Groups of semi trucks are moving from Highway 99 to Southbound I-5, protesting against new electronic log books truck drivers are supposed to start using next year, according to California Highway Patrol spokesperson Chad Hertzell.

The semi trucks are stopping along the highway in clusters, waving flags and protesting, Hertzell said.

CHP asked truck drivers to remain at the side of the road and not to block traffic. The protests are happening through October 6th, according to CHP.
