Drug and Alcohol Testing While Out on Bond for DWI

Attorney Answer

Yes — if your bond order includes a no-alcohol or submit-to-testing condition, the court can test you at a setting, and if a judge finds you violated it, the statute does not leave the judge a choice about revoking your bond.

Start with your paperwork, because the answer is written there. Tex. Code Crim. Proc. art. 17.40(a) lets a magistrate impose any reasonable condition of bond related to the safety of a victim of the alleged offense or to the safety of the community. That general language is the authority under which no-alcohol, no-drug, and submit-to-testing conditions are commonly imposed in DWI cases. The statute itself does not name urinalysis or alcohol abstention — those are applications of the safety-condition power. So the controlling question is not what courts generally do; it is what your specific bond order says.

What happens on a positive result is where the prior advice you may have heard is too soft. Under art. 17.40(b), at a hearing limited to whether you violated such a condition, the magistrate may revoke bond only on finding by a preponderance of the evidence that the violation occurred — a lower standard than the beyond-a-reasonable-doubt standard that governs the DWI charge itself. But once the magistrate makes that finding, the statute is mandatory: the magistrate shall revoke the bond and order you immediately returned to custody. That is a separate proceeding from your DWI case and it can end with you in jail regardless of how the DWI itself eventually comes out. A court can also require increased bail under Tex. Code Crim. Proc. art. 17.09 sec. 3 where it finds the existing bond defective, excessive, or insufficient.

One point in your favour, since you say this is a first offense. Tex. Code Crim. Proc. art. 17.441 requires a magistrate to order an ignition interlock device as a bond condition only for a defendant charged with a subsequent offense under Tex. Penal Code secs. 49.04–49.06, or with intoxication assault or intoxication manslaughter, unless the magistrate finds the device would not be in the best interest of justice. A first-offense DWI is outside that article. So interlock is not something the statute forces onto your bond — and any alcohol or testing condition you do have rests on art. 17.40, not on art. 17.441.

I am not going to tell you whether you will go to jail tomorrow. That depends on facts nobody can see from here.

What you can do

1. Before your setting, read your bond conditions line by line. Look for the words alcohol, controlled substance, testing, urinalysis, portable breath test, or pretrial supervision. If none appear, there is no condition to violate. 2. If a condition does appear, comply with it. Bring proof of any required program attendance or monitoring reports with you. 3. Go to your setting. Failing to appear creates a separate and worse problem than a failed test. 4. Talk to your lawyer before the setting — not in the hallway. If you have a concern about a test result, your lawyer needs to know before you walk in, so they can address whether a hearing under art. 17.40(b) is on the docket. 5. If you do not have a lawyer, ask the court to appoint one and say so in writing before the setting rather than on the day. 6. If you cannot maintain a condition, have counsel move to modify it in advance rather than waiting to be caught out by it.

⏱ Time limits apply. The deadline most likely to have already slipped is the administrative one. A Texas DWI arrest starts a license-suspension case that runs on its own clock — roughly 15 days from the notice of suspension you were handed at arrest — and it is entirely separate from the criminal case. Since you are already out on bond, that window may have opened and closed while you were focused on the charge. Find the notice, check the date printed on it, and ask a lawyer today whether the hearing request was made. The license case and the criminal case have different standards of proof and can reach opposite results on the same stop.
