lieu of a mechanical lift if the ramp meets all the requirements of the
Americans with Disability Act (ADA) as found in 36 CFR 1192.23(c) Vehicle
ramp.
(2) A ramp device which does
not meet the specifications of ADA but does meet the specifications of
paragraph C3 of this section may be installed and used, when, and only when a
power lift system is not adequate to load and unload students having special
and unique needs. A readily accessible ramp my also be installed for emergency
exit use. If stowed in the passenger compartment, the ramp must be properly
secured and located away from general passenger contact. It must not obstruct
or restrict any aisle or exit while in its stowed or deployed
position.

(3) The inside height of the wheel housing
above the floor line shall not exceed 12-inches.
(4) The wheel housing shall provide clearance
for installation and use of tire chains on single and dual (if so equipped)
power-driving wheels.
(5) No part
of a raised wheel housing shall extend into the emergency door
opening.
HHH.
WINDOWS
(1) Each full side window,
other than emergency exits designated to comply with
49
CFR 571.217(FMVSS), shall
provide an unobstructed emergency opening of at least 9-inches but not more
than 13-inches high and 22-inches wide, obtained by lowering window. One side
window on each side of the bus may be less than 22-inches wide.
(2) Glazing shall be installed in all doors,
windows, and windshields consistent with federal and state motor vehicle
code.
(3) The driver's side windows
shall consists of transition glass when manufacturing technology becomes
available that darkens in daylight conditions and clears in dark conditions
consistent with the glazing standard.
III.
WINDSHIELD: Option - A
multi-piece windshield shall be provided.
JJJ.
WINDSHIELD WIPERS
(1) A windshield wiping system, two-speed or
variable speed, with an intermittent feature, shall be provided. A windshield
washer system shall be provided.
(2) The wipers shall be operated by one or
more air or electric motors of sufficient power to operate wipers. If one motor
is used, the wipers shall work in tandem to give full sweep of windshield to
allow for full visibility of the driver view and outside mirrors.
KKK.
WIRING
(1) All wiring shall conform to current SAE
requirements.
(2) Circuits: Two (2)
additional circuits shall be provided for a two-way radio communication system
and video camera surveillance equipment.
(a)
Wiring shall be arranged in circuits, as required, with each circuit protected
by a fuse or circuit breaker. A system of color and number coding shall be used
and an appropriate identifying diagram shall be provided to the end user along
with the wiring diagram provided by the chassis manufacturer. The wiring
diagrams shall be specific to the bus model supplied and include any changes to
wiring made by the body manufacturer. Chassis wiring diagrams shall also be
supplied to the end user. A system of color and number coding shall be used on
buses. The following body interconnecting circuits shall be color coded as
noted: The color of cables shall correspond to SAE J 1128.

shall be coded by number or letter on a diagram of circuits and shall be
attached to the body in a readily accessible location.
(3) The entire electrical system of the body
shall be designed for the same voltage as the chassis on which the body is
mounted.
(4) All wiring shall have
an amperage capacity exceeding the design load by at least 25%. All wiring
splices are to be done at an accessible location and noted as splices on wiring
diagram.
(5) A body wiring diagram,
of a size which can be easily read, shall be furnished with each bus body or
affixed in an area convenient to the electrical accessory control
panel.
(6) The body power wire
shall be attached to a special terminal on the chassis.
(7) All wires passing through metal openings
shall be protected by a grommet.
(8) Wires not enclosed within body shall be
fastened securely at intervals of not more than 18-inches. All joints shall be
soldered or joined by equally effective connectors, which shall be
water-resistant and corrosion-resistant.
