Quick answer: DWI checkpoints are unconstitutional in Texas, so you should never encounter a lawful one. If you’re stopped at a roadblock-style checkpoint, stay calm and polite, provide your license and insurance if detained, and tell your attorney immediately — the stop itself may invalidate the case.

This video explains what to do if you encounter what looks like a DWI checkpoint in Texas — a state where such checkpoints are not legal. You’ll learn the difference between an unlawful sobriety checkpoint and lawful operations like driver’s license checkpoints in some circumstances, warrant roundups, or no-refusal weekends.

Most importantly: don’t argue law on the roadside. Comply calmly, say as little as possible, and let your lawyer litigate the stop — that’s where checkpoint cases are won.
