FMCSA ordered JBS Carriers Inc., of Greeley, Colo., to install Electric On Board Recorders (EOBR’s) after the agency’s western service center found the company “in serious violation of federal HOS rules and commercial driver’s license requirements,” FMCSA said in a statement. The ruling applies to all 700 trucks in the JBS fleet.

The order announced November 4, 2010, is believed to be the first of its kind. If JBS fails to comply, it is subject to $81,780 in fines.
