The Federal Motor Carrier Safety Administration has posted a plan for how it will conduct the “naturalistic study” of the operational, safety, health and fatigue impacts of the hours-of-service restart provisions that Congress has mandated it to conduct.
Per the agency, the plan explains how a research team will measure and compare the fatigue and safety performance levels of drivers who take two or more nighttime rest periods during their 34-hour restart break and those drivers who take only one nighttime rest period during their restart break.

The plan details the assessment technologies that will be used, study procedures, and the sampling plan and data analyses involved.

Those restrictions were rolled back in December by Congress and will remain so until FMCSA completes the mandated study of the rule or until September 30 of this year, whichever comes later.
