A two-year-old boy from Taber, Alta., died Wednesday after the all-terrain vehicle he was riding on crashed into a rock.

Taber RCMP said the crash occurred Wednesday evening when five people were riding on the vehicle meant to carry two people.

A 32-year-old man was driving the ATV with four boys as passengers — two 12-year-olds, a two-year-old and a three-year-old — none of whom were wearing helmets, police said.

The vehicle was sitting on top of a steep hillside when one of the children hit the accelerator, sending the ATV forward and down a steep incline. The adult driver was unable to stop the ATV before it hit a rock, which sent the ATV into the air, unseating all the passengers.

The passengers were taken to the Taber hospital where the two-year-old died. The other passengers sustained minor injuries and were released from hospital after treatment.

Police said the name of the child will not be released out of respect to the family.

Police are considering charges in connection with the accident, Sgt. Patrick Webb said.

"We're looking at the possibility of charges," he told CBC News on Thursday.

"But in this case, it is private land that it is being operated on, so whether or not the regulations of helmets apply is a consideration, and whether or not the activities and the actions of the driver, and also the situation with so many people on the quad, certainly, those are all factors we're looking at."
