Description of Road Conditions and Visibility
Road Conditions
| Road is bare | Road is snow covered |
|
|
| Road surfaces can be dry or wet, but are clear of snow or ice. |
Road surfaces are completely snow covered with no bare sections from one end to the other. |
| Road is icy | Road is partially snow covered |
 |
|
| Road surfaces are ice covered or snow packed due to either sleet or wet snow causing road surfaces to be slippery. |
Road surfaces have snow-covered or snow-packed sections. For example, there may be drifted sections of snow covering lanes or the road centre is bare. |
| Road is snow packed | Road is closed |
|
|
| Road surfaces are completely snow packed with no bare sections from one end to the other. |
Road is closed because road surfaces are impossible to travel along due to either continuous snow fall preventing snow removal or lane closures due to a collision. |
Road Visibility
| Visibility is good | Visibility is nil |
 |

| Visibility is good when you can see up to the horizon. | Visibility is nil when your range of vision is less than 50 metres. |
| Visibility is fair to poor |
|
| Visibility is fair to poor when your range of vision is reduced to 500 metres or less. |
