The police say they are keeping an open mind on the cause of this accident. Road conditions and the weather were both good when the coach veered off the dual carriageway and onto the embankment. Police are now trying to collect every piece of evidence from the scene.
One thing they will be looking at is whether there were more people on board the coach then there should have been. It was designed to carry 51 passengers and one driver, but we know that three people were killed, and 50 passengers were taken from the site to the hospital.
The three who were killed, haven't yet been officially named but we do understand that the driver was Colin Daulby, a man in his early 60s from Warrington. The other two people who have been killed, we understand were festival-goers, both in their 20s.
David Hannell, owner of Merseypride, the company that the crashed A3 coach belongs to, has said he felt "devastated" on hearing the news.
Speaking outside the company depot in Speke, Liverpool, he said:
Further to the news of one of our vehicles being involved in a tragic accident on the return journey from the Isle of White festival, myself and the company offer our heartfelt sympathy to all the families of the passengers involved.
We ourselves are devastated. I've been up all night worried sick about what's been happening."
Mr Hannell said the police had not told him anything and that "nobody seems to know what's happened".
He said this was the first serious accident Merseypride had had in 20 years and that the company had cancelled school jobs today because his drivers were not in the right frame of mind.
