Bad Driving – Understanding DUI Investigation Evidence Standards

Bad Driving Alone is Not Enough for DUI Investigation

In a recent bad driving Florida case, State of Florida v. Nicole Lynn Diaz, the court ruled that the officer did not have sufficient evidence to detain the defendant for a DUI investigation. This ruling underscores the importance of reasonable suspicion and probable cause in DUI stops.

Key Case Details

• Case: State of Florida v. Nicole Lynn Diaz
• Court: Circuit Court, 9th Judicial Circuit, Orange County
• Judge: Martha C. Adams
• Date: December 11, 2024

Officer’s Bad Driving Observations and Actions

Officer Nickolas Lawrence of the Maitland Police Department testified that:

• He observed the defendant’s vehicle making serpentine movements and rapid acceleration/deceleration.
• The driver, Nicole Diaz, had slow speech and mirrored, glassy eyes.
• There was no odor of alcohol detected.
• Diaz denied consuming alcohol.
• The officer did not inquire about medical conditions or impairment due to illness.

Court’s Decision and Legal Reasoning

• The court found insufficient reasonable suspicion for detaining Diaz for a DUI investigation.
• The absence of affected drivers and lack of concrete deviation details weakened the prosecution’s case.
• Bodycam footage did not confirm slow speech.
• The court granted Diaz’s Motion to Suppress evidence obtained after the unlawful detention.

Factors Considered in DUI Traffic Stops

Legal Precedents Supporting the Decision

The defense cited multiple cases to support their argument:

• Crooks v. State, 710 So.2d 1041 (Fla. 2d DCA 1998): No impact on other drivers weakens reasonable suspicion. Here is a summary of that case: “Section 316.089 provides in pertinent part:
  Whenever any roadway has been divided into two or more clearly marked lanes for  traffic, the following rules, in addition to all others, consistent herewith, shall apply:
  
  (1) A vehicle shall be driven as nearly as practicable entirely within a single lane and shall not be moved from such lane until the driver has first ascertained that such movement can be made with safety.
  
  Because the record does not establish how far into the right-hand emergency lane Mr. Crooks drove on any of the three occasions, there is no basis to state that he was outside the “practicable” lane. Even if he was briefly outside this margin of error, there is no objective evidence suggesting that Mr. Crooks failed to ascertain that his movements could be made with safety. Section 316.089 is similar to section 316.155, Florida Statutes (1995), governing the use of turn signals, in that a violation does not occur in isolation, but requires evidence that the driver’s conduct created a reasonable safety concern. See State v. Riley, 638 So.2d 507 (Fla. 1994). No such evidence exists in this case.
  Accordingly, the motion to suppress should have been granted. We reverse the conviction and order of probation, and direct that the information be dismissed.”
• Jordan v. State, 831 So.2d 1241 (Fla. 5th DCA 2002): Mere lane deviation without additional impairment signs is insufficient. Here is a summary of that case: “In the instant case, we must agree with Jordan that the record is insufficient to establish that his vehicular movements, as testified to by the arresting officer, created any danger to himself or other traffic. Indeed, the testimony of the officer clearly established that other vehicles, including his own, were not in danger by Jordan’s driving. There was no testimony indicating that Jordan was intoxicated or otherwise impaired, nor was any erratic driving pattern established. The applicable statute in this case recognizes that it is not practicable, perhaps not even possible, for a motorist to maintain a single lane at all times and that the crucial concern is safety rather than precision. We believe that the arresting officer’s testimony at the suppression hearing failed to establish probable cause to reasonably believe that Jordan had committed any traffic infraction justifying the stop of his vehicle, even under the objective test of Whren.”
• Hurd v. State, 958 So.2d 600 (Fla. 4th DCA 2007): DUI investigations require clear impairment indicators beyond bad driving. Here is a summary of that case: “Admittedly, the officer did observe appellant speed up and then drive slow, but even to the officer, this did not create a suspicion of impairment or constitute erratic driving.   Under an objective standard, appellant’s driving, while not perfect, was not sufficiently erratic, in light of the caselaw, to give rise to a reasonable suspicion of impairment.   Where a motorist is stopped for an alleged traffic code violation that subsequently proves not to be a violation of any traffic law, or where there was not probable cause of a traffic infraction, the evidence seized following such a stop should be suppressed.   See Riley, 638 So.2d at 508. Accordingly, we reverse appellant’s conviction and sentence and remand with instructions that an order be entered granting his motion to suppress and for further proceedings consistent with this opinion. Reversed and Remanded.”

