Short video, basically any truck with an engine newer than 2000 will have to register, and also allow for even their engine to be monitored. The new regulations have caused quite the stir, as the ELD regulations require apparently 24/7 while in the cab monitoring. They know when you drive, when you idle, and just about everything else..

When I say everything else, apparently with this monitoring, they themselves are monitored; as their personal information is uploaded as well.
Many are concerned about their privacy; obviously.
