According to the California Highway Patrol, the big rig was traveling westbound on the 210 and continuing on the curve to the westbound 210 in Pasadena when the driver lost control and hit a center median at about 1:15 a.m.
The big rig went through a guard rail, which then became tangled under the big rig. No other vehicles were involved, CHP said. Crews had to clean up a small amount of diesel that spilled onto the roadway.
The accident also impacted traffic on the eastbound 134 Freeway to the westbound 210 transition road. All lanes reopened just after 5:30 a.m.
CHP says the big rig was likely going too fast for the slick roads and warned other drivers to slow down.
