Quick Answer
Remote Monitoring allows qualifying vehicles to complete required emissions testing during normal vehicle operation using a CARB-approved monitoring device. Once installed and activated, the device communicates with the vehicle's onboard diagnostic system and securely transmits required emissions data when testing requirements are met.
What Is Remote Monitoring?
Section titled “What Is Remote Monitoring?”Remote Monitoring is a CARB-approved compliance option for qualifying vehicles.
Rather than scheduling a manual emissions inspection, an approved monitoring device collects emissions-related information while the vehicle is being driven during normal operation. When the required testing criteria have been met, the emissions information is submitted electronically as part of the Clean Truck Check program.
How the Process Works
Section titled “How the Process Works”The remote monitoring process is designed to be straightforward:
- A compatible monitoring device is assigned to the vehicle.
- The device is installed and activated.
- During normal vehicle operation, the device communicates with the vehicle’s onboard diagnostic system.
- When CARB testing requirements are satisfied, the required emissions information is transmitted electronically.
- Monitoring continues throughout the service period to support ongoing compliance.
Benefits of Remote Monitoring
Section titled “Benefits of Remote Monitoring”For qualifying vehicles, remote monitoring offers several advantages:
- Testing occurs during normal vehicle operation.
- Reduces the need to schedule manual emissions testing.
- Minimizes vehicle downtime.
- Simplifies compliance management.
- Helps fleet managers monitor multiple vehicles more efficiently.
Vehicle Eligibility
Section titled “Vehicle Eligibility”Not every vehicle qualifies for remote monitoring.
Common Misunderstanding
Section titled “Common Misunderstanding”Installing a remote monitoring device does not automatically make a vehicle compliant.
Bottom Line
Section titled “Bottom Line”Remote Monitoring provides a convenient compliance option for qualifying vehicles by allowing required emissions testing to occur during normal vehicle operation. While it simplifies the testing process, vehicle owners remain responsible for meeting all applicable Clean Truck Check requirements.
