Do you know how many drinks you can have before you're in danger of getting charged with driving under the influence? 

This year in our area, there have been numerous car accidents caused by drunken driving, and several other people pulled over while driving drunk. This St. Patrick's Day weekend, Patch wants you to know when enough is enough.

When police pull drivers over for suspected drunken driving, officers ask them to perform field sobriety tests and to take a breath test to measure Blood Alcohol Content.

A BAC test measures the percentage of alcohol present in a person's bloodstream. Pennsylvania's legal limit is 0.08 percent.

According to the Virginia Tech Alcohol Abuse Prevention website, every 40 minutes, 0.01 percent of alcohol leaves your system.
