The four rules that show up on the test
Most state permit exams include at least one question about each of the four rules below. They're also the rules police are most likely to enforce against new drivers in your first year.
- Night-driving curfewJunior license holders may not drive between 11 p.m. and 5 a.m. unless going to or from work, school, or volunteer fire/rescue.
- Passenger limitJunior license holders may carry no more than 1 non-family passenger under 18 for the first 6 months; up to 3 thereafter.
- Cell phone ruleTexting while driving banned for all drivers.
- Supervised practiceYou must complete 65 hours of supervised driving (10 at night) with a licensed driver age 21 or older before taking the road test.
Why GDL laws exist
Every U.S. state has some form of Graduated Driver License (GDL) program because crash data is unambiguous: the first six months of independent driving are the most dangerous time in a driver's life. The Insurance Institute for Highway Safety (IIHS) estimates that strong GDL laws — meaning a learner stage of at least six months, a night curfew, and a passenger limit — have cut fatal teen-driver crashes by roughly 30% in states that adopted them.
The Pennsylvania permit test will ask you to recognize these rules even before you start driving on your own. Memorize the night curfew time, the supervisor age, and the passenger limit; those are the three details state DMV exams ask about most often.
How the practice questions cover GDL
About 4 to 6 of the 25-50 questions on a typical state permit exam test GDL details directly. We've sprinkled Pennsylvania-specific GDL questions throughout the Traffic Laws and Safe Driving Practices drills.
Official sources
Always verify these numbers with an official source before testing — small details (especially night-curfew start times and passenger exemptions) get amended every few years.
