=== Vehicle telematics ===

OBD II information is commonly used by vehicle telematics devices that perform fleet tracking, monitor fuel efficiency, prevent unsafe driving, as well as for remote diagnostics and by [[pay-as-you-drive]] insurance.

Although originally not intended for the above purposes, commonly supported OBD II data such as vehicle speed, RPM, and fuel level allow GPS-based fleet tracking devices to monitor vehicle idling times, speeding, and over-revving. By monitoring OBD II DTCs a company can know immediately if one of its vehicles has an engine problem and by interpreting the code the nature of the problem. It can be used to detect reckless driving in real time based on the sensor data provided through the OBD port.<ref>{{Cite journal|last=Shashika|first=Muramudalige|date=24 August 2015|title=Cloud-based driver monitoring and vehicle diagnostic with OBD2 telematics|url=https://popularapk.com/wp-content/uploads/2022/02/CloudBasedDriverMonitoringOBD2.pdf|journal=IEEE International Conference on Electro/Information Technology|via=Academia.edu}}</ref> This detection is done by adding a complex events processor (CEP) to the backend and on the client's interface. OBD II is also monitored to block mobile phones when driving and to record trip data for insurance purposes.<ref>{{Cite web|title=What is Vehicle Telematics?
