I think that's an issue, and I would imagine as well that someone must be either explicitly or implicitly looking at the accident performance of trucks versus other vehicles versus other pressures on the government, and making some determination that it is acceptable to exclude a larger part of the population than would be the case in other jurisdictions. You'd really have to ask them why they've chosen that, but I think that's part of the reason.
Je crois que ça pose problème, et j'imagine aussi que quelqu'un doit tenir compte, explicitement ou implicitement, du nombre d'accidents impliquant des camions, d'une part, par rapport à d'autres véhicules, d'autre part.
