Speed limit signs
Speed limits do not indicate the maximum speed drivers should travel. They are the maximum speed permitted when conditions are ideal. Any speed that is unsafe for the current conditions is illegal.
Maximum speed 50 km/h 
Maximum speed 100 km/h 
Maximum speed 80 km/h
Speed limit signs are in kilometres per hour (km/h).
Unless otherwise posted
- 100 km/h is the maximum speed limit on a provincial highway located outside an urban area.
- 80 km/h is the maximum speed limit on a provincial highway located inside a corporate limit of a city.
- 80 km/h is the maximum speed limit on a roadway that is located outside an urban area.
Alberta highway route marker (oval with wild rose)
A provincial highway is identified by either a single-digit, two-digit or three-digit highway route marker.
A local road generally would not have a route marker but could be identified by a name, such as Irricana Road, a township road, such as TWP RD 52, or a range road, such as RGE RD 252.
- 50 km/h is the maximum speed limit on a roadway that is located within an urban area, unless otherwise posted.
Note: Municipalities may have bylaws on speed limits that place maximum limits different than the information presented here. Be aware of local laws and pay attention to all signage and posted speed limits.
