This disclosure describes techniques for a navigation system to present suggested driving routes for a vehicle that may include roads subject to snow conditions. Under weather conditions that include snow, road conditions such as presence of snow on the road, road steepness, and road width are checked to determine the safety of a road and whether the road is preferable under the weather conditions. Described features inform and guide a user in determining a safe and quick route for a vehicle in potentially unsafe travel conditions.
