We Take the Wheel in Florida DUI Cases
Being prosecuted for Driving Under the Influence (DUI) in Florida can be an overwhelming and stressful ordeal, especially if you don’t have the assistance of an experienced Tampa DUI lawyer to guide you through the process. In pursuit of its goals of punishment and deterrence, Florida law is unforgiving with respect to impaired driving, imposing harsh penalties. Those convicted of DUI in Florida can face incarceration, probation, driver’s license suspension, vehicle impoundment, mandatory ignition interlock installation, community service, and substantial fines. When aggravating factors are present, such as prior DUI convictions or causing property damage, these penalties can be significantly more severe.
Given the severity of these consequences, retaining a skilled DUI attorney is more than simply an advantage; it’s a necessity. For over a decade, Tampa DUI lawyer William B. Wynne has represented clients in a wide range of DUI cases, including enhanced DUI, felony DUI, DUI involving drugs, DUI accidents, juvenile DUI, and more.

DUI charges are unique in the criminal justice system due to their wide-reaching impact across various segments of society. The universality of driving and the prevalence of alcohol consumption contribute to DUI’s distinctive nature as a crime that transcends socioeconomic boundaries—impacting everyone from everyday citizens to high-profile professionals like doctors, accountants, and judges.
Historically, DUI laws were more lenient. There was a time when DUI was not even a commonly prosecuted offense. However, over the years, changing societal norms and the efforts of advocacy groups like Mothers Against Drunk Driving (MADD) have played a pivotal role in influencing public opinion and legislative priorities, shedding light on the scope of the problem and pressuring government officials to enact stronger penalties and more focused law enforcement efforts regarding impaired driving.1
Despite these developments, DUI continues to be a significant issue in Florida and across the nation. In 2018 alone, approximately 32,177 people were arrested for DUI in the Florida.2 And in 2020, there were just under 30,000 DUI arrests in the state.3 Between 2009 and 2018, 7,573 people were killed in crashes involving an alcohol-impaired driver in Florida.4 In 2022, Florida saw 5,262 alcohol-only, drunk driving-related crashes, resulting in 3,084 injuries and 423 fatalities.5
Given this climate, lawmakers, responding to public concern, media attention, and the efforts of advocacy groups, have implemented harsh penalties and strict enforcement to deter DUI offenses and enhance public safety. Florida’s unforgiving approach to DUI enforcement, prosecution, and sentencing is a logical outgrowth of this political climate. The state’s strict DUI laws, with their emphasis on deterrence and punishment, reflect a political process shaped by a societal shift towards intolerance of impaired driving and a desire to protect communities from the dangers posed by drunk drivers.
A Tampa DUI lawyer can help navigate the complexities of these laws, providing valuable insight and defense for individuals facing DUI charges.
In general terms, driving under the influence (DUI) refers to operating a vehicle while impaired by alcohol or drugs. However, this straightforward definition leaves out many of the legal nuances specific to Florida law. Section 316.193, Florida Statutes sets forth the criminal offense of Driving Under the Influence in Florida. Under this statute, a person is guilty of DUI if they are “driving or in actual physical control of a vehicle” while under the influence of alcohol or drugs “to the extent that the person’s normal faculties are impaired,” or if they have a blood or breath alcohol level of 0.08% or higher. § 316.193, Fla. Stat. (2023).
Section 316.193 provides two ways of determining if a driver is impaired:
To clarify, DUI impairment under Florida law can be established either through a BAC above 0.08% or through other observational or circumstantial evidence that the driver’s normal faculties are impaired. In the context of DUI cases, evidence that the driver’s normal faculties are impaired usually consists of the arresting officer’s observations of the driver, including slurred speech, difficulty standing, the smell of alcohol emanating from the driver’s breath, poor performance on field sobriety exercises, statements made by the driver, and an erratic driving pattern.
