Difference Between DUI and DWI: What Drivers Should Know

Difference Between DUI and DWI in U.S. Law

The difference between DUI and DWI is a common source of confusion for drivers facing impaired driving charges. While both refer to operating a vehicle under the influence of drugs or alcohol, the meaning and severity of each term vary depending on the state. In some states, DUI and DWI are treated as distinct charges, while in others, they’re used interchangeably. Understanding the difference between DUI and DWI can help you navigate your rights and responsibilities under the law.

What “Under the Influence” Typically Refers To

One of the most common charges involves being impaired while driving, regardless of the substance. A driver may be cited for operating a vehicle while affected by:

  • Alcohol
  • Illegal drugs (e.g., marijuana, cocaine)
  • Prescription medication
  • Over-the-counter substances that impair driving

In most states, a blood alcohol concentration (BAC) of 0.08% or higher qualifies as a violation, though lower thresholds apply to underage and commercial drivers. Even without exceeding that limit, signs of impairment may still justify an arrest.

States like California and Florida often apply a single label to both alcohol- and drug-related violations.

What Is a DWI and How Is It Different?

DWI, which stands for Driving While Intoxicated or Driving While Impaired, can mean something slightly different. In states such as Texas and New York, DWI is often used to describe alcohol-related offenses specifically, often with a higher BAC than that required for a DUI.

The difference between DUI and DWI in these states may include:

  • DUI: May apply to drug impairment or low-level alcohol impairment
  • DWI: Often applies to more severe alcohol intoxication (BAC of 0.08% or higher)

Some states also use a third term, DWAI (Driving While Ability Impaired), to refer to less severe forms of impairment, typically involving a BAC between 0.05% and 0.07%.

Legal Consequences for Offenders

Regardless of how the violation is labeled, consequences are often serious and long-lasting. These may include:

  • Substantial fines
  • Temporary or permanent license suspension
  • Jail time or court supervision
  • Mandatory participation in rehabilitation or education programs
  • Ignition interlock device (IID) installation
  • Increased auto insurance premiums
  • A criminal record that follows you

For example, after a conviction, you may be required to enroll in court-ordered DUI/DWI classes or have an ignition interlock device installed on your car to prove sobriety before driving.

Repeat offenses, high BAC levels, or accidents involving injury or death can elevate a misdemeanor DUI/DWI to a felony offense, leading to even harsher consequences.

Avoiding DUI or DWI Charges

Understanding the difference between DUI and DWI helps, but prevention is the best way to avoid any charge. Here’s how to stay safe and avoid legal trouble:

  • Do not drive under the influence of alcohol or drugs
  • Use a designated driver if you plan to drink
  • Call a rideshare service (Uber, Lyft) or a taxi
  • Stay overnight if you’re too impaired to drive home
  • Use a personal breathalyzer to check your BAC
  • Read prescription labels for warnings about driving

Visit the BAC Test tool for helpful information about measuring your BAC and determining if you’re over the limit.

Know the Difference Between DUI and DWI to Stay Protected

The difference between DUI and DWI can impact how you’re charged, prosecuted, and sentenced. While both involve impaired driving, they may be treated differently based on BAC levels, the type of substance involved, and your state’s legal definitions. Whether the charge is DUI, DWI, or both, the consequences can be life-altering. Knowing the distinction helps you make informed decisions and avoid risky behavior behind the wheel.

If you’re facing either charge, seek legal guidance immediately.
