Iowa State Patrol Trooper Doug Cutts issues a reminder to everyone on area roadways to watch for farm and heavy equipment as planting season begins. Officer Cutts tells KNIA KRLS News that it is illegal to pass these vehicles in a no passing zone. He says if you have a no passing zone, just slow down, take your time and wait for a passing zone, and he adds that those vehicles have as much right to be on the roadways as everyone else.
