Can police search my car without a warrant in Texas?
In short: Sometimes. Texas officers may search a car without a warrant if they have probable cause to believe it contains evidence of a crime (Keehn v. State, Texas Court of Criminal Appeals, 2009), if you give voluntary consent, or in a few other situations. Evidence obtained in violation of the law cannot be used against you (Code of Criminal Procedure 38.23).
What are the main exceptions to the warrant requirement for a car?
- Probable cause (the automobile exception): if officers have probable cause to believe the car contains contraband or evidence, they may search it without a warrant (Carroll v. United States, 1925; Keehn v. State, 2009).
- Consent: you can say no. In Texas, the State must prove by clear and convincing evidence that consent was voluntary (State v. Ibarra, Texas Court of Criminal Appeals, 1997).
- Search incident to arrest: limited. Officers may search the passenger area only if the arrested person could reach it or it is reasonable to believe evidence of the offense of arrest is inside (Arizona v. Gant, 2009).
- Inventory: when a car is lawfully impounded, officers may inventory its contents under standard procedures.
Can they hold me for a drug dog?
Not by extending the stop without reasonable suspicion. A traffic stop may last only as long as needed to handle the traffic matter, and prolonging it for a dog sniff without reasonable suspicion violates the Fourth Amendment (Rodriguez v. United States, 2015).
What should I say?
Stay calm and do not physically resist. You can say clearly, "I do not consent to a search." Do not argue at the roadside; challenges are made later through a motion to suppress. Write down what happened as soon as you can.

Common questions
Do I have to consent to a car search in Texas?
No. You can refuse. Refusing consent does not by itself give officers probable cause.
Can police search my trunk without a warrant?
With probable cause that evidence is in the car, the automobile exception can reach any part of the car where it might be found.
What happens to evidence from an illegal search?
It cannot be used against you under Code of Criminal Procedure 38.23, and the jury can be instructed to disregard it when the facts are disputed.
