Before modifying a vehicle, better to know which modifications are permitted and which are prohibited.
A passenger vehicle may be modified to either improve its performance or change its appearance. The Société de l'assurance automobile du Québec (SAAQ) has to make sure that all vehicles using the road are safe, and comply with standards set by the Highway Safety Code and attendant regulations.
Police officers and carrier enforcement officers have the power to intercept a modified vehicle at any time, issue a ticket for a fine or demand that the vehicle undergo an inspection at a facility acting as agent for the SAAQ. Should the agent discover illegal modifications, the vehicle owner is required to rectify the situation.
If there is any doubt, the agent can have the SAAQ ask for an engineer's report to ensure that the modifications do not compromise the stability of the vehicle nor its overall safety. The vehicle can be put back on the road once the SAAQ is satisfied it meets standards.
