In Texas, being arrested for a DWI (Driving While Intoxicated) doesn’t require failing a breath test. Many people believe that the only way an officer can arrest them is if they blow over the legal limit of 0.08% blood alcohol concentration (BAC). But the truth is, Texas law allows officers to arrest you even if you haven’t taken a breath test—or if your BAC is below the legal limit.

As a criminal defense law firm serving East Texas, The Law Office of Alex Tyra, P.C. often works with clients who are surprised to find themselves arrested for DWI under these exact circumstances. Understanding the legal process, your rights, and your defense options is critical when facing these charges.

Understanding Texas DWI Law

Under Texas Penal Code § 49.04, a person commits a DWI offense if they are “intoxicated while operating a motor vehicle in a public place.” Intoxication is defined in two ways:

1. Having a BAC of 0.08% or more; or

2. Not having the normal use of mental or physical faculties due to alcohol, a controlled substance, a drug, or a combination thereof.

This means that even if you refuse a breath test—or provide one and your BAC is below 0.08%—you can still be arrested based on how you appear to the officer. If an officer believes your mental or physical faculties are impaired, they can still take you into custody.

What Officers Use Instead of a Breath Test

When there’s no breath test or the results are below the limit, officers rely on subjective observations and other tools to make an arrest:

• Driving behavior: Swerving, drifting, or running red lights

• Field sobriety tests: Walk-and-turn, one-leg stand, horizontal gaze nystagmus (eye test)

• Speech and demeanor: Slurred speech, confusion, inability to answer questions

• Physical signs: Bloodshot eyes, smell of alcohol, unsteady footing

None of these alone prove guilt, but they can create what’s known as probable cause—enough reason for an officer to believe you may be driving while impaired.

Can You Be Convicted Without a Failed Breath Test?

Yes. Texas prosecutors can—and often do—pursue DWI charges without chemical test results. They build cases using:

• Officer testimony about behavior and appearance

• Dashcam or bodycam footage

• Statements made at the scene

• Field sobriety test performance

• Witness accounts

However, these cases can be challenged. Subjective observations are prone to human error, bias, and external factors like fatigue, illness, or medication.

How an Attorney Can Help

If you’ve been arrested for DWI without a failed breath test, it’s crucial to seek legal help immediately. An experienced DWI defense attorney can:

• Challenge the legality of the traffic stop or arrest

• Suppress unreliable field sobriety tests

• Cross-examine the arresting officer’s observations

• Argue that non-alcohol-related factors explain your behavior

• Fight to reduce or dismiss charges before trial

Many clients assume a DWI arrest is an automatic conviction—but it’s not. There are often valid and powerful defenses that can protect your freedom and record.
