52 Pa. Code § 31.12
Common carriers by motor vehicle, contract carriers by motor vehicle and forwarders shall comply with all applicable provisions of the act not specifically referred to in this chapter. Failure to comply with this chapter or the terms and conditions of the certificates of public convenience or permit issued will be sufficient cause for the Commission to suspend, revoke or rescind the rights and privileges conferred by the certificate of public convenience or permit and to invoke a forfeiture or other penalty provisions of the act. No revocation or penalty will be finally ordered until the common carrier, contract carrier or forwarder has first been given opportunity to be heard as to why the certificate permit should not be revoked or penalty imposed.
