Tractor
Wheelbase: On legal sized loads, tractor wheelbase (from center of steer
axle to center of drive axles) cannot exceed 244 inches without the Annual

oversize or overweight permit, tractor wheelbase is allowed to increase to a

Tridem
Drive Tractor: Tridem drive tractors are not legal unless all axles drive and
are evenly spaced. Lift axles are not allowed. If a lift axle is chained up,
wheelbase rules apply.

carry more than 20,000 pounds total (10,000 pounds per axle).
Lift
& Flip Axles: Alberta does not recognize lift axles unless they meet very
specific guidelines outlines in the Annual Equipment Exemption Permit for
Trailer Lift Axles. Otherwise they must be chained up securely. Flip
