Lesson 02 — Alberta Road Signs
Identify the four major sign categories in Alberta: regulatory, warning, school/playground and construction.
Learning objectives
- Recognize the colours and shapes of Alberta road signs (TAC standard).
- Differentiate between regulatory, warning, school/playground, and construction zone signs.
- Identify Alberta-specific signs (cold weather, wildlife, oversize loads).
- Anticipate sign-related questions on the Class 7 Knowledge Test.
- Compare Alberta signs to those in BC and Ontario.
1. The four major sign families in Alberta
Alberta uses signs aligned with the Transportation Association of Canada (TAC) Manual of Uniform Traffic Control Devices for Canada (MUTCDC), applied through the Alberta Traffic Safety Act and the Use of Highway and Rules of the Road Regulation. Four families:
| Family | Shape / Colour | Example |
| Regulatory | Square / circle, black on white, sometimes red | Stop, Speed Limit, Do Not Enter |
| Warning | Yellow diamond, black symbols | Curve, Pedestrian crossing, Wildlife |
| School / playground | Fluorescent yellow-green pentagon | School zone, Playground zone |
| Construction | Orange diamond / rectangle | Workers ahead, Detour, Reduced speed |
2. Regulatory signs
Regulatory signs give legally binding instructions. Disobeying any of them is a violation of the Traffic Safety Act.
2.1 Common regulatory signs
- STOP (red octagon): mandatory complete stop before the white line or crosswalk.
- YIELD (red and white triangle, point down): slow down and yield.
- Speed Limit (white rectangle): Alberta defaults — 50 km/h urban, 80 km/h rural, 100-110 km/h highways.
- Do Not Enter / Wrong Way: entry forbidden.
- No U-Turn / No Left Turn: red circle and slash through the symbol.
- One Way: white arrow on a black background.
2.2 Alberta-specific regulatory signs
- HOV diamond: on Calgary's Stoney Trail and Edmonton's Anthony Henday Drive.
- Snow plow / winter maintenance signs: «Do not pass snow plow» — Alberta highways often display this.
- Oversize loads warning: common on Highway 63 to Fort McMurray for oil-sands convoys.
According to the Alberta Traffic Safety Act, Section 115: «A person shall not operate a vehicle at a speed in excess of the speed limit indicated by a sign».

3. Warning signs
Yellow diamond signs warn of hazards ahead. Examples relevant to Alberta:
- Curve ahead with recommended speed.
- Pedestrian crossing.
- Bridge freezes before road — critical in Alberta winter (Highway QE2 overpasses).
- Watch for wildlife — deer, moose, elk, sometimes bear. Highways 16 (Yellowhead) and 11 see frequent collisions.
- Slow-moving vehicle (orange triangle) — common on rural roads with farm equipment.
- Strong winds — frequent near Pincher Creek (Crowsnest Pass).
4. School and playground zones
| Zone | Speed limit | Hours |
| School zone | 30 km/h | 8:00 AM – 9:30 AM, 11:30 AM – 1:30 PM, 3:00 PM – 4:30 PM, on school days |
| Playground zone | 30 km/h | 8:30 AM to 1 hour after sunset (or as posted: usually 8:30 AM – 9:00 PM) |
Strict Alberta rule: Speeding in a school or playground zone leads to double fines. A 50-in-30 ticket = ~$233 + 4 demerit points. For Class 7/Class 5-GDL drivers, accumulating 4+ demerits leads to a 1-month licence suspension.
5. Construction zones
Construction zones in Alberta use orange signs. Speed limits in construction zones are usually 50-70 km/h. Fines for speeding in construction zones are tripled when workers are present.
- Workers ahead — person with shovel.
- Flagger ahead — person with STOP/SLOW paddle.
- Detour — black arrow on orange.
- Lane closed with chevrons.
6. Differences with BC and Ontario signs
- Alberta school zones use 3 time slots (BC and Ontario use one continuous 8 AM – 5 PM window).
- Alberta highway speed limit: 100-110 km/h max (BC has 120 km/h on Coquihalla).
- Alberta does NOT mandate winter tires on any highway (BC does on designated routes).
- Alberta uses orange signs for construction (same as BC and Ontario).
Memory tip: «Yellow = Warning, Red = Stop/Forbidden, Orange = Construction, Green = Direction/Info, Blue = Services, Brown = Tourism, White = Regulation» — same colour code across all Canadian provinces.
Practical scenario — driving Edmonton to Jasper
You drive west on Highway 16 (Yellowhead) from Edmonton to Jasper. You see a yellow diamond with a moose symbol, a white rectangle «MAXIMUM 110», an orange diamond «WORKERS AHEAD 70», and a green sign «JASPER 80 km». What should you do?
Answer: watch for wildlife (dawn/dusk), reduce to 110 km/h, slow to 70 km/h in the construction zone (and more if workers present), continue toward Jasper.
7. Common mistakes
- Confusing school and playground zone time windows.
- Speeding in construction zones — fines tripled.
- Ignoring «Do not pass snow plow» signs in winter.
- Not slowing for slow-moving vehicles (orange triangle) on rural roads.
8. Points to remember
- Stop = red octagon (mandatory full stop).
- Yellow diamond = warning.
- Yellow-green pentagon = school / playground.
- Orange = construction zone.
- Alberta school zones: 30 km/h in 3 time slots.
- Playground zones: 30 km/h, 8:30 AM to 1 hour after sunset.
- Construction zone speeding fines tripled if workers present.
