Introduction
This Kentucky Supreme Court decision arises from a fatal hydroplaning crash on a widened segment of Interstate 65 (I-65) near Hart County.
The plaintiffs—Kristina L. Ives (individually, as next friend for her minor children, and as personal representative of Hiram “Dudley” Ives III’s estate)
and the seriously injured driver Jennings L. Copley II—sued engineering firms involved in designing the I-65 widening project.
The defendants (collectively, the “Engineers”) included WSP USA, Inc. (lead design consultant), HMB Professional Engineers (drainage/slope design), and HDR Engineering (more limited role).
The plaintiffs alleged the design increased water flowing across travel lanes—particularly because drainage inlets were omitted in a curved section—creating hazardous pooling and hydroplaning risk.
The Fayette Circuit Court granted summary judgment to the Engineers on two principal grounds:
(1) immunity (in multiple senses, including derivative sovereign immunity concepts and a “mandated design” contractor defense);
and (2) federal preemption based on FHWA governance of National Highway System (NHS) design standards.
The Court of Appeals reversed. The Kentucky Supreme Court granted discretionary review and affirmed the Court of Appeals.
The opinion addresses three intertwined issues:
- Whether private engineering contractors share the Commonwealth’s immunity merely by contracting with KYTC;
- Whether summary judgment was proper on a “government-mandated design” theory (as framed by Kentucky cases such as Rigsby v. Brighton Engineering Co.); and
- Whether Kentucky negligence and wrongful-death claims are impliedly preempted by federal highway design law and FHWA/AASHTO standards.
Analysis
1) Precedents Cited
a) Summary judgment and standard of review
The Court framed its review under Motorists Mut. Ins. Co. v. First Specialty Ins. Corp. (de novo review; summary judgment proper only where no genuine issue of material fact exists)
and Caniff v. CSX Transp., Inc. (de novo standard).
This framing mattered because the Engineers’ defenses depended on whether key “mandated design” facts were undisputed.
b) Sovereign immunity vs. contractor liability
The Court reaffirmed sovereign immunity for the Commonwealth (Comair, Inc. v. Lexington-Fayette Urb. Cnty. Airport Corp.) and acknowledged statutory protection for the state in highway design decisions (KRS 12.211).
But it drew a sharp line between the state’s immunity and a private contractor’s liability.
The controlling historical thread begins with Taylor v. Westerfield, which “plainly overruled” earlier notions that independent contractors could not be liable to third parties for negligence in state work,
holding instead that a contractor is responsible for damages “just as he would be on private work.”
The Court then reinforced that thread through Combs v. Codell Construction Co. (immunity of the government does not absolve contractor negligence)
and Codell Construction Co. v. Steele (rejecting “state-agent” framing to avoid negligence instructions).
The opinion also relied on the modern governmental-immunity analysis in Comair, Inc. v. Lexington-Fayette Urb. Cnty. Airport Corp. (immunity inquiry depends on the entity’s origin and the nature of the function),
and the Sixth Circuit’s application in Shadrick v. Hopkins County, Ky., which denied immunity to a private medical contractor despite performing a governmental function.
The Court used Shadrick v. Hopkins County, Ky. to emphasize that merely contracting with a government entity—even for core governmental services—does not confer immunity where the contractor is a separate private, for-profit enterprise.
The Court also referenced the contractor-liability cases H.H. Miller Constr. Co. v. Collins and Hunt-Forbes Constr. Co. v. Robinson to illustrate the basic negligence baseline:
even where work follows plans, liability still turns on whether the contractor performed without negligence and within the contract’s terms.
The Court distinguished older city-liability cases (Teager v. City of Flemingsburg, Clay City v. Abner, McCourt v. City of Covington) as largely involving allegations against municipalities,
not private engineering consultants seeking to share sovereign immunity.
It likewise distinguished Portwood v. Hoskins-Squier as suit against government and employees, not independent contractors.
It noted Sietsema v. Adams (and the later “reversed on other grounds” note to Adams v. Sietsema) in addressing related immunity reasoning but did not treat it as controlling.
c) The “mandated design” contractor defense line: Rigsby and Padgett
The Engineers relied heavily on Rigsby v. Brighton Engineering Co. and City of Louisville v. Padgett.
