When going abroad, you don’t always think about the safety of the roads in the country you are traveling to – but you should.

Maybe you rely on a taxi or bus driver to negotiate the single-lane roads or mountain passes without guard rails.  Or you think there's no problem with getting behind the wheel in a foreign country.  But in some countries, simply crossing the street can be a risk. 

A report released this month by the University of Michigan's Transportation Research Initiative highlights the countries with the most car-accident deaths.

Drawing on 2008 data from the World Health Organization, the report compares international car-crash fatality rates against the mortality rates from other leading causes of death, like cancer and heart disease.

"The results of this study indicate that, in many parts of the world, fatalities from road crashes represent an unexpectedly large proportion of all fatalities," study author Michael Sivak told Live Science.

The worldwide average number of car-crash related deaths per 100,000 people per year is only 18, but in some countries that number is more than doubled. The U.S. comes in right around the middle, with 14 car-crash fatalities per 100,000 people. Auto accidents account for 1.8 percent of all deaths.

So strap on your seatbelt and take a look at the 10 deadliest countries to drive in.
