This infographic uses the definition for rural roads provided by Transport Canada and the Canadian Council of Motor Transport Administrators (CCMTA), including:
(a) primary or secondary highways, as well as local roads, or
(b) a speed limit at the collision site exceeding 60 km/h.
In Alberta, New Brunswick, Manitoba, and Saskatchewan “urban” includes any area within the corporate boundaries of a city, town, village or hamlet and “rural” includes any area outside of what is defined as “urban.”
