A semi-truck overturned near Whitewater on Friday afternoon spilling 60 gallons of diesel and oil onto the ground.
CHP arrived on scene just before 2 p.m. near the eastbound 10 freeway west of Haugen Lehmann Way.
For unknown reasons the semi-truck pulled over to the right-hand shoulder of the freeway, apparently got to close to the edge and rolled over onto Railroad Way.
The driver required extrication and sustained minor injuries, according to Cal Fire.
Hazmat crews were called to the scene.
Railroad Way will be closed for several hours.
