Drinking and Driving Facts | DUI vs. DWI Laws

Article Answering Frequently Asked Questions (FAQs) About the Crime of DUI-DWI

By: William C. Head, Drunk Driving Book Author Since 1991 and Veteran Atlanta DUI Attorney

This article addresses frequently asked questions about the relatively new crime of “driving under the influence.” Most crimes in America have roots dating back thousands of years but “horseless carriages” burst upon the scene in the late 1800s and became a major symbol of the Industrial Revolution. A central theme for all driving impaired statutes is “Was it safe for the person to drive?”

Difference between DUI and DWI Georgia

While every other nation on Earth has ONE law (one common “standard”) for their nation, the United States has no federal DUI law. Using federal highway funds as its “leverage,” the federal government has INFLUENCED all states to enact laws that set the adult “per se” alcohol law for being over the legal limit at 0.08 grams percent or less. In 2018, Utah became the first state to drop their adult DUI legal limit to 0.05 grams percent.

As it pertains to a DUI definition, no need existed (when the Constitution was written) to explain “what does DUI mean?” or to discuss impaired driving. Automobiles were not yet invented, and high-speed crashes on horses were not occurring at the hands of drunken settlers and cowboys.

The term “drunk driver” had never been used, so no perception of a need to define DUI as a crime existed. The Industrial Revolution changed all of that between 1870 and 1900.

From the first alcohol-related drunk driving crash, or drunk driving accident, especially those involving serious injury or death (often between a speeding car and a horse and buggy), political rumblings began for imposing laws on traffic safety. Drunk driving statistics began to be kept in Washington, D.C.

Then, since no federal law had been passed (setting a national DUI standard), the states were not preempted from enacting local drunk driving laws. In 1910, both New Mexico and New York enacted the first DWI-DUI laws to criminally sanction those who drink and drive.

Both states used the acronym “DWI,” and this acronym was the first used because ALCOHOL was the deemed culprit. Later, when more drivers had accidents and were under the influence of something OTHER than alcohol, the concept of “driving while intoxicated” and “driving while impaired” by ANYTHING began to gain favor. By 1960, driving under the influence (DUI) had become the most common term used.

How Georgia DUI Laws Were Enacted and How The Laws Evolved

England had the first news report of a fatality in an alcohol-related crash in 1904. Drunk driving stories soon became news articles in the United States and Great Britain. Our British counterparts had laws in place to interdict drunk driving before 1900.

Drunk driving is a criminal law offense in Georgia and the other 49 states. But, the state of Georgia was slow to enact its driving while intoxicated laws, relying instead on reckless driving for many years. By 1953, due to federal pressure to “fall in line” with other states and improve driving safety, the Peach State enacted new GA DUI laws that incorporated a new “implied consent law.”

Implied Consent Law in Georgia

An implied consent statute imposes a post-arrest obligation of an arrested drunk driver to either submit to a chemical test of breath, blood, or urine (to find out how much alcohol or other substance in the driver’s system) or lose driving privileges. These forensic tests could then give the government more proof of your level of impairment.

An initial BAC level of 0.15 grams percent was our state’s first alcohol “legal limit” to drink and drive in Georgia. Three times in 30 years, the BAC limit was lowered to 0.12, then 0.10 and finally to 0.08 in 2001, based on an executive order signed by then-President Bill Clinton in late 2000.

The term “drunk” is usually associated with alcohol, but every state has special laws dealing with drugged driving, operating a vehicle with any amount of marijuana in your system. Most states’ implied consent laws have been expanded to include marijuana being in your system.

Georgia DUI Law Addresses DUI-Marijuana Per Se

Once recreational marijuana use began to be enacted by local laws, these states had to set a DUI statutory limit or permissible “nanograms,” like Colorado and Washington have done for their implied consent statutes. Georgia marijuana laws are proscribed in two separate subsections of OCGA 40-6-391, in subparagraphs (a)(2) and (a)(6). So, a marijuana DUI can be from showing signs of being too impaired to drive safely, or for a blood test (collected after an arrest pursuant to the GA implied consent law) that reveals a quantity of marijuana sufficient to charge the driver with DUI marijuana “per se.” All states DWI-DUI laws make it illegal to huff volatile fumes like those from spray paint aerosol dispensers or glue, to get “high.”

Known as impaired driving, drunk driving, drugged driving, intoxicated driving, and similar phrases, modern DWI-DUI crimes focus on ingesting ANYTHING that renders a person less capable of driving safely and then getting behind the wheel. Plus, for the past 70 years or so, various states enacted laws that criminalize simply being behind the wheel WHILE having a prohibited alcohol level, a contraband (illegal substance) [e.g., PCD, crack cocaine, GHB] or a prohibited quantity of marijuana or its metabolites, or having any “controlled substance” in the person’s system.

