Driving under the influence (DUI) is a serious offense in Alabama, with strict laws and penalties in place to deter impaired driving. Understanding these DUI laws is crucial for all drivers in the state. This article will provide a comprehensive overview of Alabama’s DUI regulations, penalties, and related legal concepts.

Prohibited Vehicular Activity

In Alabama, it is illegal to:

  • Drive or be in actual physical control of a vehicle if:
    • The driver’s blood alcohol concentration (BAC) is 0.08% or more.
    • The driver is under the influence of alcohol, drugs, or any impairing substance to an extent that renders them incapable of safely driving a vehicle.

"Infographic titled 'In Alabama, It Is Illegal To...' showing three connected boxes. The first box states 'Drive with a BAC of 0.08% or more.' The second box states 'Drive under the influence of alcohol, drugs, or any impairing substance.' The third box states 'Be intoxicated and have an actual physical control of a vehicle.'"

Special BAC Limits

  • For commercial drivers, the BAC limit is 0.04%.
  • For drivers under 21 years old, the BAC limit is 0.02%.
  • School bus or day care drivers must not have a BAC of 0.02% or more while performing their duties.

  • License Suspension: 90 days, which can be stayed if the driver installs an ignition interlock device (IID) for six months at their own expense.
  • Substance Abuse Evaluation: Mandatory attendance and compliance with court-recommended treatments.

Second Offense (within 10 years)

  • Jail Time: 5 days to 1 year.
  • Fines: $1,100 to $5,100.
  • License Suspension: 1 year.

What Constitutes a DUI Offense in Alabama?

Understanding what constitutes a DUI offense in Alabama is essential for all drivers. The state has strict laws to deter impaired driving and ensure road safety. Here’s a detailed look at the criteria for a DUI charge in Alabama.

Key Criteria for a DUI Offense

In Alabama, you can be charged with a DUI offense if you:

  • Drive or are in actual physical control of a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher.
  • Operate a vehicle while under the influence of alcohol or drugs to a degree that renders you incapable of safely driving.

Blood Alcohol Concentration (BAC) Limits

The legal BAC limits in Alabama vary based on the type of driver:

  • Standard Drivers: 0.08% or higher.
  • Commercial Drivers: 0.04% or higher.
  • Underage Drivers (under 21 years old): 0.02% or higher.

Examples of Actual Physical Control

To better understand this concept, consider the following scenarios:

  • Scenario 1: You are sitting in the driver’s seat with the engine running and the keys in the ignition. Even if the car is parked, you can be charged with a DUI because you have the potential to drive.
  • Scenario 2: You are asleep in the backseat of your car, parked in your driveway, with the keys inside your house. In this case, it is less likely you will be charged with a DUI because you are not in a position to operate the vehicle.

DUI Enforcement in Alabama

Alabama enforces its DUI laws rigorously. Here’s what you need to know about DUI enforcement:

Implied Consent Laws

By driving in Alabama, you automatically consent to field sobriety tests and BAC testing if a law enforcement officer suspects you are intoxicated. This is known as implied consent.

Signs of Intoxication

Police officers look for several signs to determine if a driver is intoxicated, including:

  • Unsafe or Erratic Driving: Swerving, speeding, or other dangerous driving behaviors.

Understanding these factors is crucial for anyone facing DUI charges in Alabama. Here’s a detailed look at the common aggravating factors and their impact on DUI penalties.

Common Aggravating Factors

High Blood Alcohol Concentration (BAC)

  • BAC of 0.15% or Higher: If your BAC is 0.15% or higher, you face significantly harsher penalties. This is nearly twice the legal limit of 0.08%.
    • Double Minimum Penalties: The minimum penalties for a DUI are doubled. This includes fines, jail time, and the duration of the ignition interlock device (IID) requirement.
    • Mandatory Jail Time: You could face a mandatory minimum jail sentence of one year.

Refusal to Submit to a Breath Test

Implied Consent Laws in Alabama

Alabama’s implied consent laws play a crucial role in DUI enforcement. These laws are designed to encourage cooperation with law enforcement and deter drunk driving. Here’s a detailed look at what implied consent means for drivers in Alabama:

What is Implied Consent?

Implied consent in Alabama means:

  • By driving on Alabama roads, you automatically agree to submit to chemical testing if suspected of DUI.
  • This applies to all drivers, including:
    • Alabama residents
    • Out-of-state drivers
    • Licensed and unlicensed drivers

Types of Chemical Tests

Under Alabama law, you may be asked to submit to:

  • Breath tests
  • Blood tests
  • Urine tests
  • Oral fluid tests

When Can Tests Be Administered?

Chemical tests can be requested:

  • After a lawful arrest for DUI
  • When an officer has reasonable grounds to believe you were driving under the influence

Consequences of Refusing a Test

If you refuse to take a chemical test:

  • Your driver’s license will be automatically suspended for:
    • 90 days for a first refusal
    • One year for subsequent refusals within a 10-year period
  • The refusal can be used as evidence against you in court
  • You won’t be eligible for a restricted license during the suspension period

Important Points to Remember

  • You must be informed that refusing the test will result in license suspension

Implications for Your DUI Case

Refusing a test can impact your DUI case:

  • Prosecutors may argue that refusal implies guilt
  • It may be harder to challenge the officer’s observations without test results
  • You may face both the penalties for test refusal and DUI conviction

  • Right to Refuse Field Sobriety Tests: These tests are voluntary in Alabama.
  • Right to an Independent Blood Test: You can request your own blood test after submitting to the state’s test.

Potential Defenses in a DUI Case

1. Challenging the Validity of the Traffic Stop

Law enforcement must have a valid reason to pull you over. Potential arguments include:

  • Lack of Probable Cause: The officer didn’t have a legitimate reason to stop you.
  • Racial Profiling: You were targeted based on race or ethnicity.
  • Improper Checkpoint: DUI checkpoints must follow specific guidelines to be legal.

Key Points:

  • Review the police report for inconsistencies

  • Lifetime: Some states consider all prior offenses, regardless of how long ago they occurred.


  • Michigan: 7-year lookback period.
  • Florida: 5-year lookback period for second offenses, 10 years for third offenses.

Administrative License Revocation (ALR)

Many states have ALR laws, which allow for immediate license suspension upon arrest for DUI, independent of criminal proceedings:

  • Immediate Suspension: License can be suspended immediately after a failed or refused BAC test.
  • Hearing Rights: Drivers typically have the right to request a hearing to contest the suspension.


  • Texas: Immediate suspension for 90 days to 2 years, depending on the offense.
  • California: Immediate suspension for 4 months for a first offense.
