The Missouri Department of Transportation has kicked off its new campaign to stop distracted drivers.

The Buckle-up, Phone Down Challenge day will begin on Tuesday.

MODOT will be working with area high schools to educate drivers and will be posting Buckle Up/Phone Down on message boards. They will also be running a social media campaign encouraging people to post a selfie doing the thumbs up thumbs down sign.

MODOT reports that distracted driving is the leading cause of crashes in the United States.
