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 curfewProvisional license holders may not drive between midnight and 5 a.m. unless with a parent or 21+ licensed driver.
- Passenger limitFor the first 5 months provisional license holders may not carry passengers under 18 (other than immediate family).
- Cell phone ruleAll cell phone use banned for drivers under 18.
- Supervised practiceYou must complete 60 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 Maryland 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 Maryland-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.
