More than 135 people have died on Wyoming's highways so far this year, but what highway is the most dangerous in the Cowboy State?

According to a map put out by Geotab -- a company that specializes in GPS fleet management and vehicle tracking -- Interstate 80 in Wyoming sees over 17 fatal crashes a year.

Geotab also named I-80 as the most dangerous highway in Pennsylvania, Iowa, Nebraska and Nevada.

To determine the data, Geotab calculated a fatal crash rate that is based on the annual number of road fatalities and fatal crashes according to the National Highway Traffic Safety Administration, adjusted for the average daily traffic counts provided by the Federal Highway Administration.
