Speaking of big rigs, the trucks in Michigan are often equipped with additional axles. Pup trailers-- and with equally many axles-- are also used extensively. What's the deal? Must be for weight distribution, and keeping the roads as best-maintained as possible. Read somewhere that the state does not receive federal highway funds, as well. Anyone know more? The fuel tankers in particular look huge. Begs a related question. Wonder how heavier apparatus-- ladder trucks-- affect road conditions in cities? And what costs more over time, fixing the roads or operating lighter ladders? That's what happens on vacation, endless musings.
 





Based on observations around Detroit, and through-state observations, such trucks appear to be hauling overweight cargo. Such as steel loads. Regular “box trucks” are all regular axle count, however.

I was wondering what my exwife was using to get around town these days. All those extra axles/wheels help her distribute ahem “weight”.

And Mike, glad the trip is going well so far! Thanks for the updates!

I work for a public safety software company that has several MI police departments as clients. I had to show them our mobile citation module recently and the axle weight issue came up. MI allows trucks to operate at up to 164,000 lbs (most other states allow up to 80,000 lbs), but have very strict requirements on the actual weight of each axle, which varies with distance from other axles. They claim that extensive testing and research by MIDOT shows that it is not the overall weight of the truck that impacts road deterioration, but the weight distribution. After driving on some roads in Michigan earlier this year, I’m not sure I agree…
