Frequently Asked Questions - checkpoints
border checkpoints (1)
Be aware that Customs and Border Protection (CBP) agents -- which are part of the Dept. of Homeland Security (DHS) -- are permitted to search you and your belongings at the U.S. border without probable cause or a search warrant. So anytime you cross the border, you consent to a search.
CBP may generally stop and search the property of anyone entering or exiting the U.S. If agents have reasonable suspicion to believe you're concealing contraband, they may search your body using pat-down, strip, body cavity, or involuntary x-ray searches.
Checkpoints Near the Border
Be aware that DHS agents have recently set up constitutionally-questionable "security checkpoints" up to 100 miles inside U.S. territory. If you should drive into one of these roadblocks, you are not required to answer the agent's questions (usually starting with "Are you a United States citizen?"). Nor are you required to consent to any searches.

drug checkpoints (1)
No. Drug checkpoints are a trap! The Supreme Court has ruled that random checkpoints for the purpose of finding illegal drugs are unconstitutional. However, police sometimes put up signs warning drivers of up-coming drug checkpoints and instead pull over people who make illegal u-turns or discard contraband out the window. If you see a sign saying “Drug Checkpoint Ahead”, just keep driving and don’t panic. If there’s a rest area following the sign, DO NOT pull into it. If you do, you’ll find yourself surrounded by drug-sniffing dogs.
Police departments, especially in the Mid-west, have been pushing their luck with this tactic, so if you encounter anything resembling an actual drug checkpoint, please contact that state’s ACLU Chapter. Similarly, if you’re arrested as a result of a real or fake “drug checkpoint”, you must contact an attorney to explore your legal options.

DUI checkpoints (1)
Sobriety checkpoints -- also known as DUI checkpoints -- are the most common roadblocks you might encounter. They function as a general purpose investigatory tactic where police can get a close look at passing motorists by detaining them briefly. A roadblock stop is quick, but it gives police a chance to check tags and licenses, while also giving officers a quick whiff of the driver’s breath and a chance to peer into the vehicle for a moment.
Remember that your constitutional rights still apply in a roadblock situation. Though police are permitted to stop you briefly, they may not search you or your car unless they have probable cause or you agree to the search. Keep in mind that if you’re driving under the influence, your constitutional rights provide very little protection in this situation.
Since the Supreme Court’s ruling in Illinois v. Caballes police have more leeway to use drug-sniffing dogs in roadblock situations. There’s no need to waive your rights simply because dogs are present. But be advised that your legal options are limited if you're arrested as a result of a dog sniff during a roadblock.
Also keep in mind that police closely monitor cars approaching the roadblock. So you’re not likely to have any success trying to evade it.
Sobriety checkpoints are generally permitted by the courts, but only if conducted properly. If you’re arrested at a police roadblock always consult an attorney before confessing or agreeing to a plea bargain. There might be some legal options that your lawyer can pursue.
