SUBPART A:  INTRODUCTION  
 
Section 440.10  Order   
 
The Department, through its Division of Traffic Safety, has the responsibility to ensure that the 
public and private agencies engaged in the transportation of passengers on school buses are 
cognizant of and meet minimum safety standards related to vehicle construction.  
 
Section 440.20  Guidelines   
 
This Part provides:  
 
a) General information on the appropriate portions of the Illinois Vehicle Code [625 
ILCS  5], the applicability of the standards to public and private agencies, the 
purpose of the standards and the scope of the standards.  
 
b) Definitions of terms used in this Part.  
 
c) Requirements for manufacturer's certification related to federal and Stat e 
standards.  
 
d) Federal and State standards applicable to the bodies of school buses.  
 
e) Federal and State standards applicable to the chassis of school buses.  
 
Section 440.30  Responsibilities   
 
The Bureau of Safety Programs, Division of Traffic Safety, is responsible for enforcement of 
these standards.  
 
SUBPART B:  GENERAL  
 
Section 440.110  Purpose   
 
These standards are intended to heighten the safety of school bus passengers in compliance with      ILLINOIS REGISTER             10757  
 17 
DEPARTMENT OF TRANSPORTATION  
 
NOTICE OF PROPOSED REPEALER  
 
 the oft -expressed desires of parents and other promoters of school bus safety features.  
 
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 durabili ty and maintenance rather than to safety.  
 
Section 440.130  Applicability   
 
These standards apply to the construction of any new Type I School Bus obtained by a person or 
organization for operation on the public roads in Illinois. Requirements for body and chassis are 
stated separately, in order to facilitate application of the st andards to the commonly used body -
on-chassis bus. In the case of an integral type bus the body and chassis requirements (Subpart E 
& F) should be read together as one set of requirements.  In any case, these standards apply to 
the completed bus.  
 
Section 440.140  Effective Date   
 
These standards become effective July 1, 1977, on each incomplete vehicle manufactured on or 
after April 1, 1977, and on each component either assembled to or altered on such incomplete 
vehicle so as to construct a school bus; pro vided, however, a new school bus constructed of an 
incomplete vehicle manufactured before April 1, 1977, may not be sold or used in Illinois if its 
final stage of manufacture is completed after October 1, 1977.  
 
Section 440.150  Quantified Requirements   
 
Nearly all quantified requirements are stated in SI (metric) units as well as U.S. customary units.  
Where a requirement stated in U.S. customary units is not identical to the requirement stated in 
SI units, the SI requirement shall prevail.  
 
Section 440. 160  Incorporation by Reference  
 
a) Each bus body and chassis must conform to the applicable provisions of the 
Federal Motor Vehicle Safety Standards (FMVSS) (49 CFR 571.1 through 
571.404).  Those applicable provisions of the FMVSS are incorporated by      ILLINOIS REGISTER             10758

 reference as that part of the FMVSS was in effect on October 1, 2007 .  No later 
amendments to or editions of 49 CFR 571 are incorporated.  
 
b) Each bus body and chassis must conform to the applicable provisions of 49 CFR 
567, Certification, and 49 CFR 568, Vehi cles Manufactured in Two or More 
Stages, that were in effect on the first day of the month in which the chassis 
manufacturer completed the last manufacturing operation on the incomplete bus.  
Those applicable provisions are incorporated by reference as the y were in effect 
on October 1, 2007 .  No later amendments to or editions of 49 CFR 567 and 49 
CFR 568 are incorporated.

Practices of the Society of Automotive Engineers Handbook  (Society of 
Automotive Engineers, Inc., 400 Commonwealth Drive, Warrendale PA 15096 -
0001, (724)776 -4841) .  Those applicable provisions of the SAE Standards and 
Recommended Practices are incorporated by reference as of the 2005 edition date.  
No later amendm ents to or editions of the SAE Standards and Recommended 
Practices are incorporated.

AGENCY NOTE:  As mandated by the United States Environmental 
Protection Agency (USEPA), diesel -powered engines manufactured after 
December 31, 2006 are re quired to meet stricter standards that will reduce 
emissions of particulate matter and nitrogen oxides into the atmosphere.  
School bus manufacturers may be required to modify exhaust systems to 
meet the USEPA requirements, e.g., mufflers may be replaced w ith after -
treatment devices that significantly reduce toxins released into the 
atmosphere.  Modifications to exhaust systems made in compliance with      ILLINOIS REGISTER             1079 4

engine) from the components listed in this subsection (j)(2).  
 
3) The tail pipe shall be extended to exit the exhaust gases either to the right 
or left side, or rear of the bus, except for prohibited zones as shown in 
Illustra tion C of this Part.  
 
4) The tail pipe shall extend out to but not more than 1 inch (25.4 mm)

defined in Section 440.220, the tail pipe may meet the chassis 
manufacturer's standard configuration.  However, the tail pipe shall not 
exit beneath any fuel filler location or beneath any emergency exit door.  
 
k) Frame.  See Section 440.420(z)(1) of this Part.  
 
l) Generating System.  The generating system may utilize either mechanical 
rectification (commutator type) or diode rectification (alternator type).  
 
1) The generator output s hall be regulated automatically so as to provide for 
efficient battery charging without causing damaging potentials or currents 
in any part of the electrical system.  Automatic means shall be provided to 
prevent battery discharge through the generator whil e the generator is not
