In most cases, commercial motor vehicles (CMV) are no longer required to chock trailer wheels when parking at loading docks. In an agreement between the Federal Motor Carrier Safety Administration (FMCSA) and OSHA, authority over CMV parking issues belongs to the FMCSA. Consequently, OSHA’s wheel chocking requirements in 29 CFR 1910.178(k)(1) and 1910.178(m)(7) of the Powered Industrial Truck standard no longer apply to commercial motor vehicles.
