Two people died and one person was injured in three separate ATV crashes over the weekend. 

In at least two of the incidents, the ATV driver wasn't wearing a helmet. This has officials reminding people to put on proper safety equipment when riding. 

On Sunday, 30-year-old Justin Bateman of Little Falls was riding northbound on Haven Road in Belle Prairie Township when he hit a driveway approach and was thrown from the vehicle, the Morrison County Sheriff's Office says. 

He was pronounced dead at the scene, with officials noting he wasn't wearing a helmet.

The second fatal crash happened in Meeker County Friday. Officials say David Ahlgren, 66, of Darwin, was spraying weeds on his property and became pinned underneath his ATV, killing him.

A preliminary investigation shows the wheel of the ATV dropped in a wash out, causing the vehicle to roll into a ditch and pin him. 

The third crash happened Saturday, with officials saying alcohol is believed to have been a factor.

The St. Louis County Sheriff's Office says a 21-year-old was riding his ATV up a steep hill when it rolled over. 

He suffered serious injuries, and officials say he wasn't wearing a helmet.
