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. James W.

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. Dale A Tabat Truck Freight Program and Policy Manager Washington State Departemnt of Transportation [log in to unmask]
