(B) Flammable gas powered vehicles, machines or equipment, which
have cylinders (fuel tanks) that are equipped with electrically
operated valves, may be transported under the following conditions:
    (1) The valves must be in the closed position and in the case of
electrically operated valves, power to those valves must be
disconnected;
    (2) After closing the valves, the vehicle, equipment or machinery
must be operated until it stops from lack of fuel before being loaded
aboard the aircraft;
    (3) In no part of the closed system shall the pressure exceed 5% of
the maximum allowable working pressure of the system or 290 psig (2000
kPa), whichever is less; and
    (4) There must not be any residual liquefied gas in the system,
including the fuel tank.
    (3) Truck bodies or trailers on flat cars--flammable liquid or gas
powered. Truck bodies or trailers with automatic heating or
refrigerating equipment of the flammable liquid type may be shipped
with fuel tanks filled and equipment operating or inoperative, when
used for the transportation of other freight and loaded on flat cars as
part of a joint rail and highway movement, provided the equipment and
fuel supply conform to the requirements of Sec.  177.834(l) of this
subchapter.
    (4) Modal exceptions. Quantities of flammable liquid fuel greater
than 500 mL (17 ounces) may remain in the fuel tank in self-propelled
vehicles engines, and machinery only under the following conditions:
    (i) For transportation by motor vehicle or rail car, the fuel tanks
must be securely closed.
    (ii) For transportation by vessel, the shipment must conform to
Sec.  176.905 of this subchapter for self-propelled vehicles and Sec.
176.906 of this subchapter for engines and machinery.
    (iii) For transportation by aircraft, when carried in aircraft
designed or modified for vehicle ferry operations when all the
following conditions must be met:
    (A) Authorization for this type operation has been given by the
appropriate authority in the government of the country in which the
aircraft is registered;
    (B) Each vehicle is secured in an upright position;
    (C) Each fuel tank is filled in a manner and only to a degree that
will preclude spillage of fuel during loading, unloading, and
transportation; and
    (D) Each area or compartment in which a self-propelled vehicle is
being transported is suitably ventilated to prevent the accumulation of
fuel vapors.
    (c) Battery-powered or installed. Batteries must be securely
installed, and wet batteries must be fastened in an upright position.
Batteries must be protected against a dangerous evolution of heat,
short circuits, and damage to terminals in conformance with Sec.
173.159(a) and leakage; or must be removed and packaged separately
under Sec.  173.159. Battery-powered vehicles, machinery or equipment
including battery-powered wheelchairs and mobility aids are not subject
to any other requirements of this subchapter except Sec.  173.21 when
transported by rail, highway or vessel. Where a vehicle could possibly
be handled in other than an upright position, the vehicle must be
secured in a strong, rigid outer packaging. The vehicle must be secured
by means capable of restraining the vehicle in the outer packaging to
prevent any movement during transport which would change the
orientation or cause the vehicle to be damaged.
    (d) Lithium batteries. Except as provided in Sec.  172.102, special
provision A101, of this subchapter, vehicles, engines, and machinery
powered by lithium metal batteries, that are transported with these
batteries installed, are forbidden aboard passenger-carrying aircraft.
Lithium batteries contained in vehicles, engines, or mechanical
equipment must be securely fastened in the battery holder of the
vehicle, engine, or mechanical equipment, and be protected in such a
manner as to prevent damage and short circuits (e.g., by the use of
non-conductive caps that cover the terminals entirely). Except for
vehicles, engines, or machinery transported by highway, rail, or vessel
with prototype or low production lithium batteries securely installed,
each lithium battery must be of a type that has successfully passed
each test in the UN Manual of Tests and Criteria (IBR, see Sec.  171.7
of this subchapter), as specified in Sec.  173.185, unless approved by
the Associate Administrator. Where a vehicle could possibly be handled
in other than an upright position, the vehicle must be secured in a
strong, rigid outer packaging. The vehicle must be secured by means
capable of restraining the vehicle in the outer packaging to prevent
any movement during transport which would change the orientation or
cause the vehicle to be damaged.
    (e) Fuel cells. A fuel cell must be secured and protected in a
manner to prevent damage to the fuel cell. Equipment (other than
vehicles, engines or mechanical equipment) such as consumer electronic
devices containing fuel cells (fuel cell cartridges) must be described
as ``Fuel cell cartridges contained in equipment'' and transported in
accordance with Sec.  173.230. Where a vehicle could possibly be
handled in other than an upright position, the vehicle must be secured
in a strong, rigid outer packaging. The vehicle must be secured by
means capable of restraining the vehicle in the outer packaging to

prevent any movement during transport which would change the
orientation or cause the vehicle to be damaged.
    (f) Other hazardous materials. (1) Items containing hazardous
materials, such as fire extinguishers, compressed gas accumulators,
safety devices, and other hazardous materials that are integral
components of the motor vehicle, engine, or mechanical equipment, and
that are necessary for the operation of the vehicle, engine, or
mechanical equipment, or for the safety of its operator or passengers,
must be securely installed in the motor vehicle, engine, or mechanical
equipment. Such items are not otherwise subject to the requirements of
this subchapter. Equipment (other than vehicles, engines, or mechanical
equipment), such as consumer electronic devices containing lithium
batteries, must be described as ``Lithium metal batteries contained in
equipment'' or ``Lithium ion batteries contained in equipment,'' as
appropriate, and transported in accordance with Sec.  173.185, and
applicable special provisions. Equipment (other than vehicles, engines,
or mechanical equipment), such as consumer electronic devices
containing fuel cells (fuel cell cartridges), must be described as
``Fuel cell cartridges contained in equipment'' and transported in
accordance with Sec.  173.230.
    (2) Other hazardous materials must be packaged and transported in
accordance with the requirements of this subchapter.
    (g) Additional requirements for internal combustion engines and
vehicles with certain electronic equipment when transported by aircraft
or vessel. When an internal combustion engine that is not installed in
a vehicle or equipment is offered for transportation by aircraft or
vessel, all fuel, coolant or hydraulic systems remaining in the engine
must be drained as far as practicable, and all disconnected fluid pipes
that previously contained fluid must be sealed with leak-proof caps
that are positively retained. When offered for transportation by
aircraft, vehicles equipped with theft-protection devices, installed
radio communications equipment or navigational systems must have such
devices, equipment or systems disabled.
    (h) Exceptions. Except as provided in paragraph (f)(2) of this
