The CHP said the driver of the truck lost control of the vehicle on the transition road from state Route 2 to the eastbound 134 Freeway in Glendale around 3:30 a.m. Wednesday, and the truck crashed through a guardrail and rolled down an embankment, KCBS-TV, Los Angeles, reported Wednesday.
The crash spilled 52,000 gallons of milk, much of which was seeping into storm drains, authorities said.
The driver was hospitalized with minor injuries.
CHP Officer Jennifer Cassidy said firefighters are "considering it a haz-mat spill" and taking health precautions, the Los Angeles Times reported.
