There was a time when truck driver Kevin Kimmel knew little about the scourge of human trafficking. That all changed when he pulled into a gas station [and] a kind of unusual" family recreational vehicle parked nearby caught his eye. Kimmel ... saw what he thought was a "minor female" appear from behind [a] curtain before abruptly disappearing. He immediately [called] the local sheriff. Police cars were soon on the scene. He later saw on the news that the woman he spotted was a 20-year-old sex trafficking victim. She had been lured away from her home in Iowa, held against her will and subjected to ... forced prostitution. Yet without the concern or quick thinking of Kimmel, she may never have been found. Truckers ... are increasingly seen as operating on the front line in the fight against human trafficking. Kimmel, who still drives a truck and speaks about his experiences at anti-trafficking events around the country, says that truckers tend to spend a lot of time in the places that victims pass through given the transient nature of their job. "[Traffickers] are constantly moving these people," he explains. "But when you're moving them, then you come into my world. If we know the signs and are vigilant then we can make a big piece of this problem go away." This is a point echoed by Kendis Paris of anti-trafficking charity Truckers Against Trafficking (TAT). Her organization seeks to educate truckers about what to look out for, how to report suspected incidences of trafficking and why it is important to do so.
