- 0.08%
- 0.10%
Explanation: Pennsylvania's adult DUI limit is .08 BAC. It is .02 for drivers under 21 and .04 for commercial drivers.
Pennsylvania DMV is administered by the Pennsylvania Department of Transportation (PennDOT), headquartered in Harrisburg. The official Pennsylvania written knowledge exam has 18 questions, and drivers must answer 15 correctly (83%) to pass. Our practice tests match the exact format, topics, and difficulty of the real Pennsylvania DMV test.
What makes the Pennsylvania DMV test unique?
Pennsylvania has the shortest standard exam in the US at 18 questions, but the 83% pass threshold (only 3 mistakes allowed) makes it surprisingly difficult.
Pennsylvania's "Steer Clear" law requires drivers to move over or slow down for emergency and disabled vehicles with flashing lights.
With only 3 allowed mistakes out of 18, focus on high-accuracy practice rather than speed.
