A conviction for many traffic offenses can result in a suspension of driving privilege.
A person can also be suspended for a DUI violation. For some, this leads to suspension time of many months or years. PennDOT previously took the position that credit toward the suspension time only started when you surrendered a driver’s license or submitted an acknowledgment of suspension if you didn't have a license.
The law has changed! You may be able to be restored even though you never acknowledged suspension notices.
