How much does a DUI / DWI cost in Maryland?

By the DUI Cost Guide Editorial Team · Last updated: October 22, 2026

A first DUI / DWI in Maryland carries a statutory fine of Up to $1,200. This guide stacks every cost layer an official Maryland source prices — the fine, court costs, the license reinstatement fee, the DUI / DWI program, ignition interlock, and the SR-22 insurance filing — and says plainly which layers no official source prices at all.

Maryland DUI / DWI costs at a glance	Figure
Statutory fine — first DUI / DWI	Maryland's DUI statute (Transportation Article 21-902(a)) sets a first-offense fine of up to $1,200, with no stated minimum. Maryland also has a lesser offense, DWI (21-902(b)), which carries a first-offense fine of up to $500. The statute text reviewed adds no mandatory surcharge on top of the fine.
Statutory fine — second DUI / DWI	The statute separates a second offense: Up to $2,400. Second offenses also carry longer suspensions and program requirements — see the sections below.
Court costs & fees	No single statewide court-cost figure for a DUI case is published on the Maryland statute or MVA pages reviewed. Court costs are assessed by the court in the individual case.
License suspension — first offense	A first DUI conviction adds 12 points and the license may be revoked for up to 6 months. Separately, the MVA administratively suspends the license for 180 days for a first offender who fails a test with a blood alcohol concentration of 0.08 to 0.14, and for 270 days for a first test refusal.
License reinstatement fee	The MVA pages reviewed for this research do not publish a reinstatement or restoration fee amount for a DUI revocation, so no fee is listed here.
Ignition interlock	Required for all first offenders — The Maryland MVA states that participation in its Ignition Interlock Program is required for drivers convicted of DUI or DWI (including those who receive probation before judgment). The program lasts 180 days for a blood alcohol concentration of 0.08 to under 0.15, and 1 year for 0.15 or higher or a test refusal. The MVA lists a $47 enrollment fee, which may be waived for drivers receiving medical or food assistance; installation and monthly service fees are charged by the approved providers and vary, and the MVA publishes no device dollar amounts.
DUI / DWI education / treatment program	The MVA refers to an Alcohol Education Program (AEP) in connection with alcohol-related license revocations. No program fee is published on the MVA pages reviewed, so no amount is listed.
SR-22 insurance filing	No Maryland MVA page reviewed for this research states an SR-22 form filing requirement after a DUI, so SR-22 status is recorded as unverified. A DUI conviction is still likely to raise what an insurer charges, because premiums for drivers with alcohol-related convictions are set by insurers as high-risk coverage.

License suspension & reinstatement

A first DUI conviction adds 12 points and the license may be revoked for up to 6 months. Separately, the MVA administratively suspends the license for 180 days for a first offender who fails a test with a blood alcohol concentration of 0.08 to 0.14, and for 270 days for a first test refusal.

Ignition interlock

The Maryland MVA states that participation in its Ignition Interlock Program is required for drivers convicted of DUI or DWI (including those who receive probation before judgment). The program lasts 180 days for a blood alcohol concentration of 0.08 to under 0.15, and 1 year for 0.15 or higher or a test refusal. The MVA lists a $47 enrollment fee, which may be waived for drivers receiving medical or food assistance; installation and monthly service fees are charged by the approved providers and vary, and the MVA publishes no device dollar amounts.

How interlock pricing works (installation, monthly lease, calibration, removal) is in our ignition interlock cost guide.

DUI / DWI education & treatment program

The MVA refers to an Alcohol Education Program (AEP) in connection with alcohol-related license revocations. No program fee is published on the MVA pages reviewed, so no amount is listed.

SR-22 & insurance

No Maryland MVA page reviewed for this research states an SR-22 form filing requirement after a DUI, so SR-22 status is recorded as unverified. A DUI conviction is still likely to raise what an insurer charges, because premiums for drivers with alcohol-related convictions are set by insurers as high-risk coverage.

Towing, impound & other charges

The MVA's Ignition Interlock Program carries a $47 enrollment fee, which may be waived for participants receiving medical or food assistance. Note: one MVA guide page still shows a $1,000 maximum fine for a first DUI, but the current statute text (21-902) sets the maximum at $1,200, and the statute figure is the one used here.

Worked total: the verified charges stacked

Item	Cost
Statutory fine	Up to $1,200
Total of the verified state-set charges above	$0–$1,200

That total is deliberately incomplete: it leaves out everything no official Maryland source prices statewide — court costs where they are set county by county, interlock lease payments to a private vendor, towing and storage, and the insurance increase that follows an SR-22. Add your own figures for those in the cost calculator.
