The consequences per DUI offense in Pennsylvania will vary, but fundamentally, the less DUI convictions a person has, the less severe the potential penalties would be. For example, a person's first offense versus their second or third or fourth would generally result in lesser penalties. That's because with each subsequent conviction, if it's within the 10 year look-back period, for sentencing purposes, those prior convictions would result in the penalties being more severe with each subsequent conviction. It will also depend on the tier under which the DUI is being prosecuted. Tier one, tier two or tier three.
Tier one is going to result in the least severe consequences. Tier three would result in the most severe consequences. There's potential mandatory minimums that would be involved with respect to DUI sentencing in Pennsylvania. To put things briefly, a first offense tier one DUI would result in lesser penalties than, say, a second or third offense under tier three. It can become very nuanced in terms of what the actual penalties would be per DUI and per tier.
An experienced Pennsylvania DUI defense attorney will help you understand what the potential consequences are, and as importantly, will help you best defend against a DUI case. They should be involved from as early as possible.
