PERSONAL INJURY | AUTO ACCIDENTS | GOVERNMENT LIABILITY | SOVEREIGN IMMUNITY | FLORIDA LAW UPDATE | FEBRUARY 2026
A new Third District Court of Appeal decision clarifies when injured drivers can hold municipalities liable for road design implementation failures, even when the original design decisions are protected by sovereign immunity.
Published: February 11, 2026
Case: City of Hialeah Gardens v. Anathalia Castellanos, et al.
Court: Florida Third District Court of Appeal
Decision Date: February 11, 2026
The Applicable Law
Florida’s sovereign immunity doctrine protects government entities from most lawsuits, but it contains an important exception. Under Florida law, cities and counties are immune from liability for “planning-level” decisions that involve basic policy choices, but they can be held liable for “operational-level” failures that occur when implementing those policies.
The Florida Supreme Court established this distinction in Commercial Carrier Corp. v. Indian River County, explaining that “planning level functions are generally interpreted to be those requiring basic policy decisions, while operational level functions are those that implement policy.” This means that while a city cannot be sued for deciding where to build a road or what safety features to include in the design, it can potentially be held liable if it fails to properly install or maintain those safety features as designed.
Key Legal Rule: Cities are protected by sovereign immunity for planning and design decisions, but not for operational failures to implement approved designs.
What Happened in This Case
According to the facts described in the court’s opinion, the plaintiffs were injured in a head-on collision on a street within the City of Hialeah Gardens. The record reflected that another driver crossed into the opposing lane of traffic, causing the crash that injured the plaintiffs.
The allegations in the case centered on the city’s handling of road safety features. The plaintiffs filed multiple versions of their complaint, with the city successfully getting the first two dismissed based on sovereign immunity. However, in their Second Amended Complaint, the plaintiffs changed their legal strategy significantly.
The evidence described in the court’s opinion was that “the City of Hialeah Gardens failed to install or implement roadway signage such as, but not limited to, solid double line lane road strips indicating a no passing zone, or roadway signs warning drivers not to pass into the opposing lane, all of which had been previously designed to be installed or implemented by government authority officials.” The plaintiffs specifically alleged this represented “an operational failure to install or implement such roadway signage.”
The trial court noted an important distinction: “The complaint no longer merely relies on the failure to design or on a critique of the design. Instead, it relies on the City’s alleged failure to install what was designed.”
The Court’s Analysis
The Planning vs. Operational Distinction
The appellate court applied the established legal framework from Department of Transportation v. Neilson, which held that “discretionary, judgmental, planning-level decisions were immune from suit, but that operational-level decisions were not so immune.”
The court explained that planning-level functions typically include decisions about whether to build roads, where to locate them, and what safety features to include in the original design. As the court noted, “the failure to install traffic control devices and the failure to upgrade an existing road or intersection, as well as the decision to build a road or roads with a particular alignment, are judgmental, planning-level functions and absolute immunity attaches.”
Critical Distinction: The difference between protected planning decisions and unprotected operational failures often comes down to whether the government entity made a policy choice or failed to implement an already-made decision.
Why This Case Was Different
The court found that the plaintiffs’ negligence claim was “not based on the City’s decision to build the road or its design of the road, which constitutes a planning-level function.” Instead, the allegations focused on the city’s “failure to construct the road as designed, which is an operational-level decision.”
This distinction proved crucial. The court emphasized that the plaintiffs were not challenging the city’s planning or design choices, but rather alleging that the city failed to follow through on implementing safety features that had already been designed and approved.
Supporting Precedent: The Perez Case
The court relied heavily on Miami-Dade County v. Perez, 343 So. 3d 175 (Fla. 3d DCA 2022), which involved similar operational-level claims. In that case, the court explained that “while the county’s decision to install a ‘stop ahead’ sign and the proper location for that sign constitute planning-level decisions which would be immune from suit, operational-level actions implementing those decisions would not be.”
The Perez decision established that even when the initial planning decisions are protected by immunity, the actual implementation of those plans can create liability if done negligently.
Frequently Asked Questions
Can I sue my city if I’m injured in a car accident on a poorly designed road?
Generally, cities are protected by sovereign immunity for their planning and design decisions about roads. However, if the city failed to properly install or maintain safety features that were already designed and approved, you may have a valid claim. The key is whether you’re challenging the design itself (usually protected) or the implementation of that design (potentially liable).
What’s the difference between a planning decision and an operational decision?
Planning decisions involve basic policy choices, like where to build a road, what speed limit to set, or whether to include certain safety features in the design. Operational decisions involve implementing those policies, such as actually installing approved signage, maintaining road markings, or replacing worn safety equipment. Cities can typically be sued for operational failures but not planning decisions.
How do I prove a city failed to implement an approved design?
You’ll need evidence showing that safety features were designed or planned but never properly installed, or that they were installed but not maintained as required. This might include engineering plans, city records, inspection reports, or expert testimony about what should have been in place versus what actually existed at the time of your accident.
Does this ruling mean all road accident victims can now sue cities?
No. This ruling only applies when there’s evidence that a city failed to implement approved safety measures. If your accident was caused by factors unrelated to missing or improperly maintained safety features, or if the city’s design decisions themselves were the issue, sovereign immunity may still apply.
What should I do if I think a city’s road maintenance failure contributed to my accident?
Document the accident scene thoroughly, including photos of road conditions, missing or faded signage, and any safety features that appear inadequate. Gather police reports and witness statements. Most importantly, consult with an experienced personal injury attorney who can investigate whether the city had approved plans for safety features that weren’t properly implemented.
Taking Action After a Road-Related Accident
Cases involving government liability for road conditions are among the most complex in personal injury law. They require extensive investigation into government planning documents, engineering standards, and maintenance records. The distinction between protected planning decisions and actionable operational failures can be difficult to navigate without experienced legal guidance.
