At these roadblocks, officers may check license, registration and insurance. At a crash-area roadblock, officers may not ticket for secondary offenses. That kind of roadblock needs a written, supervisor-approved plan that sets a fixed pattern for which vehicles are stopped, and the media must be told at least 48 hours ahead.

Nebraska DOT Highway Safety Office, Impaired Driving Program Assessment (June 2025); Nebraska Impaired Driving Strategic Plan
NevadaNevada law lets police set up 'administrative roadblocks' on state highways for any lawful purpose, subject to safety rules. The roadblock must be visible from at least 100 yards, have a STOP sign and a red flashing light at the entrance, and have advance warning signs set back a minimum distance. Police may also set up temporary roadblocks to catch wanted persons or deal with emergencies or hazards. The statute does not specifically mention sobriety checkpoints.

New MexicoLegal and used. Under City of Las Cruces v. Betancourt (N.M. 1987), a DWI checkpoint (sobriety checkpoint or roadblock) is valid if it is reasonable and not left to officers' unfettered discretion. The New Mexico Supreme Court set eight guidelines for judging this, including: supervisors must plan the checkpoint and approve the site and procedures, officers must follow a uniform pattern for stopping vehicles, the location and timing must be safe and reasonable, the checkpoint's official nature must be apparent, and there should be advance publicity.

Office of the Governor press release, October 24, 2026
North CarolinaLegal by statute. North Carolina law lets law enforcement agencies run 'checking stations' to check compliance with the motor vehicle laws. The agency must set the pattern for stopping vehicles in advance, operate under a written policy that gives no individual officer discretion over which vehicles are stopped, and have at least one law enforcement vehicle with its blue light on. Drivers stopped at a checking station may be asked to take an alcohol screening test if the officer determines they have been drinking. Agencies may run any type of checking station or roadblock that complies with the U.S. and North Carolina constitutions.
N.C.G.S. 20-16.3A
North DakotaLegal and used. The North Dakota Highway Patrol, often with county sheriffs, conducts announced sobriety checkpoints at predetermined locations, usually followed by saturation patrols, to deter impaired driving.

Oklahoma Highway Safety Office newsroom, May 19, 2026
OregonNot allowed. Oregon courts ruled in 1987 that police roadblocks set up to find DUII violations without individualized suspicion are an unreasonable search under the Oregon Constitution (Nelson v. Lane County; State v. Boyanovsky). Oregon's 2023 Impaired Driving Program Assessment confirms that sobriety checkpoints are not allowed under Oregon law and recommends a constitutional amendment to permit them.
Or. Const. Art. I, sec. 9; Nelson v. Lane County, 304 Or 97 (1987); State v. Boyanovsky, 304 Or 131 (1987); ODOT, Oregon Impaired Driving Program Assessment (April 2023)
PennsylvaniaLegal and used. Pennsylvania law allows police engaged in a 'systematic program of checking vehicles or drivers' to stop vehicles. Pennsylvania State Police and local agencies run DUI checkpoints, often funded by PennDOT. For example, troopers announced DUI checkpoints and increased roving patrols in Mifflin and Juniata counties in May 2026 and described a checkpoint stop as brief and routine.
75 Pa.C.S. 6308(b); PennDOT/PSP news release (2026)
Rhode IslandNot allowed. In Pimental v. Department of Transportation (R.I. 1989), the Rhode Island Supreme Court held that article 1, section 6 of the Rhode Island Constitution prohibits drunk-driving roadblocks. The Court restated this holding in State v. Sinapi.
Pimental v. Department of Transportation, 561 A.2d 1348 (R.I. 1989), as described in State v. Sinapi, Nos. 2019-388-C.A., 2019-415-C.A. (R.I.)
South CarolinaSouth Carolina law enforcement runs 'public safety checkpoints' aimed at keeping drunk and drugged drivers off the road. For example, the SC Department of Public Safety announced safety checkpoints in Spartanburg County and elsewhere on August 24, 2026, as part of the multi-state 'Hands Across the Border' event under the national Drive Sober or Get Pulled Over campaign. Separately, state law bars systematic checkpoints or roadblocks whose main purpose is to ticket seat belt violations.

TexasNot used in Texas. In Holt v. State (1994), the Texas Court of Criminal Appeals ruled that checkpoints would be unconstitutional without authorization from the Texas Legislature, and legislative attempts to authorize sobriety checkpoints have failed (per a 2006 Texas Transportation Commission minute order). A 2014 NHTSA technical assessment prepared for Texas reported that sobriety checkpoints are not used anywhere in the state.

UtahLegal with a magistrate's approval. Utah's Administrative Traffic Checkpoint Act allows a checkpoint whose primary purpose includes detecting drivers under the influence of alcohol or drugs, but only with written authority from a magistrate. A command-level officer must submit a signed written plan covering the location, date and time, which vehicles will be stopped, staffing, signs and any advance public notice. The magistrate must independently find that the plan minimizes delay, intrusion, motorist anxiety and officer discretion, and maximizes safety.
Utah Code 77-23-104
VermontLegal and used. Vermont's State Highway Safety Office lists checkpoints among its impaired-driving countermeasures. It explains that checkpoints let police briefly stop vehicles at specific, highly visible locations (all drivers or a set portion) to see if the driver is impaired, and breath tests may be given if police suspect intoxication.
