Wyoming Road Signs: WYDOT Exam, 80 mph Interstates & Bike Law

What is the speed limit on Wyoming interstates? How many times can you take the Wyoming written test in one day? What does a flashing yellow light mean in Wyoming? What does Wyoming law say about passing a cyclist when you do not have a clear lane? The Wyoming DOT (WYDOT) Driver Services at dot.state.wy.us administers exams at statewide stations. Interstate limits reach 80 mph where posted. WYDOT allows the same written test to be taken twice in one day. A flashing yellow signal means proceed with caution. When there is not adequate space to pass a bicyclist, the Wyoming Driver License Manual says to slow to the cyclist's speed and follow until there is room to pass. A police officer's directions outweigh traffic lights or signs.

1. Wyoming 80 mph Interstates, Written-Test Rules and Why a Police Officer Overrules Every Traffic Sign

Wyoming roads stretch from Cheyenne I-25/I-80 interchange across the high-altitude US-287 Wind River Basin, through Casper oil country corridor on I-25, and up to the Yellowstone and Grand Teton approach routes on US-26 and US-191. WYDOT Driver Services at dot.state.wy.us (5300 Bishop Blvd, Cheyenne WY 82009) runs driver license exam stations statewide. The Wyoming written test covers traffic signs by shape, color or symbol, signals and pavement markings, and questions on traffic laws, safety rules, crash prevention and vehicle equipment. The same written test may be taken twice in one day. Skills test can be waived with an approved driver education certificate. A police officer's directions always outweigh any traffic light or sign in Wyoming.

2. Wyoming Sign Shapes: Construction Signs Are Black on Orange and What the WYDOT Knowledge Test Covers

Wyoming manual is explicit: construction signs have black lettering on an orange background. On the state open plains where a sign may be visible for miles before you reach it, shape and color identify the message at speed. Know every row in this table before your WYDOT exam station visit.

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. Wyoming Regulatory Signs: Police Override Rule, Move-Over Law at 20 mph and Required Stops Listed in Wyoming Statute

Regulatory signs carry full legal force in Wyoming. A police officer's directions outweigh traffic lights or signs, always follow the officer. Wyoming's Move Over law requires moving to the lane farthest from an authorized emergency, municipal, public utility, highway construction or maintenance vehicle using required visual signals when a same-direction lane is available. On a two-lane road posted at 45 mph or higher, reduce speed to 20 mph below the posted limit when the law applies. White rectangular signs, prohibitory signs, and lane-control signs are covered in the WYDOT Driver License Manual.

4. Wyoming Warning Signs: Wind River Canyon Grades, Yellowstone Approach Curves, Wildlife Crossings and Blind Intersection Approaches

Diamond-shaped yellow warning signs flag hazards before you reach them. on Wyoming roads that means steep grade warnings on Wind River Canyon and Teton Pass approaches, curve warnings on US-14 through the Bighorn Mountains, wildlife crossing signs for pronghorn, elk, and bison on open range highways, and intersection warnings where reduced sight distance requires extra caution. Wyoming separately sets a 15 mph maximum for a blind intersection when the statutory sight-distance condition applies. Black on orange marks construction zones. Wyoming plains and mountain highways both demand acute awareness of warning signs.

You are on this interstate highway; note the number for navigation

US Route Marker

You are on this US highway; note the number for navigation

6. Wyoming Traffic Signals: Police Override Rule and What the WYDOT Knowledge Test Covers

Flashing red = stop sign. Flashing yellow = proceed with caution. A flashing yellow arrow allows the indicated turn only after yielding to oncoming traffic and pedestrians, then proceeding with caution when clear. Wyoming knowledge test covers traffic signals and pavement markings. Wyoming explicitly states that a police officer's directions outweigh traffic lights or signs, always obey the officer, not the signal. Flashing red lights or crossing gates at railroad crossings are required stops.

