I know the NJ Turnpike does it through some aged variable message/speed
signs. They also exist on I-95 in Delaware.
Happy Holidays!

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.
