Over 100 truck drivers showed up at the Port of Oakland on Monday, not to move cargo but to protest a state labor law they say could end their independence — and their livelihood.

The truck drivers — independent owner-operators who work for themselves — temporarily held up other trucks trying to enter the port to pick up or drop off cargo and backed up traffic at the sprawling shipping complex. They vowed to continue protesting through Wednesday amid chants of “free our drivers.”
