If you are a Drivewyze PreClear subscriber you are entitled to the free add-on service of Safety Notifications. This service was recently upgraded to include Mountain Corridors across the United States. For truckers driving through the mountains, this handy notification system will send an alert to your device about upcoming grade warnings, brake check areas, and runaway ramps. Alerts include more than 100 Safety Zones and 5% or higher downgrades. Coverage is available on interstates in 20 states.
Here is a video from Drivewyze showing how the notifications work:
