Depending on of the country you are travelling to, the consequences may vary in the event of an accident. There are countries that oblige you to take out a travel insurance policy if you want to go to them. If you are travelling within the European Union and you are European, you may have a health card that will entitle you to medical coverage with its limitations and guarantees. If, on the contrary, you have gone to a country outside the European Union and you suffer some kind of medical problem, you will have to assume the cost of medical treatment in the destination country, repatriation costs, etc. Moreover, travel insurance policies not only cover unforeseen medical events but also loss of luggage, flight cancellations and other eventualities. Taking out travel insurance is the most sensible option to be covered and minimise any costs in the event of an unforeseen event.
