Background
On the morning of March 23, 2022, fifteen-year-old A.D. was struck and injured by a car while crossing a road near Dekaney High School in Harris County, Texas. The accident occurred in darkness, before Harris County’s school-zone flashing beacons — which signal drivers to reduce speed — were programmed to activate at 6:50 a.m. The driver was traveling between thirty and forty miles per hour. A witness reported A.D. appeared to be looking at her phone while crossing; A.D. herself acknowledged she saw the car and believed she had time to cross.
A.D. and her guardian sued Harris County under the Texas Tort Claims Act (TTCA), arguing the County negligently maintained the school-zone flashers by programming them to activate too late. A.D. relied on Texas Administrative Code regulations advising that school speed zones generally should be in effect from “approximately 45 minutes before school opens until classes begin,” and contended the County was required to activate the flashers before student drop-off began at 6:50 a.m. Harris County countered that the flashers were functioning exactly as programmed and that timing decisions were discretionary acts protected by governmental immunity.
The County filed a combined plea to the jurisdiction and motion for traditional and no-evidence summary judgment. The trial court denied both without explanation, and the County appealed.
The Court’s Holding
The First Court of Appeals reversed and rendered judgment dismissing A.D.’s claims against the County for lack of subject-matter jurisdiction. The court held that the school-zone flashers had no “condition” or “malfunction” within the meaning of TTCA Section 101.060(a)(2) because the flashers functioned exactly as programmed and conveyed precisely the intended traffic-control information — alerting drivers to slow down beginning at 6:50 a.m. Following the Texas Supreme Court’s analysis in TxDOT v. Garza, the court reasoned that A.D.’s real complaint was about how the County set the flashers’ activation time, not about any defect in the devices themselves, and that a policy decision of that kind does not trigger the TTCA’s waiver of immunity.
The court further held that the timing of school-zone flasher activation is a discretionary decision shielded by immunity under TTCA Section 101.056. Analyzing the Texas Administrative Code, the court found that the use of “generally,” “should,” and “approximately” throughout the relevant regulation — terms the Code itself defines as advisory rather than mandatory — conferred flexibility on the County rather than imposing a fixed legal obligation. The court read the regulation as establishing maximum intervals of operation, not minimum activation requirements, meaning the County had lawful discretion to activate the flashers at 6:50 a.m.
Finally, the court rejected A.D.’s negligent-implementation theory, distinguishing the El Paso Court of Appeals’ decision in City of Midland v. Sullivan. In Sullivan, the city had an existing policy of activating flashers thirty minutes before classes and failed to update signs when the school district added earlier “zero hour” classes — a failure of implementation. Here, there was no allegation or evidence that the County deviated from its own policy; A.D.’s challenge was directed at the County’s programming decision in the first instance, which is a policy matter immune from suit.
Key Takeaways
- A school-zone flasher that operates exactly as programmed and conveys its intended message has no actionable “condition” or “malfunction” under TTCA Section 101.060(a)(2), even if the activation time is allegedly unreasonable — the alleged defect lies in the programming decision, not the device.
- Texas Administrative Code Section 25.22’s use of “generally,” “should,” and “approximately” renders school-zone flasher activation intervals advisory, not mandatory, preserving governmental discretion and immunity under TTCA Section 101.056.
- The negligent-implementation exception to discretionary-function immunity requires a showing that the governmental unit deviated from its own existing policy — a challenge to the underlying policy itself does not qualify.
- Plaintiffs bear the burden of establishing a waiver of governmental immunity to invoke a Texas trial court’s subject-matter jurisdiction; absent evidence of a device defect or a mandatory legal duty, that burden cannot be met.
Why It Matters
This decision reinforces a narrow reading of the TTCA’s waiver of governmental immunity in traffic-device cases. By drawing a clear line between a malfunctioning or misprogrammed device and a deliberate (if arguably imprudent) policy choice, the court insulates Texas counties from tort liability arising out of school-zone design and scheduling decisions — even where injuries to children occur in predictable danger windows. Attorneys representing injured plaintiffs in similar cases must now focus on establishing either a mechanical defect in the device or a clear mandatory legal duty that the governmental unit violated, rather than arguing that a policy was simply unwise.
The opinion also offers a practical primer on how Texas courts will parse regulatory language when governmental immunity is at stake. The explicit Code definition of “should” as advisory — and the court’s reliance on ordinary dictionary meanings of “generally” and “approximately” — signals that ambiguous safety regulations will typically be construed in favor of governmental discretion. Local governments should nonetheless take note: had the County maintained a written policy requiring earlier activation and simply failed to follow it (as in Sullivan), the outcome may well have been different.
