Oklahoma DMV Permit Practice Test

The Oklahoma knowledge test is the first checkpoint between you and a learner permit. Every question comes from the Oklahoma Driver's Manual, and Service Oklahoma won't tell you which ones you missed if you fail — you only get the verdict. At 50 questions, Oklahoma's test is one of the longest in the country, so preparation matters more here than in states with 25-question exams.

• ✓
  Under-18 exam50 questions. Pass at 40 correct (80%). Same format and passing score as the adult test.
• ✓
  Adult first-time exam50 questions. Pass at 40 correct (80%). At 50 questions this is roughly twice as long as the national average — budget extra prep time.
• ✓
  Permit fee$42.50 issuance fee when you pass. Each failed written test attempt costs an additional $4.00 — so passing on the first try saves money.
• ✓
  Bring with youProof of identity and Oklahoma residency. Book your appointment at a Service Oklahoma driver license office (the agency formerly called DPS driver licensing).
• ✓
  Under 16? Driver ed is required.If you're 15, you must be enrolled in an approved driver education course before you can test. At 16 and older, driver ed becomes optional — but completing it shortens your path to a full license.
• ✓
  Why Oklahoma is tougher than averageDouble the question count of most states, an 80% passing bar, and a $4 re-test fee each time you fail. The manual covers signs, right-of-way, speed limits, impaired driving, and GDL rules thoroughly — all of it is fair game.

Traffic laws dominate Oklahoma's question bank at 169 of 393 questions — that's 43% of the pool. Road signs (82 questions) and safety scenarios (100 questions) fill out the rest. Together those three categories make up more than 90% of what you'll see. Master them first.

• ✓
  Road signs & signals (~21% of bank)82 questions cover sign shapes, colors, and meanings. Warning signs are yellow; work-zone signs are orange with black markings. A round sign always means railroad crossing ahead. (Q12913, Q12900)
• ✓
  Right-of-way & turningAt a four-way stop, proceed in the order of arrival. When two vehicles arrive simultaneously, the driver on the left yields to the driver on the right. Always yield to pedestrians — even jaywalkers. (Q13049, Q13223, Q12893)
• ✓
  Signal distanceActivate your turn signal at least 100 feet before any turn. Three to four seconds of signal time is the stated minimum — earlier is always safer. (Q12983, Q13054, Q12915)
• ✓
  Railroad crossing stop distanceStop between 15 and 50 feet from the nearest rail when a train is approaching. Trains extend at least 6 feet beyond each rail — staying 15–50 feet back keeps you safe. (Q13277)
• ✓
  Following distance3 seconds minimum under normal conditions. Increase to 4 seconds or more in bad weather, at night, or when following large vehicles that block your sightlines. (Q13224, Q13004)
• ✓
  BAC limit — drivers 21+0.08% is the legal per-se limit. At or above 0.08% you are driving under the influence (DUI) regardless of how you feel. (Q13172, Q13272)
• ✓
  Oklahoma speed limits70 mph maximum on four-lane divided highways and two-lane superhighways; 65 mph on undivided roads. Posted maximums apply only in ideal conditions — adjust for weather and traffic. (Q13268, Q12930)
• ✓
  Reducing BAC — only one method worksTime is the only thing that lowers your blood alcohol concentration. Coffee, exercise, and cold showers cannot sober you up — the test asks this directly. (Q12885, Q12943)

These are the categories that sink more first-time Oklahoma test-takers than any other. If you only have time to drill a few topics, make it these.

