OBD II

Truth be known, you cannot drive anything, truck, car, motorcycle, in just about any city or town in the US without being filmed. This is a shot of traffic cameras in the Phoenix AZ area.

Here's a screen shot from the TX Department of Transportation traffic cameras.

SO..as anyone can see, they don't need cameras IN the trucks, they already know where you are all the time.

Paper or E logs, doesn't matter, they know where you are.
