Road-Building Machines

Regulation Number(s):
Instrument Type:
Bill or Act:
Highway Traffic Act
Summary of Proposal:
The Ministry of Transportation (MTO) is reviewing the current definition of a road-building machine (RBM) under the Highway Traffic Act (HTA). RBMs are exempt from many obligations under the HTA and other legislation that relies on the HTA for vehicle classifications.

MTO is looking to the public for feedback on this proposal. We will be hosting two information sessions.

1. Tuesday, March 10, 2015 9:00 am.
Holiday Inn Toronto International Airport
970 Dixon Road
Toronto ON M9W 1J9

2. Wednesday, March 11, 2015 9:00 am.
Holiday Inn Express and Suites
1325 Seymour Street
North Bay ON P1B 9V6

Please RSVP to MTO with the number of attendees at the following email address

The goal is the develop a new definition to distinguish between traditional types of RBMs built to operate on construction and maintenance right of ways and those built on truck chassis able to operate at highway speeds, meet federal manufacturing requirements and are for multi-purpose use. Vehicles that do not meet the new RBM definition will be classified as commercial motor vehicles, and as such, will be required to comply with safety regulations.

Historically, RBMs required these exemptions because they were not manufactured to, nor could they meet, federal manufacturing safety standards for vehicles operating on a highway. Over the years, manufacturers began building these machines on a truck chassis. Since these types of vehicles are manufactured to comply with federal safety standards and are capable of operating at highway speeds, they are very similar to other commercial vehicles operating on the highway and there is no longer any reason to have them exempt from many of the requirements under the HTA.

Additionally, the ministry is proposing to limit the speed of construction and maintenance vehicles that will meet the new definition of an RBM.

This proposal will be of interest to commercial vehicle operators, municipalities, owners of RBMs including mobile cranes, concrete pumpers, sweepers and hydrovacs, those in the construction or road-building industry.
