It would be a last resort for the Police to evacuate people from their cars and this will be done via existing channels such as the radio and if possible emergency services/ Northants 4×4 telling people to leave their cars and seek shelter.
In this scenario, it may be that your community could accommodate these people that may be cold, tired and just need a place to shelter until they can carry on their journey.
On becoming aware of this type of emergency:
• Open a shelter
• Identify other resources that may support these people, i.e. food, water, a friendly face and a listening ear
• Make contact, if you can, with the Local Authority
