Overnight snow and freezing temperatures made overpasses and other areas slick for drivers on the morning commute.
The Highway Patrol said troopers worked 19 accidents on various highways including I-29, I-229 and U.S. Highway 36.
The St. Joseph Police Department responded to 14 accidents.
"It started off pretty normal and then when the traffic flow increased and the roadways were not in great condition this morning, we started getting a series of accidents," said Sgt. Richard Ketchem with the St. Joseph Police Department.
There were only minor injuries from today's accidents.
MoDOT monitored road temperatures throughout the weekend in preparation for possible snow.
Dropping temperatures on Sunday night cooled road temperatures enough to cause freezing in areas.
"Guys are already prepared and ready to go," said Marty Liles with MoDOT.
Crews put down a salt mixture starting at 6 a.m.
Roads were clear later in the day after temperatures rose above freezing.
