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.
Does DriveWindow show road closures or traffic?
No. DriveWindow focuses on weather-based route planning. It does not provide traffic incidents, construction, official road conditions, road closures, or turn-by-turn directions.
What weather risks does DriveWindow check?
DriveWindow checks route-level risk for rain, snow, wind, visibility, freezing conditions, severe 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.
