If you ask me personally, being in trucking for almost three years as a driver and being an owner-operator, mostly it was fatigue that was the major cause in my study that I saw. It's not only the driving for 12 hours or 13 hours straight, but sometimes, in the rest areas, there is not enough space to park. You eventually have to park illegally. That also leads to major accidents.
The government should look into that one too. On the 401, when I was driving it, it wasn't that busy, but after six or seven years, it's been super busy at night. If you travel the 401 at night, you see only trucks. Most of the trucks are not even parked inside the rest areas.
