67 Pa. Code § 179.16
(a) General rule. A violation of this chapter or a permit shall be authority for the officer to confiscate the permit and for imposition of any or all of the following penalties:
(b) Determination of amount of overweight.
(1) Weight in excess of permitted weight. If a vehicle or combination operating under a permit is found to have a weight in excess of the permitted axle or gross weight, the amount of overweight is determined by subtracting from the actual weight the greater of the permitted weight or the maximum weight authorized by Chapter 49, Subchapter C of the act (relating to maximum weights of vehicles).
| Example 1 (Legal axle exceeds permit axle) | |||
| Scale Weight | 16,000 | 16,000 | (Scale Weight) |
| Permit Weight | 14,000 | -18,000 | (Greater Weight = Legal) |
| Legal Weight | 18,000 | - 2,000 | (No Fine) |
| Example 2 (Permit axle exceeds legal axle) | |||
| Scale Weight | 26,000 | 26,000 | (Scale Weight) |
| Permit Weight | 24,000 | -24,000 | (Greater Weight = Permit) |
| Legal Weight | 18,000 | + 2,000 | (Amount Overweight) |
| Example 3 (Legal gross exceeds permit gross) | |||
| Scale Weight | 90,000 | 90,000 | (Scale Weight) |
| Permit Weight | 75,000 | -80,000 | (Greater Weight = Legal) |
| Legal Weight | 80,000 | +10,000 | (Amount Overweight) |
| Example 4 (Permit gross exceeds legal gross) | |||
| Scale Weight | 90,000 | 90,000 | (Scale Weight) |
| Permit Weight | 84,000 | -84,000 | (Greater Weight = Permit) |
| Legal Weight | 80,000 | + 6,000 | (Amount Overweight) |
The provisions of this § 179.16 adopted August 5, 1977, effective August 6, 1977, 7 Pa.B. 2192; amended April 25, 1980, effective May 1, 1980, 10 Pa.B. 1686; renumbered May 16, 1981, 11 Pa.B. 1678; amended January 20, 1984, effective March 21, 1984, 14 Pa.B. 224; readopted December 2, 1988, effective December 3, 1988, 18 Pa.B. 5364. Immediately preceding text appears at serial pages (125309) to (125310).
The fines assessed under the Vehicle Code for operating overweight vehicles without a permit were not proper when special permits had been obtained. Commonwealth v. J. F. Lomma, Inc., 590 A.2d 342 (Pa. Super. 1991).
Where a party has an overweight permit authorizing the party to haul overweight loads over a specific route, a penalty imposed on that party’s hauling of an overweight load over an unauthorized route shall be imposed under 75 Pa.C.S. § 4945, not under 75 Pa.C.S. § 4907. Commonwealth v. Liver, 520 A.2d 56 (Pa. Super. 1987).
An initial administrative review by the Department of Transportation is not required under this section, which clearly states that the violation of any regulation under the Vehicle Code would invalidate the special permit and constitute grounds for prosecution. Austin v. Commonwealth, 442 A.2d 832 (Pa. Cmwlth. 1982). Vacated on other grounds see 459 A.2d 336 (Pa. 1983).
