I live in a snowy area. Road conditions can get bad really quick. I’ve noticed that Google Maps’ live traffic information is a gateway to gauge road conditions. Green lines would mean likely plowed areas while yellow and red lines mean cars are slowing down because of poor conditions. I suppose there’s a chance it could be actual traffic but when you know the weather is bad, it’s far more likely to show yellow and red lines because of road conditions.
Google Maps can be helpful with road conditions
