Oklahoma Road Signs: 80 mph Turnpikes & 1-Year School Bus Revocation

What is the speed limit on Oklahoma turnpikes? What is the penalty for passing a school bus in Oklahoma? Are Oklahoma work zone and school zone fines doubled? Oklahoma turnpike limits reach 80 mph. Failing to stop for a school bus with red lights flashing means mandatory 1-year license revocation. first offense. Fines double for violating an active posted school-zone speed limit; construction-zone speeding fines double when workers or equipment are present. Church buses carry the same stop requirements as school buses. Service Oklahoma at oklahoma.gov/service administers all driver license functions.

1. Oklahoma Written Test, 80 mph Turnpikes and the Bernardo-Mills Move Over Law

Oklahoma roads cross I-40s transcontinental corridor through Oklahoma City, the I-44 Turner Turnpike between OKC and Tulsa, the US-69 corridor through the Ouachita foothills, and the open plains of the Panhandle. Service Oklahoma at oklahoma.gov/service administers driver license services. How many questions are on the Oklahoma written test? The written test has 20 questions covering Oklahoma traffic laws, road rules, road signs, and safe driving practices; 15 correct answers are required to pass. Skills tests can be taken from a designated private examiner (for a fee) or free from Service Oklahoma. List of approved examiners at oklahoma.gov/service/all-pages/drive-schools.

2. Oklahoma Sign Shapes: What the Written Test Covers From Turnpike Speed Signs to School Zone Markers

Oklahoma sign environment includes turnpike toll and speed signs; statewide maximums include 80 mph on turnpikes, 75 mph on controlled-access highways, and 55 mph on county roads unless otherwise posted. On the state flat open plains where a sign is visible for miles, and on the winding Ouachita Mountain routes, shape and color identify a sign before text is readable. Know every row in this table before your Service Oklahoma written test.

Shape	Diagram	Meaning	Example Sign
Octagon (8-sided)		STOP. come to a complete stop, wheels fully stopped, check all directions, then proceed when clear
Triangle (inverted)		Yield slow down, check traffic; if clear proceed, if not stop and wait until safe to go
Diamond		Hazard ahead; slow down, stay alert, and be ready to stop or steer
Rectangle (vertical)		Legal requirement; obey this sign or face fines and points on your record
Rectangle (horizontal)		Informational sign; read it and use it to navigate or plan your route
Pentagon (5-sided)		School zone ahead; reduce speed and watch for children crossing
Round (circle)		Railroad crossing ahead; slow down, look both ways, and prepare to stop
Pennant		No passing zone; do not attempt to overtake any vehicle ahead
Orange (any shape)		Construction or work zone ahead; slow down, stay alert, and obey all posted signs
Blue (any shape)		Motorist services nearby; exit if you need fuel, food, or medical care
Brown (any shape)		Park or scenic area ahead; follow directional signs to reach it

3. Oklahoma Regulatory Signs: 1-Year Mandatory Revocation for Bus Violations and the Mandatory Point System

Regulatory signs carry legal force under Oklahoma Statutes (O.S.). Key OK penalties: failure to stop for a school bus with red loading/unloading lights flashing = mandatory 1-year license revocation.

6. Oklahoma Traffic Signals: Church Bus Red Lights and What the Written Test Covers

Flashing red = stop sign. Flashing yellow = caution: slow down, look in both directions, and proceed carefully. What does a flashing yellow arrow mean in Oklahoma? It permits a left turn after yielding to oncoming traffic and pedestrians; a flashing red arrow requires a stop and waiting for a green signal before turning. Oklahoma includes church buses alongside school buses. red flashing lights on a church bus carrying children carry the same stop requirement. The Bernardo-Mills Move Over Law (47 O.S. Section 11-314) also requires drivers to move over or slow down for stationary vehicles with flashing lights on the roadside.

Oklahoma lane-control signals: a red X means do not use the lane; a yellow X means clear the lane; a flashing yellow X permits a left turn; and a green downward arrow means the lane is open for traffic.

Standard Traffic Lights

Steady Red

Flashing Yellow

Slow down, check for hazards, and proceed with caution

Flashing Red Beacon

Treat the overhead beacon as a stop sign

Pedestrian Signals

WALK / White Walking Figure & DONT WALK / Orange Hand

White figure = cross now; orange hand = do not start crossing

7. Oklahoma Pavement Markings: Lane Lines, 50-Foot Railroad No-Parking Zone and Turnpike Lane Rules

Yellow lines separate opposing traffic. White lines separate same-direction traffic. The Oklahoma written test covers lane lines, road arrows, curb markings, and pavement symbols. including the no-parking zone within 50 feet of the nearest rail of a railroad crossing, and turnpike lane markings used on Oklahoma extensive toll road network.

Line Colors

Yellow lines

Separate opposing traffic; never cross a solid yellow line to pass

White lines

Mark your lane boundaries; stay within the white lines

Line Types

Broken yellow line (Single)

You may pass on your side if it is safe and clear ahead

• You must obey flaggers directing traffic in Oklahoma construction zones.
• Construction or maintenance zone speeding fines double when workers or equipment are present.
• Oklahoma’s Basic Speed Rule carries a maximum penalty of up to $654 and 30 days in jail.
• Never drive through or around a lane closure barrier. follow channelizing devices and posted detour signs.

Key test point: Orange always means construction or work zone. If you see orange, reduce speed and increase following distance immediately.

9. Oklahoma Railroad Crossings: Stop Within 50 Feet But Not Less Than 15 Feet: By Oklahoma Statute

Oklahoma law (O.S.) specifically states that any driver approaching a railroad grade crossing must stop within 50 feet but not less than 15 feet from the nearest rail when: a signal device warns of an approaching train; a crossing gate is lowered; a flagperson signals; or a train is approaching. Do not proceed until it is safe to do so.

