| (a) General information.
(1) Permits issued under this section are subject to
the requirements of §219.41 of this title (relating to General
Requirements).
(2) A single-trip mileage permit:
(A) is limited to a maximum of seven consecutive days;
(B) routes the vehicle from the point of origin to
the point of destination and has the route listed on the permit; and
(C) allows the unit to be returned to the point of
origin on the same permit, provided the return trip is made within
the time period stated in the permit.
(3) A unit exceeding 175,000 pounds gross weight must:
(A) have front and rear escort flag vehicles to prevent
traffic from traveling beside the unit as it crosses a bridge;
(B) cross all multi-lane bridges by centering the unit
on a lane line;
(C) cross all two-lane bridges in the center of the
bridge; and
(D) cross each bridge at a speed not greater than 20
miles per hour.
(4) A unit exceeding 12 feet in width must be centered
in the outside traffic lane of any highway that has paved shoulders.
(b) Maximum permit weight limits.
(1) The maximum permit weight for any single axle must
not exceed 30,000 pounds or 850 pounds per inch of tire width, whichever
is less.
(2) The maximum permit weight for any group of axles
on a unit will be determined by calculating the "W" weight for the
group, using the formulas shown in Figure 2: 43 TAC §219.42(f),
titled "Maximum Permit Weight Formulas," and comparing the calculated
"W" weight with the corresponding "W" weight that is established in
Figure 1: 43 TAC §219.42(f), titled "Maximum Permit Weight Table."
(3) The maximum permit weight per inch of tire width
for axles that are steerable must not exceed 950 pounds, and the maximum
permit weight per inch of tire width for axles that are not steerable
must not exceed 850 pounds.
(4) A unit that does not have any group of axles that
exceeds the limits established in Figure 1: 43 TAC §219.42(f),
"Maximum Permit Weight Table," and Figure 2: 43 TAC §219.42(f),
"Maximum Permit Weight Formulas" will be permitted with a single-trip
mileage or quarterly hubometer permit for travel on any route that
does not include a load restricted bridge.
(5) A unit that has any group of axles that exceeds
the limits established by Figure 1: 43 TAC §219.42(f), "Maximum
Permit Weight Table," and Figure 2: 43 TAC §219.42(f), "Maximum
Permit Weight Formulas" will be eligible, on an individual case-by-case
basis, for a single-trip mileage permit only; permit approval or denial
will be based on a detailed route study and an analysis conducted
by TxDOT of each bridge on the proposed travel route to determine
if the road(s) and bridge(s) are capable of sustaining the movement.
(6) A road or bridge that has been analyzed and determined
to be incapable of sustaining the unit will be excluded from the permit
route.
(c) Permit application and issuance.
(1) An application for a single-trip mileage permit
under this section must be made in accordance with §219.41(b)
of this title and shall also include the origin and destination points
of the unit.
(2) Upon receipt of the application, the department
will review and verify unit size and weight information, check route
and mileage to be traveled, compute the permit fee, and advise the
applicant of the permit fee.
(3) Upon receipt of the permit fee, the department
will advise the applicant of the permit number, and will provide a
copy of the permit to the applicant.
(d) Permit fees and refunds.
(1) Minimum fee. The minimum fee for a single-trip
mileage permit is either the calculated permit fee or $31, whichever
is the greater amount.
(2) Permit fee calculation. The fee for a single-trip
mileage permit is calculated by multiplying the number of miles traveled,
the highway use factor, and the total rate per mile, and then adding
the indirect cost share to the product.
(A) Highway use factor. The highway use factor for
a single trip mileage permit is 0.6.
(B) Total rate per mile. The total rate per mile is
the combined mileage rates for width, height, and weight for the unit.
For a trailer mounted unit, the total rate per mile is based on the
overall width, overall height, and all axle weights, including the
truck-tractor axles.
(i) The mileage rate for width is $.06 per mile for
each foot (or fraction thereof) above legal width.
(ii) The mileage rate for height is $.04 per mile for
each foot (or fraction thereof) above legal height.
(iii) The mileage rate for a single axle or any axle
within a group that exceeds 20,000 pounds, but is less than or equal
to 25,000 pounds, is calculated by multiplying $.045 times the amount
by which the axle or axle group weight exceeds the legal weight for
the axle or axle group and dividing the resultant figure by 1,000
pounds.
(iv) The mileage rate for a single axle or any axle
within a group that exceeds 25,000 pounds, but is less than or equal
to 30,000 pounds, is calculated by multiplying $.055 times the amount
by which the axle or axle group weight exceeds the legal weight for
the axle or axle group and dividing the resultant figure by 1,000
pounds.
(3) Permit fees for trailer mounted units.
(A) The permit fee for a trailer mounted unit is based
on the overall width, overall height, and all axle weights, including
the truck-tractor axles.
(B) A unit with two or more axle groups that do not
have a spacing of at least 12 feet between the closest axles of the
opposing groups must have the permit fee calculated by the following
method.
(i) The axle group with the lowest weight will have
the axle closest to the next axle group temporarily disregarded from
its group in order to create a spacing of at least 12 feet between
the two groups for fee calculation purposes.
(ii) An axle group will not have more than one axle
disregarded.
(iii) The permit fee for the axle group with the temporarily
disregarded axle must be based on the actual weight of the entire
axle group minus the legal weight for the remaining axles of the group.
(4) Refunds. Fees for permits issued under this section
are non-refundable.
(e) Amendments. A single-trip mileage permit may not
be amended unless an exception is granted by the department.
(f) Weight table and formulas. The following table
entitled "Maximum Permit Weight Table" is Figure 1: 43 TAC §219.42(f),
and the list of formulas entitled, "Maximum Permit Weight Formulas,"
is Figure 2: 43 TAC §219.42(f).
