A five-year-old boy is in serious condition after an ATV and a truck collided in southwestern Saskatchewan.

The crash happened on a gravel road in the Rural Municipality of Miry Creek around 8 p.m. Tuesday.

RCMP say the boy, who was driving the ATV, was taken by STARS air ambulance to a hospital in Saskatoon.

The man driving the truck wasn’t injured.

Mounties say alcohol was not a factor in the collision, and the child was wearing a helmet at the time.

An investigation is underway, but so far, no charges have been laid.
