How it fits
Road-weather observations and forecasts help authorities decide when and where crews are needed.
Operations
Priority-route plans, depots, contractor capacity and salt or abrasive storage shape response.
Canadian context
Coastal freeze-thaw, Prairie blizzards, mountain snow and northern cold create different challenges.
Limits and lifecycle
Even strong operations cannot make every road bare and dry during active storms, so current travel information remains important.
General infrastructure education only. Active road incidents, vehicle recovery and technical road work should follow responsible authorities and qualified professionals.
