filed by your insurance carrier with the MVA. The SR-22 filing must be active before the MVA will approve your IISP enrollment. The SR-22 filing period for a second DUI in Maryland typically runs 3 years from the date the filing is accepted, not from the date of conviction or arrest. If your SR-22 lapses at any point during that period, the MVA suspends your driving privilege immediately and you start the filing clock over. If you do not currently own a vehicle, you need a non-owner SR-22 policy. Non-owner policies provide liability coverage when you drive a vehicle you do not own and satisfy the SR-22 filing requirement for interlock program enrollment. Most carriers writing in Maryland offer non-owner policies, including Geico, Progressive, Dairyland, and The General.

The IISP does not impose the same narrow use restrictions as traditional hardship licenses in other states. Once enrolled and the device is installed, you can drive for any purpose as long as the interlock device is functioning and you comply with all monitoring requirements. You must install the interlock device in every vehicle you own or regularly operate. The device requires a breath sample before the engine starts and periodic rolling retests while driving. Failure to provide a passing sample, tampering with the device, or attempting to drive a vehicle without an interlock installed triggers program violation and immediate suspension. The MVA contracts with approved interlock vendors. Installation costs typically run $100 to $150, with monthly monitoring and calibration fees of $75 to $100. Over a 1-year interlock period, total device costs range from $1,000 to $1,350, in addition to the SR-22 premium increase and MVA fees.

If you do not enroll in the IISP within 45 days of your suspension notice, the administrative suspension takes full effect. At that point, you can request a contested case hearing before the Office of Administrative Hearings to argue for restricted driving privileges. The hearing officer evaluates your stated need for driving privileges, your compliance with court-ordered alcohol treatment or education, your SR-22 filing status, and your willingness to install an interlock device. The officer has discretion to grant restrictions limited to work, school, medical appointments, and other essential purposes, or to deny the request entirely. Approval is not automatic. The OAH process adds months to your timeline compared to enrolling in the IISP immediately after arrest. If the hearing officer denies your request, you serve the full suspension period without any restricted driving privilege.

Maryland escalates interlock requirements based on your BAC at the time of arrest. Drivers with BAC ≥ 0.15 face longer mandatory interlock periods than those with BAC between 0.08 and 0.14, per Transportation Article §16-404.1. A second offense with high BAC typically requires 1 to 2 years of interlock use before you are eligible to apply for full license reinstatement. The MVA does not remove the interlock requirement early, even if you complete all alcohol education programs or court-ordered treatment ahead of schedule. Refusal cases face similar or longer interlock periods. Refusing the breath test does not exempt you from the interlock requirement. The MVA treats refusal as an aggravating factor and imposes the same or longer device mandates as high-BAC cases.

After you complete the required interlock period, pass any required alcohol education or treatment programs, and maintain your SR-22 filing without lapse, you can apply for full license reinstatement. The base reinstatement fee is $45, but additional administrative fees may apply depending on your case. If you had multiple simultaneous suspension reasons—such as uninsured driving or failure to appear in addition to the DUI—each may carry its own reinstatement fee. The MVA will not process reinstatement until all fees are paid and all suspension reasons are resolved. You must continue the SR-22 filing for the full 3-year period even after your license is fully reinstated. Letting the SR-22 lapse at any point during that period triggers immediate suspension and restarts the filing clock.
