Skateboarder Decio Lourenco knew he had helped trigger a speed camera as he raced down a steep road from Table Mountain into Cape Town, South Africa, reaching speeds of up to 110km/h.
Footage of his stunt shows the 24-year-old raising his arms in triumph moments after the fixed camera's flashing light goes off in the 60km/h zone.
"Spoofing the Traffic Camera – Longboarding without Limits" was uploaded to YouTube on January 26 and has since garnered more than 220,000 views.
But now Mr Lourenco, a graphic design student, faces prosecution for reckless and negligent road behaviour.
Cape Town's road safety authorities say he could have caused a major crash on the busy road.
The footage, filmed by a friend using a camera strapped to his car bumper, shows Mr Lourenc zipping down Kloof Nek Road at sunset on January 20, passing within metres of oncoming cars.
A GPS sensor fitted to his ankle kept track of his speed.
However, it is not clear whether he or the car filming the stunt set off the speed camera.
Jean-Pierre Smith, Cape Town's safety and security spokesman, said he had put other road users at risk.
"All that was needed was for one of those motorists to panic and swerve into the oncoming traffic and you have a large number of deaths, as we have already had on that road," he was quoted by The Telegraph newspaper as saying.
Mr Smith said he had asked local prosecutors to lay charges.
"If we don't act a whole bunch of other kids who don't have these skills will attempt to do the same and will end up an ornament on the front of a car or a truck," he told ninemsn.
