DUI Information - FAQ


1. What Exactly Does DUI Mean?

DUI is an abbreviation for “Driving Under the Influence.” Other abbreviations include OUI (Operating Under the Influence) and DWI (Driving Under the Influence).

They’re all definitions used when a person is operating a vehicle on a public highway and their capacity to safely operate that vehicle is impaired by the effects of drugs or alcohol.

By being so impaired, the operator is less able to control the vehicle in proximity to other vehicles, people or objects which raises the chances for a collision. Such collisions cause property damage, injury and death. To reduce these incidences, US States all have laws prohibiting DUI.



How Does a DUI Take Place?

Typically, when a police officer sees a vehicle being operated erratically they may suspect DUI may be involved.

There are several other reasons for erratic vehicle operation such as mechanical failure or driver distraction but in most cases, DUI is usually the cause.

When this happens, the police officer will usually alert the driver through the use of lights and/or sirens and attempt to make them temporarily halt vehicle operation for further investigation into the cause of the erratic activity.

At this point the officer will execute a number of standard tests to determine if DUI is indeed involved.


What Tests are Used for DUI?

A variety of tests have evolved to accurately determine if a person is committing a DUI.

In the sense of alcohol DUI, tests begin with a simple conversation and to see if a driver is slurring their speech. A flashlight in the eyes will look for redness and how the eyeballs react (jitter) when moving side-to-side. Even the aroma of alcohol on the driver’s breath may be detected.

Physical tests usually involve manual dexterity of finger touching, walking in a straight line or balancing on one foot.

As many of these tests may indicate DUI, several other factors not related to DUI may negate these tests such as a person’s physical condition, illness, or even other alcohol-like smelling substances on the breath. In these cases, a more definitive test is introduced – the chemical test.


What is a DUI Chemical Test?

Three of the most common chemical tests used to determine DUI are the breathalyzer, blood extraction and urine collection.

The goal of these three tests is to determine the concentration of alcohol itself in the bloodstream, which is called “Blood Alcohol Content” or BAC. The unit of measure for BAC is percentage.

Most States have set what’s called the “legal limit” for BAC at under 0.08. Because of the variety of circumstances involved such as age, prior driver history, and perhaps the severity of the existing incident, BAC levels as low as 0.02 may be considered in determining whether DUI has occurred or not.

What Happens When a Test for DUI Fails?

In short, refer to the “Do You Want To Know How To Beat A DUI?” section on the Home page.

At this point, the vehicle operator is considered unable to proceed any further and is then placed under arrest for DUI. This is where the officer is supposed to inform the operator of their “Miranda Rights”: …you have the right to remain silent…etc.

Typically, handcuffs are installed and the person is taken by the police to the local police station for further “processing.”  The DUI Process is underway.

After such activities as vehicle impoundment, temporary incarceration, fingerprinting, photographs, paper signings, drivers license suspension, and the “formal charge” of DUI, the person is now on their own.

In a panic, many people scramble for the first DUI attorney they can find while others procrastinate indefinitely.
