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 extremely high call volumes resulting in intermittent periods where you may receive a busy signal. Note that the Truck and Bus regulation reporting deadline has been extended from January 31, 2012 to March 30, 2012. If you are experiencing difficulties getting through to the hotline, please call back another day.
