the Truck Stop

All diesel fueled trucks, buses, trailers and transportation refrigeration units operating in California, including those based out of state, are required by regulations to take steps to reduce air pollution. Please call the California Air Resources Board (ARB) Diesel Hotline at 866-6DIESEL (866-634-3735) for more information, or click the links below. Operators are available to answer questions in Spanish and Punjabi.

Diesel Hotline Alert: Please be aware that the ARB Diesel Hotline is experiencing high call volumes resulting in intermittent periods where you may receive a busy signal. Should your call go to voice mail, it will be answered in the order it was received. Note that the Truck and Bus regulation reporting deadline has been extended from January 31, 2012 to March 30, 2012.
