Was the traffic stop legal? What Venice, FL drivers need to know.
If you’ve been arrested for DUI in Venice, Florida, one of the most important questions to ask is: “Was the traffic stop legal?”
Under both Florida law and the United States Constitution, police officers must have a lawful reason to stop a vehicle. If the stop was made without reasonable suspicion or probable cause, the entire DUI case may be subject to challenge — and potentially dismissed.
At Casella Law Group, we examine every DUI arrest with a critical eye — beginning with the traffic stop itself. Whether you were pulled over along Tamiami Trail, Venice Avenue, or during a holiday DUI checkpoint in Sarasota County, the legality of the stop is the foundation of any valid prosecution.

Understanding the Legal Standard: Reasonable Suspicion vs. Probable Cause
To make a lawful stop in Florida, a police officer must have reasonable suspicion that a crime or traffic infraction has occurred. This standard is lower than probable cause, which is required for an arrest but not for an initial stop.
Common Justifications for a DUI Stop:
Speeding or reckless driving
Swerving, lane drifting, or crossing center lines
Running a red light or stop sign
Equipment violations (e.g., broken taillight)
Erratic braking or failing to signal
A report from another driver or a BOLO (“be on the lookout”)
A DUI checkpoint stop
Importantly, if the officer did not have a legal reason to initiate the stop, all evidence gathered afterward — including field sobriety tests, breath tests, or statements — may be inadmissible in court.
When Is a Stop Invalid?
A DUI stop may be invalid under the Fourth Amendment if:
The officer stopped the vehicle without reasonable suspicion
The officer acted on a hunch or anonymous tip without corroboration
The stop was pretextual and involved unlawful profiling
The driver was stopped at a checkpoint that failed to follow constitutional guidelines
In any DUI defense case, attacking the validity of the stop is one of the first areas a defense lawyer investigates. If the stop was unlawful, everything that followed — including your arrest — may be thrown out.
Factors DUI Attorneys Consider When Evaluating the Validity of the Stop
1. Dashcam and Bodycam Footage
Many police vehicles and body-worn cameras in Sarasota County capture audio and video of the traffic stop. This footage can:
Confirm or contradict the officer’s report
Show whether the driver was driving erratically or obeying traffic laws
Help evaluate the tone, approach, and conduct of the officer
Attorneys often file discovery requests to obtain this footage immediately.
2. Officer’s Narrative in the Police Report
The arrest affidavit and narrative usually include the officer’s reasoning for the stop. A defense attorney will review this report carefully to:
Identify inconsistencies
Check for vague or boilerplate language (e.g., “driver appeared nervous” or “smelled of alcohol”)
Challenge the basis for reasonable suspicion
If the report lacks specific details or contradicts physical evidence, it could support a motion to suppress.
3. Independent Witnesses or Surveillance Footage
In some cases, a passenger, nearby driver, or business surveillance camera may provide a different version of events than the officer’s. For example:
A witness may confirm the driver was not swerving
A video may show the stop occurring without any apparent traffic violation
Such evidence can significantly undermine the prosecution’s case.
4. Was the Officer Acting on an Anonymous Tip?
Florida courts have held that an anonymous tip (e.g., a phone call to 911 about a drunk driver) does not provide reasonable suspicion unless the officer corroborates the claim with independent observation.
Example: If someone calls in saying a car is “driving all over the road,” but the officer follows the car and sees no erratic behavior, then initiates a stop anyway — that may be legally invalid.
5. Checkpoint Legality
If your DUI arrest stemmed from a checkpoint (common in Sarasota County during holidays), your attorney will examine:
Whether the checkpoint was announced publicly
Whether the police followed a neutral, predetermined plan (e.g., stopping every 3rd vehicle)
Whether signage and lighting complied with legal standards
If officers deviated from these requirements, the stop — and everything that followed — could be suppressed.
The Exclusionary Rule: What Happens if the Stop Was Illegal?
If a court finds that the traffic stop was invalid, the defense attorney can file a Motion to Suppress under Florida Rule of Criminal Procedure 3.190(h). If granted, this motion would exclude all evidence obtained as a result of the illegal stop.
This could include:
Field sobriety test results
Breath or blood alcohol tests
Statements made by the driver
Observations about the driver’s appearance, speech, or odor
In many cases, suppressing this evidence results in the entire DUI case being dismissed, since the State lacks the evidence needed to prove guilt beyond a reasonable doubt.
Case Example: DUI Stop Thrown Out in Sarasota County
In a recent Sarasota County case, a driver was pulled over near U.S. 41 and Venice Avenue for allegedly “driving too slowly.” The officer claimed the driver’s speed was suspicious but did not observe any swerving, braking, or traffic violations.
Upon challenging the stop, the defense presented dashcam footage showing the driver was traveling at 35 mph in a 45 mph zone — well within legal limits.
The judge ruled that the stop lacked reasonable suspicion, and the breath test result (0.11 BAC) was excluded. The case was dismissed.
This case demonstrates how even a high BAC result can be suppressed if the stop was unlawful.
Pretextual Stops: Legal But Still Questionable
In Whren v. United States (1996), the U.S. Supreme Court ruled that an officer’s subjective intent doesn’t invalidate a stop, as long as there is an objective traffic violation.
However, in practice, Florida courts still scrutinize pretextual stops involving:
Racial profiling
Out-of-jurisdiction enforcement
Lack of actual violation
An experienced DUI attorney may still use the circumstances of the stop to challenge credibility, bias, or misconduct — especially if combined with other procedural issues.
