Farm Equipment & Highways
Dimensions & Rules
Alberta Transportation establishes maximum vehicle weight and dimension limits to preserve highway infrastructure and to ensure the safety of the travelling public. This includes legal limits for any registered vehicle for travel on any public road, as well as the provision for movement of oversize loads under permit.
Over-dimensional farm equipment on a highway requires a permit. As per Section 4 #4(m)(iii) of the Commercial Vehicle Dimension and Weight Regulation:
4(m) operate farm equipment on a highway when
(i) the farm equipment, including any load, exceeds 2.6 metres in width,
(ii) the height of the highest point of the farm equipment, including any load, is greater than 5 metres from the surface of the highway, or
(iii) the overall length of the farm equipment, including any load, exceeds 30.5 metres;
Under the current legislation, the maximum length of farm equipment or combination of farm equipment is set at 30.5 metres or 100 feet.
Under Section 7 #6:
Width exceptions for farm equipment
