Road Vehicle Mechanical Inspection Guide

This guide sets forth the mechanical inspection procedures and standards applicable to most vehicles.

This quick reference tool for mechanics and carrier enforcement officers describes mechanical inspection procedures and lists the minor and major defects most likely to be encountered in each of the 11 systems and categories of components covered.

The Highway Safety Code and the Regulation respecting safety standards for road vehicles served as the basis for the contents of this guide. Please refer to the Code and Regulation for all legal questions.
