## Abstract

FMCSA issues regulatory guidance to clarify that a co-driver may make entries to an automatic on-board recording device (AOBRD) while a commercial motor vehicle (CMV) is in motion. The prohibition in 49 CFR 395.15 against making entries to an AOBRD while the vehicle is in motion pertains only to the current driver. This guidance responds to recent inquiries from manufacturers of recording devices concerning updates to the duty status of co-drivers making the transition from the passenger seat to the sleeper berth or vice versa.
