The California Air Resources Board (CARB) that regulates air quality in California is holding a public hearing on Oct. 23 2003, to consider requiring that all heavy-duty truck engines built between 1993 and 1998 include computer software to reduce nitrogen oxides emissions, even if the trucks are not registered in the state. CARB estimated the rule would affect 100,000 in-state heavy-duty trucks, school buses, and motor homes and approximately 300,000 to 400,000 more vehicles that travel in California.
