After more than six years, weight class stickers are no longer required, effective upon publication in the Pennsylvania Bulletin January 29, 2022.

PMTA gladly welcomes this change after opposing the regulation for many years. 

From the Bulletin:

The Department of Transportation (Department), under the authority of 75 Pa.C.S. § 6103 (relating to promulgation of rules and regulations by department) and more generally 75 Pa.C.S. §§ 1301 and 1304(b) (relating to registration and certificate of title required; and registration criteria), deletes Chapter 55 (relating to registration class stickers) to read as set forth in Annex A.

Purpose of Chapter

 This chapter implements 75 Pa.C.S. § 1304(b) regarding the classification of vehicles. Section 1304(b) of 75 Pa.C.S. authorizes the Department to ''identify vehicles by type as to weight, design, loading, use, ownership or other significant characteristics for purposes of registration.'' The Department adopted Chapter 55 in 1979 to implement the portion of section 1304(b) that concerns identifying vehicle according to weight for purposes of registration. Chapter 55 requires the affixation of a registration class sticker (Registration Class Sticker) to a windshield, which indicates the registered gross weight class of a truck, truck-tractor or combination registered in this Commonwealth in the registered gross weight classes 2 through 25.
