A 12-year-old boy from southeast Saskatchewan has been killed in an all-terrain vehicle accident.

Colton Lee Golling died Thursday.

The accident happened near the small community of Grayson, about 60 kilometres south of Melville.

According to the RCMP, a preliminary investigation shows the boy had been driving on a grid road, lost control of the ATV and tumbled down an embankment into a slough. He was killed when the ATV rolled on top of him.

The boy, who had been wearing a helmet,had been alone at the time. He was later found by his parents.

RCMP Staff Sgt. Brent Lewis said such accidents are preventable.

"Just common sense … wear a helmet when you're driving them," he said. "Drive them safely and appropriately."

Also, a driver's licence is required for anyone using a vehicle on a public roadway, he said.

According to Lewis, police in the area are embarking on a public information campaign to promote safe ATV riding.
