Children (and some sweet-toothed adults) enjoyed the sticky incident, and tucked in to the chocolate which covered three lanes of a motorway.
No-one was hurt, but there was a seven mile traffic jam on the Pinheiros highway in Sao Paulo, as some children actually rolled around in the stuff in their pants!
Best accident ever!
"It was the best accident ever. Everyone was so happy to see all that chocolate" said a police spokesman.
Everyone had to wait for the road to be cleaned up before the cars could carry on their journeys.
But it seems the spill wasn't the biggest problem. The police said: "It was difficult to get the kids out of the road."
