Two people died Monday morning after a semi-trailer truck carrying sand collided with a small white car at the intersection of Rang Saint-Vincent and Route 148 (Route Arthur-Sauvé) in Mirabel. According to the Mirabel Police Service, the victims were a 45-year-old female driver and a 63-year-old male truck driver, both of whom died at the scene.
Why did the collision occur on Route 148?
Inspector Jacques Caza stated the accident appears to be linked to driver distraction. The impact was described by Caza as very violent, forcing both vehicles into a ditch. A security perimeter remained in place through Monday evening while city employees recovered sand spilled during the crash.
How dangerous is this sector of Mirabel?
The Mirabel Police Service reports a pattern of high speeds on Route 148. Inspector Caza noted that small streets crossing this road create risks because vehicles travel very quickly, necessitating full stops before entering the thoroughfare.
Three previous fatalities occurred in this area since late May:
- A 15-year-old on a moped.
- A 50-year-old motorcyclist killed in a head-on collision with a heavy vehicle.
- A 24-year-old who died from injuries sustained in a car accident in late June.
What is being done to reduce accidents?
The government ministry recently installed three new stop signs in the sector. Additionally, the City of Mirabel launched the “Roulez Zen” awareness campaign to slow down traffic.

A city press release stated that officials are closely monitoring the sectors of Saint-Janvier, Saint-Augustin, Mirabel-en-Haut, and Domaine-Vert-Nord due to increased traffic and growth. With the start of construction holiday vacations, Inspector Caza warned that drivers must exercise even greater caution.
What may happen next?
Police are continuing an active investigation into the Monday crash, which may lead to further findings on the exact cause of the distraction.
