I got pull over today in Michigan for frost law

The Michigan frost law only pertains to roads other than a class A road (cement), if you keep in mind when you go on to an asphalt road you are on a class B road and the weight and speed restrictions come into play. If it is a gravl road stay of of it. The class B roads must have a sign referring to weight and speed restrictions.

Another little know law in Michigan is you are not allowed on a class B road with a 102 wide or 53 foot trailer any time of the year. There is a buffer distance from the class A road so you can make a delivery or pick up, I'm not sure of the distance but it has to do with the only way to get there. This time of the year in Michigan if you aren't sure you better call the shipper/receiver, those tickets can be in the thousands.

I must apologize for incomplete information. I posted this in a hurry and later realized I left out some very important information. If a road is an Interstate, a U.S. route or a Michigan State route, no matter what the road is made of, it is a class A road. I guess because of the better construction quality. County and local roads not so well built.

 

I find this interesting. There are no such regulations here in Alaska and the ground/roadbeds freeze and thaw cycles are much more severe than in the L48 , of course any regulation like the "frost law" would be silly considering the roads here are in a constant state of crap or construction, in fact, the differences in road quality are so great that I missed a turn by 200 miles in Montana once upon a time when I was driving (4 wheeler and trailer) from Minneapolis MN to Valdez AK, the road was so smooth and straight I was just kicking back and enjoying it so much I forgot all about my turn to head north for a boarder crossing. :smt102:smt046

"Frost law", something to remember for the future!

 

Probably something to do with the permafrost?

 

Yes, but seasonal freeze and thaw are several feet deep each year depending on when solid freeze temps hit and snowpack, if any at the time. Example; one winter, I think it was 97', the frost depth in Anchorage was 11feet deep due to lack of snow until February, unusual, but you get the idea. And, err....."border crossing" not boarder*, heh. I hate when look back and see that I had a brainfart misspelling event, typos excluded!

 

thats funny...but I do live out west.

 

So,

you're that OP everybody speaks of.

 

Such old news. Those spring laws have been in effect for ages. Really see nothing new.

 

May not be new to you but to some one who is not aware of it. well maybe we can save them a big ticket and fine. Always thought the exchange of good factual information was a good thing.

 

Class B roads DO NOT have to have a sign referring to it being a class B road, nor do they have to be posted as being frost restricted. The City or County must list the frost restricted routes on their website but that is all. In MI, all roads are class B unless designated class A or Special Designated (I/M/US Routes)

You are allowed 1 mile off of STAA routes, not class A roads. The off route allowance only accounts for width/length restrictions, not weight.

If it is a US/I/M route, it is a special designated highway not class A. Some of these roads are frost restricted as well.
