Amending O. Reg. 413/05

(Vehicle Weights and Dimensions — For Safe, Productive and Infrastructure-Friendly Vehicles)

1. Ontario Regulation 413/05 is amended by adding the following section immediately before the heading “Preconditions for Vehicle Combinations to be Designated Combinations”:

Dimensional deviations from designated combinations 1, 2 and 3

4.1 (1) Until January 1, 2020, a vehicle combination shall be deemed to be designated combination 1 if the semi-trailer,

(a) was built before 2006;

(b) is not more than 14.65 metres long; and

(c) meets every requirement of subsection 3 (1) to be a semi-trailer in designated combination 1 except for the dimensional limits for wheelbase, effective rear overhang, inter-vehicle-unit distance and track width.

(2) A vehicle combination shall be deemed to be designated combination 2 if the semi-trailer,

(a) was built before 2006;

(b) is not more than 14.65 metres long; and

(c) meets every requirement of subsection 3 (1) to be a semi-trailer in designated combination 2 except for the dimensional limits for wheelbase and track width.

(3) A vehicle combination shall be deemed to be designated combination 3 if the semi-trailer,

(a) was built before 2006;

(b) is not more than 14.65 metres long; and

(c) meets every requirement of subsection 3 (1) to be a semi-trailer in designated combination 3 except for the dimensional limits for wheelbase and track width.

2. The Regulation is amended by adding the following sections:

Maximum allowable gross vehicle weights — single unit vehicles

36.1 (1) The following maximum allowable gross vehicle weights are prescribed for single unit vehicles for the purposes of section 118 of the Act:

1. For a two axle vehicle, 14,000 kilograms.

2. For a three axle vehicle, the weight in Column 2 of the following Table corresponding to the rear axle spacing in Column 1 of the Table.

3. For a four axle vehicle, 25,000 kilograms.

(2) A single unit vehicle whose maximum gross vehicle weight is within the maximum prescribed under subsection (1) is exempt from sections 116, 117 and 118 of the Act.

(3) In this section,

“single unit vehicle” means a commercial motor vehicle used for,

(a) the transportation and dumping or spreading of sand, gravel, earth, crushed or uncut rock, slag, rubble, salt, calcium chloride, snow, ice or any mixture thereof, asphalt mixes or scrap metal, or

(b) the transportation of raw forest products. 

Exemption from all maximum weights — fire apparatus

36.2 A fire apparatus is exempt from sections 116, 117 and 118 of the Act if the fire apparatus does not exceed the axle unit, axle group or gross vehicle weight ratings specified by the manufacturer.

3. Schedules 1, 2 and 3 to the Regulation are revoked and the following substituted:

Schedule 1
Designated Combination 1 — Tractor Fixed Axle Semi-Trailer

Configuration Description

Designated Combination 1 is composed of a tractor and a single semi-trailer. The front axle of the tractor is a single axle with single tires. The drive axle of the tractor is either a single or tandem axle. The semi-trailer has one axle unit that is either a single, tandem or tridem axle.