So, the favored definition of drunk driving in America is now “DUI” instead of “DWI.” This truth is one of the more interesting drunk driving facts, especially considering that both states who passed America’s first DUI laws maintained DWI vs. DUI for more than a century.

What Is a “DUI?

The criminal laws in all states have statutes proscribing driving under the influence. Generally, this four-word phrase explains “what is DUI?” which means “driving under the influence” of alcohol, drugs, or some other substance. The Georgia Supreme Court has ruled that when a person has a prescription for medications that are a controlled substance, the level of impairment may show that he or she was rendered incapable of driving safely.

Despite different wording and phraseology, a “DUI” law can be broadly defined as legislation criminalizing impaired driving or intoxicated driving as being the act of operating or being in actual physical control of a motor vehicle while the driver’s mental or physical faculties are negatively affected by ingesting some substance, chemical, or plant material. Also associated with this type of crime, federal highway safety laws began to push for all states to take away driving privileges if a person was convicted of DUI-DWI.

The DUI meaning is always consistent, except that some state lawmakers (in the last decade) have been more liberal (and reasonable) in establishing fair limits for some illegal substances (e.g., marijuana) to allow some room for passive inhalation of smoke. Georgia weed laws are inflexible for DUI marijuana, even though university studies have shown that heavy users of marijuana and cannabis oil can test positive for extended periods. One recovery center reports that heavy weed users will have detectable traces of weed for 120 days after last consuming it.

DUI is a catch-all phrase that typically conjures up an image of a droopy-eyed, inattentive, and possibly belligerent person. Yet, a person can be arrested for drunk driving, go to trial (or plead guilty), and be convicted of drunk driving (‘driving while impaired’) while looking and acting 100 percent sober.

A person may be arrested for DUI despite their appearance of sobriety because drunken driving laws across the United States have been expanded to cover any pharmaceutical, chemical, synthetic drug, glue fumes, inhalants, etc., that has the propensity to render a person less able to operate a vehicle. Therefore, as opposed to other nations, every American jurisdiction gets to define what a DUI is, insofar as “operating,” “driving,” or “being in actual physical control.”

Virtually every state broadly defines driving while impaired as having any impairing substance in your body. Since blood circulates through the brain, where human motor functions are controlled, the legislative goal is to NOT put others in danger by having an impaired driver behind the wheel. Modern chemistry, along with foolhardy individuals willing to “test” virtually any concoction by huffing, sniffing, injecting, or smoking, can create an infinite number of compounds and products, all of which are covered in the broadly-written laws of most states.

So, “designer drugs” like bath salts, “spice,” “Molly,” or another formulation that will diminish a driver’s mental sharpness or make a persons reflexes slower, due to the quantity of that product or substance in your system at the time of driving. Another category of “substances” that is now part of most states’ DUI laws is noxious vapors or aerosols that can be inhaled or “huffed” to get high.

DUI vs. DWI – The Difference Between DUI and DWI

GA drunk driving laws

Acronyms do not change the gist of “what is DUI?” D, as set forth above, is what all states’ laws seek to prevent. The only reason DUI is so common is that most states utilize this acronym in their case law (appeals dealing with driving under the influence litigation). DWI (driving while intoxicated) is the second most commonly used acronym for driving drunk, and the most common acronym could easily have been DWI vs. DUI, in America.

This list of different acronyms (some states use two or more abbreviations) are used around the United States:







CO DWAI (lesser offense)




























NY DWAI (lesser offense)



















So, the difference between DUI and DWI is mostly semantics. The legal effect of both acronyms is to criminalize drunk driving and DUI-drugs, set up criminal laws and driver’s license suspension sanctions to punish people in an effort to stop impaired driving. Below is additional driving under the influence information that brings the ubiquitous crime into better focus.

Georgia DUI laws have statutory minimum, mandatory DUI penalties for various offenders, starting with a first offense DUI and increasing punishment dramatically for a second DUI, 3rd DUI or 4th DUI felony. The tremendous increase in DUI punishment for repeat offenders can be seen in two quick examples:

  1. A DUI first offense has 40 hours of community service, or about five eight-hour days. A 2nd DUI in GA has 30 days of community service, or about 240 hours. Plus, zero additional jail time is required, except if your post-arrest alcohol test under implied consent law was 0.08 grams percent or more from a test taken at any time within three hours of the driving ending.
  2. On a DUI-Drugs case of any type, the license suspension for a first DUI by weed case is six months. For a 2nd DUI by drugs within five years, the suspension is for three years. For any second offender, 72 hours is the absolute minimum jail time, with 12 months being the maximum.

