Lesson Learned

Post warning messages on DMS that describe how drivers should react to hazardous conditions rather than just notifying them of the hazard ahead. Presence of a DMS does not have a significant impact on the average change in driver speed until the fog condition becomes the most severe. Messages advising drivers on how to drive (e.g., "reduce speed") were found to be more effective than those solely warning of the presence of a hazard (e.g., "fog ahead").
