Let’s start by exploring the differences between DUI and DWI in Florida and what these terms mean under state law.

What is a DUI in Florida and How Does It Differ from DWI?

A DUI, or Driving Under the Influence, is defined in Florida as operating a vehicle while impaired by alcohol, drugs, or a combination of substances. The state exclusively uses the term “DUI” to describe these offenses, while “DWI” (Driving While Intoxicated) is used in other jurisdictions but has no legal bearing in Florida.

Under Florida law, a DUI occurs when:

  1. Blood Alcohol Concentration (BAC): A driver’s BAC measures 0.08% or higher for adults.
  2. Impairment Indicators: The driver is visibly impaired by alcohol or drugs, regardless of BAC levels.
  3. Controlled Substances: Impairment is due to illegal drugs, prescription medications, or other chemical substances.

Why Doesn’t Florida Use the Term “DWI”? 

Florida exclusively uses the term “DUI” because it consolidates impaired driving offenses involving alcohol or drugs under one definition. According to Florida Statute §316.193, driving under the influence (DUI) covers impairment by alcohol, drugs, or a combination of both, eliminating the need for a separate term like “DWI” (Driving While Intoxicated). In contrast, other states differentiate “DWI” for alcohol-related offenses and “DUI” for drug-related offenses, but Florida’s approach avoids this distinction for simplicity and consistency.

Examples of DUI Scenarios in Florida:

  • A driver failing a field sobriety test after consuming alcohol at a social event.
  • An individual impaired by prescription medications, such as painkillers or sedatives, leading to erratic driving behavior.
  • A recreational marijuana user stopped for weaving between lanes.

Does Florida’s DUI Law Cover Non-Motorized Vehicles?

Yes, Florida extends DUI laws to include bicycles, golf carts, and other non-motorized vehicles. This means individuals can be charged even if they are not operating a traditional motor vehicle.

For individuals facing DUI charges, criminal defense strategies often focus on challenging evidence, procedural errors, or mitigating penalties. With experienced legal guidance, defendants can navigate Florida’s strict DUI laws and protect their rights.

What Are Florida’s BAC Limits and Impairment Thresholds?

Florida’s BAC (Blood Alcohol Concentration) limits are the primary benchmarks used to determine whether a driver is impaired and legally intoxicated. These limits vary based on the type of driver, with stricter thresholds for minors and commercial drivers to promote road safety and accountability.

Florida BAC Limits

  1. Adult Drivers (21 and older): A BAC of 0.08% or higher constitutes legal impairment.
  2. Underage Drivers (under 21): Florida enforces a zero-tolerance policy, setting the BAC limit at 0.02%.
  3. Commercial Drivers: A BAC of 0.04% or higher leads to a DUI charge due to the added responsibility of operating commercial vehicles.

Can You Be Arrested with a BAC Below the Legal Limit?

Yes. Florida law allows DUI charges if a driver exhibits signs of impairment, regardless of their BAC. For instance, a driver testing below 0.08% may still face arrest if they show impaired motor skills or judgment due to alcohol or drug consumption.

How BAC Is Measured in Florida

  • Breath Tests: Commonly used during traffic stops for on-the-spot BAC evaluation.
  • Blood Tests: Performed when breath tests aren’t feasible, such as after an accident.
  • Urine Tests: Typically employed in cases of suspected drug impairment.

Factors That Influence BAC Levels

  1. Body Weight and Composition: Smaller individuals often reach higher BAC levels faster than those with larger body mass.
  2. Alcohol Consumption Rate: The type and amount of alcohol consumed play a significant role.
  3. Metabolism and Food Intake: Drinking on an empty stomach accelerates alcohol absorption, leading to quicker impairment.

Consequences of Exceeding BAC Limits

Drivers who exceed these limits face immediate penalties, including:

  • First Offense: Fines ranging from $500 to $1,000, license suspension for up to six months, and possible jail time.
  • Repeat Offenses: Harsher fines, mandatory installation of ignition interlock devices, and longer suspensions.

What Happens If You Refuse a Breathalyzer in Florida?

Florida’s implied consent law imposes penalties for refusing chemical tests, which emphasizes compliance during DUI investigations. Let’s explore what these refusals mean for drivers.

What Are the Penalties for a DUI Conviction in Florida?

A DUI conviction in Florida carries serious penalties that increase with repeat offenses and aggravating factors. These penalties are designed to deter impaired driving and ensure public safety but can have far-reaching consequences for individuals.

