Two teenagers landed in hot water after they were charged with posting hardcore pornography on a highway billboard in Michigan.

An anonymous tip helped investigators identify the suspects, who also were caught on surveillance video entering a shed to access a laptop used for posting the X-rated footage.

Motorists were distracted by the X-rated footage for about 15 to 20 minutes before it was taken down on September 28, The Auburn Hills Police Department said.

Motorists were distracted by the X-rated footage for about 15 to 20 minutes before it was taken down on September 28, The Auburn Hills Police Department said. A glimpse of the shocking footage was caught in this image taken by a passing motorist

Sex scenes showed up on the screen just before 11pm, causing a stir with motorists for several minutes as they drove past, some taking photos and videos which they posted on social media.

The pornographic video footage played over Interstate 75, or I-75, near Detroit, until cops were able to contact the owner to shut off the video feed.

The younger of the two boys, who cops said was responsible for getting into the shed, was entered into a juvenile diversion program, reports WJBK.

If he completes the program successfully, it will result in a dismissal of charges.

The other teen was charged with trespassing and was not jailed.

Cops said they were first alerted about the porn videos played on the billboard after receiving reports from drivers.

The billboard is located on the east side of I-75, south of highway M-59, and displays a digital image facing both north and south.

'Officers arrived on scene and witnessed the video being displayed at that time. We were able to contact an emergency contact for the private business, which operates the sign, and they were able to shut down the sign,' police said in a report about the incident posted on Facebook.

'We believe that the video may have been playing for at least 15 to 20 minutes before it was turned off.'

Police said the owner of the sign was Triple Communications, which is part Triple Investment Group, also owner of the former Pontiac Silverdome, a domed stadium that was used by the Detroit Lions professional football franchise and the NBA's Detroit Pistons. It was condemned and demolished in 2018.

Representatives with Triple Communications were said to have cooperated with police. The did not immediately respond when Dailymail.com reached out.

Before knowing the arrests, the police had warned of the severity of posting pornography on the billboard.

'Promoting pornography and/or promoting pornography for minors by disseminating any pornographic material, images, videos, etc. is a violation of an Auburn Hills local ordinance with a possible penalty of 90 days in jail and/or a $500 fine,' the cops wrote on Facebook.

'These suspects now face potential burglary charges for forcing entry into the building to gain access to the computer system, which is a felony offense.'

Hacking road signs is reportedly a fad, reports Patch.

A sign in Whitley County, Kentucky, was found briefly flashing the words, 'send nudes,' on Thursday, Patch reports.

State transportation officials had to explain to the public that they weren't soliciting naked images.
