- The Supreme Court’s decision emphasized the use of common sense and practical reasoning in determining reasonable suspicion under the Fourth Amendment, reversing the Kansas Supreme Court’s stricter standard.
- This ruling has significant implications for both law enforcement practices and individual privacy rights, affecting how courts nationwide interpret reasonable suspicion in traffic stops.
Introduction
Kansas v. Glover is a landmark United States Supreme Court case that addressed a fundamental question under the Fourth Amendment: When does a police officer have "reasonable suspicion" to justify a traffic stop? Decided on April 6, 2020, this case arose from a routine license plate check by a Kansas deputy sheriff. After discovering that the registered owner of a pickup truck, Charles Glover, had a revoked driver’s license, the officer stopped the vehicle without any additional information about who was driving. The Supreme Court’s decision, authored by Justice Clarence Thomas, held that such a stop is reasonable under the Fourth Amendment unless the officer has evidence suggesting the owner is not the driver.
This guide will provide a comprehensive analysis of Kansas v. Glover, including its factual background, procedural history, the Supreme Court’s reasoning, key legal principles, and the broader implications for law enforcement and civil liberties.
Factual Background
The Traffic Stop
On April 28, 2016, Douglas County Sheriff’s Deputy Mark Mehrer was on routine patrol when he ran the license plate of a 1995 Chevrolet 1500 pickup truck. The registration returned to Charles Glover, whose driver’s license had been revoked. Deputy Mehrer did not observe any other traffic violations or suspicious behavior, nor did he have any information suggesting that someone other than Glover was driving the truck.
Relying solely on the registration information and the status of Glover’s license, Deputy Mehrer initiated a stop. Glover was indeed behind the wheel and was charged with driving as a habitual violator.
Procedural History
Glover moved to suppress the evidence obtained during the stop, arguing that the officer lacked reasonable suspicion to believe he was driving unlawfully. The trial court agreed and suppressed the evidence. The Kansas Court of Appeals reversed, finding the stop reasonable under the Fourth Amendment. However, the Kansas Supreme Court reversed again, holding that the officer’s inference amounted to a mere "hunch" and did not rise to the level of reasonable suspicion required by the Constitution.
The State of Kansas appealed to the United States Supreme Court, which granted certiorari to resolve the question.
The Legal Question
The central issue before the Supreme Court was:
Does a police officer violate the Fourth Amendment by initiating a traffic stop after running a vehicle’s license plate and learning that the registered owner’s driver’s license is revoked, when the officer lacks information suggesting the owner is not the driver?
This question required the Court to interpret the meaning of "reasonable suspicion" under the Fourth Amendment and to clarify the standards for investigative traffic stops.
The Supreme Court’s Decision
Majority Opinion
Justice Clarence Thomas authored the majority opinion, which was joined by seven other Justices. The Court held:
“When the officer lacks information negating an inference that the owner is the driver of the vehicle, the stop is reasonable.”
The decision reversed the Kansas Supreme Court’s ruling, finding that Deputy Mehrer’s inference was a reasonable application of common sense and did not violate the Fourth Amendment.
Key Reasoning
- Common Sense Inference: The Court emphasized that, in the absence of evidence to the contrary, it is reasonable for an officer to assume that the registered owner of a vehicle is likely its driver.
- Totality of the Circumstances: The Fourth Amendment’s reasonable suspicion standard is a "less demanding" standard than probable cause and depends on the totality of the circumstances, not certainties or hard evidence.
- Practical Considerations: The Court noted that officers are not required to rule out the possibility of innocent conduct before initiating a stop. Instead, they must have a "particularized and objective basis" for suspecting legal wrongdoing.

Dissenting Opinion
Justice Sonia Sotomayor was the sole dissenter. She argued that the majority’s approach permitted stops based on assumptions rather than individualized suspicion, potentially eroding Fourth Amendment protections. She warned that the decision could result in more frequent and intrusive stops, especially for individuals whose licenses have been revoked or suspended.
Analysis of the Court’s Reasoning
The Fourth Amendment and Reasonable Suspicion
The Fourth Amendment protects individuals against "unreasonable searches and seizures." Under Terry v. Ohio, 392 U.S. 1 (1968), an officer may conduct a brief investigative stop when there is reasonable suspicion of criminal activity. The Court in Glover reaffirmed that reasonable suspicion is based on "commonsense judgments and inferences about human behavior."
The Presumption: Owner as Driver
The Supreme Court recognized a "commonsense inference" that the registered owner of a vehicle is likely the person driving it. The Court found that, statistically and practically, this is often true, and officers may rely on this inference unless there is evidence to the contrary (for example, if the registered owner is a different gender than the observed driver).
Limits and Safeguards
The decision does not grant unlimited authority for stops based solely on vehicle registration. Officers must still consider any information that would negate the inference that the owner is driving. For instance, if an officer observes that the driver does not match the owner’s description (e.g., age, gender, or race), the inference would be unreasonable.
Reversal of Kansas Supreme Court
The Kansas Supreme Court had required more than the mere inference that the owner was driving, characterizing the officer’s suspicion as a "hunch." The U.S. Supreme Court, however, found this standard too restrictive and inconsistent with the Fourth Amendment’s practical approach to reasonable suspicion.

