Immigration enforcement sometimes happens on the road — at a vehicle stop, a checkpoint, or alongside local police. Your rights in the car overlap with an ordinary traffic stop but have some immigration-specific wrinkles, especially near the border.
Driver and passengers
The driver generally must show a driver's license, registration, and insurance when lawfully stopped, as in any traffic stop under state law.
Everyone in the car has the right to remain silent about immigration status, birthplace, and how they entered the country.
No one has to consent to a search of the vehicle. You can say, "I do not consent to a search." Agents may still search if they have a legal basis, but do not consent.
Passengers can ask, "Am I free to go?" and generally do not have to answer immigration questions.
The border and the ‘100-mile zone’
Border Patrol has broader authority near the border than ICE has in the interior. At fixed checkpoints near the border, agents may briefly stop vehicles and ask about citizenship without individualized suspicion. Within roughly 100 miles of an external border, agents have some additional authority, but they still cannot search your vehicle or its closed compartments without probable cause or consent, and you still have the right to remain silent. Away from the border, ordinary Fourth Amendment rules apply more fully.
What to do
Pull over safely and keep your hands visible.
Provide license and registration if you are the driver.
Stay calm and silent beyond that; you can say you wish to remain silent and speak to a lawyer.
Do not consent to a search, and do not physically resist if they search anyway.
Never flee — it is extremely dangerous and creates new criminal exposure.
If you are a passenger with no obligation to drive, your safest course is usually to stay quiet, keep your hands visible, and ask if you are free to go. As always, do not present false documents, and do not sign anything at the roadside.

The law behind your rights
Constitutional protections apply to everyone physically present in the United States, regardless of immigration status. The Fourth Amendment limits searches and seizures and generally bars agents from entering a home without consent or a warrant signed by a judge; the Fifth Amendment protects the right to remain silent and guarantees due process; the First Amendment protects recording agents in public and sharing information; and the Fourteenth Amendment extends due-process protections. Immigration enforcement is civil, so there is a right to a lawyer, but not one provided at government expense.
These are landmark federal cases that establish the rights described above. How they apply can depend on your state, the federal circuit you are in, and the specific facts of an encounter. This is general legal information, not legal advice.
Frequently asked questions
