Are DUI Checkpoints in Rhode Island Legal? No - and Here Is Why

DUI checkpoints in Rhode Island are not legal. The Rhode Island Supreme Court struck them down in Pimental v. Department of Transportation, 561 A.2d 1348 (R.I. 1989), holding that a sobriety roadblock stops every driver without probable cause or reasonable suspicion and therefore violates article I, section 6 of the Rhode Island Constitution. That decision, issued July 7, 1989, has never been overturned. It is the reason you will not see a row of officers waving every car to the shoulder on a Saturday night anywhere in the state.

One year later the United States Supreme Court went the other way in Michigan Department of State Police v. Sitz, 496 U.S. 444 (1990), and upheld sobriety checkpoints under the Fourth Amendment. Sitz changed nothing here. Pimental rests on the state constitution, and the federal Fourth Amendment sets only a floor that a state court is free to build above. Attorney Rory Munns walks clients through that history at his office at 127 Dorrance Street because it shapes how every stop in a Rhode Island DUI case gets examined. If police cannot stop you without a reason, the reason for your stop is the first thing a defense lawyer looks at.

What the Rhode Island Supreme Court Decided in Pimental

The Town of Warren police department wrote a formal roadblock program with detailed guidelines. A press release in the Providence Journal announced weekend roadblocks at several sites in Warren without giving times or locations. Late on October 10, 1986, officers set up a checkpoint on Metacom Avenue and stopped every vehicle that came through until early the next morning.

Joao Pimental was pulled over at about 1 a.m. The officer reported an odor of alcohol and bloodshot eyes, ran field sobriety tests, and asked for a chemical test. Pimental refused and was charged under § 31-27-2.1, the companion section to the DUI statute, R.I. Gen. Laws § 31-27-2. He moved to suppress everything obtained at the roadblock. An administrative judge denied the motion, the chief judge of the District Court reversed, and the state took the case up on certiorari.

Chief Justice Fay wrote for the majority. The court acknowledged that the Fourth Amendment probably permits a nondiscretionary roadblock and that the Warren program ran under strict guidelines with advance notice. None of that mattered. The court held that roadblocks set up to catch impaired drivers "operate without probable cause or reasonable suspicion and violate the Rhode Island Constitution." It called it illogical to stop fifty or a hundred vehicles on the chance that one or two drivers had broken the law, and it said no amount of control can justify a seizure made with no individualized suspicion. Two justices dissented.

Two details matter for anyone charged today. First, the court said trained officers can spot violators without stopping all traffic. Second, the case reached the Supreme Court through a motion to suppress, the same tool a defense lawyer uses now.

Why Sitz Did Not Bring Checkpoints Back

In Sitz, decided June 14, 1990, the United States Supreme Court reviewed a Michigan State Police checkpoint program. During its one operation, 126 vehicles passed through, the average delay was 25 seconds, and 2 drivers were arrested for driving under the influence. The Court held that the initial stop and brief questioning at such a checkpoint is consistent with the Fourth Amendment.

People sometimes assume a later federal ruling overrides an earlier state one. It does not work that way when the state ruling rests on the state constitution. The Pimental court said this directly: the federal constitution sets a minimum level of protection, and Rhode Island courts may impose higher standards under article I, section 6. Sitz had no power to disturb a holding grounded in Rhode Island law. The Rhode Island DUI laws that govern impaired driving still operate inside that constitutional limit today.

What Rhode Island Police Do Instead of Checkpoints

Departments across the state use three approaches that stay within Pimental.

Saturation patrols. Extra officers are concentrated in a defined area during a defined window, often bar districts late on weekend nights. Every stop still needs its own lawful basis. The patrol simply puts more eyes on the road.

High-visibility enforcement periods. Around holiday weekends and events, departments announce crackdowns and put marked cruisers where drivers will see them. An announcement is not a checkpoint, and a driver cannot be pulled over just for passing a parked cruiser.

Individual stops based on reasonable suspicion or probable cause. This is the everyday reality of a Rhode Island DUI arrest. An officer sees a specific, articulable reason to stop the car: drifting across a lane line, speeding, a rolling stop, a broken taillight, driving without headlights after dark, or an unusually slow speed. Once the car is stopped, the officer may notice signs of impairment and the investigation expands from there.

