* Semi-trailers and full trailers manufactured prior to July 1, 1988 that have not had
their running gear totally replaced may have a track width of less than 2.5 m.
** Lead semi-trailers equipped with two single axle units with an interaxle spacing
of between 1.86 m and 3.05 m can not exceed the maximum allowable gross
axle weight for a single axle unit.
*** This minimum applies to the interaxle spacing between the axle unit on a
semi-trailer and the adjacent axle unit on a trailer converter dolly.
Spacing less then 3.0 m are allowed, provided: - the sum of the weights of a
single axle semi-trailer and the converter dolly does not exceed the maximum
allowable gross axle weight of a tandem axle unit; - the sum of the weights of
a tandem axle semi-trailer and the converter dolly does not exceed the
maximum allowable gross axle weight of a tridem axle unit with an axle
spread of 3.0 m to less than 3.6 m
**** The sum of the gross axle weights of all axle units (maximum of 2 in contact
with the ground) on the full trailer can not exceed the sum of the gross axle
weights of the drive axle unit and the axle unit(s) of the lead semi-trailer.
Note:
The use of a trailer converter dolly equipped with a tandem or
Tridem axle is not permitted.
Note:
A-trains with trailer equipment manufactured prior to July 1, 1988
are allowed a maximum allowable gross vehicle weight of 56,500 kg. |

* Semi-trailers and Full Trailers manufactured prior to July 1, 1988 that have not had
their running gear totally replaced may have a track width of less than 2.5 m.
** This minimum applies to the interaxle spacing between the axle unit on a semi-
trailer and the adjacent axle unit on a trailer converter dolly. Spacing less than
3.0m can be allowed, provided: - the sum of the weights on a single axle semi
-trailer and converter dolly does not exceed the maximum allowable gross axle
weight of a tandem axle unit;
- the sum of the weights of a tandem axle semi-trailer and converter dolly does not
exceed the maximum allowable gross axle weight of a tridem axle unit with an axle
spread of 3.0 m to less than 3.6 m.
*** The lead semi-trailer, if equipped with two single axle units in contact with the
ground and with an interaxle spacing of between 1.86 m and 3.05 m, can not exceed
the maximum allowable gross axle weight for a single axle unit.
**** The sum of the gross axle weights of all axle units (maximum of 2 in contact
with ground) on the full trailer (C-dolly and second semi-trailer) can not
exceed the sum of the gross axle weights of the drive axle unit and the axle
unit of the lead semi-trailer.
Notes:
- The use of a trailer converter dolly equipped with a tandem or tridem axle
is not permitted.
- C-Trains with trailer equipment manufactured prior to July 1, 1988 are allowed
a maximum allowable gross vehicle weight of 56,500 kg.
- Notwithstanding section 28, subsections (2), (3), (6), (7), (9) and (10) of
Manitoba Regulation 575/88, where a C-train with a C-dolly: - satisfies testing
requirements determined by the National Research Council (Canada);
- displays, in a conspicuous place on both sides of the C-dolly, a label from the
manufacturer certifying satisfaction of those requirements, the gross vehicle
weight shall not exceed 60,500 kg on an RTAC Route.

Note:
Where a truck tractor, in combination with an end dump bulk
semi- trailer which was manufactured prior to April 1, 1982, is
driven or operated on an RTAC route or a Class A1 or Class B1
Highway and does not exceed the maximum prescribed
GVW for that type of vehicle on that class of highway, it shall be
deemed to meet the minimum "Interaxle Spacings" and the
