The Iowa State Patrol says a Missouri truck driver was cited following an accident Tuesday afternoon on Interstate 29, in Mills County. Officials say a semi driven by 54-year old Daniel Smoot, of Atlanta, MO, was traveling south near mile marker 35 on I-29 at around 4:20-p.m.

After Smoot and the driver of a semi who was near him exchanged words over the C.B. radio, Smoot merged in front of the other semi, driven by 61-year old Stephen Greever, of Red Oak, and slammed on the brakes. Greever’s semi hit the back of Smoot’s truck, causing Greever’s vehicle to become disabled. Both drivers suffered minor injuries, but refused transport to the hospital.

Smoot was cited for Failure to Signal a Stop or Rapid Deceleration. Damage to his 2012 Volvosemi, registered to Dickey Transport, was estimated at $10,000. Greever’s 2004 semi, registered to Sully Transport, sustained $4,000 damage.