In Rigsby v. Brighton Engineering Co., engineers were not liable for failing to recommend guardrails where criteria did not require them and the engineers had “no discretion” to deviate; a recommendation would have been futile.
In City of Louisville v. Padgett, the Court stated that ordinarily a contractor who performs in conformity with highway department plans/specifications is not liable absent negligent or willful tortious acts.
The majority treated these decisions as recognizing an exemption from liability in certain settings, but crucially as a negligence analysis rather than a free-standing grant of “immunity,”
and only where the relevant design feature is genuinely shown to be government-mandated and non-discretionary.
The Court also discussed the unpublished Court of Appeals decision McCarty v. Willett as persuasive background for the distinction between “immunity” and negligence principles when government approval is involved,
noting that factual disputes can preclude summary judgment even when a government body approved a design.
d) Preemption precedents
For preemption doctrine, the Court relied on:
- Niehoff v. Surgidev Corp. (express vs. implied preemption; conflict and field preemption);
- Cipollone v. Liggett Group, Inc. (express preemption as a category);
- N.Y. State Conf. of Blue Cross & Blue Shield Plans v. Travelers Ins. Co. (presumption against preemption);
- Russell v. Johnson & Johnson, Inc. (state tort claims survive when “parallel” and in “harmony” with federal requirements; preemption only to the extent state law imposes a higher duty); and
- CSX Transportation, Inc. v. Easterwood (preemption occurs only when federal rules “substantially subsume” the subject matter; federal standards can be “standards” without displacing state negligence law).
These cases provided the analytical pathway for holding that FHWA/AASHTO standards do not impliedly preempt Kentucky negligence claims that seek to enforce ordinary care consistent with those standards.
2) Legal Reasoning
a) No derivative sovereign/official immunity by contract alone
The Court began with a categorical clarification: sovereign immunity (and related derivative forms) protects the Commonwealth, but does not automatically travel to private contractors.
The opinion grounded this in Kentucky’s longstanding rejection—beginning with Taylor v. Westerfield—of a rule that would shield contractors performing state work from negligence liability.
The Court reinforced this by applying the Comair, Inc. v. Lexington-Fayette Urb. Cnty. Airport Corp. framework through the lens of Shadrick v. Hopkins County, Ky.:
even if a contractor performs a governmental function, it still must derive its existence/status from the government (or be a true governmental agency/agent) to share immunity.
The Engineers were private, for-profit firms, hired through contract, and thus could not claim the Commonwealth’s immunity on that basis alone.
b) “Mandated design” is not “immunity,” and it depends on disputed facts here
The Court separated two ideas that are often conflated in highway-design litigation:
- Immunity (a jurisdictional/status-based protection against being sued at all), and
- A negligence-based contractor defense (no liability when a contractor had no discretion and followed mandatory government criteria/specifications).
While acknowledging that Rigsby v. Brighton Engineering Co. and City of Louisville v. Padgett reflect a Kentucky form of the government-contractor defense,
the majority held summary judgment was improper because the record contained competing proof on whether the challenged design choices were truly mandated or instead reflected engineering discretion within flexible guidance.
Several factual/legal features drove that conclusion:
-
Engineers were retained for expertise and judgment: KYTC’s project manager testified he relied on hired engineers for drainage design.
The KYTC Highway Design Guidance Manual emphasized “flexibility” and that it “should not supersede the application of sound engineering principles by experienced design professionals.”
-
Federal standards were framed as guidance requiring professional application: The AASHTO “Green Book” itself stated it is not a detailed manual supplanting professional judgment and “sufficient flexibility” exists to tailor designs.
-
Design exception record did not resolve the alleged drainage defect: The Engineers obtained a design exception for vertical alignment (stopping sight distance),
but the Court viewed that exception as not tantamount to FHWA approval of the drainage/shoulder-slope feature alleged to have caused pooling.
