It may depend on the car, but, based on anecdotal evidence observed over the last couple of weeks, trucks/buses seem more likely to become trapped because they can't get past a slippery surface (usually a hill). I (in my small car with snow tires) had no trouble getting past a couple of trucks whose wheels were spinning.
Weight is more of a factor for getting stuck in snow (from volume more than slippery-ness), so full trucks/buses often do better than light/empty vehicles.