Standard Traffic Lights

Steady Red

Stop at the stop line, crosswalk, or before entering the intersection; after stopping, right on red and a one-way-to-one-way left on red are allowed unless a sign prohibits the turn, after yielding

Steady Yellow

Slow down and prepare to stop; do not speed up to beat the light

Steady Green

Proceed through the intersection; yield to pedestrians and cross traffic

Green Arrow (left)

Proceed only in the arrow direction; yield to pedestrians

Steady Yellow Arrow

The related green movement is ending or a red signal will appear immediately afterward

Steady Red Arrow

Stop and do not make the arrow movement unless a Wyoming red-signal turn exception applies; yield before turning

Circular Green (no arrow)

Proceed straight or turn right or left unless a sign prohibits the turn; yield to lawful traffic and pedestrians

Opposing Traffic Extended Green

Oncoming traffic still has green; wait and do not turn left yet

Flashing Signals

Flashing Red

Treat as a stop sign; stop fully, then proceed when safe and clear

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

Flashing Orange Hand + Countdown

Crossing phase ending; finish if started, do not begin

Key test point: Flashing red = stop sign. Flashing yellow = proceed with caution. A flashing yellow arrow permits the indicated turn only after yielding to oncoming traffic and pedestrians. A police officer's directions outweigh any traffic signal.

7. Wyoming Pavement Markings: RXR Stop Line Before Railroad Tracks and Open Range Road Edge Lines

Yellow center lines separate opposing traffic, while white lane lines separate traffic moving in the same direction. Solid yellow and white lines are also used as roadway edge lines. The WYDOT knowledge test covers lane lines, road arrows, curb markings, and pavement symbols, including RXR pavement markings and stop lines on railroad crossing approaches.

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

Solid yellow + broken yellow

Pass only from the broken-line side when it is safe; do not pass from the solid side

Double solid yellow lines

Passing is not allowed in either direction; the lines may be crossed to make a left turn into or from an alley, private road, or driveway

Broken white line

You may change lanes if it is safe; always check mirrors and signal first

Solid white line

When separating same-direction lanes, crossing is discouraged because lane changing is hazardous; a solid white line also marks the right roadway edge

Double solid white lines

Do not change lanes here; stay in your current lane

Center Turn Lane

For left turns only; signal, enter the lane, and turn; do not use it to travel

Center Turning Lane (sign)

For left turns only; signal, enter, and turn; do not drive through it

Pavement Symbols & Special Markings

Arrows in lane

You must follow the arrow direction from this lane

Stop line (wide white bar)

Stop completely behind this line; do not roll past it

Stop Here on Red

Stop at this painted line; do not inch forward past it

Crosswalk lines

Pedestrian crossing zone; obey signals and yield as required by Wyoming crosswalk law

Broken white line (pavement)

You may change lanes if it is safe; check mirrors and signal first

Solid white line (pavement)

When separating same-direction lanes, crossing is discouraged because lane changing is hazardous; a solid white line also marks the right roadway edge

Double solid white lines (pavement)

Do not change lanes here; stay in your current lane

Railroad crossing markings (X + RR)

Tracks ahead; slow down, look both ways, and be ready to stop

Diagonal yellow lines (gore area)

Do not enter or drive through this area; it is off-limits to traffic

Bicycle lane marking

Reserved for cyclists only; do not drive or park in this lane

HOV / Carpool lane diamond

Use this lane only if you have the required number of occupants

Wyoming curb markings: WYDOT uses yellow curb markings to show parking restrictions and recommends parking-restriction signs with curb markings. Follow posted signs and local restrictions rather than assuming a statewide red- or white-curb meaning.

Key test point: Yellow center lines separate opposing traffic and white lane lines separate same-direction traffic; solid yellow and white lines can also be used as edge lines. Broken lines may be crossed when safe. Double solid white lines prohibit lane changes. At railroad crossings, stay behind the stop line when a stop is required.

8. Wyoming Work Zone Signs: Slow Down for Workers Even When No Activity Is Visible: and Never Cut In Front of Trucks

Wyoming construction signs have black lettering on an orange background. Drive slowly through work zones and stay alert for workers or equipment entering the traffic stream. Extra care is required even when there is no apparent work activity in the immediate vicinity. A specific Wyoming warning: never pass a heavy vehicle at high speed and then cut back in front of it near a work zone. the truck driver may not have enough braking distance to avoid a rear-end crash.