Penalties by Offense Type

  1. First Offense:
    • Fines: $500–$1,000.
    • License Suspension: Up to 6 months.
    • Jail Time: Up to 6 months.
    • Additional Penalties: Probation, mandatory DUI school, and possible installation of an ignition interlock device.
  2. Second Offense:
    • Fines: $1,000–$2,000.
    • License Suspension: Up to 1 year.
    • Jail Time: Up to 9 months (or more if the BAC was 0.15% or higher).
    • Ignition Interlock: Mandatory installation for at least one year.
  3. Third Offense (Within 10 Years):
    • Felony Charge: Third-degree felony.
    • Fines: Up to $5,000.
    • License Suspension: Up to 10 years.
    • Jail Time: Up to 5 years.
  4. Fourth or Subsequent Offenses:
    • Felony Charge: Third-degree felony.
    • Fines: Up to $5,000.
    • Permanent license revocation.

Aggravating Factors That Increase Penalties

  • High BAC Levels: A BAC of 0.15% or higher leads to enhanced fines and longer jail terms.
  • Causing an Accident: If the DUI results in injury or property damage, additional charges and restitution apply.
  • Driving with a Minor in the Vehicle: This doubles certain penalties, reflecting the increased danger to passengers.

How Penalties Impact Your Life

Beyond the immediate consequences, DUI convictions can:

  • Lead to job loss due to a criminal record or suspended license.
  • Increase insurance premiums significantly for years.
  • Result in long-term financial strain from fines, fees, and legal costs.

For individuals facing these charges, criminal defense lawyers play an important role in reducing penalties and exploring alternative sentencing options. MSO Law is dedicated to helping clients minimize the impact of DUI convictions on their personal and professional lives.

Florida’s DUI laws also apply to drug impairment, covering both legal and illegal substances. Drivers can face DUI charges if their ability to operate a vehicle is impaired by prescription medications, over-the-counter drugs, marijuana, or controlled substances.

What Drugs Can Lead to a DUI Charge?

  1. Prescription Medications: Painkillers, sedatives, and other medications with warning labels about drowsiness or impaired motor skills.
  2. Over-the-Counter Drugs: Antihistamines or sleep aids that can cause drowsiness or delayed reactions.
  3. Illegal Substances: Marijuana, cocaine, and other controlled substances.
  4. Combination of Substances: Using multiple substances (e.g., alcohol and medication) increases impairment and likelihood of a charge.

How Is Drug Impairment Detected?

Florida law enforcement officers are trained to recognize drug impairment through:

  • Field Sobriety Tests (FSTs): Physical coordination tests to detect impairment.
  • Drug Recognition Experts (DREs): Officers certified to identify drug-impaired driving.
  • Chemical Tests: Blood or urine samples to confirm the presence of drugs.

Penalties for Drug-Impaired DUI

Penalties for drug-impaired driving are equivalent to those for alcohol-related DUI offenses:

  • First Offense: Fines, probation, license suspension, and potential jail time.
  • Repeat Offenses: Enhanced penalties, including mandatory rehabilitation programs.

Defenses for Drug-Related DUI Charges

Challenging a drug-impaired DUI involves examining:

  • The accuracy of field sobriety and chemical tests.
  • Whether the stop and arrest complied with legal procedures.
  • Medical evidence demonstrating no impairment.

What Should You Do If Arrested for DUI in Florida?

Facing a DUI arrest can be a daunting experience, but your immediate actions can protect your rights and improve your chances of a favorable outcome. Following a clear plan ensures you avoid missteps that could complicate your case.

Steps to Take After a DUI Arrest

  1. Remain Calm and Respectful:
    • Cooperate with law enforcement by providing your license, registration, and proof of insurance.
    • Avoid aggressive behavior, which could escalate the situation or result in additional charges like resisting arrest.
  2. Avoid Self-Incrimination:
    • Politely decline to answer questions about drinking or drug use without a lawyer present.
    • Remember, any statement you make can be used against you in court.
  3. Comply with Required Testing:
    • Florida’s implied consent law mandates chemical testing. Refusing a test could lead to automatic license suspension, affecting not just DUI cases but also traffic-related offenses.
  4. Record Details of the Arrest:
    • Take note of the time, location, officer’s behavior, and any tests administered. This information can help your legal team challenge the circumstances of your arrest.
  5. Contact a Qualified DUI Attorney:
    • A DUI charge is serious, but with proper legal representation, you can explore defenses or alternative sentencing options.
