There is no e-log mandate. The one which was for the "bad actors" was thrown out in court. The FMCSA cannot mandate EOBR's until they can ensure the devices cannot be used to harass drivers. The judge has already stated that, which is why the "bad actors" rule was tossed. OOIDA had 2 other arguments against the EOBR's which the court didn't even need to look at because their 1st argument was sufficient to have the rule tossed.
In other words, when the FMCSA comes out with another EOBR mandate, it will be back in court. If they have not adequately addressed the driver harassment issue, that rule will again be tossed out. If they have guaranteed that drivers cannot be harassed by the carrier due to the use of an EOBR, then the other arguments will be heard.
Many of the ATA companies are starting to use them. Hell, the ATA is PUSHING for the mandate. My truck, however, will never have one installed. I'll hang up the keys & park the #### thing before I allow the carrier or the DOT to electronically track & record my every move.
