A DUI conviction from another state will not show up on a standard Pennsylvania Criminal History check. However, that conviction will show up on a nationwide criminal history check. When the Police search your criminal history, they can access criminal records from other states by using your name, birth date, social security number, and other identifying information which might be associated with your criminal history.
The Police can, and most often do, search for driving records in other states. A conviction from another state for a DUI will usually also show up on that State’s driving record, as most DUI convictions require some type of driver’s license suspension. Whether a DUI conviction from another State shows up on your Pennsylvania Driving Record depends on several factors, including whether this is your first DUI offense. As of 2020, if you are convicted of a DUI in another state, PennDOT will not take any action on your license if that out of state conviction is the first DUI conviction that you have ever received.