• ✓
  Three-car right-of-way at a four-way stopEveryone knows 'first to arrive goes first.' Almost no one handles it correctly when three cars arrive at the same moment. The rule is yield to the driver on your right when arrival is simultaneous. (Q13049, Q13088, Q13223)
• ✓
  School bus rulesStop in both directions when the red lights flash and the stop arm is extended. Do not move until the lights stop flashing, the stop arm retracts, AND the bus begins moving. School buses also must stop at all railroad crossings — be ready to stop behind them. (Q13003, Q13010, Q13199)
• ✓
  Hill parking — downhill (or uphill, no curb)Turn wheels TOWARD the road edge (right) so the car rolls away from traffic if the brakes fail. This applies both downhill and uphill when there is no curb. (Q13117, Q13121, Q13215)
• ✓
  Hill parking — uphill with a curbTurn wheels AWAY from the curb (left). If the vehicle rolls, the curb stops it before it enters traffic. (Q13190, Q13214, Q13216)
• ✓
  Impairment vs. legal limit0.08% is the legal BAC cutoff — NOT the point where impairment begins. Impairment starts at the first drink. The test asks the difference; don't confuse the two. (Q12920, Q13172)
• ✓
  'Always' / 'never' answer optionsUsually wrong — but in Oklahoma's bank there are genuine absolutes. You must ALWAYS yield to pedestrians, even jaywalkers. You must NEVER pass on a railroad crossing or bridge. Look for evidence before dismissing an absolute. (Q12893, Q12944)
• ✓
  Passing a bicycleSlow down and give the cyclist as much space as possible. Bicyclists may have to swerve into traffic to avoid road hazards — never crowd them. When an oncoming car and a cyclist create a squeeze, deal with one hazard at a time. (Q13151, Q13219, Q13152)

Reading alone reliably tops out around 60% on the real test. The students who pass first try use three loops: read once, drill once, listen once. With 50 questions to answer at 80%, Oklahoma leaves less margin for error than most states — that third loop matters.

• ✓
  Loop 1 — read the handbookDownload the Oklahoma Driver's Manual free from the Service Oklahoma website. Read it once end-to-end. Don't memorize — just get familiar. This guide compresses the highest-yield 20% into bullets.
• ✓
  Loop 2 — drill the practice examsTake the free 40-Q exam below cold. Our bank has 393 questions across 9 distinct exams for Oklahoma. Anything under 32/40 on a practice run means you need another pass through the weak categories before you book your appointment.
• ✓
  Loop 3 — listen along on YouTubePlay the Oklahoma Cheat Sheet video the day before your test. Hearing the questions out loud — question then answer — locks them in faster than re-reading.
• ✓
  Sleep beats crammingMemory consolidates overnight. A full sleep before your appointment is worth more than two extra hours of late-night reading.
• ✓
  Study signs visuallyNever study sign descriptions in text only. Look at the actual shape, color, and symbol. The Oklahoma test shows you the sign image — not a text description of it.
• ✓
  Read every option before pickingOklahoma's bank has 3-option (A/B/C) and 4-option (A/B/C/D) questions. Service Oklahoma writes plausible wrong answers — the first option often looks correct until you read all the others and find a more precise one.

Passing the knowledge test gets you a learner permit — not a full license. Oklahoma's graduated driver licensing (GDL) rules are stricter than most states: the 10pm curfew is earlier than the midnight cutoff used elsewhere, and restrictions lift on a timeline that depends on whether you completed driver education.

• ✓
  Permit supervisionWhile on your learner permit, you may only drive between 5:00 a.m. and 10:00 p.m. with a licensed driver at least 21 years old present in the vehicle.
• ✓
  Minimum permit hold180 days (approximately 6 months) before you're eligible for the road test. You cannot fast-track this — the clock doesn't start until the permit is issued.
• ✓
  Supervised driving hours50 total hours of supervised driving required, including at least 10 hours at night, before graduating to an intermediate license.
• ✓
  Intermediate license — night curfewCannot drive alone between 10:00 p.m. and 5:00 a.m. Exceptions: travel to or from school, church, or work activities, or when a licensed adult (21+) is in the front seat.
• ✓
  Intermediate license — passenger restrictionLimited to one non-household passenger while driving alone. Household members may always ride. Any number of passengers is permitted when a licensed adult (21+) is present in the front seat.
• ✓
  Work Zone Safe courseOklahoma requires completion of the 'Work Zone Safe' online course before you receive your intermediate license. This is an Oklahoma-specific requirement not found in most states — don't overlook it.
• ✓
  When restrictions lift — with driver edHold the intermediate license for at least 6 months AND stay free of any traffic convictions for the most recent 180 days. Both clocks must be satisfied; a conviction restarts the 180-day clean-record window. Completing driver education unlocks this faster path (vs. 12 months without).
• ✓
  When restrictions lift — without driver edHold the intermediate license for at least 12 months AND stay free of any traffic convictions for the most recent 12 months. Both clocks run together; a conviction resets the clean-record window. Without driver education the wait is twice as long.
