This is an astonishing fact: About every three hours, a person or vehicle is hit by a train in the U.S.

So the U.S. Department of Transportation (DOT) has launched a new print and television ad campaign entitled “Stop! Trains Can’t” aimed at young male motorists and encouraging them to act cautiously at railroad crossings.

The campaign is the latest in a two-year effort by DOT to reduce accidents and fatalities at railroad crossings around the country. The National Highway Traffic Safety Administration (NHTSA) and the Federal Railroad Administration (FRA) have partnered in the nationwide effort.

“The message is simple: Ignoring railroad crossing signs or attempting to race or beat a train can have deadly consequences,” U.S. Transportation Secretary Anthony Foxx said in a statement. “Hundreds of lives could be saved each year by simply following the rules.”

Although rail incidents have declined over the last 10 years, railroad crossing fatalities spiked in 2014. Last year alone, 232 people died in railroad crossing accidents, and approximately every three hours, a person or vehicle is hit by a train in the United States.

The $7 million media buy will target male populations aged 18 to 49 years old in states with the nation’s 15 most dangerous crossings, as well as in states where 75 percent of the crossing accidents occurred in 2015. Male drivers are involved in nearly 75 percent of all railroad crossing accidents.

The ad will run heavily in the following states: California, Illinois, Texas, Louisiana, Indiana, Ohio, Florida, Georgia, Missouri, New York, North Carolina, South Carolina, Kentucky, Alabama, Pennsylvania, Tennessee, Mississippi, New Jersey, Arkansas and Arizona.

By law, trains always have the right of way because they cannot swerve, stop quickly or change directions to avert collisions. A freight train travelling at 55 miles per hour takes a mile – the length of 18 football fields or more – to come to a stop once the emergency brakes are applied.
