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 in both school and construction zones 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. The written test questions come directly from this manual. covering Oklahoma traffic laws, safe driving practices, and drug and alcohol information. 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 (80 mph), controlled-access highway markers (75 mph), and county road signs (55 mph). 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. always and only
Triangle (inverted)		Yield to other traffic
Diamond		Warning - hazard ahead
Rectangle (vertical)		Regulatory - rules of the road
Rectangle (horizontal)		Guide or informational
Pentagon (5-sided)		School zone or crossing - exclusively
Round (circle)		Railroad crossing advance warning - exclusively
Pennant		No passing zone - exclusively

Crossing phase is ending. Pedestrians who have started may finish; others should not begin.

Key test point: Flashing red = stop sign. Flashing yellow = yield. Church bus red lights = same stop requirement as school buses. Move Over Law applies to all stationary flashing-light vehicles. All tested on the Oklahoma written exam.

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.

• Excessive speeding can result in a fine of up to $654 and 30 days in jail in Oklahoma.
• 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.

• 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. This exact language is in Oklahoma statute and is tested on the written exam.

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. be alert for children, reduce speed

School Speed Limit

Oklahoma school zones outside municipalities: 25 mph; cities set own limits; failure to stop for school bus red lights = mandatory 1-year revocation

• Fines double in school zones when workers or equipment are present.

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: 3-Foot Minimum and the Bernardo-Mills Move Over Law for Cyclists Too

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. The Bernardo-Mills Move Over Law also applies when passing stationary cyclists or roadside pedestrians. move over or slow down. Both sign types use fluorescent yellow-green and are tested on the Oklahoma written exam.

Pedestrian Crossing Sign

A marked crosswalk is ahead. watch for pedestrians crossing

Bicycle Crossing Sign

Cyclists frequently cross here. reduce speed and yield to bikes

No Bicycles

Bicycles are prohibited on this road or path

No Pedestrian Crossing

Pedestrians must not cross here

• 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: Pedestrians always have right-of-way at crosswalks. marked or unmarked. This rule appears on virtually every state DMV exam.

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

• Written test questions come directly from this manual. Study the Oklahoma Driver Manual. every question covers Oklahoma traffic laws, safe driving, and drug and alcohol information. Skills test can be taken free from Service Oklahoma or for a fee from a designated private examiner.

• 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.
• Fines double in school AND construction zones. same rule. Oklahoma uses one rule for both: fines double when workers or equipment are present in either zone type.
• Railroad: 50 feet max, 15 feet min from nearest rail. This exact language is in Oklahoma statute (O.S.) and appears on the written test. A train at 55 mph needs over a mile to stop.
• Bernardo-Mills Move Over Law (47 O.S. Section 11-314). Move over a lane or slow down for any stationary vehicle with flashing lights on the roadside. not just emergency vehicles. This is tested.
