The U.S. National Highway Traffic Safety Administration (NHTSA) has requested public comments on the estimated time and cost burdens of collecting information that “will be used to recruit participants for a field study on vehicle occupant protection technologies and to get information from study participants about their experience with such technologies. The study focuses on occupant protection technologies that restrict some vehicle functionality, permanently or temporarily, when they detect that a vehicle occupant is not wearing a seat belt.”The estimated time burden for responding to the agency’s eligibility, demographic and post-study questionnaires is 46 hours, at a cost of $972. Comments are requested by May 12, 2014. See Federal Register, March 13, 2014.