Common Defenses Against DUI Charges

• Lack of Reasonable Suspicion: Officers must articulate why they suspected impairment.
• Faulty Field Sobriety Tests: Poor test conditions or medical conditions can affect results.
• No Odor of Alcohol: Lack of smell can challenge alcohol-related impairment claims.
• Medical Conditions: Certain conditions mimic DUI symptoms.
• Improper Police Procedure: Failure to follow proper protocol can lead to suppression of evidence.

STATE OF FLORIDA, Plaintiff, v. NICOLE LYNN DIAZ, Defendant. Circuit Court, 9th Judicial Circuit in and for Orange County. Case Nos. 2024-CT-300639-A-E and 2024-CT-300690-A-E. Division 83. December 11, 2024. Martha C. Adams, Judge. Counsel: Matthew P. Ferry, Lindsey, Ferry & Parker, P.A., Maitland, for Defendant.

ORDER GRANTING DEFENDANT’S

MOTION TO SUPPRESS

THIS MATTER having come before the Court on the Defendant’s Motion to Suppress, a hearing was held on November 22, 2024, and the Court having heard argument from Counsel and having reviewed the Court file and being otherwise duly advised, determines the following facts:

On March 27, 2024, Officer Nickolas Lawrence of the Maitland Police Department was behind a black Tesla at the stoplight at the intersection of Horatio and Highway 17-92. As the Tesla made the left turn on to 19-92, Officer Lawrence testified he sees the car make drastic lane changes (going back and forth three separate times, making serpentine movements). He also watched the car rapidly accelerate and then deaccelerate at least two times. Based on this driving pattern, he believed the driver may be ill, impaired or need medical attention.

Officer Lawrence makes a traffic stop and finds a woman behind the wheel in the driver’s seat. When he contacts her, he notices her speech is slow and he can see she has mirrored, glassy eyes. He requests her driver’s license and insurance. She can produce her driver’s license from the wallet in her purse and she is identified as Nicole Diaz. While Officer Lawrence testifies, he is not able to smell any odor of alcoholic beverages and Ms. Diaz denies having had any alcohol to drink, he later requests her to step out of her vehicle for a DUI investigation. Lawrence admits he never asks her if she is sick, injured or in need of any medical assistance.

The defense argues there is no evidence for a valid traffic stop. Defense cites to Crooks v. State, 710 So.2d 1041 (Fla. 2d DCA 1998) [23 Fla. L. Weekly D1323b], Jordan v. State, 831 So.2d 1241 (Fla. 5th DCA 2002) [27 Fla. L. Weekly D2651a], and Hurd v. State, 958 So.2d 600 (Fla. 4th DCA 2007) [32 Fla. L. Weekly D1594a], claiming no other vehicles were affected by the Defendant’s driving pattern and there was no testimony that while there may have been some deviation from lanes of traffic, Officer Lawrence could not recall where these specific events occurred or recall how far she deviated from her lane of travel. Finally, they argue that while Lawrence may have believed Diaz was sick or injured, he never asked her any questions about her health or the if she needed medical assistance.

Furthermore, Defense argues the detention of Diaz to then complete a DUI investigation without further evidence of impairment was illegal. Lawrence was unable to testify to the smell of an odor of alcoholic beverage. Diaz denied she had anything to drink that night. Lawrence also testified Diaz had slow speech which was not evident in the video. This left only an observation of her eyes being mirrored and glassy. Therefore, this court agrees with the Defense that there was not enough reasonable suspicion to order the Defendant out of the car for a DUI investigation. Therefore, it is hereby

ORDERED and ADJUDGED as follows:

The Defendant’s Motion to Suppress is GRANTED.
