Authorities were in pursuit of a stolen U-Haul truck that was pulling a trailer on the 605 Freeway in Whittier Tuesday morning.
Authorities believe the 26-foot U-Haul Super Mover is being driven by a single male occupant. The Super Mover is the largest truck U-Haul offers to the public for moving.
The driver was being followed by California Highway Patrol units as it transitioned to the westbound 60 Freeway in El Monte about 5:15 a.m.
Aerial video from Sky5 showed the trailer sparking behind the truck, which appeared to be traveling at about 60 or 70 mph.
Shortly before 5:30 a.m., the driver transitioned the truck to the northbound 5 Freeway on the East L.A. interchange.
