Inspectors from the California Air Resources Board and the California Highway Patrol conducted a heavy-duty truck inspection Tuesday along Jensen Avenue between highways 41 and 99.
The inspections, which measure the smoke coming out of a truck's exhaust pipes and check for proper engine labeling, are part of efforts to enforce state air-pollution laws governing emissions from trucks. Of 66 trucks inspected at two locations Tuesday, CARB spokeswoman Karen Caesar said, 10 drivers were cited. Penalties can start at $300 and range to $1,800 for repeat citations.
Inspectors will be at two different sites in the Fresno area on Wednesday.
Heavy-duty trucks represent 2% of vehicles on California's roads, the ARB reports, but they are responsible for 30% of smog-forming nitrogen oxides and 65% of soot from vehicles.
