Driving under the influence (DUI) laws are designed to keep roads safe by penalizing impaired driving. Many drivers assume that as long as their blood alcohol concentration (BAC) is under the legal limit-typically 0.08% in most U.S. states-they cannot be arrested or charged with DUI. However, the reality is more complex.

This article explores whether you can be arrested for DUI if you blow under the legal limit, the factors that influence DUI arrests, and what you should know to protect your rights. Whether you’re in California (ZIP 90001), Texas (ZIP 73301), Florida (ZIP 33101), or elsewhere, understanding these nuances is critical.

Understanding the Legal BAC Limit

The legal blood alcohol concentration (BAC) limit for driving in most states is 0.08% for drivers aged 21 and over. This means that if your BAC is 0.08% or higher, you are legally presumed to be impaired. For commercial drivers and drivers under 21, the limits are lower-often 0.04% and 0.00% or 0.02%, respectively.

BAC is typically measured by breathalyzer tests, blood tests, or urine tests during DUI stops.

However, it is important to note that impairment can occur at BAC levels below 0.08%.

Can You Be Arrested for DUI Below 0.08% BAC?

Yes, you can be arrested for DUI even if your BAC is below the legal limit. This is because:

• Impairment is not solely determined by BAC. Law enforcement officers can arrest you if they believe your driving ability is impaired by alcohol or drugs, regardless of your BAC.

• Field sobriety tests and officer observations play a critical role. If you fail these tests or exhibit signs of impairment, you may be arrested.

• Zero tolerance laws for underage drivers and commercial drivers mean that any detectable alcohol can lead to arrest.

• Drug-impaired driving arrests do not rely on BAC but on signs of impairment or presence of drugs.

Factors That Can Lead to DUI Arrest Despite Low BAC

1. Poor Driving Behavior

Erratic driving such as swerving, speeding, or running red lights can prompt an officer to investigate further, regardless of BAC.

2. Field Sobriety Test Performance

Failing standardized tests like the walk-and-turn, one-leg stand, or horizontal gaze nystagmus can indicate impairment.

3. Physical Signs of Impairment

Bloodshot eyes, slurred speech, the smell of alcohol or drugs, and unsteady balance can lead to arrest.

4. Presence of Drugs

If an officer suspects drug use, they may arrest you even with a low or zero BAC.

5. Prior DUI or Suspended License

Repeat offenders or those with suspended licenses may face arrest more readily.

Field Sobriety Tests and Officer Observations

Field sobriety tests (FSTs) are a key tool officers use to assess impairment. These tests are standardized but subjective and can be influenced by medical conditions, fatigue, or nervousness.

Officers also rely on their training and experience to observe signs of impairment. This means you can be arrested based on their judgment even if your BAC is below 0.08%.

Drug-Impaired Driving and DUI Arrests

DUI laws also cover impairment by drugs, including prescription medications, illegal drugs, and even some over-the-counter medicines.

• No specific BAC equivalent exists for drugs, making arrests rely heavily on officer observations and chemical tests.

• Drug Recognition Experts (DREs) may be called to evaluate suspected drug impairment.

You can be arrested for DUI with a zero BAC if impaired by drugs.

What Happens After an Arrest Under the Legal Limit?

After an arrest, you may face:

• Chemical testing: Breath, blood, or urine tests to confirm BAC or drug presence.

• License suspension: Administrative penalties may apply even if BAC is below 0.08%.

• Criminal charges: You may be charged with DUI if the officer’s evidence supports impairment.

• Court proceedings: You will have an opportunity to contest the charges.

How to Protect Your Rights if Arrested

1. Remain silent: Do not admit guilt or make incriminating statements.

2. Request an attorney immediately: Legal counsel is critical.

3. Comply with lawful orders: Refusing chemical tests may lead to additional penalties.

4. Document everything: Write down details of the stop and arrest.

5. Attend all hearings: Missing court dates can worsen your situation.