-
Competing expert proof created genuine issues: Plaintiffs’ expert opined the design failed to meet minimum standards because it caused runoff to traverse travel lanes rather than draining at least part of the shoulder away from traffic;
the Engineers’ witnesses asserted compliance and suggested superelevation/straight-line slope was “standard.”
This conflict is classic jury territory at the summary judgment stage.
The Court highlighted that—unlike Rigsby v. Brighton Engineering Co., where the plaintiffs failed to contradict the showing that the state forbade the desired feature—here the plaintiffs produced competing proof that the safer feature was allowable within the standards.
c) No implied federal preemption: Kentucky negligence claims are “in harmony” with FHWA/AASHTO
The Court found no express preemption in the relevant federal statutes/regulations and rejected implied preemption.
It applied the presumption against preemption from N.Y. State Conf. of Blue Cross & Blue Shield Plans v. Travelers Ins. Co..
Drawing from Russell v. Johnson & Johnson, Inc., the Court reasoned that preemption would arise only if Kentucky tort law imposed a higher or different duty than federal requirements.
Here, the plaintiffs’ theory was not “Kentucky requires more than FHWA,” but that the Engineers failed to meet applicable standards and ordinary care in applying them.
The Court’s reliance on CSX Transportation, Inc. v. Easterwood underscored a key point:
federal “standards” and federal oversight do not necessarily “substantially subsume” the field so as to displace state negligence law, especially where the standards themselves anticipate professional judgment and contextual tailoring.
In short, the Court treated state tort law as complementary to—rather than conflicting with—the federal safety regulatory scheme governing the NHS.
d) The dissent’s competing theory
Justice Nickell’s dissent would have affirmed summary judgment under a robust “governmental contractor defense,” viewing Kentucky law (especially City of Louisville v. Padgett and Rigsby v. Brighton Engineering Co.)
as preventing juries from second-guessing an approved, compliant highway design.
The dissent framed the defense as rooted in “principles of derivative sovereign immunity” and analogized to federal policy concerns about collateral attacks on agency discretion, citing
Hunt-Forbes Constr. Co. v. Robinson and United States v. S.A. Empresa de Viacao Aerea Rio Grandense (Varig Airlines).
The majority, however, viewed the record as presenting genuine disputes over (i) whether the relevant design feature was mandated, and (ii) whether the design met the minimum standards in the first place—making a “compliant and approved” premise unsuitable for summary judgment.
3) Impact
a) Litigation exposure for design professionals on public projects
The decision reinforces that Kentucky will not treat private design professionals as quasi-state actors for immunity purposes simply because they work on state infrastructure.
Engineering firms on KYTC (and analogous) projects should anticipate:
- Being subject to ordinary negligence litigation and discovery even when plans were agency-approved;
- Heavier emphasis on professional-liability coverage, risk allocation, and indemnity provisions (already present in this record); and
- More frequent “battle of the experts” fact disputes that survive summary judgment.
b) Narrowing (or at least fact-intensifying) the “mandated design” defense
The Court did not abolish the Kentucky defense reflected in Rigsby v. Brighton Engineering Co. and City of Louisville v. Padgett,
but it clarified that defendants must show more than “approval” or “standards exist.”
They must show that the specific challenged feature was non-discretionary and actually mandated—and that the contractor complied.
Where design manuals emphasize flexibility and professional judgment, and where expert proof plausibly shows the safer alternative was permitted (and the chosen design may not meet minimum standards), summary judgment is unlikely.
c) Preemption defenses in Kentucky highway design cases
The ruling signals that Kentucky courts will be skeptical of implied-preemption arguments that would categorically displace state tort claims in NHS design cases.
Absent a clear conflict (i.e., state law requiring “more than” or “different than” federal law), negligence claims alleging failure to exercise ordinary care within federal/state standards should proceed.
d) Practical downstream effects
Agencies and consultants may respond by:
- Documenting which elements are truly mandated versus discretionary design choices;
- Explicitly memorializing drainage/hydrology decisions and risk analyses, especially in curved/superelevated sections; and
- More carefully tying any “design exception” approvals to the precise feature later claimed to be defective (to avoid the majority’s “exception mismatch” critique).