What does a No Train Horn sign mean in Oklahoma? It identifies a railroad Quiet Zone where trains normally do not sound their horns. Train engineers may still sound the horn in emergencies or when needed for safety.

Stop Line

Stop here completely when required before proceeding

RR Crossbuck Sign (X-shaped)

• No parking within 50 feet of the nearest rail of a railroad crossing.
• Never stop on the tracks. wait before the crossing until there is room on the far side.

Key test point: Oklahoma railroad stop zone = within 50 feet but not less than 15 feet from the nearest rail when a stop is required.

10. Oklahoma School Bus Laws: 1-Year Mandatory Revocation, Church Bus Rules and When You Do not Have to Stop

Pentagon-shaped school zone signs mark Oklahoma school zones. Outside municipalities, the school zone speed is 25 mph in a properly marked zone. cities and towns set their own limits. When a school bus or church bus displays flashing red lights and/or a red STOP sign, you must stop and remain stopped until the bus moves, the driver signals, or the red lights go off. First-time failure to stop = mandatory 1-year license revocation.

School Zone

School ahead; reduce speed and watch for children

School Speed Limit

Obey the reduced speed limit posted in school zones

Speed Limit Lights Flashing

Obey the posted speed limit only when the lights are flashing

School Crossing Ahead

School crosswalk ahead; yield to crossing guard and children

• Oklahoma school zone speed outside municipalities: 25 mph in a properly marked zone. Cities and towns set their own limits. watch carefully and obey all posted signs in business, residential, and school zones.
• When a school bus or church bus shows flashing red lights and/or a red STOP sign, you must stop and remain stopped until: the bus starts moving; the driver signals you to proceed; or the red flashing lights go off.
• Mandatory 1-year license revocation for failing to stop for a school bus with red loading/unloading lights flashing. first offense.
• You do not have to stop when: the bus is on a different roadway; the bus is in a loading zone by a controlled-access highway where pedestrians cannot cross; or you are approaching on a divided highway.
• When a posted reduced school-zone speed limit is in effect, exceeding that limit results in double the appropriate fine.

Key test point: The pentagon shape is used exclusively for school signs. No other sign category uses this shape. making it one of the easiest shapes to identify on the exam.

11. Oklahoma Pedestrian and Bike Signs: Crosswalk Right-of-Way and the 3-Foot Bicycle Passing Rule

Pedestrians have right-of-way at all crosswalks in Oklahoma. marked or unmarked. When overtaking and passing a bicycle, Oklahoma law requires leaving at least 3 feet of clearance until the motor vehicle is safely past. Fluorescent yellow-green may be used for pedestrian, bicycle, and school warning signs.

Pedestrian Crossing Sign

Crosswalk ahead; yield to any pedestrian in or entering the crosswalk

Bicycle Crossing Sign

Cyclists cross here; slow down and yield before proceeding

No Bicycles

Cyclists must not enter; use an alternate route

No Pedestrian Crossing

Pedestrians must not cross here; use the nearest crosswalk

• Pedestrians always have right-of-way in Oklahoma crosswalks. marked or unmarked. Be especially alert in school zones and high-traffic pedestrian areas.
• Oklahoma law requires at least 3 feet of clearance when overtaking and passing a bicycle, and maintaining that clearance until safely past.
• Bernardo-Mills Move Over Law (47 O.S. Section 11-314): when approaching any stationary vehicle with flashing lights on the roadside, move over a lane if safe, or slow down and use caution.
• Fluorescent yellow-green is used for both school and pedestrian/bike signs. the shape distinguishes between them.

Key test point: Drivers must yield the right-of-way to pedestrians in marked or unmarked crosswalks as required by Oklahoma law.

12. How to Pass Oklahoma Written Test: 80 mph Turnpikes, Mandatory Revocation and the Church Bus Rule

• Oklahoma written test: 20 questions. Service Oklahoma says the exam covers Oklahoma traffic laws, road rules, road signs, and safe driving practices. You need 15 correct answers to pass.
• Oklahoma speed limits by road type. Turnpikes: 80 mph. Controlled-access highways: 75 mph. Undivided state highways: 65 mph. County roads: 55 mph. State parks/wildlife refuges: 35 mph. School zones outside municipalities: 25 mph. Controlled-access minimum: usually 40 mph.
• Mandatory 1-year revocation for school bus violations. No discretion. the law mandates revocation for failing to stop for a school bus with red lights flashing. Church buses carry the same requirement.
• School-zone and construction-zone fine triggers differ. School-zone speeding fines double when the posted reduced limit is in effect; construction or maintenance speeding fines double when workers or equipment are present.
• Railroad: within 50 feet but not less than 15 feet from the nearest rail. Stop in this range when a railroad signal, lowered gate, flagperson, or approaching train requires it. A train at 55 mph needs a mile or more to stop.
• Bernardo-Mills Move Over Law (47 O.S. Section 11-314). Move over a lane when safe or slow down and proceed with caution for stationary roadside vehicles displaying flashing lights.
• 3 feet for cyclists. Oklahoma statute. Required clearance when overtaking a bicycle. Maintain until safely past.
• Church buses same as school buses. Oklahoma treats church buses carrying children identically to school buses for stop purposes.
• Flashing signals. Flashing red = full stop. Flashing yellow = proceed with caution. A flashing yellow arrow allows a left turn after yielding.
• Visit oklahoma.gov/service. Service Oklahoma handles all driver license functions. List of approved designated examiners at oklahoma.gov/service/all-pages/drive-schools.
