(2) An aggregate vehicle shall not be operated on a Class A Highway if the gross vehicle weight exceeds, in the case of a two axle aggregate vehicle, the result when 1,000 kilograms is subtracted from, or, in the case of an aggregate vehicle of three or more axles, the result when 1,500 kilograms is subtracted from, (a) the maximum weight permitted on the front axle under section 116 of the Act plus the sum of the maximum allowable weights for all other axle units of the vehicle or combination of vehicles as set out in section 116 of the Act; (b) the maximum weight permitted on the front axle under section 116 of the Act plus the sum of the maximum allowable weights for any two axle groups, three axle groups or four axle groups, or any combination thereof, as set out in section 117 of the Act plus the maximum allowable weight for any axle unit or units excluding any axle unit or units that are part of an axle group, as set out in section 116 of the Act; or (c) the maximum allowable gross weight prescribed in section 2. O. Reg. 355/96, s. 2. (3) For the purpose of calculating the maximum allowable gross weight of an aggregate vehicle powered by a tractor, and despite the definition of “front axle weight” in section 1, the front axle weight of the aggregate vehicle shall not exceed 6,500 kilograms.

It is not equipped with a liftable axle or a self-steering axle, whether raised, lowered or rendered inoperative. 3. If the single axle of the semi-trailer is liftable, the tractor, i. is not equipped with nor does it contain any device, whether remote or manual, that would allow the liftable axle to be controlled by the driver, and ii. is not equipped with automatic controls that activate other than when reversing. O. Reg. 668/00, s. 5. (3) The semi-trailer has the following characteristics: 1. It does not exceed 14.65 metres in length. 2. It has three axles, consisting of a front single axle and a rear tandem axle. 3. The inter-axle spacing between the single axle and the tandem axle is more than 2.5 metres but not more than 3 metres. 4. The single axle is a self-steering axle and is capable of turning 20 degrees in either direction. 5. The tandem axle has an axle spread of at least 1.2 metres. 6. The three axles automatically load equalize when the single axle is deployed. 7. The effective overhang does not exceed 35 per cent of the semi-trailer’s wheelbase. 8. If section 6 provides that it is to have a rear impact guard, it is equipped with a rear impact guard that meets the requirements of section 6. 9. If the single axle of the semi-trailer is liftable, the semi-trailer may be equipped with manual controls but may not be equipped with automatic controls that activate other than when reversing. O. Reg. 668/00, s. 5. (4) The semi-trailer bears its original compliance label and the notation “Reg 597(Ont) — 3”, signifying that the semi-trailer was manufactured to the specifications in subsection (3), is on that label or the semi-trailer’s manufacturer’s identification plate. O. Reg. 668/00, s. 5. (5) If the semi-trailer was not manufactured to the specifications in subsection (3), (a) it has been converted by a company authorized under the Motor Vehicle Safety Act (Canada) to apply a national safety mark or by an authorized dealer of such a company; (b) the person who converted it placed a label adjacent to the original compliance label indicating revised gross vehicle and axle weight ratings; and (c) the notation “Reg 597(Ont) — 3”, signifying that the trailer was converted to the specifications in subsection (3), is on that label. O. Reg. 668/00, s. 5. Self-Steer Quad Semi-Trailer
Rear Impact Guards
6. (1) This section applies with respect to every self-steer triaxle semi-trailer described in section 4 and every self-steer quad semi-trailer described in section 5,  (a) that has an axle unit that can slide or is fixed so that the rear of the rearmost tire is more than 0.3 metres in from the rear of the trailer; and (b) whose rear structure is more than 0.56 metres above the ground when the trailer is unladen on a level surface. O. Reg. 668/00, s. 5. (2) The trailer shall be equipped with a rear impact guard that consists of a single horizontal beam that is rigidly attached to the trailer and that, (a) extends to within 0.1 metres of each side of the trailer; (b) is not more than 0.3 metres in front of the rear of the trailer and is as close to its rear as practicable; and (c) is not more than 0.56 metres above the ground when the trailer is unladen on a level surface. O. Reg. 668/00, s. 5. (3) A rear impact guard on a trailer, as shown in Figure 3, that is manufactured after January 26, 1998 shall meet the standards for such a guard under United States Federal Motor Vehicle Safety Standard 224, which became effective on January 26, 1998, or a corresponding standard, if any, under the Motor Vehicle Safety Act (Canada).
