Police forces across Quebec are warning the public about the “Lug Nut Challenge,” a dangerous social media trend that involves unscrewing the wheel nuts on motor vehicles.
Police Reports and Regional Incidents
Between June 5 and July 28, four separate reports were logged by the Régie de police de Memphrémagog (RPM) in the Eastern Townships, according to a police press release. Incidents occurred in the parking lot of a business and within residential neighborhoods located in Magog, Orford, and Sainte-Catherine-de-Hatley. The RPM intervened in another similar case in October 2025, bringing the total to five cases, of which three could have ended in serious tragedies. An ongoing police investigation aims to identify the individuals responsible for removing the nuts.
Additional cases of untightened nuts were confirmed via email by the Service de police de l’agglomération de Longueuil (SPAL). According to SPAL spokesperson Jacqueline Pierre, one case might have been linked to a garage tire change, but the hypothesis of a deliberate act remains plausible for others. Longueuil currently has three open files for mischief involving vehicles, although the spokesperson notes that the municipality faces no major issues tied directly to the challenge. Meanwhile, the Service de police de la Ville de Montréal (SPVM) is aware of the trend circulating online, but no cases have been reported in Montreal.
Mechanical Dangers and Criminal Consequences
Jean-Philippe Delorme, a trucker and former garage employee, explained in a telephone interview how loosening wheel nuts affects a vehicle. The wheel detaches from the hub—the central component positioned between the rim and the axle—creating an axis shift that accelerates the separation until the nuts fall off and the wheel comes entirely loose. A TikTok video shows a driver losing a wheel directly on the highway following such tampering.
Because of these severe risks, police emphasize that the trend reaches far beyond a harmless online prank. According to Kim Cormier, information officer for the Sûreté du Québec (SQ), determining that an incident is an intentional act or a prank can lead directly to charges of mischief or criminal negligence. While the SQ does not track the exact number of cases tied to the phenomenon across the province, the agency published a warning video last autumn to explain the mechanics of wheel tampering and urged motorists to check their vehicle’s mechanical state before driving.
Did You Know? The Sûreté du Québec launched an informational video campaign last autumn to educate the public on the mechanics of wheel tampering after observing the ongoing circulation of the trend across the province.
Platform Response and Prevention
TikTok has faced mounting criticism and accusations of inaction regarding the Lug Nut Challenge. In response to public pressure, the platform implemented an awareness message that appears whenever users search for videos related to the challenge. The notification warns users that certain online challenges can be dangerous or fabricated, and provides a four-step evaluation process to help audiences assess online trends safely. The RPM similarly advises parents to talk openly with their adolescents about the trend, while the SQ emphasizes that users must exercise sound judgment and discernment when navigating social media ecosystems.
