Rear-view cameras

Rear-view camera testing

Two buses equipped with rear-view cameras are currently being tested as part of a one-year pilot project. This trial will help us assess the cameras’ performance and test their reliability in a wide variety of conditions.

The cameras are installed at the front of the bus, one on the left and one on the right.


One of the first in North America

Some European cities already have buses with rear-view cameras. In North America, the STM is one of the first transit provider to conduct testing with this type of system.

The project reflects the STM’s goals of continuous improvement in road safety and aligns with the City of Montréal’s Vision Zero initiative.


Rear-view cameras provide better visibility for drivers, even in difficult conditions. Their positioning allows drivers to maintain their visual scanning habits at the wheel.


Expected benefits of rear-view cameras

The technology comes with many benefits:

Reducing vehicle blind spots

Improving visibility in difficult conditions such as darkness, bright sunlight, tunnels, rain and snow

Being less vulnerable to damage from collisions than traditional rear-view mirrors due to their compact size and higher placement on the vehicle

Improving safety for all road users

Innovative cleaning system

For maximum efficiency, STM teams designed an ingenious device to keep the camera lenses clean. Using the pneumatic system already present on all STM buses, it directs a jet of forced air into the camera lens. The device can be activated on demand or automatically.
