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.

Speed limit signs are in kilometres per hour (km/h)

Trans-Canada Highway 1
Speed limit 100 km/hour
Route 28
Speed limit 80 km/hour
Route 635
Speed limit 50 km/hour

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.
  • 50 km/h is the maximum speed limit on a roadway that is located within an urban area, unless otherwise posted.

Highway and route signs

A provincial highway is identified by either a single-digit, 2-digit or 3-digit highway route marker

Trans-Canada Highway 1
Trans-Canada Highway 1
Route 28
Route 28
Route 635
Route 635

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.
