To my knowledge not in Alabama.  If we have area that become dangerous we put up signs.  We don't Have a policy that reduces the speed.

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.
