The U.S. government is hoping teens can help fix the supply chain. Right now, there aren’t enough truck drivers, but a federal apprenticeship program will train thousands of new drivers as young as 18, allowing them to move cargo across states. (The legal age for truckers who drive across state lines is currently 21.) As many as 3,000 young truckers will be required to complete 400 hours of training before they’re allowed to drive solo. Some critics worry that teens might face a higher risk of accidents. But officials note that safety measures will prohibit apprentices from driving passengers or hazardous materials, and they must stay under 65 miles per hour. And trade groups argue that the program is necessary: “We are very concerned about our ability to continue to deliver to the entire country,” says Nick Geale, a vice president at the American Trucking Associations. The program isn’t an overnight solution, he adds, but it will introduce drivers to the work force earlier and to the roads more safely.
