DUI checkpoints in North Carolina remain constitutional under a January 2026 Court of Appeals decision that clarifies how police must conduct sobriety checkpoints and license checkpoints.

In North Carolina vs White (“State v. White”) the North Carolina Court of Appeals affirmed that a DWI checkpoint in Robeson County complied with both the Fourth Amendment and N.C.G.S. § 20-16.3A, the statute governing police checkpoints in North Carolina.

TL;DR State v. White affirms that an organized license, registration, and insurance checkpoint may pass both the primary-purpose inquiry and the Brown v. Texas reasonableness balancing when the trial court finds advance authorization, a neutral stop pattern stopping every vehicle, supervisor control limiting officer discretion, and visible law-enforcement presence. It also reaffirms that North Carolina appellate courts continue to treat marijuana odor as sufficient for probable cause to search a vehicle, notwithstanding the practical difficulty of distinguishing hemp from marijuana, and it treats the SBI hemp memorandum as nonbinding. The opinion is most vulnerable, analytically, in how it handles the written-policy requirement and how quickly it converts structural checkpoint questions into findings insulated by deference.

By unpacking how they measure alcohol, where they can fail, and how lawyers challenge their results, you’ll see why science is not necessarily as simple as a number on a printout.
