SEASONAL INFO

 When green is flashing…

Did you know the green cone in the human eye is the most sensitive, and has the longest wavelength? Green lights appear brighter and can be seen from farther away than other color lights, making them perfect for enhanced visibility in inclement weather conditions. That’s why the Iron County Road Commission has green lights on winter maintenance vehicles!

Green lights can make winter driving safer for motorists. Watch out for green lights on maintenance vehicles this winter.

 MDOT Winter Level of Service Definitions:

Priority #1- Orange Route

Provide maintenance service as appropriate under prevailing weather conditions, with a goal of providing a pavement surface over its entire width *generally bare of ice and snow.* This work may be accomplished using overtime as necessary.

Clearing the pavement bare of ice and snow over its entire width will be a continuous process during and after the snow event using overtime as necessary.

Priority #2- Blue Route

Provide maintenance service as appropriate under prevailing weather conditions, with a goal of providing a pavement surface *generally bare of ice and snow* wide enough for one-wheel track in each direction. This work may be accomplished using overtime as necessary during a winter storm event.

Clearing the pavement bare of ice and snow over its entire width will be accomplished as soon
as reasonably possible after the winter storm vent, without
working overtime.

A *generally bare of ice and snow* pavement is defined as a travel lane surface that is free from drifts, snow ridges, and as much ice and snow pack as practical.
