I was driving round the M25 and there was an accident in front of me, I could still get round so I slowed down, put hazards on but drove past and carried on my way.
What's the actual protocol in those situations? I could see all the airbags were deployed, there's nothing I could do for the people inside and for sure getting out on a motorway is a bad idea.
But I feel like I should have done something different. Can anyone with knowledge enlighten me?
It sounds like you did. Too many people stopping to help would be a problem in itself. If you keep traffic flowing it means emergency services can get in easier and it reduces the risk of secondary accidents as inattentive drivers run into the back of stopped cars.
If you have medical training, that might be another issue and, I assume, doctors and the like would have been given more explicit advice for such circumstances.
