The ELD (electronic logging device) reports this data to the trucking company. It is up to them to enforce driving time. However, law enforcement can request these logs during a stop or inspection and the ELD must display this on screen or a print out. https://eld.fmcsa.dot.gov/
Trucker forums are full of ways to cheat the devices like simply pulling a fuse or replacing it with one that's been burned out, and police can't / won't check electronic logbooks because it's too much of a hassle for them.
The companies installing the electronic logbook devices are the same people who have incentive to cheat the system. So do you think anyone notices, complains, or gets disciplined when "the fuse keeps burning"?
