Pennsylvania DUI Laws

One of the most common criminal charges in Pennsylvania (as in other states) is driving under the influence (DUI) of alcohol or other drugs, since both driving and social drinking are ubiquitous. But it's also one of the most strictly enforced criminal offenses, with penalties including prison time and fines in the thousands of dollars. A DUI conviction also affects one's auto insurance rates, eligibility for certain jobs, and other aspects of life beyond the courtroom.

If it is your first DUI offense, you will be put on probation for up to six months, pay a $300 fine, and be ordered to complete traffic safety school. But penalties get much more severe from there. For instance, you could be sentenced to as much as two years in prison if it is your third or successive offense. A conviction for a DUI with a blood alcohol concentration (BAC) of 0.16 percent or higher, meanwhile, will get you at least three days -- and up to six months -- in prison if you have no prior offenses.
