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 curfewIntermediate license holders may not drive between 10 p.m. and 5 a.m. unless going to or from work or school.
  • Passenger limitIntermediate license holders may carry no more than 1 passenger (other than immediate family).
  • Cell phone ruleAll cell phone use banned for drivers under 18 with learner or intermediate license.
  • Supervised practiceYou must complete 50 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 Oklahoma 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 Oklahoma-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.
