The Utah Department of Transportation (UDOT) operates a network of roadside weather stations across the state. A number of these were equipped with Campbell Scientific CS120 visibility sensors.

During the 2013/14 winter, UDOT conducted a trial of a CS125 present-weather sensor. Following this trial they decided to upgrade 25 existing CS120 visibility sensors to CS125 present-weather sensors, and additionally purchase a further 28 CS125 sensors, making 53 in total. These were all operational by fall 2014 and allow UDOT to obtain rapid, reliable visibility and precipitation information from across the state.
