(a)
General rule. Except as provided in subsection (h), a vehicle
or combination carrying metal cargo or logs shall be equipped with a front-end
structure or similar device of sufficient strength to prevent load shifting,
and penetration or crushing of the compartment of the driver.
(b)
Location. The front-end
structure shall be located between the metal cargo or logs of the vehicle and
the driver of the vehicle.
(c)
Height. A front-end structure shall extend to the height of
the passenger compartment of the vehicle or to a height at which it blocks
forward movement of any metal cargo or logs being carried on the vehicle,
whichever is less.
(d)
Width. The front-end structure shall have a width which is at
least equal to the width of the vehicle or which blocks forward movement of an
item of cargo being transported on the vehicle, whichever is less.
(e)
Strength. A front-end
structure and the manner in which it is attached shall be capable of
withstanding at least the horizontal forward static load indicated below:
(1) A front-end structure less than 6 feet in
height: a horizontal forward static load equal to 1/2 of the weight of the
metal cargo or logs being transported on the vehicle uniformly distributed over
the entire portion of the front-end structure that is at or below the height of
the passenger compartment or a height above the floor of the vehicle at which
it blocks forward movement of an item of the metal cargo or logs of the
vehicle, whichever is less.
(2) A
front-end structure 6 feet in height or higher: a horizontal forward static
load equal to .4 of the weight of the metal cargo or logs being transported on
the vehicle uniformly distributed over the entire front-end
structure.
(f)
Penetration resistance. The front-end structure shall be
designed, constructed and maintained so that it is capable of resisting
penetration by an item of metal cargo or logs that contacts it when the vehicle
decelerates at a rate of 20 feet per second. The front-end structure may have
no aperture large enough to permit an item of cargo or log in contact with the
structure to pass through it.
(g)
Substitute devices. The requirements of this section may be
met by the use of devices performing the same functions as a front-end
structure, if the devices are at least as strong as and provide protection
against shifting metal cargo or logs at least equal to a front-end structure
which conforms with these requirements.
(h)

requirements of this section does not apply to the following vehicles:
(1) A trailer being towed by a vehicle that
is equipped with a front-end structure that conforms with the requirements of
