Q. Does anyone know if the look back period for a DUI in PA is from arrest date to next arrest date or from conviction date to conviction date?

A. The DUI look back is from the date of the conviction to the date of the new arrest. The look back period is 10 years. If you have made 10 years, your recent DUI will be considered a first DUI, for the purposes of sentencing. You also may qualify for Accelerated Rehabilitative Disposition, otherwise ARD, a first offender’s program, if there is nothing else precluding you from the program. There are exceptions. Be aware of bumped-up license suspension periods for higher blood alcohol content, drugs in your blood system, accidents or being a minor.
