Wyoming Road Signs: WYDOT Exam, 80 mph Interstates & Bike Law
What is the speed limit on Wyoming interstates and turnpikes? What happens if you miss 13 or more questions on the Wyoming knowledge test? 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. Miss 13 or more questions: 3-day wait to retest. Wyoming law requires slowing to the cyclists speed and following until a clear lane is available. not squeezing past. A police officers directions outweigh any traffic signal or sign.

1. Wyoming 80 mph Interstates, 3-Day Retest Rule 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. Written test + vision screening required. Fail: 24-hour wait. Miss 13+ questions: 3-day wait. Skills test can be waived with an approved driver education certificate. A police officers 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.

6. Wyoming Traffic Signals: Police Override Rule and What the WYDOT Knowledge Test Covers
Flashing red = stop sign. Flashing yellow = yield. Wyoming knowledge test covers all signal types. Wyoming explicitly states that a police officers directions outweigh traffic lights or signs, always obey the officer, not the signal. Flashing red lights or crossing gates at railroad crossings are listed as required stops under Wyoming statute.
Standard Traffic Lights
Steady Red
Come to a complete stop behind the stop line. Wait until green.
Steady Yellow
Prepare to stop. the light is about to turn red. Do not speed up to beat it.
Steady Green
Proceed if the intersection is clear. You must still yield to pedestrians and cross traffic.
Green Arrow (left)
You may proceed only in the direction of the arrow. Oncoming traffic is stopped.
Yellow Arrow (no left)
The protected turn is ending. Prepare to stop or yield if you have not yet entered the intersection.
Red Arrow (no left)
Do not turn in the direction of the arrow. Wait for a green arrow or green light.
Green. no left arrow
Proceed straight or right. left turn not permitted on this phase.
Opposing Traffic Extended Green
Oncoming traffic has an extended green phase. wait before turning left.
Flashing Signals
Flashing Red
Treat as a STOP sign, come to a complete stop, then proceed when safe.
Flashing Yellow
Treat as a YIELD sign, slow down, look carefully, and proceed with caution.
Flashing Red Beacon
Overhead flashing red beacon. treat as a stop sign. Come to a full stop, then proceed when safe.
Flashing Green Arrow
You may turn in the direction of the arrow after yielding to oncoming traffic and pedestrians.
Pedestrian Signals
WALK / White Walking Figure & DONT WALK / Orange Hand
White walking figure = pedestrians may cross. Orange hand = do not start crossing; if already crossing, finish quickly.
Flashing Orange Hand + Countdown
Crossing phase is ending. Pedestrians who have started may finish; others should not begin.
Key test point: Flashing red = stop sign. Flashing yellow = yield. A police officers directions outweigh any traffic signal. always follow the officer. All tested on the Wyoming WYDOT knowledge exam.
7. Wyoming Pavement Markings: RXR Stop Line Before Railroad Tracks and Open Range Road Edge Lines
Yellow lines separate opposing traffic. White lines separate same-direction traffic. The WYDOT knowledge test covers lane lines, road arrows, curb markings, and pavement symbols. including the RXR pavement marking followed by a stop line on railroad crossing approaches (stay behind the stop line while waiting for a train), and edge lines on Wyoming open-range rural highways.
Line Colors
Yellow lines
Separate traffic moving in opposite directions
White lines
Separate traffic moving in the same direction, or mark the edge of the road
Line Types
Broken yellow line (Single)
Passing allowed when safe on your side
Solid yellow + broken yellow
Passing allowed only on the broken-line side
Double solid yellow lines
No passing in either direction
Broken white line
Lane changes permitted when safe
Solid white line
Do not cross. lane edge, crosswalk, or stop line
Double solid white lines
Do not change lanes. often used near intersections or toll areas

Center Turning Lane (sign)
Overhead or posted sign marking a shared center left-turn lane
Pavement Symbols & Special Markings
Arrows in lane
Indicate which direction(s) you may travel from that lane
Stop line (wide white bar)

Do not cross. lane edge, crosswalk, or stop line
Double solid white lines (pavement)
Do not change lanes. often used near intersections or toll areas
Railroad crossing markings (X + RR)
Advance warning of tracks ahead. painted on pavement before the crossing
Diagonal yellow lines (gore area)
Do not drive in this area. marks a traffic island or diverging zone
Bicycle lane marking
White painted lane reserved for cyclists. do not drive or park in it
HOV / Carpool lane diamond
Lane restricted to vehicles with 2 or more occupants during posted hours
Yellow curb
No parking or stopping at any time
Red curb
No stopping, standing, or parking. fire zone
White curb
Passenger loading/unloading only. brief stops permitted
Key test point: Yellow lines always separate opposing traffic. White lines always separate same-direction traffic. This is a foundational rule that appears on nearly every DMV exam.
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 be alert
Flagger Ahead
A person is directing traffic. obey their signals immediately
Workers Ahead
Road workers are present. slow down and be prepared to stop
Active Work Zone
You are in an active work zone. fines doubled, drive with extra caution
End of Active Work Zone

