The law does not distinguish between people who are Pennsylvania residents and people who are residents of other States. This means that you will face the same penalties as a Pennsylvania resident would. A conviction for a DUI can carry a mandatory jail sentence, a mandatory fine, and a mandatory license suspension. If you are sentenced to jail you will have to serve that jail time here in Pennsylvania. In addition, because you are not from Pennsylvania you may not be eligible for most of the programs that Pennsylvania offers as alternatives to jail time because they will have difficulty supervising you from another state.
If you are convicted of a DUI in Pennsylvania, Pennsylvania cannot suspend your out of state license. They will, however, suspend your driving privileges in the state of Pennsylvania. The Pennsylvania Department of Transportation will send you your suspension information telling you to turn PA your driver’s license into them. Since you do not have a PA license you need to fill out a PennDOT form that says, “I acknowledge my suspension in the state of Pennsylvania” and state on that form that you are not licensed in Pennsylvania. You will then send this form into PennDOT instead of your driver’s license. PennDOT will hold on to that form until your suspension is up. You will also have to pay a restoration fee and complete any other requirements that are in the suspension information that PennDOT sent to you. Once everything is complete PennDOT will restore your driving privileges in the state of Pennsylvania. The big catch here is if the state where your license is issued from finds out about the suspension in the state of Pennsylvania through reciprocity. If your home state has reciprocity with PA, your home state would be made aware of the PA suspension and they could also suspend your license. The state that issued you your license can suspend your license for an offense that you committed in the state of Pennsylvania. The length of that suspension is dependent on the laws in that state. Your license could be suspended for the same amount of time as Pennsylvania or they could suspend you for a longer period depending on their laws.
