ATRI Identifies Problems With FMCSA Hours-of-Service Field Study Report
On Tueday, the American Transportation Research Institute (ATRI) released the findings of its independent evaluation of the Federal Motor Carrier Safety Administration’s (FMCSA’s) field study report on the new Hours-of-Service (HOS) rules. FMCSA was directed by Congress as part of MAP-21 to study the efficacy of the restart provisions which went into effect July 1, 2013.
FMCSA’s field study collected fatigue measurements from 106 truck drivers during two duty cycles that included two restart breaks. FMCSA stated that their field study results supported the efficacy of the new restart rule. Following a detailed evaluation of the field study report, ATRI identified a variety of technical issues related to research design flaws, validity of measurement techniques and interpretations and data conflicts within and across the study.
