Police continue to remind the public that off-road vehicles are not suitable for children to drive.

The warning comes after an ORV flipped with six children aboard Monday morning. Two of the children were sent to hospital.

Police were called to a home west of Clinton on Maitland Line around 10:30 a.m.

They say a 12-year-old girl from Rothesay, N.B. was operating the vehicle when she lost control.

A 9-year-old girl from Rothesay was air-lifted to a London hospital with non-life threatening injuries. A 13-year-old girl from Central Elgin had minor injuries.

The other children involved, all boys, were between the ages of three and 10 and were sitting on the cargo bed of the vehicle. The driver and the boys were not injured. None of the children were wearing helmets or safety gear.

Police say the adults on the property were not aware the vehicle was being used.

OPP Sgt. Dave Rektor says only experienced drivers should handle the vehicles.

"Our message is this, you need to be trained and qualified to drive an off-road vehicle, regardless of what type of off-road vehicle it is."

Hully Gully of London sells about 200 of these machines each year.

Staff say education is key because the machines are powerful.

"You can go anywhere from 100 to 120 kilometres an hour," says Hully Gully's Chuck Collins. "They're all basically fuel injection so there is no hesitation. You hit that throttle and there is instant power."

Earlier this month, a 9-year-old boy was in critical condition after five children on an ATV crashed into two trees.
