What Are My Rights During a Police Stop in San Antonio?

Your Core Rights During a Texas Traffic Stop

During a police stop in Texas you have three core rights: the right to remain silent beyond providing basic identification, the right to refuse consent to search your vehicle or person, and the right to an attorney once you are in custody. These rights apply whether you are stopped by SAPD, a Bexar County Sheriff’s deputy, or a DPS Trooper on IH-35 or IH-10. Knowing them before an encounter is essential — during the stop itself, there is no time to look them up.

What You Must Provide

Under Texas Transportation Code §521.025, you must provide your driver’s license, proof of insurance, and vehicle registration when requested during a traffic stop. Beyond these three items, you are not required to answer questions about where you are going, where you were, what you drank, or any other matter. You can politely state: “I am choosing to exercise my right to remain silent.”

The Right to Refuse Consent to Search

You have the right to refuse consent to a search of your vehicle or person. Politely state: “I do not consent to a search.” An SAPD officer can still conduct a search if they have probable cause or a warrant — but your refusal preserves your ability to later challenge a warrantless search as unlawful under the Fourth Amendment. Consenting waives that challenge entirely. Never consent to a search.

Field Sobriety Tests Are Voluntary

Field sobriety tests — HGN, Walk and Turn, One Leg Stand — are voluntary in Texas. You are not legally required to perform them. You can politely decline: “I am choosing not to perform field sobriety tests.” For DWI cases specifically, SFSTs are a significant source of prosecution evidence, and declining eliminates that evidence source entirely.

Miranda Rights and Custody

Miranda rights apply once you are in custody and subject to interrogation. Once arrested, clearly invoke: “I am invoking my right to remain silent. I want an attorney.” After that invocation, questioning must stop. The invocation must be clear and unambiguous under Berghuis v. Thompkins — “maybe I should talk to a lawyer” is not a sufficient invocation.

If You Believe the Stop Was Unlawful

Do not physically resist a stop you believe is unlawful. Comply, invoke your right to silence, and address the legality of the stop at the Cadena-Reeves Justice Center through a suppression motion. Physical resistance is a separate criminal charge. See our San Antonio criminal defense page.
