Missouri Buckle Up Phone Down Campaign

Early in 2017, the Missouri Department of Transportation (MoDOT) launched the Buckle Up Phone Down (BUPD) challenge to drive down the increasing number of fatalities on Missouri roadways. The challenge focuses on two critical issues every Missourian can help address: unbuckled fatalities and distracted driving crashes. While only 13 percent of Missourians aren't buckling up, nearly two-thirds of people killed in crashes in the state are unbuckled.
