Quick answer: No — DWI checkpoints are not legal in Texas. Texas courts have held sobriety checkpoints unconstitutional without a statewide authorizing framework, and the legislature has never created one. Police must have reasonable suspicion to stop your vehicle individually.
Unlike many states, Texas does not allow DWI checkpoints. This video explains why: Texas courts require legislative authorization for suspicionless checkpoint stops, and no such law exists.
That means if you were stopped at anything resembling a roadblock or checkpoint, the legality of the stop itself is immediately in question — and evidence from an unlawful stop can be suppressed. The video also covers what police can lawfully do instead, like “no-refusal” weekend enforcement with warrants.
