On Monday afternoon, at around 3:30 PM, a massive collision left 4 dead and at least a dozen injured in Laval.\nThe crash occurred on a busy stretch of Highway 440 in Laval, a route known for being dangerous. Following the report, La Presse interviewed many people who denounced the highway for having lanes that allow people to dangerously merge at the last minute.\nFrançois Bonnardel, Quebec's transport minister, has announced that immediate changes will be made to the lane markings on highway 440.\nAccording to CJAD, the crash was caused by a vehicle colliding into another while merging into the exit lane very late.\nOther reports indicate that the cars involved were a small car, which collided into a larger truck. The two vehicles then collided into another truck.\nDrame sur l'A440 ouest à Laval: Au moins six véhicules - dont deux poids lourds - impliqués dans une violente collision.

This, says the Transport Minister, will make an area that has seen a dozen crashes since 2013 a little safer.\nBonnardel also announced that, once Sécurité Québec releases their report on the incident, which they should do in the next month, additional steps may be taken to make the area safer.\nSécurité Québec has already interviewed many witnesses, but they are asking for the public's help in piecing together the sequence of events.\nPeople who witnessed the crash, and the moments preceding it, are asked to contact the Sécurité Québec at 1-800-659-4262.
