Having grown up in the Montreal area, the problem in these towing zones, which MTQ doesn't explicitly state, is the road design, coupled with traffic speeds and volume. Many of these locations lack a breakdown shoulder to store stalled vehicles until assistance arrives. A stalled vehicle must sit in a live lane, vulnerable to a rear-end crash, awaiting assistance. Anyone outside the vehicles risks being struck or pinned between their vehicle and another. The law, the exclusive / expedited towing, and the blocker / arrowboard truck, are all attempts to mitigate the dangers associated with a short-sighted and deficient road design that likely dates back decades and would be extremely costly to fix. Credit MTQ for at least trying to avoid repeats of the fatalities which prompted the current program.