Road Work Ahead

Construction zone begins ahead; reduce speed and stay alert

Flagger Ahead

A person is directing traffic; obey their signals

Workers Ahead

Road workers are present; slow down and be ready to stop

Active Work Zone

You are in an active work zone; drive with extra caution

End of Active Work Zone

Work zone ends; resume normal speed and check posted limit

Lane Closed Ahead

A travel lane ends ahead; merge early

Road Closed

Road is completely closed; follow detour signs

Orange barrels / cones

Active work zone boundaries; stay within marked lanes

Channelizing devices (barricades)

Follow the barricades; do not drive through or around them

• You must obey flaggers at or near railroad crossings and construction sites in Wyoming.
• Extra care must be maintained through construction work zones even when no apparent activity is visible in the immediate vicinity.
• Never cut in front of a heavy truck after passing it at high speed near a work zone. the truck may not have enough braking distance to stop before rear-ending your vehicle.
• Wyoming Move Over law: when the law applies, move to the lane farthest from the stopped or slow-moving authorized vehicle using required visual signals when a same-direction lane is available. On a two-lane road posted at 45 mph or higher, reduce speed to 20 mph below the posted limit.

Key test point: Orange warning signs indicate construction or maintenance/work-zone conditions. Reduce speed as required, follow temporary traffic controls, and obey flaggers.

9. Wyoming Railroad Crossings: RXR Pavement Markings Lead to the Stop Line: Stay Behind It While the Train Passes

Wyoming railroad crossings use RXR pavement markings on the paved approach, followed by a stop line closer to the tracks. When waiting for a train, stay behind the stop line. Wyoming law requires stopping for flashing red lights or crossing gates at railroad crossings. A flag person at or near railroad crossings must be obeyed.

Stop Line

Stop here completely when required before proceeding

RR Crossbuck Sign (X-shaped)

Located at the crossing; yield to trains

Railroad Crossing (at crossing)

You are at the crossing; stop if lights flash or gate lowers

Crossing Gates

Lower when a train is coming; never drive around a lowered gate

Pavement markings (X + RR)

Tracks ahead marked on pavement; slow down and prepare to stop

Flashing Red Lights

A train is approaching; stop and wait until fully clear

• RXR pavement markings on the road approach warn that a railroad crossing is ahead. slow down and prepare to stop.
• Stay behind the stop line while waiting for a train to pass. do not pull forward into the crossing area.
• Wyoming law requires stopping for flashing red lights or crossing gates at railroad crossings. A flag person at or near a crossing must also be obeyed.
• Never stop on the tracks. Do not attempt to cross until you can clear the crossing completely and safely.
• The blue Emergency Notification Sign (ENS) provides the railroad emergency phone number and crossing-identification information for reporting a stalled vehicle, blocked track, or malfunctioning warning device.

Key test point: RXR pavement markings warn that tracks are ahead. Stay behind the stop line when a stop is required. Flashing red lights or crossing gates require a stop, and the blue ENS sign identifies how to contact the railroad in an emergency.

10. Wyoming School Zone Speed (20 mph), Blind Intersections (15 mph) and School Bus Rules for Divided vs Undivided Roads

Pentagon-shaped signs mark Wyoming school zones. The school-zone speed limit is 20 mph when the reduced speed is designated by official traffic-control devices and appropriate signs. Wyoming separately sets a 15 mph maximum at a blind intersection when the statutory sight-distance condition applies. When meeting or overtaking a stopped school bus with flashing red lights, Wyoming requires stopping from either direction unless a statutory divided-roadway or controlled-access exception applies.

