Patrick asked:

G-Town, I heard a rumor while I was at a Walmart DC in PA last week that Walmart is basically scaling back it's own truck operations to do more contracting out. Have you heard any such stuff?

I have not heard that, at least in the Pottsville D.C. WMPF is actually hiring here, in Johnstown NY and in Smyrna DE. I'll ask around though.

One point of clarity I want to make, since this seems to sometimes confuse even seasoned veterans who've been driving since God was a baby.

Those bridge law measurements, i.e. 40', 41', do NOT mean your tandems have to be set at that length, only that that is the furthest back they can be set.

I had this discussion last summer at a drop yard in CA with another Interstate driver. We were playing musical trailers, and as he handed me the bills and his scale ticket, I noticed he had the tandems set at 40', but when I looked at the scale ticket, his drives were 33880, and the tandems were 29400. When I asked him why he didn't slide them up and get some of the weight redistributed, he tried telling me you HAVE to run at 40' in CA no matter what. Five full minutes he argued this, even after I pulled the law up on my phone and pointed out that nowhere in there does it say that 40' is the minimum setting, only the maximum. I finally gave up, slide the axles up, and left.

The point here is to remember that maximum length does not also mean minimum length, or mandatory length.

Tandems:

Tandem Axles

A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

Fatsquatch the reference to Bridge Law as it applies to the 40' and 41' marks is irrelevant.

You are referring to individual State Kingpin Law and not Federal Bridge Law. The two laws are not interchangeable.
