When you’re injured in a car accident caused by an impaired driver, the legal terms that appear in reports or insurance paperwork can be confusing. You may wonder about the difference between a DUI, DWI, and DWAI. To many people, these acronyms sound interchangeable. Depending on the state, they can carry different meanings and consequences.
Understanding these differences in terms can help you make sense of what happened, determine which laws apply, and identify your rights under Arizona law. Keep reading to learn more.
Understanding the Terms: DUI, DWI, and DWAI
Across the country, states use different legal terminology to describe impaired driving. Some states distinguish between DUI (Driving Under the Influence), DWI (Driving While Intoxicated), and DWAI (Driving While Ability Impaired).
In Arizona, these terms all point to the same fundamental issue: a driver operating a vehicle while impaired. The difference lies not in the name of the offense, but in the degree of impairment and the driver’s blood alcohol concentration (BAC).
What Does a DUI Mean in Arizona?
In Arizona, DUI is the main term used for impaired driving. It covers all situations where a driver’s ability to operate a vehicle safely is compromised by alcohol or drugs.
Under Arizona law, a person can be charged with DUI if they are:
- Impaired to the slightest degree by alcohol, drugs, or any combination of the two; or
- Operating a vehicle with a BAC of 0.08% or higher (0.04% for commercial drivers); or
- Driving with any amount of an illegal drug or its metabolite in their system.
From a personal injury perspective, these laws are significant because they establish a clear standard of negligence. If the at-fault driver was impaired or over the legal limit, their violation of the DUI statute can be used as evidence of negligence per se. This means negligence is presumed because they broke a safety law intended to protect others on the road.
What About DWI or DWAI?
Other states use different classifications that Arizona residents may see when researching or reading about national accident trends.
Here’s how they compare:
- DWI: Typically refers to driving with a high BAC, usually 0.08% or higher. Some states use this term interchangeably with DUI. In Arizona, what many states call a DWI would be considered a DUI.
- DWAI: This term is used in states like New York or Colorado. It applies to drivers who are impaired but have a BAC below 0.08%. Arizona does not use this term, but under its “slightest degree” impairment rule, a driver can still be held liable in both criminal and civil court. This is true even if their BAC is below the legal limit.
In short, while Arizona doesn’t label offenses as DWI or DWAI, the underlying idea is the same – any degree of impairment behind the wheel is dangerous and unlawful.
How DUI Charges Affect a Personal Injury Claim
For victims of impaired driving crashes, the difference between DUI, DWI, and DWAI matters because it can strengthen your claim for compensation.
When a driver is cited or convicted of DUI in Arizona, it serves as strong evidence that they acted negligently at the time of the crash. This can make it easier to pursue damages in a personal injury lawsuit.
Victims of DUI-related accidents may seek economic and non-economic damages, which may include:
- Medical bills and rehabilitation costs.
- Lost income and diminished earning capacity.
- Property damage.
- Pain and suffering.
- Emotional distress and trauma.
- Punitive damages, in rare cases.
Arizona law allows injury victims to recover these damages through a civil lawsuit, separate from any criminal case against the driver. Even if the at-fault driver faces jail time or license suspension, that does not automatically compensate victims. This is why working with a personal injury lawyer is important.
How a Personal Injury Lawyer Can Help
The goal of a personal injury lawyer is to help you recover full and fair compensation after being injured by an impaired driver.
Your lawyer can help by:
- Investigating the crash to uncover evidence of intoxication or impairment.
