Description: The Wizard CB Alert System was quite effective at warning truck drivers about upcoming road conditions. Sixty-three percent of the truck drivers that had their CB tuned to channel 19 as they passed the paint crew heard the Wizard CB Alert message and 41 percent stated that the CB message was their first indication that they were approaching the paint crew. The system reached a large portion of the target audience and passed on information that was important to its listeners. Many drivers voiced their approval of the system, showed their support for its continued use in the future, and even suggested additional situations where the systems use would be helpful.
