The 18-wheeler was reported stolen just after 8 p.m. from a yard in the Los Angeles area.
When officers caught up to the vehicle, it refused to pull over. They chased the vehicle on the northbound 5 through the San Fernando Valley and then west on the 118 into Simi Valley.
The truck drove just under the highway speed limit, around 50-60 mph, through much of the freeway chase. A logo for a food service company was painted on the side of the truck.
