85% of car accidents worldwide happen in developing countries and 25,000 of the deaths involve tourists. The Center for Disease Control is asking Americans who are vacationing abroad to exercise extra precautions if they decide to drive a car during their stay. Very often roads in low incomes countries are poorly maintained and traffic laws are not sufficiently enforced. In case of an accident, emergency services may not be as fast as in developed countries, increasing the risk of a fatality. Adding to that the level of care may not be up to the level of US standards.
Making sure you know the local traffic rules or avoiding driving at night are among a CDC list of measures that may help minimize your risk of being injured in a car crash while you are on vacation.
