DOT marking identification - Pennsylvania
Pennsylvania has adopted 390.21 of the Federal Motor Carrier Safety Regulations (FMCSRs) for intrastate operations.
The Pennsylvania Department of Transportation (PennDOT) adoption of 390.21 applies to a vehicle or combination of vehicles used on a highway in intrastate commerce with a gross vehicle weight rating or gross combination weight rating, or gross vehicle weight or gross combination weight of 17,001 pounds or more (whichever is greater) or transporting hazardous materials which are required to be placarded.
| Public Utility Commission (PUC) Regulated | Intrastate vehicles required to obtain intrastate operating authority from the Public Utility Commission (PUC) are subject to the following vehicle identification requirements. Every for-hire common or contract motor vehicle must be marked on each side, in letters at least two inches high, and at least 1/2-inch wide, the name and address of the motor carrier and the number of the certificate of public convenience or permit as follows: “PA. P.U.C. NO. A__ . ” If the certificate of a common carrier or permit of a contract carrier is canceled or revoked by the PUC or when a motor vehicle is permanently removed from service, the carrier must immediately remove the certificate or permit number from the vehicle. If the vehicle is owned by someone other than the motor carrier operating it, both sides of the vehicle must display, in letters at least two inches high and at least 1/2-inch wide the wording: “OPERATED BY (name and address of authorized motor carrier), PA. P.U.C. NO. A___.” If a removable device is used to identify the operating carrier as lessee, the device must be of durable material and securely affixed to the vehicle operated throughout the duration of the lease. Upon relinquishing possession of the equipment, the motor carrier operating the leased vehicle under this section must remove the legend or removable device displayed on the vehicle showing it to be the operating carrier. |
