Highlighting the importance of state agencies in regulating the trucking industry, the State of California removed the license to carry hazard materials, including gasoline, of the company involved in the collapse of a section of highway last month.

On a day that Gov. Arnold Schwarzenegger touted the 25-day repair of a collapsed MacArthur Maze ramp as the “best side” of government Friday, the trucking company involved in the fiery April 29 gasoline tanker wreck that weakened the ramp lost its license to carry gasoline.

The California Highway Patrol slapped Sabek Trucking of South San Francisco with an indefinite suspension of its hazardous materials transportation license, in effect killing its only business of hauling gasoline to about 20 Bay Area convenience stores.

It was the first time the state suspended any trucking company since 1992, when the law empowering the highway patrol commissioner to do so was enacted.
