Oklahoma DMV Permit Practice Test

The Oklahoma knowledge test is the first checkpoint between you and a learner permit. It has 20 questions, so preparation matters — study the Oklahoma Driver's Manual before you sit down.

• ✓
  Under-18 exam20 questions. Pass at 15 correct (75%). Same format and passing score as the adult test.
• ✓
  Adult first-time exam20 questions. Pass at 15 correct (75%). 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 (Service Oklahoma took over driver licensing from the Department of Public Safety).
• ✓
  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 preparation matters20 questions, a 75% passing bar, and a $4 fee each time you fail. The manual covers signs, right-of-way, speed limits, impaired driving, and GDL rules thoroughly — study all of it.

Master the traffic laws first. Road signs and safety scenarios matter too.

• ✓
  Road signs & signalsKnow 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.
• ✓
  Right-of-way & turningVehicles at a four-way stop go in the order they arrived. If two arrive together, the left-hand driver gives way to the one on the right. Always give way to pedestrians in a crosswalk, marked or unmarked, and never rush or scare a pedestrian.
• ✓
  Signal distanceActivate your turn signal at least 100 feet before any turn — earlier is always safer.
• ✓
  Railroad crossing stop distanceWith a train approaching, your stopping spot should be at least 15 feet and no more than 50 feet short of the closest rail. Since a train overhangs each rail by at least 3 feet, staying 15–50 feet back keeps you safe.
• ✓
  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.
• ✓
  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.
• ✓
  Oklahoma speed limitsUnless otherwise posted: 75 mph on controlled-access highways, 80 mph on turnpikes, 65 mph on undivided state highways and 55 mph on county roads. Cities and towns set their own limits, so obey the posted signs. Posted maximums apply only in ideal conditions — adjust for weather and traffic.
• ✓
  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.

These topics are easy to mix up. If you only have time to drill a few topics, make it these.

• ✓
  Three-car right-of-way at a four-way stop'First to arrive goes first' is the easy part. Three cars arriving at the same moment is trickier. The rule is yield to the driver on your right when arrival is simultaneous.
• ✓
  School bus rulesStop when the red lights flash and the stop arm is extended — traffic in both directions must stop, except oncoming traffic on a divided highway. Stay stopped until the bus starts moving, the driver motions you to proceed, or the red lights go off and/or the stop arm is pulled back. School buses also must stop at all railroad crossings — be ready to stop behind them.
• ✓
  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.
• ✓
  Hill parking — uphill with a curbTurn wheels AWAY from the curb (left). If the vehicle rolls, the curb stops it before it enters traffic.
• ✓
  Impairment vs. legal limit0.08% is the legal BAC cutoff — NOT the point where impairment begins. Impairment starts at the first drink. Don't confuse the two.
• ✓
  'Always' and 'never' rulesSome Oklahoma rules are genuine absolutes. You must ALWAYS yield to pedestrians in a crosswalk, marked or unmarked. You must NEVER pass at a railroad crossing, and never pass where a bridge, hill or curve blocks your view. Don't dismiss an absolute without checking it against the handbook.
• ✓
  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.

Reading the handbook once may not be enough. Try three loops: read once, drill once, listen once. With only 20 questions to answer at 75%, every miss counts — 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 pulls the key points into bullets.
• ✓
  Loop 2 — drill the practice examsTake the free 40-Q exam below cold. 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. It makes a useful last review.
• ✓
  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.
• ✓
  Read every option before pickingRead every option before you answer. A plausible-looking option may not be the most precise one, so compare them all before you pick.

Passing the knowledge test gets you a learner permit — not a full license. Oklahoma's graduated driver licensing (GDL) rules include a 10pm curfew, 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 seated beside you.
• ✓
  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 restrictionWithout a licensed adult (21+) in the front seat, you may carry only one passenger — unless every passenger lives in your household. With that adult beside you, any number of passengers is permitted.
• ✓
  Work Zone Safe courseOklahoma requires completion of the 'Work Zone Safe' online course before you receive your intermediate license. This is an Oklahoma requirement — 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.
