The Fourth of July is one of the biggest travel holidays of the year, and this year’s holiday is setting new records due to this being the nation’s 250th-anniversary, and FIFA World Cup parties. This surge in Fourth of July celebrations will make roads especially crowded in Lanham, Rockville, Waldorf, Frederick, Prince George’s County, Montgomery County, Charles County, St. Mary’s County, Anne Arundel County, Calvert County, and other cities throughout Maryland. Maryland State Troopers, including members of the SPIDRE Team, arrested 108 drivers on suspicion of DUI, and issued more than 6,600 citations and warnings during July 4–6, 2025.

Where to Expect DUI Checkpoints in Maryland During Fourth of July Weekend

What Are Your Constitutional Rights at a DUI Checkpoint?
Knowing your rights if you’re stopped at a DUI checkpoint can help you avoid mistakes that could later harm your case.
Do You Have to Stop at a DUI Checkpoint in Maryland?
If you’re directed by a law enforcement officer into a DUI checkpoint in Maryland, you’re required to stop. DUI checkpoints are legal in Maryland under U.S. Supreme Court precedent, which permits brief stops for impaired-driving enforcement, and are carried out in the state under strict constitutional guidelines. Refusing to stop or attempting to flee is a separate offense and can also give police grounds to pursue you.
Maryland law requires drivers to carry a valid license, vehicle registration, and proof of insurance, and to present them upon request during a lawful traffic stop or DUI checkpoint.
Do You Have to Say Anything at a DUI Checkpoint in Maryland?
At a Maryland DUI checkpoint, drivers must stop when directed, but you have the right to remain silent and ask to speak with an attorney, decline Field Sobriety Tests (FSTs), and a roadside Preliminary Breath Test (PBT). Refusing a post-arrest chemical test in Maryland results in administrative penalties under the state’s implied consent law, separate from any criminal DUI charges. A first refusal typically leads to a 270-day license suspension, while a second or subsequent refusal generally results in a 2-year suspension.
What Should You Do if You’re Arrested at a DUI Checkpoint in Maryland?
If you’re arrested at a DUI checkpoint in Maryland, knowing the process can help you avoid escalating the situation or accidentally say anything that incriminates you.
Stay Calm
At a DUI checkpoint, officers are allowed to briefly detain drivers to check for impairment. If you’re directed to pull over:
- Stay calm and keep your hands where the officer can see them.
- Provide your license, registration, and insurance when asked.
- Be cooperative and refrain from arguing.
You Have the Right to Remain Silent
You are legally allowed to remain silent and ask to speak with an attorney before answering questions. You don’t have to explain anything to the officers. Anything you say can still be used later in court.
If You’re Arrested
If the officer arrests you for suspected DUI:
- You’ll be handcuffed and transported to a station or processing center.
- Your vehicle may be towed, depending on circumstances.
- You’ll be asked to take a chemical test (breath or blood) if you refuse to take one at the scene.
What Happens After You’re Released
After you’ve been processed on suspicion of DUI, you may be:
- Released with charges pending.
- Given a court date.
- Facing both a criminal case and licensing suspension by the Maryland Motor Vehicle Administration.
Do You Need a Lawyer If You’re Arrested for a DUI in Maryland?
If you’re arrested for DUI, you can be facing both a criminal case and an administrative license penalty by the Maryland Motor Vehicle Administration. The MVA can suspend your license right away, especially if you fail or refuse a chemical test.
