If I do not have medical insurance, what problems can I face if in an accident?

Medical care&acciden. Most of the time medical insurance does not cover many accidental injuries like auto accident, workman comp covers on the jab accidents, if you have accident due to negligence of third party like a business or slip and fall due to negligence etc, the medical expences will be covered by their insurance policy.But if you have accident at your own place and/or your own negligence, you are responsible.
