How do I use DriveWindow with navigation?
Use DriveWindow to compare route weather and departure times before you leave, and your navigation app for directions during the drive. Check official road sources for closures and restrictions.
Why compare departure windows?
Weather risk can change by hour. Leaving earlier or later may reduce exposure to heavy rain, snow, low visibility, high wind, freezing conditions, night driving, or alerts.
How does DriveWindow use traffic in route weather planning?
DriveWindow uses traffic-aware route ETA to estimate when you will reach each weather segment, then ranks departure windows by weather risk. Use official road and navigation sources for live incidents, construction, and closures.
What weather risks does DriveWindow check?
DriveWindow checks route-level risk for rain, snow, wind, visibility, freezing conditions, weather alerts, and night driving across sampled points along the route.
Can I use DriveWindow for RV, motorcycle, or winter driving?
Yes. DriveWindow includes driving profiles for car, motorcycle, RV/trailer, cautious, and winter driving so the route risk can reflect the kind of trip you are planning.
How close to departure should I refresh the forecast?
Refresh the route forecast close to leaving, especially before long drives, mountain routes, winter trips, or severe weather days.
Does DriveWindow work for Canadian and cross-border routes?
DriveWindow is designed around Canadian, US, and cross-border route weather planning, including major highways, mountain corridors, weekend drives, and road trips.
