Why Navigation Apps Are Not Helpful During Winter Weather Events
Many motorists plug their travel destination into a navigation app to find the fastest and most efficient route possible. While these navigation apps can be useful, it is best to put them away during winter weather events and turn to https://www.sd511.org/ and the SD511 mobile app for vital traveler information regarding the latest road conditions.
