The Vai-Vai samba school's parade commenced around 5:40 AM, significantly later than the scheduled time of 4:25 AM, due to safety concerns regarding oil that had been spilled on the track following the previous parade by Acadêmicos do Tatuapé. The oil spilled from one of the allegories, necessitating a halt in the parades while maintenance crews cleaned the runway to ensure the safety of participants and spectators.

As the cleaning took its course, the Rosas de Ouro samba school, which performed before Vai-Vai, also faced delays because of the same issue, highlighting the operational challenges during the high-stakes event. While the situation was resolved and Vai-Vai finally entered the Sambódromo, the dawn provided a dramatic backdrop, with orange hues illuminating the floats, which intriguing aligned with this year's parade theme.

The incident underscores the complexities of managing large-scale events like the São Paulo Carnival, where technical difficulties can disrupt schedules and affect multiple performances. As Brazil's Carnaval is a major cultural and tourist attraction, ensuring safety while maintaining the festivities is a key concern for organizers and participants alike.
