The incident began Wednesday afternoon when the semi-trailer's brakes overheated as it travelled down a steep section of Highway 3 near Osoyoos.
The driver veered onto a runaway lane at the base of Anarchist Mountain but the truck overturned and burst into flames.
Osoyoos RCMP Sgt. Kevin Shur says he was right behind the semi-trailer and was relieved to see the driver climb out of the flipped cab, but could only watch as flames from the burning truck quickly spread up the hill.
Area firefighters and drops from air tankers helped contain the blaze to about seven hectares.
No nearby homes were threatened. (CKOR)
