Heavy Duty Truck and Bus Surveillance Program (TBSP)
This page last reviewed January 25, 2016
This testing program is modeled after ARB’s In-Use Vehicle Surveillance Program (VSP), which has been measuring emissions from privately-owned light-duty vehicles for over 20 years. The primary objective of surveillance programs is to determine a “snapshot” of the emissions from the statewide fleet. The Truck and Bus Surveillance Program specifically will assess the real-world effectiveness of heavy-duty vehicle emission control systems, such as diesel particulate filters and selective catalytic reduction systems. With this type of information, more cost-effective regulations and strategies for reducing heavy-duty truck emissions can be developed.
Automotive Testing & Development Services, Inc. (ATDS), to obtain vehicles for testing from willing truck owners.
Each vehicle will be transported to the Depot Park Facility in Sacramento, California, where it will remain for two to eight weeks. Each vehicle will undergo a series of tests including on-board diagnostic (OBD) checks in the laboratory to better understand the emissions. Vehicles with up to one million miles are being solicited for testing. Pollutants such as carbon monoxide, carbon dioxide, nitrogen oxides, and particulate matter will be measured as part of this test program.

- How do I
participate in this program?
To participate, visit the Automotive Testing & Development Services, Inc. web site. They can also be reached by e-mail at email@example.com or telephone at 1-909-390-1100. The ATDS web site includes additional information regarding program eligibility.
- Will I be
compensated if I allow my vehicle to be tested in this program?
Yes, owners will be provided with financial compensation based on a competitive weekly rate for the duration of the testing.
- How long will
my vehicle be kept for this test program?
In most cases, an owner's vehicle will be returned after 4 to 8 weeks. ARB will maintain close communication with the vehicle owner through ATDS during the rental and testing period.
- Is my vehicle
insured while it is being tested?
Yes, ARB fully insures the vehicle from the time they receive it from the owner's home or work and until they return the vehicle back to the owner.
- What kind of
testing is performed on my vehicle?
The vehicle is placed on a chassis dynamometer, which is like a treadmill for a vehicle, and is operated by a Class A licensed driver to simulate appropriate loads in the laboratory. As the vehicle is driven, the vehicle's exhaust is sampled and weighted against the mileage driven. When the test is completed, exhaust emissions such as hydrocarbons, carbon monoxide and oxides of nitrogen are quantified in mass per distance. The vehicle will be tested as it is and will not be altered or disassembled during the testing.
- How many
miles are added to my vehicle?
The Truck and Bus Surveillance Program will include between 300 and 500 miles of driving on the chassis dynamometer in the laboratory. Additional mileage may be added during transport to and from ARB’s Depot Park Facility located in Sacramento, CA.
- When do I get
my incentive check?
The incentive check will be issued to the owner when the vehicle is returned at the completion of testing period. When ARB returns an owner’s vehicle to ATDS, the vehicle will be washed and be completely refueled, returned to the owner, and an incentive check will be issued.
- What if I
don't want to participate?
The program is completely voluntary – your participation is not required for compliance with any ARB regulations.
