Section 440.120 Scope
These standards show the basic
federal motor vehicle safety standards that must be met and in addition set
forth certain minimum requirements established by the State to govern aspects
not governed by the federal motor vehicle safety standards. In compliance with
the desires of school bus owners and operators, some of the State requirements
relate to bus traffic characteristics and to durability and maintenance rather
than to safety.
