I looked thru lots of pages of their street signs, but this one, or anything similar was not shown. A friend thought it might be a weight limit, I also checked and there weren't any grades in the area. -Bill

In the Spring when road surfaces are weakened due to frost/thawing issues, there is often a reduction of axle weights on trucks to minimize the weights of loads hauled on these roadways. In this case, a 25% reduction of the load axle weight is in effect. It has nothing to do with grades.

Why do they single out 6xs?

But there is no indication for 25% less of what exactly? 80,000 lbs or 10,000 lbs? There was no other sign anywhere near that sign. Apparently its to be ignored.

75% of legal axle load.

not by trucks.we're in it right now.no gravel delivery,no septic cleanout,and good luck getting lumber delivered.

The sign looks like its permanent. you would think it would have a weight listed for someone to know if they should go down that road. Odd.

It is a tax levy.

But this is not a sign that is restricting total weight it is restricting the weight to 75% of your vehicles rated maximum which usually depends on the number and configuration of your axles.

Typically if you are driving a vehicle that has the potential to be loaded to or beyond maximum axle weight you know what that maximum weight is and this sign makes perfect sense. 75% of maximum weight - whatever that is for your truck and will depend on the number of axles you have and the tire configuration for each axle. It will be different total for a single axle truck which is a truck with two axles (front and single rear) vs a tandem axle truck which is a truck with three (front and two rear). There are trucks with two steering axles and two or more driving axles. The total maximum weight for the vehicle is different in each case and commercial drivers know what this is.

I am Canadian and have never seen that sign before. Learn something new everyday I guess

The sign could be in place for weeks , even months , lower section can be changed out to 50/60% .
Makes deliveries difficult but more acceptable than a complete closure to all vehicles over a certain weight.
Box truck shown is just a visual to indicate all commercial vehicles .

That would make complete sense if all trucks had the same axle weight. Say I have a truck with a 5 ton axle and another has a 10 ton axle. The guy with the 10 ton axle can have 7.5 tons and the guy with a 5 ton axle could only have 3.5 tons on his axle. But its fairly obvious the road can handle 7.5 tons, the guy in the small truck should ignore the sign then? Again, it makes no sense to have that sign without a weight attached for each axle like I have seen many times in the past, see attached pic. -Bill

PS. Ignore that the axle weight limit and the rest of the sign weights make no sense.

Alberta off major/main highways, usually on "thin membrane surface" and other non-asphalt concetre roads. You can see the difference when you go over to neighbouring SK (along the continuation of the same highway) where there are no seasonal axle weight limits. Nice ruts in the road that must run close to 3-4" deeper than the crown (or maybe even more). When I saw those early last June, I slowed down to a crawl. You'd almost think the RV will flip over if you run into one at speed.

Here's the road weight ban for a county near Edmonton.

Below is a web site that will help you understand why the first sign makes sense to a driver of a commercial vehicle. The number of axels, size and width of tire and number of tires on an axle are the factors that go into what the maximum legal weight a vehicle can carry on US and Canadian roads. If you drive such a vehicle you know what that weight is and it is different for every configuration. And yes if your small commercial P&D truck has only a single axle on the rear with only a single tire then you are restricted to 75% of your normal load on that particular road. That is in fact what the sign means and if it was a road across permafrost or ice I would very much believe it.

The three pictures with weights beside each picture only covers a very small percentage of the trucks on the road and does not consider all of the various possible, nor even the most common configurations. The per axle weight at the bottom of the sign is actually more useful, but does not consider all of the various and more esoteric possibilities. The percentage covers them all.
