The basics, in plain English, from the Oklahoma Driver Manual.
With an approved driver education course (school, commercial or parent-taught) you can get a learner permit at 15; without one, at 16. (Oklahoma Driver Manual, p. 6)
Service Oklahoma's written test has 20 questions and you need 15 right. You can take it online with a webcam (60 minutes, two tries) or at a Service Oklahoma location. (Service Oklahoma: Written Knowledge Test)
Teens hold the learner permit for at least 180 days, with a licensed driver 21 or older beside them, before the drive test for an intermediate license. (Oklahoma Driver Manual, p. 6)
The graduated license allows driving from 5 a.m. to 10 p.m. (except for school, church or work, or with a licensed driver 21+) and one passenger unless all live in your home. (Oklahoma Driver Manual, p. 14)
Oklahoma teaches three seconds behind the vehicle ahead, or a car length for every 10 mph, and four seconds in bad weather. (Oklahoma Driver Manual, p. 44)
For any stopped vehicle with flashing lights at the roadside, move to a lane that isn't next to it if you safely can, or slow down and drive carefully. (Oklahoma Driver Manual, p. 30)
Yes, on a desktop or laptop with a webcam and microphone (not a phone or touch screen), in English, with 60 minutes to finish. Under 18, a parent or guardian must be there to verify your identity. You get two online tries; after that you test in person. (Service Oklahoma: Written Knowledge Test)
15, if you are taking or have passed an approved driver education course (public school, commercial school or parent-taught); 16 without driver education. (Oklahoma Driver Manual, p. 6)
You may drive from 5 a.m. to 10 p.m., or at other times for school, church or work or with a licensed driver 21 or older. You may carry one passenger, unless everyone lives in your home or a licensed driver 21+ sits in the front seat. (Oklahoma Driver Manual, p. 14)
No. Texting while driving has been illegal since 2015, and drivers with a learner permit or intermediate license can lose their license for using a hand-held device except in a life-threatening emergency. (Oklahoma Driver Manual, p. 61)
