To give that a context, that is what I would call the heavy goods types of vehicles, such as trucking, the rail fleet, military types of vehicles, as well as other vehicles such as first responders—police, fire, ambulance, and that sort of area—as opposed to automotive, which is a separate group.
Pour mieux vous situer, c'est ce que j'appellerais les véhicules poids lourds, tels que les camions, les trains, les véhicules de type militaire, de même que d'autres véhicules tels que ceux de première intervention — police, services d'incendie, ambulances, et ainsi de suite — par opposition aux automobiles, qui forment un groupe distinct.
