(a) General information.
  (1) Permits issued under this section are subject to the requirements of §219.61 of this title (relating to General Requirements for Permits for Oversize and Overweight Unladen Lift Equipment Motor Vehicles).
  (2) A quarterly hubometer permit:
    (A) is effective for three consecutive months;
    (B) allows the unladen lift equipment motor vehicle to travel on all state-maintained highways; and
    (C) allows the unladen lift equipment motor vehicle to travel on a state-wide basis.
  (3) An unladen lift equipment motor vehicle permitted under this section must not exceed any of the following dimensions:
    (A) 12 feet in width;
    (B) 14 feet, 6 inches in height; or
    (C) 95 feet in length.
  (4) With the exception of unladen lift equipment motor vehicles that are overlength only, unladen lift equipment motor vehicles operated with a quarterly hubometer permit must be equipped with a hubometer. The permittee must maintain the hubometer in good working condition.
  (5) An unladen lift equipment motor vehicle exceeding 175,000 pounds gross weight must:
    (A) have front and rear escort flag vehicles to prevent traffic from traveling beside the unladen lift equipment motor vehicle as it crosses a bridge;
    (B) cross all multi-lane bridges by centering the unladen lift equipment motor vehicle 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.
  (6) The permitted unladen lift equipment motor vehicle must not cross a load-restricted bridge when exceeding the posted capacity of the bridge.
  (7) The permit may be amended only to change the following:
    (A) if listed on the permit, the hubometer serial number; or
    (B) the license plate number.
(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 an unladen lift equipment motor vehicle will be determined by calculating the "W" weight for the group, using the formulas in Figure 2: 43 TAC §219.62(f), "Maximum Permit Weight Formulas," and comparing the calculated "W" weight with the corresponding "W" weight that is established in Figure 1: 43 TAC §219.62(f), "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) An unladen lift equipment motor vehicle that has any group of axles that exceeds the limits established by Figure 1: 43 TAC §219.62(f), "Maximum Permit Weight Table," and Figure 2: 43 TAC §219.62(f), "Maximum Permit Weight Formulas," is not eligible for a permit under this section; however, it is eligible for a permit under §219.62 of this title (relating to Single-Trip Mileage Permits).
(c) Initial permit application and issuance.
  (1) An application for an initial quarterly hubometer permit must be made in accordance with §219.61(b) of this title. In addition, the applicant must provide the current hubometer mileage reading and an initial $31 processing fee.
  (2) Upon verification of the unladen lift equipment motor vehicle information and receipt of the permit fee, the department will provide a copy of the permit to the applicant, and will also provide a renewal application form to the applicant.
(d) Permit renewals and closeouts.
  (1) An application for a permit renewal or closeout must be made on a form and in a manner prescribed by the department.
  (2) Upon receipt of the renewal application, the department will verify the unladen lift equipment motor vehicle information, check mileage traveled on the last permit, calculate the new permit fee, and advise the applicant of the permit fee.
(e) Permit fees.
  (1) Minimum fee. The minimum fee for a quarterly hubometer permit is either the calculated permit fee or $31, whichever is the greater amount.
  (2) Fees for overlength unladen lift equipment motor vehicles. An unladen lift equipment motor vehicle that is overlength only is not required to have a hubometer. The fee for this permit is $31.
  (3) Quarterly hubometer permit fee calculation. The permit fee for a quarterly hubometer permit is calculated by multiplying the hubometer mileage, the highway use factor, and the total rate per mile, and then adding the indirect cost share to the product.
    (A) Hubometer mileage. Mileage for a quarterly hubometer permit is determined by the unladen lift equipment motor vehicle's current hubometer mileage reading minus the unladen lift equipment motor vehicle's hubometer mileage reading from the previous quarterly hubometer permit.
    (B) Highway use factor. The highway use factor for a quarterly hubometer permit is 0.3.
    (C) Total rate per mile. The total rate per mile is the combined mileage rates for width, height, and weight for the unladen lift equipment motor vehicle.
      (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.
