This is a camera we're talking about & due to the fact the camera is pointed in the general direction of the sleeper, where one has a "reasonable expectation of privacy", it would be grounds for a huge lawsuit if you weren't informed about it before getting in the truck.)
They will tell you about it during orientation and by completing orientation and getting in their truck, you're giving consent.
It's probably DriveCam. Another reason to avoid Roehl.
