Farm Equipment Rules

Length, Width, Height and Weight of Farm Equipment and Loads
HTA 108, 109, 113

Farm equipment is exempt from the maximum width, length and weight rules when operated on a road singularly or in combination. These exemptions also apply to implements when towed with trucks. However, heavy farm equipment owners are potentially liable if an overweight vehicle causes damage to a highway or bridge.

Trucks, tractors and SPIH have no restriction on the length of the towed implements when one or more implements are being towed.

Wide farm equipment operating on the roads must:

  • keep right of the centreline, allowing other vehicles one-half of the travelled portion of the road.
  • keep right when being overtaken on the left.
  • keep right of the centreline when approaching the crest of a grade or hill or at a curve in the road or within 30 m (100 ft) of a bridge or tunnel when the driver's view is obstructed.
  • keep right of the centreline, within 30 m (100 ft) of a level railway crossing.

If large farm equipment is transported on licensed trucks and trailers, oversize/overweight permits may be required. For details, see the Oversize/overweight permits for trucks and trailers transporting farm equipment section of this guide located in the "Farm Truck and Trailer Rules" section.

Loose Fodder: Width restrictions do not apply to loads of loose fodder carried on trucks and trailers. Loose fodder includes round and rectangular bales of hay.

Weight on Reduced Roads and Bridges
HTA 114(3), 120, 122, 123 & Reg 615

Farm equipment, including mounted implements, are not subject to the reduced weight rules on "load reduced roads", Class B roads or bridges. However, heavy farm equipment owners are potentially liable if an overweight vehicle causes damage to a highway or bridge.
