3. Where a tire weight limit is expressed as weight per millimetre, the reference is to a millimetre of tire width.

4. A vehicle that is required to comply with subsection 109 (2) of the Act and which does comply with that subsection shall be deemed to be in compliance with the width limits in Schedules 1 to 13.

5. Maximum width shall be determined in accordance with subsections 109 (1), (3) and (5) of the Act.

6. Maximum semi-trailer length shall be determined in accordance with subsection 109 (10) and (10.2) of the Act.

7. A reference to a table in “HTA, Part VIII” means that the appropriate weight is that set out in the specified Table in Part VIII of the Act.

8. “Not controlled” means that no measurement is prescribed.

9. “Overall” refers to the total combination.

10. The prescribed weight of any axle unit with single tires is the sum of its individual maximum axle weights as specified in the Schedule under Individual Axle with Single Tires when the sum of those weights is less than the weight prescribed elsewhere in the Weight Limit Chart for the axle unit. O. Reg. 413/05, s. 37 (1).

(2) In Schedules 1 to 13,

“bed length” means the external measurement of a trailer from the front of its cargo carrying space to the rear of its cargo carrying space, but excluding any portion of auxiliary equipment or machinery that extends beyond the front of the trailer and that is not designed for the transportation of goods;

“drawbar length” means the longitudinal distance from the centre of the hole in the fifth wheel of a converter dolly to the centre of its eye or equivalent device;

“effective rear overhang” means the longitudinal distance from the turn centre of the trailer to its rearmost point, including any load;

“hitch offset” means the longitudinal distance from the turn centre of the foremost semi-trailer to the articulation point of the hitch used to tow the rearmost trailer;

“kg” means kilograms;

“m” means metres;

“max” means maximum;

“min” means minimum;

“quadruple spread” means the longitudinal distance between the centres of the foremost and rearmost axles of the quadruple axle;

“self-steer” means self-steering axle;

“tandem” means tandem axle;

“track width” means the width of an axle across the outside faces of the tires measured at any point above the lowest point of the rim;

“tridem” means tridem axle;

“tri-drive” means tri-drive axle;

“wheelbase” means the longitudinal distance,

(a) from the centre of the kingpin to the turn centre in the case of a semi-trailer,

(c) from the centre of articulation of the turntable to the turn centre in the case of a full trailer. O. Reg. 413/05, s. 37 (2).

38. Omitted (revokes other Regulations). O. Reg. 413/05, s. 38.
