Just before midnight on Saturday, emergency lines in Auburn Hills, Michigan started ringing. Drivers were calling from the interstate to report an electronic billboard was suddenly playing porn.

According to the Detroit Free Press, the billboard is located alongside I-75 North between University Drive and highway M-59 in Auburn Hills. According to Redditors, porn aficionados, and Motherboard's own extensive research, the video belongs to adult performers Xev Bellringer and Princess Leia.

Multiple people called 911 to report the drive-by bigscreen blowjob. Several local news reports said that to get the giant sex scene to stop, the authorities contacted the billboard's owners. Detroit ABC news affiliate station WXYZ confirmed that the billboard belongs to Triple Communications.

"I've never seen or heard of anything like this," Gagnon told Detroit Free Press, adding that the video was a serious distraction to drivers and could have caused an accident.

Detroit-area dentist Justin Kammo told WXYZ that when he passed the billboard, several other drivers were braking on the interstate and rubbernecking to see the video.
