What Is A 'Breach Of Duty Of Care' Under Tort Law?

A breach of duty of care is simply not abiding by a reasonable standard of conduct that would cause someone harm. And a breach of duty of care for example would be walking next to someone in a subway and just ignoring them maybe running maybe jogging through that subway car and pushing people over. That would be unsafe and that would be a breach of the duty of care you may not be intentionally trying to push people over but because you're trying to for example run a marathon in a train car you're going to cause damage to people and it's reasonably foreseeable that that's going to take place. So if you do that you're going to be breaching your reasonable duty of care to society.
