The Ontario Provincial Police pulled over a 19-year-old on Saturday after the young driver was spotted driving at 191 mph (308 km/h) in a Mercedes-Benz C63 AMG Coupe on Queen Elizabeth Way.

In a video shared on Twitter, OPP Sgt. Kerry Schmidt said he was “pretty much speechless” after being informed about the speeding car, saying it is “the fastest speed that I’ve ever heard of. Unbelievable speeds, we’re taking 191 mph (308 km/h).”

CBC reports that the 19-year-old driver was on an area of highway where the speed limit varies between 62 mph (100 km/h) and 68 mph (110 km/h). There was another 19-year-old man riding in the passenger seat. The teenage driver had his license suspended, was charged with street racing, stunt driving, dangerous driving, and the car was impounded for seven days.

According to Schmidt, the 19-year-old borrowed the C63 AMG from his parents. Schmidt added that when he was sent a photo of the radar gun showing 308 km/h, he thought the officer was joking and had actually just been at the nearby airport training his laser on planes taking off.

“This is ridiculous. This is unbelievable. This is irresponsible and I certainly hope this person will not be any position to drive a vehicle for a very long time,” he said.

“You may think you’re in control until that moment you’re out of control,” Schmid added. “At that point there is nothing you can do and you are going to be out of control and you’re going to be done.”

Stunt driving carries fines of up to $10,000 and can result in six months in jail and a loss of license for up to two years.

“I’m sure he’s [the driver’s] got a little bit of explaining to do to mom and dad this Mother’s Day morning, wondering why [their] car is no longer in the garage,” Schmidt added.
