Marginal note:Roof height — tractors
(6) Subject to subsections (7) and (8), “roof height” refers to the maximum height of a tractor, rounded to the nearest inch, excluding small accessories such as exhaust pipes and antennas, but including large accessories such as roof fairings, and measured with tires inflated to the manufacturer’s recommended cold tire inflation pressure and without occupants or cargo onboard.
