A misdemeanor arrest warrant was issued for San Francisco 49ers wide receiver Brandon Aiyuk following a viral video of him speeding [1].

The legal action highlights the potential for social media posts to serve as direct evidence in criminal traffic investigations. Because the video was shared publicly, it provided authorities with a visual record of the incident that led to the current charges.

The Santa Clara County District Attorney’s Office issued the warrant on a charge of exhibition of speeding [1], [3]. The incident occurred near Levi’s Stadium in Santa Clara County, California [1], [3].

According to court records, the traffic case was originally opened in late January 2026 [2], [4]. However, the warrant itself was reported in June 2026 [3]. The charge is classified as a misdemeanor [1].

Police opened the investigation after Aiyuk posted a video that subsequently went viral [1], [2]. The footage showed the athlete speeding past the stadium, which prompted the legal proceedings in Santa Clara County [1], [3].

Representatives for the San Francisco 49ers have not yet issued a public statement regarding the warrant or the pending misdemeanor charge. Aiyuk has not yet been reported as being in custody.

This case underscores the increasing intersection of athlete branding and legal liability. By posting high-speed driving footage to a public forum, Aiyuk provided the Santa Clara County District Attorney’s Office with a self-documented admission of a crime, bypassing the need for eyewitnesses or traditional police surveillance to establish the 'exhibition of speeding' charge.
