But the evening's festivities took a deadly turn when one of the trucks appeared to lose control climbing over two cars, before plunging erratically into the crowd.
Carlos Gonzalez, a representative for the state attorney general's office, told the Los Angeles Times that the truck's driver was detained on negligent homicide charges.
“So far, the inspection indicates there was a mechanical failure, but we are investigating everything,” he said.
According to BBC News, the driver also tested positive for alcohol.
