Current through Register Vol. 48, No. 28, July 12, 2024
a) UNDERCOATING
PROCEDURES/SPECIFICATIONS:
Fire resistant undercoating material applied by spray.
						  Entire underside of body, front fenders, floor members and side panels below
						  floor level must be covered.
REJECT VEHICLE IF:
Undercoating does not meet requirements.
b) VENTILATION
PROCEDURES/SPECIFICATIONS:
Body must be equipped with ventilating system capable
						  of supplying proper quantity of air under operating conditions.
REJECT VEHICLE IF:
Air is obstructed; not securely fastened; not
						  covered.
c) WARNING DEVICES
PROCEDURES/SPECIFICATIONS:
Either three red cloth flags not less than 1/2 inches
						  square and three red reflectors minimum of 3 inches in diameter or three
						  bi-directional emergency triangles that conform to
						  49 CFR
						  571.125. (Section 12-702 of the Illinois
						  Vehicle Equipment Law) Kit shall be securely stored.
REJECT VEHICLE IF:
Required warning devices are not present or are in poor
						  condition.
d) WHEELS
1) Housings
PROCEDURES/SPECIFICATIONS:
Full open type attached to floor sheet to prevent
						  water, fumes or dust entering the body. Inside height should not exceed 10
						  inches above floor line. Housings shall allow for unimpeded wheel and tire
						  service or removal. Housing shall provide clearance for installation and use of
						  tire chains on the dual or single tires installed on the rear wheels.
Inspect tire and road wheel assesmblies.
REJECT VEHICLE IF:
Wheel housings do not meet clearance requirement; wheel
						  housings are not firmly secured; holes are present.
A tire or wheel is rubbing against any portion of the
						  suspension, chassis, or body.
2) Rim
PROCEDURES/SPECIFICATIONS:
Inspect all wheel and rim bolts, nuts, studs, lugs,
						  locking rings, etc. Each cover, cap, or decorative ring that obscures any of
						  these items must be removed prior to the inspection.
Inspect for visible wheel damage.
REJECT VEHICLE IF:
Any wheel or rim securing device such as a nut, bolt,
						  stud, lug, ring, or other type securing device is loose, missing, or
						  cracked.
Wheel locating hole(se) are elongated, oversized, or
						  "wallowed out." Any part of a wheel or rim is cracked, repaired by welding or
						  rewelding, or damaged so as to cause unsafe operation of the vehicle.
3) Tires
PROCEDURES/SPECIFICATIONS:
Inspect tire for proper inflation (i.e., flat
						  tire).
A regrooved, retreaded, or recapped tire shall not be
						  on the front steering axle.
A tire with restricted use marking is prohibited (e.g.,
						  "NHS" or "SL" following size marking, "Off Highway," "Farm Use," "Racing Only,"
						  etc.).
No school bus shall be equipped with any tire which has
						  been so worn that read configuration is absent on any part of the tire which is
						  in contact with the road surface.
Inspect for tread wear:
A)
Check for the presence of tread wear indicators.
B)
For tires without tread wear indicators, use tread
						  depth gauge to measure groove depth.
Steering (Front) and Drive (Rear) Axles: Measure groove
						  depth at any point on a major tread groove.
C)
For tires without tread wear indicators and with
						  noncircumferential grooves, or "spaces," between the tread elements (as in
						  snow, mud, lug knob, or traction treads).
Steering (Front) and Drive (Rear) Axles: Measure in a
						  major groove at a point halfway between the center of the tire and the outside
						  of the tread at any point on a major tread groove.
D)
Inspect tire for bald, partially bald, cupped, dished,
						  or unevenly worn areas.
E)
The measurements shall not be made where the tie bars,
						  humps, or fillets are located.
AGENCY NOTE:
"Bald" means without a groove.
Inspect for visible cord damage and exposure of ply
						  cords in sidewalls and treads, including belting material cords.
