Authorities believe that truck overturned after a latch between the truck and the trailer became unsecured which caused the two parts to separate. Thousands of gallons of chocolate spilled into the roadway and crews had to empty out the remaining contents from the trailer so it could be lifted upright.

Authorities had to shut down the road for hours. Luckily, no injuries were reported.
