Taking two seconds to strap on a seat belt indisputably saves lives.
Yet researchers from a Virginia university found that more than a fifth of drivers still refuse to make that life-saving click.
Fortunately, the research can help guide law enforcement and education efforts to persuade more people to buckle up.
Researchers at Old Dominion University used a low-tech method to capture data. They stood at the side of roads throughout the state, clad in orange vests, clipboards in hand to eyeball passing drivers, making note of who was wearing a seat belt.
