The accident caused the deaths of two people and two others sustained serious injuries in what police say was an alcohol related accident along the Magi Highway in the Central Province.

"It's about time the Police Traffic introduce random BAC testing along our Highways and within city roads. It should be a zero tolerance approach. Drivers caught over this alcohol limits should be taken off the road and charged," one said.