From Simple Drunk Driving Arrests to Use of an Evidential Breath Alcohol Test for a New Type of DUI-OUI

At first, the DUI-DWI laws in America were simple. Police could smell alcohol on the driver, and most drivers (when asked), admitted to drinking some alcohol. So, the arrest process for drunk driving by alcohol was very straightforward.

Since breath alcohol test equipment was not invented until the 1930s (Drunkometer and Intoximeter were the initial devices), any forensic test would have been a blood test. Seldom did cops request a warrant in those days. No DUI attorneys were around to make legal challenges since much of our nation’s Fourth Amendment and Fifth Amendment law was made in the 1960s and 1970s.

So, most arrests for drunken driving were made on the officer’s “opinion.” Any field sobriety test given at the roadway was not based on studies or science, since no effort to standardize field sobriety testing occurred until the 1970s. Each officer would dream up and use all sorts of unproven roadside tests to support an arrest decision, and criminal defense attorneys seldom challenged the LACK of any science, to back these decisions up.

Before the 1990s, DUI Defense Lawyers Were Not a Known Criminal Law Practice Area

The legal practice specialty of DUI lawyer or DWI attorney was never considered or contemplated since drunk driving defense was usually handled by the family attorney or the only practicing lawyer in town. A DUI lawyer would have starved to death from lack of business since DUI arrests were few and far between. No random DUI checkpoints existed.

Plus, in the early days of these types of arrests, the law enforcement officer would have to see a vehicle being driven on a public roadway, versus a vehicle parked on the shoulder of the road with a sleeping driver in the vehicle. Now, merely having the ignition key (or fob) and being inside a motor vehicle while drunk is enough to trigger a DUI arrest.

Criminal defense lawyers started to pay attention to DWI-DUI arrests, once citizens began to feel that they were being singled out, in an age where many people drank alcohol and drove daily. Drunk driving accidents increased as cars and trucks became more common, and legislators started tweaking existing laws.

The United States Supreme Court has made rulings about an accused person’s “right to legal counsel,” mandating that a public defender be provided for ANY crime that carries potential jail time or probation, which applies to ALL impaired driving cases.

Can You Get a DUI on Private Property?

This question is one of the more interesting and baffling of all drunk driving facts. The United States, from our English heritage, values land ownership as a paramount right of being a citizen. Yet, when it comes to driving while impaired, these time-honored concepts have fallen to the wayside (in some states) when it comes to DUI-DWI laws. The answer to the DUI on private property question is: YES, in some states.

Ultimately, several states, like Georgia, have passed laws that forbid being “under the influence” ANYWHERE within the state, including on your private property. So, you could be at your 3,000 acre farm in south Georgia, driving your tractor to plow under the fallow fields while sipping on beer all day, and later be found (by a Department of Natural Resources officer who is patrolling for illegal hunters) passed out and slumped over on your tractor, with the engine off, and be lawfully arrested for impaired driving.

You can still be arrested despite having never left your land and posing no danger to any other person or vehicle on Earth. So, being on a farm tractor that does not ever reach any public right-of-way or highway can support a Georgia DUI. DUI arrests have been made for allegedly intoxicated operators of golf carts (electric or gas powered), riding lawn mowers, mopeds, forklifts, bulldozers, a Zamboni ice resurfacing machine inside of a building housing an ice-skating rink, and many other “vehicles” including a horse and an electric wheelchair.

What Is Aggravated DUI?

Under pressure from the federal government, which controls federal highway funds, states have had to ADD another category, called “aggravated” DUI in most states. The general theme is that drivers with high BAC levels, from alcohol readings, should be punished more harshly. Some states (like Georgia), have enacted meaningless changes to accommodate the federal authorities.

A few states, like the aggravated DUI law in West Virginia, have done what the federal authorities wanted but have not gone overboard on extra punishment. A handful of other states, like Arizona, have enacted mandatory increased jail time, loss of license implications, and draconian punishments for drivers grossly impaired, according to the convicted DUI driver’s BAC level.

If Facing a DUI, Hire the Best DWI-DUI Lawyer

This review of interesting drunk driving facts and the somewhat troubling evolution of laws from being based on common sense, safety-related criminal law to an overreaching, overly-broad enactment of illogical and invasive legislation has often been passed to satisfy MADD and other anti-drinking activists.

As laws began to become too broad and overreaching, public confidence in law-making and the perception of DUI laws being written to generate revenue took over. Many accused drivers who were unfamiliar with their legal rights and suffered the heavy-handed DUI penalties resent not knowing how little alcohol a 0.08 BAC level can create.