A crash scene, a road closure, or a construction detour with an officer directing traffic is not a DUI checkpoint. What Pimental forbids is stopping traffic for the purpose of screening drivers for intoxication.

What to Do If You Are Stopped at Something That Looks Like a Checkpoint

Pull over safely, turn on the interior light if it is dark, and keep your hands where the officer can see them. Hand over your license, registration, and proof of insurance when asked. You are required to produce those.

Do not argue the legality of the stop on the roadside. That argument belongs in a courtroom with the police report in hand. Instead, notice the details: the exact location, the time, whether there were signs or cones, whether every car was being stopped or only some, and what the officer said the reason for the stop was. Write it down.

You do not have to answer questions about where you were or what you drank. A polite "I would rather not answer questions" is enough. Roadside balance and eye exercises are not the chemical test covered by the implied consent law. The refusal statute, § 31-27-2.1, applies to chemical tests of breath, blood, saliva, or urine requested after arrest, and a refusal opens a separate case at the Rhode Island Traffic Tribunal at 670 New London Avenue in Cranston that can carry a license suspension of 6 months to 1 year for a first refusal. The breathalyzer refusal rules in Rhode Island deserve a careful read.

How Attorney Rory Munns Approaches These Cases

The stop is the foundation of every DUI prosecution. If the foundation cracks, the observations, the field sobriety tests, the breath result, and the statements that followed can all fall with it. So the first job is to find out exactly why the car was stopped.

Attorney Munns requests the police narrative, the dispatch logs, cruiser and body camera video, and any operational plan for that night. He compares the stated reason for the stop against the video. A lane drift that is described in the report but does not appear on camera is a problem for the state.

Where the stop lacked reasonable suspicion, the remedy is a motion to suppress filed in District Court. The motion argues that the stop was a seizure without individualized suspicion under article I, section 6 of the Rhode Island Constitution and the Fourth Amendment, and it asks the court to exclude the evidence that flowed from the stop. The prosecution then has to justify the stop through the officer, who is cross-examined on the details. Pimental is the leading authority when the stop resembled a roadblock.

The same question carries into a refusal case at the Traffic Tribunal, where § 31-27-2.1 requires the magistrate to find that the officer had reasonable grounds to believe the driver was under the influence. A stop with no lawful basis undermines that finding. Attorney Munns handles both proceedings together so the two cases do not contradict each other. As a Providence DUI lawyer with an office across from the courthouse, he is in the Sixth Division District Court most weeks and knows how these motions are heard there.

Frequently Asked Questions

Are DUI checkpoints legal in Rhode Island in 2026?

No. The Rhode Island Supreme Court held in Pimental v. Department of Transportation in 1989 that sobriety roadblocks violate article I, section 6 of the Rhode Island Constitution. That ruling has not been overturned, so police in Rhode Island do not run sobriety checkpoints.

Did the Sitz decision make checkpoints legal in Rhode Island?

No. Sitz held that checkpoints do not violate the federal Fourth Amendment. Pimental was decided under the Rhode Island Constitution, which can offer more protection than the federal floor, so the state rule survived Sitz.

What do Rhode Island police use instead of checkpoints?

Saturation patrols, announced high-visibility enforcement periods, and individual traffic stops based on reasonable suspicion or probable cause. Each stop must have its own lawful reason, such as a moving violation or an equipment defect.

Can I refuse to stop if I see what looks like a checkpoint?

Do not drive through or turn around abruptly. Stop, provide your documents, and stay polite. The legality of the stop is a question for the court, raised later through a motion to suppress.

What happens if a judge finds the stop had no reasonable suspicion?

The court can suppress the evidence obtained as a result of the stop, which may include the officer observations, field sobriety tests, chemical test results, and statements. What that means for the charge depends on what other evidence the state has, so no result can be promised in advance.

Does a bad stop also affect a chemical test refusal case?

It can. The refusal statute requires a finding that the officer had reasonable grounds to believe the driver was under the influence. A stop with no lawful basis is a strong argument against that finding at the Traffic Tribunal.
