Lesson Learned

CV warnings are effective, but designers should be sure to give drivers actionable information along with a warning. Simply alerting drivers to upcoming bad weather conditions "did not prompt significant reductions in speed." However, when the system presented drivers with a warning and actionable information (e.g. a suggested speed reduction) drivers noticeably reduced their speed.