Headlights required in this work zone
Lane Closed Ahead
A travel lane ends ahead. merge early and do not pass in the closed lane
Road Closed
Road is completely closed. do not enter, follow detour signs
Orange barrels / cones
Mark lane boundaries and closures in active work zones
Channelizing devices (barricades)
Direct traffic around obstacles or closed areas
- 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: on interstates, merge to the farthest lane from a working vehicle with lights activated; on two-lane roads, reduce speed by at least 20 mph.
Key test point: Orange always means construction or work zone. If you see orange, reduce speed and increase following distance immediately.
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.
Advance Warning Sign
Railroad crossing ahead. the first sign you see. Begin slowing down.
RR Crossbuck Sign (X-shaped)
Located at the crossing itself. yield to trains. Treat as a yield sign if no gates or lights.
Railroad Crossing (at crossing)
Marks the exact railroad crossing location
Crossing Gates
Lower when a train is coming. never drive around or under a lowered gate
Pavement markings (X + RR)
Painted on the road surface before the crossing as an advance warning
Flashing Red Lights
A train is approaching, stop and wait. Do not proceed until lights stop and it is fully clear.
Stop Line
Wyoming: stop behind the stop line on the approach; RXR pavement markings precede it; stay behind the line while waiting for the train to pass; flashing red lights or gates = mandatory stop
- 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.
Key test point: RXR pavement markings precede the stop line at Wyoming railroad crossings. Stay behind the stop line while waiting. Flashing red lights or crossing gates = mandatory stop. All tested on the Wyoming knowledge exam.
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. School zone speed is 20 mph. At a blind intersection. where you cannot see cross traffic. approach at no more than 15 mph. When meeting or overtaking a stopped school bus with flashing red lights, Wyoming requires stopping from either direction. On undivided roads, traffic in both directions must stop. On a divided roadway, only same-side traffic stops.
School Zone
School ahead. be alert for children, reduce speed
School Speed Limit
Wyoming school zone = 20 mph; blind intersections = slow to 15 mph; school bus red lights = stop from both directions on undivided roads; divided road = same side only
Speed Limit Lights Flashing
Speed limit applies only when the flashing lights are active
School Crossing Ahead
Crosswalk used by schoolchildren ahead. yield to crossing guard and students
- Wyoming school zone speed is 20 mph. At a blind intersection where you cannot see cross traffic, reduce speed to no more than 15 mph before entering.
- 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
Pedestrians have right-of-way at crosswalks in Wyoming. stop for blind pedestrians carrying a white cane or guided by a guide dog. Wyoming bicycle passing rule is specific: when space allows, maintain at least 3 feet of separation. But if you do not have a clear and empty lane to pass, do not attempt it. slow to the cyclists speed and follow until there is room. Both sign types use fluorescent yellow-green and are tested on the Wyoming 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 Wyoming crosswalks. Stop for blind persons carrying a white cane or using a guide dog. this is a required stop under Wyoming statute.
- 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: Pedestrians always have right-of-way at crosswalks. marked or unmarked. This rule appears on virtually every state DMV exam.
12. How to Pass Wyoming WYDOT Knowledge Test: 80 mph Rules, the Follow-Do not-Pass Bike Law and 3 WY-Specific Rules
- Miss 13+ questions = 3-day wait. Wyoming retest penalty is among the strictest in any state. Miss fewer than 13: wait 24 hours. Miss 13 or more: wait 3 days. Prepare thoroughly using the Wyoming Class C handbook at dot.state.wy.us.
- 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: 80 mph / 75 mph. Secondary highways: 70 mph. Residential/business: 30 mph. School zones: 20 mph. Blind intersections: 15 mph.
- Move Over law: 20 mph reduction on two-lane roads. On interstates, merge to the farthest lane from a working/emergency vehicle with lights on. On two-lane roads, reduce speed by at least 20 mph. This is Wyoming law.
- Bicycle follow rule. not just 3 feet. If you do not have a clear empty lane to pass a cyclist, you must slow to the cyclists speed and follow until you have room. The 3-foot minimum only applies when space allows. Not squeezing past is the primary rule.
- Construction signs = black on orange. Wyoming manual states this specifically. black lettering on orange background marks construction zones.
- School zone = 20 mph; blind intersections = 15 mph. Two separate speed thresholds in school areas. Know both.
- Flashing signals. Flashing red = full stop. Flashing yellow = slow and yield. Flashing red at railroad crossings = stop (listed as a required stop in WY statute).
- Wildlife on the highway is extremely common. Pronghorn, mule deer, elk, bison, and moose crossing signs are not decorative in Wyoming. these collisions are one of the most common crash types in the state. Slow significantly when you see these signs.