These two methods of establishing DUI impairment operate independently. Therefore, DUI impairment can be established even if a driver has a BAC below 0.08% or refuses to take the breath test entirely, provided there is other evidence that the driver’s normal faculties are impaired. For example, a driver displaying erratic behavior, having difficulty communicating, or failing field sobriety excercises could be convicted of DUI despite a BAC below the legal limit. Conversely, impairment can be demonstrated with a BAC above 0.08%, even if there is no other evidence to show the defendant was impaired. For example, if a driver’s BAC is measured at 0.08% or higher, this alone can justify a DUI charge under Florida law, even if the driver appears to be sober in terms of driving patterns, physical appearance, and demeanor, and there is no detectable smell of alcohol.
With the advent of technology, chemical tests, such as breathalyzers, have become a common method of proving the impairment element of DUI. However, field sobriety tests and officer observations still play a significant role. Typically, both the observations of investigating officers and test results are used together in prosecuting a DUI case. This comprehensive approach combines subjective observations and objective measurements in DUI investigations.

In cases involving breath alcohol tests, Florida law establishes legal presumptions based on the driver’s BAC levels. These presumptions, as detailed in section 316.1934(2), Florida Statutes, are as follows:
These presumptions are rebuttable, meaning they can be challenged with contrary evidence. For example, if a driver has a BAC below 0.05% but there is strong evidence showing they were impaired, such as poor performance on field sobriety exercises, a staggering demeanor, and slurred speech, the presumption of non-impairment can be overcome. Conversely, if a driver has a BAC of 0.08% or higher but can present convincing evidence that they were not impaired, they might rebut the presumption of intoxication.
These presumptions of impairment play a crucial role in DUI court cases because they guide how evidence is interpreted and presented. In court, they serve as a way of assigning weight to the test results, often being included in jury instructions. For drivers, this means that while breath or blood test results are significant, they are not the sole deciding factor in their case. Other evidence, such as field sobriety tests or officer observations, can influence the outcome.
In order for a traffic stop for an infraction or a crime to be proper, the police must have a reasonable suspicion of criminal activity, or probable cause to believe a traffic infraction has been committed.” Jones v. State, 842 So. 2d 889 (Fla. 2d DCA 2003). This means that to investigate a driver for suspicion of DUI, a police officer must have a reasonable suspicion that the driver is in actual physical control of a vehicle and that they are impaired. Remember, this is simply the requirement to stop and investigate a driver, not to make an arrest. Placing a suspect under arrest for DUI requires a bit more.
Throughout the years, several court decisions have clarified what constitutes reasonable suspicion. A bare suspicion or a mere hunch is insufficient. Popple v. State, 626 So. 2d 185, 186 (Fla. 1993). In determining whether sufficient evidence to support a well-founded suspicion exists, a court should consider all facts known by police at the time of the stop. Bartlett v. State, 508 So. 2d 567, 568 (Fla. 2d DCA 1987).
Reasonable suspicion is a comparatively low standard and can be easily met if an officer observes one or more indicators of impairment—like a clumsy or erratic driving pattern, the smell of alcohol, bloodshot watery eyes, etc. In numerous Tampa DUI cases, reasonable suspicion has been established through erratic driving, slurred speech, or difficulty in communicating with officers. Often, reasonable suspicion simply gives an officer an opportunity to develop probable cause, which then allows the officer to make an arrest.
Probable cause—on the other hand—requires a little more than reasonable suspicion. Probable cause is a set of circumstances that may lead a law enforcement officer to reasonably believe that a crime has been (or is being) committed. To initiate a DUI arrest, a law enforcement officer must have probable cause to believe that the driver is committing the crime of DUI.
The Florida Supreme Court defines probable cause as “a reasonable ground of suspicion supported by circumstances sufficiently strong to warrant a cautious person in the belief that the person is guilty of the offense charged.” Dunnavant v. State, 46 So. 2d 871 (Fla. 1950). Consequently, probable cause for a DUI arrest must be based upon more than a belief that a driver has consumed alcohol; it must arise from facts and circumstances that show a probability that a driver is impaired by alcohol or has an unlawful amount of alcohol in his system. State v. Kliphouse, 771 So. 2d 16 (Fla. 4th DCA 2000).
