In Pennsylvania, there is no one rule when it comes to sentencing. It depends on the driver’s BAC, how many former arrests and how much in fines the driver has previously paid. If the driver caused any damage to life or property, that also will increase the sentencing, including fines. If the driver was previously jailed, it’s likely to be increased for any additional charges. Fines are increased for each offense. Suspension of driving privileges will also be a factor.
A first time offender with no injuries or property damage would likely get a light sentence depending on his/her BAC.
I have arrested drunk drivers with 3 and 4 previous DUI’s and was driving without a license. A severe case such as this would net the driver at least 6 months in County, a $5000+ fine and 1-2 years license suspension. They would have to report to driver’s education classes and pay all their fines to get their license back. I have seen licenses revoked for life, if any personal injury was caused by the drunk driver.