Inspect for evidence of tread or sidewall
						  separation.
Inspect for regrooved or recut treads.
AGENCY NOTE:
49 CFR 369 requires tires marked "REGROOVABLE" to have
						  sufficient tread rubber that, after regrooving, cord material below the grooves
						  shall have a protective covering of tread material at least 
						  3/32 inch
						  thick.
Inspect tires for legible markings showing size
						  designation and carcass construction.
AGENCY NOTE:
"R" in size designation shows radial construction. More
						  plies at tread than sidewall shows belted construction. Same number of plies at
						  tread and sidewall, without a belted or radial indication, shows plain bias
						  construction.
Tires on same axle must be of same construction.
Inspect tires for size designation and for matched
						  construction.
AGENCY NOTE:
"Construction" refers to bias, bias belted, or radial
						  arrangement of ply cores in the tire carcass.
Inspect each single dual tire assembly.
A mixture of regular and mud-and-snow treads must be
						  same on both sides of axle.
When radial and conventional (i.e., bias) ply tires are
						  both used on a vehicle, one of the following two requirements shall be
						  met:
i)
On vehicles with one single wheel axle and one or more
						  dual wheel axle, radial tires shall be used on the steering (i.e., front) axle
						  only.
ii)
On vehicles having two single wheel axles, radial tires
						  shall be used on the rear axle only.
A tube built only for bias tire shall not be installed
						  in a radial tire. Red color shall not be added to stem of a "bias" tube. (Valve
						  stem of tube for radial tire is either marked "radial" or has red ring or is
						  painted red.) A "radial" tube and flap may be used in a bias tire.
Inspect valve stems.
REJECT VEHICLE IF:
Improper inflation (flat tire).
Regrooved, retreaded or recapped tire is located on
						  front steering axle.
Restricted marking is present.
Any part of tire which is in contact with road surface
						  is absent of tread configuration.
i)
Tread wear indicators contact road at any point on a
						  major tread groove.
ii)
On steering (front) axle: Tread groove depth is less
						  than 
						  4/32 inch
						  when measured at any point on a major tread groove.
On drive (rear) axle: Tread groove depth is less than 
						  2/32 inch
						  when measured at any point on a major tread groove.
iii)
On steering axle: Tread groove depth is less than 
						  4/32 inch
						  when measured in a major groove at a point halfway between the center of the
						  tire and the outside of the tread at any point on a major tread groove.
On drive axle: Tread groove depth is less than 
						  2/32 inch
						  when measured in a major groove at a point halfway between the center of the
						  tire and the outside of the tread when measured at any major tread
						  groove.
iv)
The tire has bald, partially bald, cupped, dished or
						  unevenly worn areas.
A broken or cut cord can be seen. Rubber is worn,
						  cracked, cut or otherwise deteriorated or damaged so that a cord can be seen -
						  either when the tire is not touched or when the edges of the crack, cut or
						  damage are parted or lifted by hand.
Tire has bump, bulge, knot or other evidence of partial
						  carcass failure, air seepage, or loss of adhesion between carcass and tread or
						  sidewall.
Tread has been regrooved or recut on a tire that does
						  not have the word "REGROOVABLE" molded on or into both sides of the
						  tire.
A tire on a road wheel does not exhibit a legible size
						  marking and a legible construction marking.
Tires on the same axle are not of same
						  construction.
A tire exceeds the diameter (not width) of its mate by
						  1/2 inch (1/4 inch radius) or more; or one tire touches its mate.
A mixture of regular and mud-and-snow treads are not
						  the same on both sides of the axle.
Requirements for using both radial and conventional
						  tires on a vehicle are not met.
A tube built only for bias tire but installed in a
						  radial tire.
A valve stem leaks; is cracked; is either damaged or
						  positioned so as to hamper pressure checking or inflation; shows evidence of
						  wear because of misalignment.
e) WINDOWS

						  49 CFR
