What Makes Underage DUI Different
In Pennsylvania, drivers under 21 face very different DUI laws than drivers who are 21+. A 21+ driver has a certain amount of leeway in driving with alcohol in their system—as long as their blood alcohol concentration (BAC) is less than .08%, and they aren’t showing signs of impairment, they usually cannot be convicted of DUI. But Pennsylvania has adopted a “Zero Tolerance” rule for drivers who are under 21 years of age. These younger drivers face much higher standards than adults do.
The main areas that are different for underage drivers are:
- The rules for breath tests
- The “legal limit” for having alcohol in their system
- The penalties they face
We’ll cover each of these areas in detail below.
How are DUI breath test rules different for drivers under 21?
The first step of most DUI investigations is to ask the driver to take a breath test. Officers can do this during a traffic stop with a portable device.
What is the legal limit for drivers under 21?
For adults, the “legal limit” is .08% BAC. The legal limit for drivers under 21 is .02%. Because of the state’s Zero Tolerance law, it is illegal for you to drive with any measurable amount of alcohol in your system. If you take the breath test and blow even a .01%—the smallest amount of alcohol it can record—you are in violation of the law. Just because there is alcohol in your system doesn’t mean you’ll be convicted of a full DUI.
