A 12-year-old girl has died after being pinned by an ATV in a rural area near Cadomin, Alta., west of Edmonton.

Hinton RCMP say they responded to a crash at a gravel pit about 20 kilometres east of Cadomin on Saturday.

Police say the ATV had flipped over and pinned the young driver.

The girl was wearing a helmet but died at the scene.

Police are reminding ATV operators about the importance of proper training and parental guidance and supervision in the case of when children or young teenagers operate ATVs.

Police say according to the "Off-Highway Vehicle Regulation," children under 14 years old should not drive an off-highway vehicle on public property unless they are supervised by someone 18 years or older. The supervision must be on the vehicle with the young person or in a vehicle travelling close to the young person.

RCMP continue to investigate but charges are not expected to be laid.

There have been at least four other ATV-related crashes in the province, two of those crashes fatal, in recent weeks, prompting safety warnings from police.

Most recently, two ATV riders were sent to hospital Saturday after an ATV crash near Morinville.
