In Maine we have permanent flashing signs on all interstates advising a
maximum speed of 45 as opposed to the normal 65 in inclement weather,
these can be turned on in specific locations depending on if the
conditions are limited to a certain area, these are controlled by
MaineDOT. We have no requirements for chains.

Subject: Inclement weather speed limit reductions
The Washington State DOT is interested in information on the following:
1) Are there any states that decrease the posted speed limit in the
event of inclement weather (snow and ice in particular) and if so how is
that accomplished? Is the speed limit decrease applied to specific road
segments only or can it be incorporated across a state's entire highway
system? Looking for related information for all traffic in general and
freight trucks in particular.
2) Are there any urban areas that issue chain requirements for freight
trucks during snow/ice conditions?
Thank you for any input.
