Family badly injured by speeding driver

My family came to the UK to spend time with my family and i for Christmas. Whilst they were driving home through Belgium they were struck by a speeding driver spinning them into a concrete barrier on the motorway at 100km/ph. All the occupants of the car broke their backs and and have other various injuries ranging from broken ribs to head injuries and internal injuries. They are now unable to work for the foreseeable future and i am looking to support them with living costs and trying to recuperate costs occurred from the accident such as the hospitalization in Belgium and the transport of all four back to Poland which currently stands at over £2000, so they could be cared for properly as the language barrier in Belgium proved too much for them to be able to help.  Any donations will be greatly appreciated. Thank you.
