Failing a breathalyzer during a traffic stop can quickly turn a routine stop into a criminal investigation. When a breath test shows alcohol levels above the legal limit, officers may believe they have enough evidence to arrest a driver for driving while intoxicated.
From there, several things may happen. A driver may be arrested, face driver’s license consequences, and later deal with criminal charges in court. The situation often moves through two separate tracks: administrative license proceedings and a criminal DWI case.
Knowing what happens after a failed breath test can help drivers understand the process and what steps may follow.
What Counts as Failing a Breathalyzer?
A breathalyzer estimates blood alcohol concentration (BAC) by measuring alcohol in a person’s breath. BAC represents the percentage of alcohol in the bloodstream.
For most adult drivers, the legal BAC limit is 0.08 percent. If a breath test result meets or exceeds this level, the driver may be considered over the legal limit.
Different limits may apply in certain situations:
- Commercial drivers: 0.04 percent
- Drivers under 21: often any measurable alcohol
- Drivers on probation for alcohol offenses: lower thresholds may apply
Breathalyzer devices work by analyzing the alcohol content in a breath sample. Since alcohol passes from the bloodstream into the lungs, the device estimates BAC from the air a person exhales.
A result above the legal limit does not automatically determine guilt, though it often becomes a key piece of evidence in a DWI case.
What Happens Immediately After You Fail a Breath Test
When a breathalyzer shows a BAC above the legal limit, the officer may move forward with an arrest for suspected DWI.
The steps that follow often look something like this:
1. Arrest at the scene
The officer may place the driver under arrest based on the breath test result and other signs of impairment.
2. Transportation to a police station or jail
The driver may be taken to a detention facility for processing.
3. Additional testing
In some cases, officers may request another breath test or a blood test to confirm alcohol levels.
4. Booking and processing
Police may record personal information, take fingerprints, and complete paperwork related to the arrest.
5. Release from custody
Depending on the situation, a driver may be released later that day or after arranging bail.
Each department follows its own procedures, so the exact steps may vary.
License Suspension After a Failed Breathalyzer
Failing a breath test may trigger driver’s license consequences through an administrative process.
This process is often separate from the criminal court case and is handled by the state’s motor vehicle authority.
Important points may include:
- License suspension may begin soon after the arrest
- A temporary driving permit may be issued for a short time
- Drivers may have a limited window to request a hearing
Administrative hearings typically review whether the officer had lawful grounds for the stop and whether the breath test result exceeded the legal limit.
If the suspension is upheld, the driver’s license may remain suspended for a set period.
Criminal Charges After a Failed Breathalyzer
A failed breathalyzer often leads to criminal charges for driving while intoxicated.
After the arrest, prosecutors review the evidence collected during the traffic stop. If they believe the evidence supports a charge, the case moves forward in criminal court.
The process may involve:
- An initial court appearance
- Pretrial hearings
- Possible negotiations between the defense and prosecution
- A trial if the case is not resolved earlier
Penalties in DWI cases can vary depending on factors such as prior offenses, BAC level, and whether the incident involved an accident.
Possible outcomes may include:
- Fines
- Probation
- Driver’s license suspension
- Alcohol education programs
- Other court-ordered conditions
Evidence Police May Use Besides the Breath Test
Breathalyzer results are important evidence in many DWI cases, though officers often collect additional information during the stop.
Other evidence may include:
- Field sobriety test results
- Driving behavior before the stop
- Officer observations, such as balance or speech patterns
- Body camera or dash camera footage
- Statements made during the encounter
When prosecutors review a case, they often consider all of this information alongside the breath test result.
Can Breathalyzer Results Be Challenged?
Breathalyzer machines must be properly maintained and used according to specific procedures. Because of this, breath test results sometimes become an issue in DWI cases.
Several factors may affect the reliability of a breath test.
Examples include:
- Whether the device was properly calibrated
- Whether testing procedures were followed
- The timing of the test after driving
- Medical conditions that may influence results
- Environmental factors at the testing location
These issues may become important when reviewing evidence in a DWI investigation.
Why Speaking With a DWI Attorney Matters
A failed breathalyzer can lead to both driver’s license consequences and criminal charges. The process that follows often involves deadlines, hearings, and court appearances.
An attorney who handles DWI cases may review the circumstances of the traffic stop, examine how the breath test was administered, and analyze the evidence collected during the investigation.
Legal guidance may also help drivers prepare for administrative hearings and understand the next steps in a criminal case.
FAQs about Failing a Breathalyzer
What BAC level fails a breathalyzer test?
For most adult drivers, a BAC of 0.08 percent or higher may be considered over the legal limit. Lower limits may apply for commercial drivers or drivers under the legal drinking age.
Can you still be charged with DWI if your BAC is below 0.08?
In some situations, drivers may still face charges if officers believe alcohol impaired their ability to drive safely.
Does failing a breathalyzer mean you will be convicted?
A failed breath test can become important evidence, though the outcome of a case depends on many factors reviewed in court.
How accurate are breathalyzer tests?
Breathalyzer devices are designed to estimate BAC. Like any measurement device, they must be maintained and used properly to produce reliable results.
Can breath test results be challenged in court?
In some cases, issues related to calibration, testing procedures, or the circumstances of the test may become part of the legal review.
What should you do after a DWI arrest?
Drivers often want to understand their legal rights and the steps involved in the process. Speaking with a qualified attorney may help clarify the situation.