Implications for Law Enforcement
Practical Guidance for Officers
The Glover decision provides clear guidance: absent evidence to the contrary, an officer may initiate a stop based on the assumption that the registered owner is driving. This practical approach streamlines law enforcement’s ability to address traffic violations and other criminal activity associated with revoked or suspended licenses.
Training and Policy Considerations
Law enforcement agencies may update training materials and policies to reflect the Glover decision. Officers should be instructed to consider any available information that might negate the owner-as-driver inference. Agencies may also need to document the basis for stops more thoroughly to withstand judicial scrutiny.
Criticisms and Concerns
Some legal scholars and civil liberties advocates have raised concerns that the ruling could lead to increased traffic stops based on assumptions rather than individualized suspicion. There is a risk that innocent drivers—such as family members or friends using a registered owner’s vehicle—could be stopped without specific evidence of wrongdoing.
The Harvard Law Review provides an in-depth discussion of these issues.
Implications for Individual Rights
Balancing Privacy and Public Safety
Kansas v. Glover underscores the ongoing tension between individual privacy rights and the needs of law enforcement. The decision affirms that reasonable suspicion can be based on probability and common sense, rather than direct evidence. This approach arguably tips the balance in favor of effective policing, but at the potential cost of increased intrusions on individual privacy.
Potential for Abuse
Critics worry that the decision could be used to justify stops based on minimal information, leading to racial profiling or other forms of discriminatory enforcement. Because officers are permitted to rely on general inferences, there is a risk that the standard for reasonable suspicion could be diluted over time.
Judicial Oversight
Courts will continue to play a crucial role in evaluating the reasonableness of traffic stops. The Supreme Court’s decision makes clear that officers cannot ignore evidence that contradicts the owner-as-driver inference. Defense attorneys may challenge stops where officers had access to information suggesting the owner was not the driver.
Broader Legal and Policy Impact
Influence on Future Cases
Kansas v. Glover sets a nationwide precedent for how courts interpret reasonable suspicion in traffic stops. Lower courts across the country are now bound by the Supreme Court’s reasoning, which may lead to more uniform application of the law.
Law Enforcement Technology
The decision interacts with advances in law enforcement technology, such as automatic license plate readers (ALPRs). These systems can rapidly check large numbers of license plates against databases of revoked or suspended licenses, potentially leading to more frequent stops under the Glover standard.
Legislative Responses
Some states may consider legislative reforms to clarify or limit when officers may rely on registration information to initiate stops. Lawmakers could, for example, require additional corroborating evidence before a stop is considered reasonable.
Scholarly and Public Commentary
Support for the Decision
Proponents argue that the Glover decision reflects practical realities and provides law enforcement with a workable framework. By allowing officers to act on reasonable inferences, the ruling supports proactive policing and road safety.
Criticism and Dissent
Critics, including Justice Sotomayor in her dissent, argue that the decision erodes Fourth Amendment protections by allowing stops based on assumptions. Civil liberties organizations have expressed concern that the ruling could disproportionately impact certain communities and increase the number of pretextual stops.

Practical Takeaways for Practitioners
For Defense Attorneys
Attorneys representing clients in traffic stop cases should carefully examine the facts to determine whether the officer had any information that would negate the owner-as-driver inference. If such evidence exists, it may provide grounds for a motion to suppress.
For Prosecutors
Prosecutors should be prepared to articulate the basis for an officer’s reasonable suspicion, emphasizing the lack of contrary evidence and the use of common sense inferences.
For Judges
Judges must evaluate whether, under the totality of the circumstances, the officer’s inference was reasonable. This includes considering any evidence that undermines the owner-as-driver presumption.
