However, the most interesting response drivers in videos give to such checkpoints is, “I don’t answer questions,” which is a perfectly lawful response.

Officer: Where are you coming from?
Driver: I don’t answer questions.

Officer: Have you had anything to drink?
Driver: I don’t answer questions.

Officer: Where are you going?
Driver: I don’t answer questions.

Justia – DUI Checkpoints & Legal Requirements

Sobriety checkpoints, also called DUI checkpoints, are temporary roadblocks that law enforcement officers use to screen motorists for drunk driving-related offenses. Thirty-eight states in the country utilize sobriety checkpoints, while twelve states do not. Some states prohibit the use of sobriety checkpoints, including Texas. For states that permit the practice, the legal basis for a DUI checkpoint is typically grounded in the federal constitution in addition to the state constitution. Certain states, like Hawaii and North Carolina, have enacted statutes that explicitly provide for DUI checkpoints.

Execution of DUI Checkpoints
Generally, DUI checkpoints must be:
Planned by supervising law enforcement officials
>>> Advertised in advance <<<
Neutral toward drivers
Sufficiently safe
Clearly associated with police authority
Subject to reasonable time limits
Efficient in detaining drivers

What fools enacted these laws hampering the police from doing what they are supposed to do, spot chcks anytime, anywhere?
