NASCAR fans at the Daytona 500 witnessed a new kind of roar this year — courtesy of the world’s loudest billboard.

The massive digital display, installed near the race track, combined high-decibel audio with vibrant visual effects to energize spectators before the start of the iconic race. The installation was officially recognized by Guinness World Records for setting a new benchmark in sound output for an outdoor advertising structure.

The billboard’s sound system, designed to be heard clearly over the roar of racing engines, played pre-race music, announcements, and team introductions, creating an immersive experience for fans both in the stands and around the venue. Engineers carefully calibrated the decibel levels to ensure safety while delivering a record-setting impact.

Fans reacted with excitement, describing the combination of visuals, audio, and racing atmosphere as “thrilling” and “unforgettable.” NASCAR officials said the initiative highlighted the organization’s commitment to innovative fan engagement, blending technology, entertainment, and record-breaking spectacle.
