What it does

FMCSA amends the emergency equipment rules to remove the requirement for commercial motor vehicles (CMVs) to be equipped with at least one spare fuse for each type and size of fuse needed for the operation of the CMV. This change will remove an unnecessary requirement from the Federal Motor Carrier Safety Regulations (FMCSR).
