What is the difference in meaning between a crash and an accident

If you drive a car into something or someone else, you have had/caused a crash. You have not caused an accident because there was nothing 'accidental' about it

If you crash into somebody in a car, sometimes it could be on purpose because you are not being responsible enough for yourself and your own actions- whilst and accident can be where you are simply stressed or saddened to where you have no control and you may accidentally bump into another car
