Quick answer: A DUI arrest inside the Frederick city limits is usually made by a Frederick Police Department officer and answered in the District Court of Maryland for Frederick County, which sits in the city itself. Frederick has no court and no prosecutor of its own for these charges — the State’s Attorney for Frederick County handles them. Two clocks start that night: your court date, and a 10-day MVA window no judge controls.
I’m David Waranch, and I’ve handled thousands of Maryland traffic and DUI cases, including in the Frederick County District Court. This page is about a stop inside the city. Pulled over out in the county — Urbana, Thurmont, Brunswick — start with my Frederick County DUI lawyer page.
Being released does not mean you may drive. Under Md. Code, Transp. § 21-902.1, a person arrested for a § 21-902 violation “may not drive a motor vehicle within 12 hours after the arrestee’s arrest,” and a conviction carries up to 2 months in jail or a $500 fine or both. This is the trap a downtown Frederick arrest sets: you are processed and released a few hours later, your car is sitting in a deck or a lot a few blocks away, and it is the middle of the night. Driving it home is a second criminal charge, and it is one almost nobody has heard of.
Which Frederick Courthouse Your Case Lands In
The District Court of Maryland for Frederick County sits in Frederick, so a city stop and a county stop begin in the same building. The fork comes later, and it is the prayer for jury trial.
Md. Code, Cts. & Jud. Proc. § 4-302(e) strips the District Court of jurisdiction when a defendant demands a jury trial — but only a defendant charged with an offense whose penalty “permits imprisonment for a period in excess of 90 days” is entitled to one. That line runs straight through Md. Code, Transp. § 21-902:
| Charge | Maximum, first offense | Points | Jury trial available? |
|---|---|---|---|
| DUI — § 21-902(a)(1) | 1 year and/or $1,200 | 12 | Yes — over 90 days, so the case can move to the Circuit Court for Frederick County |
| DWI — § 21-902(b)(1) | 2 months and/or $500 | 8 | No — under the threshold, so it stays in District Court |
| DUI or DWI transporting a minor | 2 years / 1 year respectively, higher fines | 12 / 8 | Yes |
| Driving within 12 hours of arrest — § 21-902.1 | 2 months and/or $500 | — | No |
Both are must-appear charges. There is no box to check and nothing you can mail in.
The request is not automatic: under § 4-302(e)(2)(ii) the judge may refuse it if the prosecutor recommends in open court that no sentence over 90 days be imposed and the judge agrees. Moving a Frederick case upstairs also buys a slower docket and a different bench. It is a tactical call, not a reflex.
Frederick Police, the Sheriff, and Where the City Line Falls
Inside the city limits the stop is usually made by a Frederick Police Department officer; outside them the same road belongs to the Frederick County Sheriff’s Office or the Maryland State Police. Venue does not change — it is a Frederick County case either way — but the arresting agency does, and that is not cosmetic.
Each agency keeps its own records on its own systems with its own retention clocks: body-worn and in-car video, dispatch logs, field notes, the certification file for whoever gave the field sobriety tests, the calibration paperwork for the breath instrument. All of it has to be asked for, from the right agency, before it cycles off.
Frederick’s boundary makes this less obvious than it sounds. The city has annexed outward in irregular pieces along US 15, MD 85 and the US 40 corridor, so a driver can cross in and out of city jurisdiction inside a mile with nothing to mark it. Your citation names the agency.
Downtown, the Golden Mile, and the Three Highways
Downtown. The historic district around North and South Market Street and the Carroll Creek corridor holds the densest concentration of restaurants and bars in the county, and the trips that end in an arrest there are short — a table to a parking deck, a turn onto Patrick or Market. Short does not mean safe: § 21-902 reaches a person who may not “drive or attempt to drive,” which is why arrests in downtown decks and lots are routine.
The commercial strips. The Golden Mile along US 40 / West Patrick Street and MD 85 / Buckeystown Pike run wide, heavily signalized and busy late. A stop here usually starts as something ordinary — a lane deviation, a light, an equipment issue — and becomes a DUI investigation at the window. Whether that first reason held up is often the strongest issue in the case.
The highways. US 15, I-70 and I-270 come together here — I-270 ends at I-70 in Frederick — making the city a through-point between Washington, Baltimore and the Pennsylvania line. Many of the drivers arrested here do not live here, and the case stays in Frederick regardless. On a DUI, which carries jail exposure, plan on coming back and appearing yourself.
If the Stop Was Not Actually in Frederick
Venue follows the stop, not your address. Because so much Frederick traffic is passing through, cases often belong elsewhere on the same corridors:
| Where you were stopped | Page |
|---|---|
| Elsewhere in Frederick County — Urbana, Thurmont, Brunswick, Walkersville, New Market | Frederick County DUI lawyer |
| East on I-70, Howard County | Ellicott City |
| Baltimore County, on the Beltway or the I-70 approach | Catonsville, Towson, Essex |
| Inside Baltimore City — its own jurisdiction, its own court and prosecutor | Baltimore City |
| South on I-270, Montgomery County | Silver Spring |
| Prince George’s County | Hyattsville, Upper Marlboro |
| Anne Arundel County | Glen Burnie |
The Second Case Nobody Sends You a Court Date For
If you blew 0.08 or more or refused the test, the officer took your Maryland license, served an order of suspension and handed you a temporary one. That case belongs to the MVA and the Office of Administrative Hearings — not to the courthouse in Frederick, and no judge here can fix it for you.
The number that matters is 10 days, not the 45 printed on the temporary license. Under Md. Code, Transp. § 16-205.1, a request inside 10 days keeps you driving until the hearing; a request on day 11 through 30 gets a hearing but does not extend the temporary license, so the suspension lands on day 46 anyway. Mechanics are on my temporary license page; what you can get back — a restricted license only at 0.08 to 0.14, never on a refusal or a 0.15 — is on my license restrictions page. Locally, see Frederick MVA hearings.
The rest of Maryland DUI law is covered in depth elsewhere on this site rather than repeated here:

