The MGM National Harbor complex sits on the Potomac River in Oxon Hill, just south of the Beltway and the Wilson Bridge approach. The casino, hotel, restaurants, and entertainment venues draw patrons from across the region, and the late hours produce drives home that occur after midnight, after a long evening of consumption, often with the driver tired in addition to anything else.

This article walks through how MGM National Harbor DUI cases typically unfold and where the defense usually finds traction. For the broader DUI and traffic framework, see our complete Prince George’s County DUI and traffic defense guide.

The Stop Patterns

DUI stops associated with MGM rarely happen at the casino itself. Casino security and the National Harbor private security operate separately from public law enforcement, and the casino has its own set of internal procedures for handling intoxicated patrons (typically refusing further service, offering rideshare or hotel rooms, and contacting next of kin). Public DUI enforcement begins once the patron leaves the casino property and enters the public roadway.

The most common stop locations are the southbound and northbound stretches of MD 210 (Indian Head Highway) leading away from the National Harbor exit, the connecting roads through Oxon Hill (Oxon Hill Road, Livingston Road), and the approaches to the Beltway via I-295 and the Wilson Bridge. The Prince George’s County Police Department patrols these areas, the Maryland State Police covers the Beltway connections, and Maryland Transportation Authority Police covers the Wilson Bridge approach.

Stops typically begin with a traffic violation observed by a patrol officer: weaving, lane departure, speeding, equipment violations, or driving without headlights. The officer initiates the stop, observes for indicators of impairment, and proceeds with the standard DUI investigation pattern. By the time the driver reaches a stop scene, the comp records, the receipt trail, and the surveillance footage from the casino are no longer available to the officer at the roadside, but they become discoverable later in the case.

The Casino Evidence Trail

MGM National Harbor maintains extensive records of patron activity. The records become discoverable in DUI cases when the State decides to subpoena them, although in practice this is more common in cases involving aggravating factors (high BAC, crash, repeat offense, vehicular injury) than in routine first offense cases. Defense counsel sometimes finds it useful to review these records as well, both to develop a defense narrative and to anticipate the State’s evidence.

Comp and player tracking records. Patrons using player cards generate a detailed log of time at machines, time at tables, dollar volume of play, and complimentary services received (including drinks). The records establish the patron’s location and activity timeline.

Beverage service records. Cocktail service on the casino floor is tracked through point of sale systems. Records show what was ordered, when, and at which station. Restaurant and bar receipts add to the timeline.

Surveillance video. The casino maintains comprehensive surveillance coverage of public areas. Patrons can typically be tracked from arrival through departure with continuous video. The footage establishes both consumption and physical condition at departure.

Valet and rideshare logs. The valet stand and the rideshare pickup zone both maintain records that establish departure time and method. A driver who declined a rideshare offer in favor of self-driving has a record of that choice; a driver who took the valet ticket and walked to the parking garage has a different record.

The Dram Shop Question

Maryland does not have a robust dram shop liability framework comparable to some other states. The Maryland Court of Appeals declined to adopt common law dram shop liability in Warr v. JMGM Group, LLC (2013), and the General Assembly has not created broad statutory dram shop liability. The practical effect is that civil suits against MGM for over-service are difficult to maintain, although this does not affect the criminal DUI defense.

The relevance to the defense is that MGM’s incentive structure does not always align with curtailing service, and patrons who reach extreme intoxication levels at the casino may have been served well past the point where service should have stopped. Counsel sometimes uses the consumption record as mitigation evidence, particularly for first time defendants whose consumption pattern at MGM was atypical of their usual behavior.

Defense Strategy

Effective defense in MGM National Harbor DUI cases follows several patterns. First, develop the timeline carefully. The driver’s activity at the casino, the consumption pattern, and the departure circumstances all affect the defense. Second, attack the standard DUI elements: the basis for the stop, the SFST administration, the breath test procedure. Third, evaluate whether the casino records support or undermine the State’s theory of the case; selective use of the records can sometimes help the defense. Fourth, address the federal workforce consequences when applicable; many MGM patrons work for federal agencies or contractors and face administrative consequences alongside the criminal case.
