(a) No person shall operate
upon a highway a first division vehicle which has
a clearance between the frame and ground in excess of 22 inches. The
lowest portion of the body floor shall not be more than 4 inches above the
top of the frame. No such vehicle shall be modified to cause the vehicle
body or chassis to come in contact with the ground, expose the fuel tank to

under normal operation.
(b) No person shall operate upon a highway a second division vehicle
which has a clearance between the frame and ground
which is in excess of the limits specified within this subsection for its

GVWR means the manufacturer's gross vehicle weight rating whether or not
the vehicle is modified by the use of parts not originally
installed by the manufacturer. The stacking or attaching of vehicle frames
(one frame on top of or beneath another frame) is prohibited. No portion of
the body floor shall be
raised above the frame.

be made when a vehicle is unladen on a
level surface at the lowest point from the bottom of the original vehicle
longitudinal frame rail between the front axle and second axle
on the vehicle.
(d) This Section does not apply to specially designed or modified
motor vehicles when operated off the highways. Such motor vehicles may be
transported upon the highway only by use of a trailer or semitrailer. The
specially designed or modified motor vehicle may also be transported upon
another vehicle, providing that the entire weight of the specifically
designed or modified vehicle is resting upon the transporting vehicle.
(e) Any violation of this Section is a Class C misdemeanor. A second
conviction under this Section shall be punished with a fine of not less
than $500. An officer making an arrest under this Section shall order the
vehicle driver to remove the vehicle from the highway. A person convicted
under this Section shall be ordered to bring his vehicle into compliance
with this Section.
