Alberta Road Signs: GDL Knowledge Test, Doubled Work Zone Fines & 30 km/h Playground Zones
What is the speed limit in an Alberta playground zone when lights flash? What happens to work zone fines when road workers are present? Should you pass a school bus showing amber lights? Playground zones are 30 km/h when lights flash. Work zone fines are doubled when workers are present. When amber lights flash on a school bus, approach ready to stop. The bus will stop shortly to load or unload passengers. Alberta uses a Graduated Driver Licensing (GDL) system: Class 7 Learner, Class 5-GDL Probationary, then full Class 5. Knowledge tests are at registry agent offices across Calgary, Edmonton, and Red Deer: find yours at alberta.ca/lookup/find-a-registry-agent.aspx.

1. Why Road Signs Matter in Alberta
Alberta roads stretch from Calgary's urban interchange network north through Edmonton's Henday loop, east on the Trans-Canada to Medicine Hat, and north on Highway 2 through Red Deer. Alberta operates a Graduated Driver Licensing (GDL) program: Class 7 Learner after the knowledge test, Class 5-GDL Probationary after the road test, full Class 5 after the Class 5 road test. Knowledge tests are taken at registry agent offices across the province. Find your nearest office at alberta.ca/lookup/find-a-registry-agent.aspx.
2. Road Sign Shapes and Colours in Alberta
Alberta uses the North American shape and colour system with metric speeds and distances. On Highway 2 between Calgary and Edmonton, on mountain approaches along the Trans-Canada, or on rural county roads, shape and colour register before text is readable. Know every row here before your registry agent knowledge test.

6. Traffic Signals in Alberta
Flashing red = stop at the stop line or crosswalk, then proceed when safe. Flashing yellow = slow down and yield. Alberta also uses pedestrian-activated flashing beacons: when lights flash, reduce speed to 30 km/h and yield or stop for pedestrians. All signal types are tested on the Alberta GDL knowledge test.
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 Alberta exam.
7. Alberta Pavement Markings
Yellow lines separate opposing traffic. White lines separate same-direction traffic. The Alberta exam tests 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
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 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)
Alberta: stop between 5 metres (15 ft) and 15 metres (50 ft) from the nearest rail; confirm all tracks are clear before crossing 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)
Lane changes permitted when safe
Solid white line (pavement)
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. Alberta Work Zone Signs
Orange signs with black lettering mark construction zones. they are temporary and override all normal signs. In Alberta, fines for moving violations in active work zones are doubled.
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.
- Alberta law doubles fines for many moving violations committed in active work zones.
- 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 Crossing Signs in Alberta
Round yellow sign = advance warning (first). X crossbuck = at the crossing (yield). Railroad signs appear in sequence. knowing that order is tested on the Alberta exam.
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 your vehicle behind this line. at least 15 feet from the nearest rail
- The round yellow advance warning sign is always the first sign you see before a crossing.
- The crossbuck (X-shaped sign) at the crossing itself acts as a yield sign. stop if a train is present.
- Never stop on the tracks. if traffic is backed up, wait until you can clear the tracks completely before crossing.
- School buses, vehicles carrying hazardous materials, and transit buses must always stop at all crossings. even if no train is visible.
Key test point: The round yellow sign = advance warning. The X crossbuck = at the crossing. Know the difference. both appear on the Alberta exam.
10. Alberta School Zone Signs
Passing other vehicles in either direction is prohibited in an active playground zone or school zone. Pentagon-shaped, fluorescent yellow-green. school zone traffic signs are unique in both shape and color. Speed limit is 30 km/h when flashers are active or children are present. Heavily enforced and frequently tested.
School Zone
School ahead. be alert for children, reduce speed
School Speed Limit
Speed limit is 30 km/h when children are present or when flashers are active
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
- The school zone speed limit of 30 km/h applies when the flashing yellow lights on the sign are active, or when children are visibly present.
- You must stop for a school bus displaying flashing red lights and an extended stop arm. in both directions on undivided roads.
- On roads with a true median or physical barrier, only traffic behind the bus must stop. oncoming traffic may proceed. A center turn lane does not count as a divider.
- Passing a stopped school bus is a primary offense in Alberta. fine up to $1,000 and possible license suspension.
- Always yield to crossing guards. their signal overrides 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 and Bike Signs in Alberta
Pedestrians have right-of-way at all crosswalks. marked or unmarked. Cyclists get 3 feet minimum clearance. Both sign types use fluorescent yellow-green and appear on the Alberta knowledge 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 the right-of-way in marked crosswalks. you must yield even if no sign is present.
- Alberta law requires motorists to give cyclists at least 3 feet of clearance when passing.
- 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 the Alberta GDL Knowledge Test
- Study the shapes first. If you can identify a sign by shape alone, you have already narrowed it down significantly.
- Use the official handbook. Download the Alberta Driver License Study Guide from the Alberta State Police website. it is free and covers all tested signs.
- Practice with flashcards. Quiz yourself on sign images, not just text descriptions.
- Do not confuse warning and regulatory. Yellow diamonds warn; white rectangles regulate. That distinction shows up on the test.
- Pay attention to school zones. Alberta strictly enforces 30 km/h school zone rules, and the test often includes questions about those signs.
- Know flashing signal rules cold. Flashing red = stop sign. Flashing yellow = yield. This is one of the most commonly missed questions.
- Learn yellow vs white lines. Yellow = opposing traffic. White = same-direction traffic. Simple rule, frequently tested.
- Orange always means construction. Any orange sign requires you to reduce speed and increase alertness.
- Take free practice tests. Sites like DMV.org and driving-tests.org offer Alberta-specific sign quizzes.
- Alberta-specific tip: Deer crossing signs are especially common on rural highways through the Alberta foothills, mountain, and northern rural corridors. slow down, these are active wildlife zones.