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

• Wyoming school-zone speed is 20 mph where official traffic-control devices and appropriate signs give notice of the reduced speed. The separate blind-intersection maximum is 15 mph when the statutory sight-distance condition applies.
• When meeting or overtaking a stopped school bus with flashing red lights from either direction, you must stop. The driver shall not proceed until the bus resumes motion or the red lights are no longer activated.
• Exception: You may pass if there is a physical barrier or separate roadways between your vehicle and the school bus. use extreme caution and watch for pedestrians.
• On a two or four-lane undivided highway, vehicles in both directions must stop. On a divided roadway, only same-side vehicles must stop.

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. Wyoming Pedestrian and Bike Signs: If You Do not Have a Clear Lane, Follow the Cyclist: Do not Squeeze Past

When traffic-control signals are not in place or are not operating, Wyoming drivers must yield to a pedestrian within or entering a crosswalk by slowing or stopping if necessary. Drivers must also yield to a blind pedestrian carrying a white cane or accompanied by a guide dog. Wyoming bicycle passing rule is specific: when space allows, maintain at least 3 feet of separation. If there is not adequate space to pass, slow to the cyclist's speed and follow until there is room.

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

• When traffic-control signals are not in place or are not operating, a driver must yield by slowing or stopping if necessary to a pedestrian within or entering a crosswalk. Drivers must yield to blind pedestrians carrying a white cane or using a guide dog.
• When space allows, maintain at least 3 feet of separation when passing a bicyclist.
• If you do not have a clear and empty lane, do not attempt to pass, slow to the cyclists speed and follow until you have enough room.
• Avoid prolonged driving next to a bicyclist when sharing a single lane. When passing, reduce your speed to reduce crash risk.
• Bicyclists have the right to access all public roads in Wyoming. give them the same courtesy you would another vehicle.
• Fluorescent yellow-green is used for both school and pedestrian/bike signs. the shape distinguishes between them.

Key test point: When signals are absent or not operating, yield by slowing or stopping if necessary to a pedestrian within or entering a Wyoming crosswalk. A pedestrian may not suddenly leave the curb and enter the path of a vehicle that is too close to yield safely.

12. How to Pass Wyoming WYDOT Knowledge Test: Signs, Signals, 80 mph Routes and Wyoming-Specific Rules

• Written test: two attempts in one day. WYDOT's current testing information says the same written test may be taken only twice in one day. The Wyoming Class C handbook covers signs, signals, pavement markings and Wyoming driving laws.
• Skills test waived with driver ed certificate. If you completed an approved driver education course, bring the certification card (with name, DOB, license number, and instructor/school signatures) to waive the skills test.
• Police officer overrules all traffic devices. Wyoming explicitly states that a police officers directions outweigh traffic lights and signs. Always follow the officer. this is tested.
• Wyoming speed limits. Interstate highways: 75 mph unless a designated segment is posted up to 80 mph. Non-interstate state highways: 70 mph. Where no other maximum applies: 65 mph on paved roads and 55 mph on unpaved roads. Urban/residential areas: 30 mph. Signed school zones: 20 mph. Blind intersections meeting the statutory sight-distance condition: 15 mph.
• Move Over law: 20 mph below the posted limit on qualifying two-lane roads. When the law applies and a same-direction lane is available, move to the lane farthest from the authorized vehicle using required visual signals. On a two-lane road posted at 45 mph or higher, reduce speed to 20 mph below the posted limit.
• Bicycle passing rule. When space allows, maintain at least 3 feet of separation. If there is not adequate space to pass, slow to the cyclist's speed and follow until there is room.
• Construction signs = black on orange. Wyoming manual states this specifically. black lettering on orange background marks construction zones.
• School zone = 20 mph; blind intersection = 15 mph when the statutory condition applies. These are separate Wyoming speed rules; a blind intersection is not limited to a school area.
• Flashing signals. Flashing red = full stop. Flashing yellow = proceed with caution. A flashing yellow arrow allows the indicated turn after yielding to oncoming traffic and pedestrians. Flashing red railroad signals require a stop.
• Wildlife crossing signs matter on Wyoming highways. Pronghorn, mule deer, elk, bison, and moose may enter the roadway. Reduce speed and scan the road edges when these warnings are posted.
