OK, I found a page that works.
Most drivers must follow the HOS Regulations if they drive a commercial motor vehicle, or CMV. In general, a CMV is a vehicle that is used as part of a business and is involved in interstate commerce and fits any of these descriptions: Weighs 10,001 pounds or more Has a gross vehicle weight...
www.fmcsa.dot.gov
And it DOES mention the updates in 2020, one of which allows the 2hr weather permit.
Now IM/HO that cuts 2 ways.
A) It gives a driver the ability to slow down and take time as needed.
B) But if 11 hours of routine driving is max safe, then 13 white knuckles is OK?
It's still gotta be WAY better than these guuys still trying to run 70 on icey roads and puting everyone at risk.
Catch tho is that you will now git a late start tomorrow as you still need the 10 hrs off, so ....
Down at the bottom of that page - it states that the HOS is applicable to anyone "commercial" over 10K# basically.
Not just CDL drivers.
That is not listed as a 2020 change, so it must have always been that way.