| DUI or DWI — what was I actually charged with? | DUI vs. DWI in Maryland |

| Is this a second offense, and what changes? | Second and subsequent offenses |
| How much the breath number is worth | Blood alcohol concentration |
| Can I keep a conviction off my record? | PBJs in DUI cases |
One caution on the last of those, because it decides cases: Md. Code, Crim. Proc. § 6-220(f)(1) bars probation before judgment outright if within the preceding 10 years you were convicted under § 21-902 or already received a PBJ on one. Ten years, not five. If there is anything in your history, tell me on the first call.
The Charges That Ride Along With a Frederick DUI
A DUI arrest rarely arrives alone. The related charges have their own Frederick pages:
| Charge or issue | Why it comes up |
|---|---|
| Reckless driving | Frequently charged in the same stop and carries its own points and jail exposure |
| Driving while suspended | What the § 16-205.1 suspension turns into if you keep driving |
| Driving while revoked | Treated more harshly than suspension, with a longer road back |
| Driving without a license | Charged differently again where the license expired, was never issued, or is out of state |
| Driving without insurance | Court penalty plus separate MVA uninsured-motorist penalties |
| Hit and run | Added where the stop began with a collision downtown or on the strips |
| CDL violations | Federal masking rules mean a Maryland PBJ will not protect a commercial record |
| Bench warrants | What a missed Frederick court date produces, and it does not expire |
| Expungement | Clearing an eligible charge once the case is over |
| Frederick County traffic charges | Everything non-DUI, county-wide |

Common Questions
No. The City of Frederick does not run its own criminal court and does not have its own prosecutor for drunk driving charges. A DUI or DWI written by a Frederick Police Department officer is a state charge under Transp. 21-902, prosecuted by the State’s Attorney for Frederick County in the District Court of Maryland for Frederick County, which sits in the city. A stop by the Sheriff’s Office or a state trooper outside the city limits goes to exactly the same court. What the arresting agency changes is which agency holds the body camera video, the dispatch logs and the breath instrument records that the defense has to obtain.
On a DUI under Transp. 21-902(a), yes. Cts. and Jud. Proc. 4-302(e) allows a jury trial only where the penalty permits imprisonment for more than 90 days, and a first-offense DUI carries up to a year, so demanding one moves the case out of the District Court and into the Circuit Court for Frederick County. A first-offense DWI under 21-902(b) carries up to 2 months and does not qualify. There is also an exception: the District Court judge may deny the request if the prosecutor states in open court that no sentence over 90 days will be sought, the judge agrees not to impose one, and the judge agrees not to raise bond on appeal.
Not within 12 hours of the arrest. Transp. 21-902.1 makes it a separate offense for a person arrested under 21-902 to drive a motor vehicle within 12 hours after that arrest, punishable by up to 2 months in jail or a $500 fine or both. It applies whether or not the original charge is ever proven. Get a ride, and collect the car the next day.
