                                  TITLE  49
                                MOTOR VEHICLES
                                  CHAPTER 10
                      WEIGHT, SPEED AND TIRE REGULATIONS
    49-1002.  ALLOWABLE LOAD PER INCH WIDTH OF TIRE. (1) The maximum allowable
load for any vehicle tire operated on any public highway shall not exceed six
hundred (600) pounds per inch width of tire and shall not exceed the
manufacturer's load rating, whichever is less. Single tires are prohibited on
single axles or within groups of axles except for steering axles,
self-steering variable load suspension axles or when equipped with wide-base
tires fifteen (15) inches wide or greater. The width of a tire shall be
determined by the manufacturer's description marked on the sidewall of the
tire. Tires on vehicles manufactured prior to July 1, 1987, may exceed the six
hundred (600) pounds per inch width of tire limit subject to a maximum of
eight hundred (800) pounds per inch width of tire. This section shall not
apply to nonreducible overweight and/or oversize vehicles and/or loads as
authorized under section 49-1004, Idaho Code.
    (2)  Except as provided herein, no vehicle or combination of vehicles may
proceed past the place of weighing at temporary or permanent ports of entry or
checking stations when the weight carried on a single tire, as determined by
dividing the weight carried on an axle or group of axles by the number of
wheels on the axle or group of axles, exceeds on a single axle the allowable
weight above by two thousand (2,000) pounds or more or the weight of a
combination of axles exceeds the allowable weight above by seven percent (7%)
or more. Vehicles or combinations of vehicles which exceed the weight
limitations set forth herein shall be required to be brought into compliance
with the applicable weight per inch width of tire contained within this
subsection prior to continuing except those vehicles or combinations of
vehicles which are transporting loads which, in the determination of the board
or other proper authorities in charge of or having jurisdiction over a
highway, are deemed unsafe or impractical to bring into compliance at the
place of weighing. Vehicles or combinations of vehicles transporting loads in
this latter category shall obtain a travel authorization to the nearest place
of safe unloading, load adjustment or other means of legalization.
    (a)  Neither the state of Idaho or its employees, nor any authority and
    its employees in charge of or having jurisdiction over a highway, shall be
    held liable for personal injury or property damage resulting from the
    requirements of section 49-1001(8), Idaho Code.
    (b)  The fee for a travel authorization as set forth above shall be fifty
    dollars ($50.00) and shall be on a form prescribed by the board or other
    proper authorities.
    (c)  The board or other proper authorities in charge of or having
    jurisdiction over a highway shall adopt and enforce administrative rules
    as may be necessary to carry out the provisions of this section.