Typically, a combination of several factors constitutes probable cause. These can include an erratic or clumsy driving pattern, the smell of alcohol, slurred speech, difficulty maintaining balance, admissions, bloodshot watery eyes, and many more. A skilled Tampa DUI lawyer can challenge the determination of probable cause or reasonable suspicion in a DUI case by filing and arguing a motion to suppress evidence, which can lead to the dismissal of charges.
For Tampa drivers facing DUI charges, it’s crucial to understand the lifelong consequences that can ensue. Even a first-time offender faces severe minimum penalties. This means that if you are unable to get the charges dropped or reduced, the judge has no choice but to sentence you to the minimum penalties.
Most DUI cases are misdemeanors and are punishable by a fine from $500.00 to $1,000.00 and can include a one-year license suspension and 6 months of imprisonment. That means jail time is possible—even on a first offense. In addition, DUI penalties include a 10-day vehicle impoundment and up to one year of probation.
If further evidence were needed of Florida’s stringent DUI laws, consider that the legislature has expressly prohibited the withholding of adjudication in DUI cases. Under section 316.656, Florida Statutes, the Florida legislature made it unlawful for a court to withhold of adjudication on a DUI offense. This means that your DUI case cannot be sealed or expunged and will stay with you for life, unless you can get it dropped, dismissed, or reduced to a lesser offense, and you are otherwise eligible to seal or expunge your record. For more details, see our expungement & sealing page. These potential long-term consequences highlight the importance of retaining an experienced Tampa DUI Lawyer.
If you’re convicted of Driving Under the Influence, even if it’s your first offense and you have no prior record, you will be facing harsh minimum sentence requirements. This means that if you’re found guilty, the judge has no choice but to sentence you to these requirements as established by law. In other words, the judge cannot lawfully give you less. As a Tampa DUI Lawyer with over 10 years of experience, William B. Wynne is very experienced in negotiating these harsh consequences.
| Penalty Type | Details |
|---|---|
| Jail Time | Up to Six Months |
| Up to Nine Months (if BAC > 0.15% or minor in the vehicle) | |
| Probation | Up to Twelve Months |
| License Suspension | 6-12 Months |
| Fines | $500 to $1,000 |
| $1,000 to $2,000 (if BAC > 0.15% or minor in the vehicle) | |
| Vehicle Impoundment | 10 days Mandatory |
| Other Penalties | 50 Hours of Community Service, DUI School, Substance abuse evaluation and any recommended treatment |
And remember, in going over the minimum penalties, we are assuming a best-case scenario. You can receive jail time even on a first-time DUI, depending on the circumstances. If you wish to avoid these penalties, speak with a Tampa DUI lawyer about your options.
Florida drivers can face even stricter requirements and penalties in certain situations. For example, Florida has a zero-tolerance policy for drivers under the age of 21. In addition to prosecution under section 316.193, Florida Statutes, drivers under 21 can face penalties and license suspensions if their BAC is just 0.02 or higher. § 322.2616, Fla. Stat. (2023). Further, commercial drivers can face harsh administrative penalties for DUI if their BAC is just 0.04 or higher. § 322.61, Fla. Stat. (2023). Tampa DUI lawyer William B. Wynne brings a wealth of experience in dealing with numerous cases involving these specialized DUI situations.

While most DUI cases involve alcohol, you can also be charged with Driving Under the Influence for being under the influence of drugs, which can even include your own prescription medications. Remember, Florida law defines DUI as being under the influence of alcohol or a chemical substance while operating a motor vehicle. In theory, any narcotic or drug that could potentially impair one’s ability to operate a vehicle safely, could be the basis for a DUI charge. Common drugs that lead to DUI charges include opiates, benzodiazepines like Xanax and Valium, ADHD stimulant medications like Adderall, cocaine, heroin, and even marijuana.
