Alaska Road Signs & DMV Test: What Anchorage Drivers Miss
What happens if you drive through a Traffic Safety Corridor in Alaska? What is the school zone speed in Anchorage, Fairbanks, or Juneau? How close to a railroad crossing do you stop when a train is clearly visible and approaching? The Alaska Division of Motor Vehicles written test at ak.knowtodrive.com covers these rules. Traffic Safety Corridors with doubled fines, 20 mph school zones, and open range roads where livestock have right of way.

1. Driving Alaska Roads: Why Sign Recognition Is Critical Here
Alaska highway network connects Anchorage, Fairbanks, Juneau, Kenai, and Kodiak across some of the most remote terrain in North America. from the Alaska Range to the Inside Passage. The Alaska DMV written test covers traffic laws, safe driving practices, and highway sign recognition, all drawn from the official Alaska Driver Manual. Take it online at ak.knowtodrive.com anytime. Failing the test means you may retake it the following day. If your license has been expired for over one year or revoked, the written test is required.
2. Decode Any Sign Before You Read It: Shapes & Colors on the Alaska DMV Test
On Alaska remote highways, you may encounter a sign before you can read the text. shape and color tell you the category instantly. The Alaska DMV written test covers both. Know them cold before test day.

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. This distinction is one of the most commonly tested signal questions on the Alaska DMV written exam.
7. Pavement Markings on Alaska Roads: Lines, Arrows & Curb Colors
Yellow lines separate opposing traffic. White lines separate same-direction traffic. The Alaska DMV written test covers lane lines, road arrows, curb markings, and pavement symbols.
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

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 Turn Lane
Shared left-turn lane. used to begin or complete a left turn only
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)
Stop your vehicle completely behind this line at red lights and stop signs
Stop Here on Red
Painted instruction on pavement. stop at this marked line on red
Crosswalk lines
Mark the pedestrian crossing area. yield to pedestrians within these lines
Broken white line (pavement)

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. Work Zone & Construction Signs in Alaska: Traffic Safety Corridors and Doubled Fines
Orange signs with black lettering mark construction zones and are temporary overrides to all posted signs. Alaska designates certain highway stretches as Traffic Safety Corridors, fines for all traffic offenses in these corridors are doubled. Flag persons in work zones must be obeyed immediately; they use red flags or stop/slow paddles to direct traffic.
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
Work zone ends. normal speed and rules resume
Work Zone Headlights
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 a flaggers directions even if they conflict with existing signs or signals.
- Speed limits posted in work zones are enforceable even when workers are not present.
- Alaska designates Traffic Safety Corridors on selected highways. all traffic offense fines are doubled within these corridors.
- Never drive through or around a closed lane barrier. wait for a flagger or follow detour signs.
Key test point: Orange always means construction or work zone. If you see orange, reduce speed and increase following distance immediately.
9. Railroad Crossings in Alaska: When to Stop and How Far Back
Round yellow advance warning sign comes first. then the crossbuck at the crossing. Alaska law requires you to stop at railroad crossings when warning devices are active, a train is clearly visible and close enough to be a hazard, or a flagger directs you to stop. Never shift gears while crossing tracks. Never drive around lowered gates. it is against the law.
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
Stop here. Alaska requires stopping if a train is within close enough to be a hazard of the crossing
- The round yellow advance warning sign is always the first sign you see before a crossing.
- The crossbuck at the crossing acts as a yield sign. stop if a train is present or when warning devices are active or a train is clearly approaching the crossing.
- Never stop on the tracks. wait until you can clear them completely before proceeding.
- Never shift gears while crossing railroad tracks. especially important for manual transmission vehicles.
- School buses and vehicles carrying hazardous materials must always stop at all crossings.
- Never drive around lowered crossing gates. it is illegal in Alaska.
Key test point: Alaska law requires you to stop at railroad crossings when warning devices are active, a train is clearly visible and close enough to be a hazard, or a flagger directs you to stop. Once gates lower, it may be only 20 seconds before the train arrives.
10. Alaska School Zone Speed Limits and School Bus Laws You Must Know
Pentagon-shaped, fluorescent yellow-green signs mark school zones exclusively. Alaska sets the statutory school zone speed limit at 20 mph. Speeding in a school zone or playground crosswalk carries demerit points per the Alaska DMV schedule, the same as negligent driving. Violations are taken seriously statewide.
School Zone
School ahead. be alert for children, reduce speed
School Speed Limit
Alaska statutory school zone limit is 20 mph, speeding here carries demerit points per the Alaska DMV point schedule
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
- Alaska statutory school zone speed limit is 20 mph, local authorities may alter posted limits under 13 AAC 02.280.
- Failure to stop for a school bus while it is loading or unloading carries demerit points per the Alaska DMV schedule on your Alaska operators license.
- Drivers approaching a school bus from the rear must stop before reaching the bus when its red signal lights are flashing and the stop arm is extended. Remain stopped until the stop sign retracts and red lights are discontinued, or until signaled to proceed.
- Drivers meeting a school bus must reduce speed when amber warning lights are flashing, then come to a complete stop when the bus stops and red lights activate.
- On a highway with separated roadways providing two or more lanes in each direction, drivers approaching from the opposite direction are not required to stop.
- Always yield to crossing guards. their directions override all traffic signals and signs.
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. Pedestrian & Bike Signs in Alaska: Sharing the Road Safely
Pedestrians have right-of-way at all crosswalks. marked or unmarked. Bicyclists have the right to share the road and travel in the same direction as motor vehicles. Both sign types use fluorescent yellow-green and appear on the Alaska DMV written test.
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 the right-of-way in marked crosswalks. you must yield even if no sign is present.
- Bicyclists have the legal right to share the road with motor vehicles in Alaska. they are hard to see in traffic and have no crash protection.
- Check blind spots before turning, parallel parking, opening a door, or leaving a curb. bicyclists may be alongside you or approaching.
- 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 Alaska DMV Written Test: Traffic Safety Corridors & Sign Tricks
- Take it online. Alaska lets you sit the written knowledge test anytime at ak.knowtodrive.com, no DMV trip required for the written portion.
- Study shapes before text. On remote Alaskan highways you may see a sign before you can read it. shape and color tell you the category instantly.
- Know the statutory speed limits. Business district: 20 mph. Alley: 15 mph. School zone: 20 mph. Residential: 25 mph. All other roads: 55 mph. Selected highways may be posted at 65 mph.
- Memorize the Traffic Safety Corridor rule. Fines for all traffic offenses inside a designated corridor are doubled, this is a common test topic.
- Know the school bus rules. Drivers from the rear must stop when red lights flash and the stop arm extends. Drivers meeting the bus from the opposite direction must also stop. except on a separated highway with two or more lanes in each direction.
- Flashing signals are frequently tested. Flashing red = treat as a stop sign. Flashing yellow = slow down and yield.
- Railroad crossings: stop when required. Alaska requires you to stop if a train is within close enough to the crossing to be a hazard. and never to drive around lowered gates.
- Watch for wildlife. The Alaska Driver Manual specifically addresses moose, caribou, deer, and bear on roadways. especially at dawn and dusk. Wildlife warning signs are heavily tested.
- If you fail, retake the next day. The written test may be retaken the following day. The driving test fee through the DMV is $15.00, non-refundable if cancelled within 72 hours.
- Schedule your road test online at dmv.alaska.gov, available at DMV offices in Anchorage, Fairbanks, Juneau, Kodiak, Bethel, and more.
