Heavy Vehicles

Installing and using front-view mirrors

Adding front-view mirrors is a simple, effective and inexpensive way to improve visibility in heavy vehicle blind spots.

Heavy vehicle blind spots can sometimes make it difficult to detect vulnerable road users, particularly at the front and on the forward right side.

A study conducted jointly by the Ministère des Transports, the SAAQ, the city of Montréal and the road safety team at the École Polytechnique de Montréal demonstrated that installing two front-view mirrors is a simple, effective and inexpensive way to improve visibility in these two problematic blind spots.

Targeted vehicles

Front-view mirrors are primarily intended for heavy vehicles that operate in urban environments. They can be installed on any heavy vehicles with conventional cabs, regardless of the shape or size of the vehicle or the hood.

Why install front-view mirrors?

Front-view mirrors allow heavy vehicle drivers to see what’s in front of their vehicles.

In combination with the mandatory rear-view mirrors, front-view mirrors give drivers an indirect view so that the problematic blind spots at the front and to the right of the cab are covered.

If the hood of the heavy vehicle is already equipped with convex rear-view mirrors, it is not recommended that they be replaced by front-view mirrors.