DUI drug charges are often complex and can be more difficult to prosecute than alcohol related DUI charges, but the penalties are essentially the same. The complexity stems partly from the fact that intoxication via drugs does not register on a blood alcohol test. Instead, it is typically determined circumstantially through field sobriety exercises, and the presence of the drug in urine or blood tests. The presence of chemical substances detected in the human body requires complex scientific inquiry, and often leads to evidentiary obstacles for a prosecutor. An experienced Tampa DUI Attorney can recognize and exploit these weaknesses.
Clients frequently ask whether it’s possible to have DUI charges dropped or reduced, or if the case can be dismissed entirely. The answers to these questions depend on the specific circumstances of each case, requiring a detailed analysis of multiple factors. However, an experienced Tampa DUI lawyer can explore a range of defenses to address the charges effectively.
Getting a prosecutor to drop or reduce charges often involves negotiation. Leveraging our extensive experience and knowledge of Tampa DUI cases, we thoroughly investigate all aspects of each case. Our objective is to convince the prosecutor to drop or reduce the charges by highlighting weaknesses in their case. Various mitigating factors, such as the defendant’s background, community involvement, prior military service, and volunteer work, can be instrumental in these negotiations. As Tampa DUI attorneys, we are skilled at utilizing these factors to facilitate negotiations for reduced charges, such as reckless driving.
Achieving a dismissal of the charges typically involves legal strategies within the court system, such as pre-trial motions to suppress evidence or statements, motions to dismiss, or motions in limine to exclude evidence. A motion to suppress evidence challenges the legality of how evidence was obtained and requests the judge to exclude such evidence if it violates the defendant’s rights. Another approach is a motion to dismiss, which argues that even if all the State’s allegations are true, the evidence is insufficient to convict the defendant. As experienced DUI attorneys in Tampa, we frequently pursue these strategies, often filing motions to suppress evidence, as well as seeking the dismissal of charges.

Any criminal case can have numerous defenses. A skilled Tampa DUI defense attorney will exploit all available defenses and leverage them into an overall strategy.
Below are some frequently asked questions and answers pertaining to Driving Under the Influence charges in Florida.
In Florida, a person commits a DUI if they operate a motor vehicle while under the influence of alcoholic beverages, chemical substances, or controlled substances to the extent that their normal faculties are impaired. Under the law, a driver with a blood alcohol concentration (BAC) of 0.08% or higher is presumed to be impaired.
First-time DUI offenders face penalties including fines ranging from $500 to $2,000, up to 9 months in jail (depending on BAC levels or presence of a minor), license revocation between 180 days and one year, vehicle impoundment for 10 days, mandatory 50 hours of community service, and DUI school attendance.
Florida treats DUIs involving drugs similarly to alcohol related DUIs. This can include prescription medications if they impair your ability to drive. DUI charges can result from the influence of any drug that impairs driving ability, such as opiates, benzodiazepines, or stimulants.
Yes, there are several defenses against DUI charges in Florida, including challenging the legality of the traffic stop, the accuracy of the breathalyzer test, or proving that the driver was not in actual physical control of the vehicle. A skilled Tampa DUI Lawyer can utilize these defenses to potentially dismiss or reduce charges.
Florida has a zero-tolerance policy for drivers under 21, where penalties can apply for a BAC of 0.02% or higher. Commercial drivers can face DUI charges for a BAC of 0.04% or higher.
A DUI conviction in Florida can have long-lasting effects, including a permanent criminal record, increased insurance rates, loss of professional licenses, and difficulties in finding employment.
Given the complexities and potential consequences of a DUI charge, securing experienced legal representation is crucial. A qualified Tampa DUI lawyer can significantly influence the outcome by negotiating charge reductions, challenging evidence, and providing a strong defense.
DUI convictions in Florida generally cannot be sealed or expunged, regardless of whether adjudication is withheld. However, if the charges were dismissed, expungement may be an option. Furthermore, if the original DUI charges were reduced to a lesser offense that is not explicitly ineligible for sealing—for example, from DUI to reckless driving—and adjudication is withheld, then sealing the record may become a viable option.
