The broom types do seem to work better than do the solid ones, on the back of any vehicle. The Alaska Hwy is paved, but most of it is not the type pavement many from the lower 48 or southern Canada are used to driving on, around where they live or generally travel. Much of the Alaska hwy is a process, that they call "chip and seal" which consists of a heavy grade of asphaltic oil, spread over the gravel road base, then a layer of crushed stone (gravel) is placed on top of this, then more oil and more gravel, till they get it the thickness they want. For a few weeks after this is done, there will be loose gravel, especially on both outer edges of the road and down the center section. In time this will work its way into the pavement or get worked off the side of the road. It is a process that works fairly well in the north country, not as expensive as a hot mix of asphalt and the use of paving machines. Pus the average road crew has the equipment, to lay chip and seal. Just takes a grader, an oil tank to put in the back of a truck with a spray boom on it and some dump trucks to haul and drop the gravel on the oil.
If every driver would remember the physics lessons they had in class, about every action has an opposite and equal reaction, much less damage would occur to vehicles. The gravel is just laying there, not doing anything but enjoying the sunshine and the scenery. Till a vehicle comes down the road. Depending on the speed of the vehicle, will depend on the speed of the rocks/gravel, as it is slung off the tires. Going slow, the rocks will also be going slow, and may not even bounce on the road. Drive fast or meet someone driving fast and damage will occur. If both meeting vehicles are running at 100 kph, then the resulting impact of the rock with glass or paint, will have the kinetic energy of a rock traveling at 200 klicks per hour, if only the rock was moving.
No one has any control over the other drivers, but you/we, do have control over your own vehicle, if you are the driver. The driver is the only one, that can decide how the toad or trailer, being pulled, is going to survive the trip. The vast majority of drivers on the Alaska Hwy, seem to understand this concept, but there are always a few that just don't get it. I think a lot of it has to do with where a person learned to drive and their experience driving larger vehicles. I have talked to some RVers, that their diesel pusher was the first vehicle, larger than their four door sedan they drove most of their adult lives. For some that learned to drive in large urban areas of North America, seem to think the term slowing down, means to drop back down to the posted speed limit. This works on many outside roads, unless you see the red and blue lights on behind you. But it won't work on the Alaska Hwy and other secondary roads in North America. I will now put my soap box back in the closet. LOL
For those that are used to driving on secondary roads in their state or province, they won't have any problems with the Alaska Hwy or the feeder roads attached to it.
