Public service announcements can help reduce distracted driving incidents by educating people on the dangers. Any activity while driving, such as texting, eating, or adjusting the radio is a distraction. In 2012, over 3,000 people were killed and over 400,000 injured in crashes involving distracted drivers, a nine percent increase from 2011. While some critics argue PSAs may not reach all audiences or change behaviors, images in PSAs can be powerful and studies show campaigns have effectively changed unsafe driving habits when they promote strong anti-distracted driving messages that people can relate to.
