Truck Regulations Upload and Compliance Reporting System (TRUCRS)


The California Air Resources Board (CARB)requires fleet owners to register and report their diesel-powered vehicles, those affected by the Truck and Bus Regulation.

Fleet owners must report through the Truck and Bus regulation reporting system online. Fleets are encouraged to report early, before the January 31st reporting deadlines.

2017 Reporting

The reporting period for 2017 compliance is not yet open. CARB will typically announce the open and closing reporting dates in December.

2016 Reporting

The reporting period for 2016 is now closed. Those who had opted-in to mileage based extensions must have reported end of year odometer readings and confirm whether continuing to use the same option or not. By reporting, owners take advantage of certain flexibility options.

The following is a list of the compliance options and reporting deadlines:
NOx exempt area operation January 31 of any year
Low-use January 31 of any year
Low-Mileage Work Truck Option January 31 of any year

Note: must report odometer reading and confirm selection before deadline.
